Float Switch Replacement for an Existing Pump Panel

Float switch replacement in an existing pump panel changes how the panel senses water level while keeping the motor starters, overloads, disconnects and wiring that are still serviceable. A troublesome float switch does not automatically mean that every component in the pump control system has reached the end of its useful life.

If the existing power components remain suitable, it may be possible to update level sensing while retaining much of the existing control equipment. The retrofit still needs to begin with the existing sequence.

Document What Every Float Does

Before removing anything, identify each float and the condition it controls.

A commercial sump may have separate points for pump stop, pump start, second pump start and high level alarm. Other systems may use floats for filling or low level protection.

Do not assume wire color identifies function.

Trace the circuits and compare them with the panel drawings. If the drawings no longer match the installation, update them before designing the replacement.

Keep Pump Power Separate From Level Sensing

The level sensing circuit tells the system what the water is doing. It does not necessarily carry the motor load itself.

Large pumps commonly operate through motor starters or contactors sized for the equipment.

Documentation for the WLC-9100 duplex pump-down level controller notes that its relays can be used as pilot relays for properly rated pump contactors.

That means the existing power hardware may remain part of the final design when it is in good condition and properly rated.

Match the Existing Sequence

A replacement level system should reproduce the required operating logic rather than simply copying the physical locations of old floats.

Waterline Controls offers simplex and duplex pump-down controllers, with high and low alarms available on selected models. Their dry contacts can report status to an existing control system.

If the old arrangement alternated pumps or used staged starts, select the new controls around that requirement. On the WLC-9000 A/C duplex pump-down controller, the A version is sequenced and the C version alternates. On the WLC-9100, A and B are sequenced and C and D alternate. Confirm which suffix matches the existing panel logic.

Check Sensor Cable Routing

Electronic sensing introduces its own installation requirements.

Waterline Controls installation instructions call for the sensor cable to run in earth-grounded metal conduit, separate from the conduit that carries high voltage lines, to reduce unwanted interference.

A retrofit is a good opportunity to correct questionable cable routing left from previous modifications.

Decide Which Signals Go to SCADA or BMS

Older float panels may provide only local lights or alarms.

An updated level control can add dry contacts for remote monitoring without requiring the BMS to control the pump sequence itself.

Possible points include pump calls, high level, low level and controller power loss, depending on the selected model.

Keep the local automatic sequence capable of doing its job even if remote monitoring is unavailable, unless the project design intentionally says otherwise.

Test Each Level Point

Commission the retrofit one function at a time.

Raise or simulate the water level and verify pump start, second pump operation, alarms and shutdown. Test manual controls separately.

Then verify the remote signals. For point-list details, see which BMS points a water level controller should report.

Where the selected controller has a press-to-test button, follow the model’s instructions to run the test sequence and confirm relays and connected devices respond.

Float Switch Replacement Controllers for Existing Panels

Waterline Controls manufactures frequency-based float switch replacement controllers for commercial sumps, lift stations, wastewater systems and other pump applications. Existing motor starters and panel components may be retained when the design and condition permit. For the cooling tower side of the same problem, see why float switches fail in cooling tower level control. Call 480-905-1892 to discuss the existing sequence, pump sizes, panel arrangement, alarm requirements and sensor locations before planning your retrofit.

What Happens to Level Control During Power Loss?

A level control’s power loss response is the state its valves, pumps and alarm contacts take when the controller itself loses power. It is one of the conditions a level control specification should address before equipment is installed.

The correct response is not identical for every application. A cooling tower fill valve, a wastewater pump and a fire water tank may have very different priorities. What matters is that the desired state is intentional and documented.

Define the Safe State for the Application

For many ordinary automatic fill systems, the conservative response to loss of controller power is to stop filling.

A common fail-safe arrangement uses a fill valve that closes when controller power is lost. That prevents a fill command from remaining active after the controller is no longer available to stop it.

That logic should not simply be copied into every project. The engineer must consider which failure creates the greater risk.

Pump Down Systems Have Different Concerns

A sump or lift station cannot remove incoming water if its pumps have lost electrical power.

The level controller may therefore be only one part of a larger emergency strategy involving standby power, remote alarms and available storage volume.

A high level alarm should be located with enough margin to provide a meaningful response if normal pumping is unavailable.

Power loss and high water are different conditions and should be reported separately where the control system allows it.

Send Power Loss to the Remote System

The WLC-5000 fill controller provides four remote dry contacts: one power loss contact and three contacts for its control functions. Its submittal identifies the normal and power loss state of the power contact.

That allows the BMS to identify that the controller itself is unavailable rather than assuming the water is normal. For the full list of points worth sending, see which BMS points a water level controller should report.

Fire Protection May Require Different Logic

Fire protection water storage deserves separate consideration.

The FPT-50 fire protection water level controller offers an optional Paragon valve arrangement that lets the fill operate automatically during power loss.

That illustrates why the phrase fail-safe cannot be reduced to one universal rule.

The approved fire protection design, adopted standards and authority having jurisdiction determine the required behavior for that project.

Consider Normally Open and Normally Closed Devices

The valve or relay state matters as much as the controller program.

A normally closed fill valve typically requires energy to remain open. Losing that energy therefore stops the fill.

Other arrangements may be intentionally designed to fail in another position.

The electrical drawings should show the relay state, the controlled device and the expected result during power loss. Labels such as normally open should always be interpreted in relation to the actual relay or valve being described.

Test Power Failure Deliberately

Do not wait for the first outage to discover how the system behaves.

During commissioning, simulate loss of controller power and observe the valve or pump response. Confirm the BMS or fire panel receives the expected signal.

Restore power and verify the system returns to normal operation without creating an unintended pump start, overflow or missed alarm.

Record the result in the sequence of operation.

Power Loss Contacts, Relays and Fire Panel Signals

Waterline Controls manufactures frequency-based electronic level control systems with power relays, alarm functions and model-specific dry contacts for BMS, BAS and fire panel integration. Because the correct power loss response depends on the application, the safest approach is to define it before equipment is ordered. Call 480-905-1892 to review the desired sequence, controlled device, alarm points and remote signaling requirements for your project.

Pump and level sensor at a sump illustrating water level control pump short cycling

Why Water Level Control Pumps Short Cycle

Short cycling means a pump starts again before it has finished a useful run, often many times an hour. Those repeated starts can overheat motors, wear relays and contactors, increase maintenance and hide a level sensing problem. In a tank, sump or lift station, the correct run time depends on inflow, pump capacity and the distance between the start and stop levels.

The first step is to confirm that the cycling is abnormal. Then the operator can separate a pump problem from a sensor, controller or hydraulic problem.

Record What the System Is Doing

Count how many times the pump starts during a normal hour and note how long each run lasts. Record the water level at start and stop, whether both pumps are affected and whether the pattern changes during rain, process demand or heavy building use.

Xylem describes a case in which unrealistic level spikes caused two pumps to start and stop hundreds of times per day. Because both pumps were affected equally, the evidence pointed toward the level sensor or controller rather than two pump failures.

Check the Distance Between Start and Stop Levels

A pump needs enough drawdown between the start and stop points to complete a useful cycle. If the sensing points are too close, a small change in level can stop the pump almost immediately. Water returning through the discharge pipe may then raise the level enough to start it again.

Review the operating band, tank dimensions and pump rate before moving sensors. A wider separation may reduce cycling, but it must not allow overflow, low water damage or an unsuitable process level.

Look for Turbulence and Wave Action

Water entering near the sensor can create splashing, waves and temporary changes. A float may bounce, or another sensor may see movement that does not represent the average level.

Inspect the sensor location while the system operates. In a cooling tower basin, surge tank or active sump, the answer may involve repositioning the sensing assembly, using a suitable time delay or selecting a controller designed to compensate for wave action. Waterline Controls states that its cooling tower level controls are designed to compensate for wave action in a basin. That is surface stability for fill control, not the start to stop distance a pump needs.

Inspect Sensors and Wiring

Mechanical floats can catch on piping, cables, grease or debris. Probe systems should be checked for secure mounting, correct depth and intact wiring. Loose terminals, damaged insulation or intermittent power can create false transitions.

Do not assume the pump has failed because it receives repeated start commands. Check whether the controller LEDs or BMS points show rapid level changes. If the indicated level jumps while the water remains steady, focus on the sensing and control circuit.

Check Valves and Flow Conditions

A leaking check valve can allow discharged water to return after the pump stops. Restricted piping can cause the pump to move less water than expected. In a fill application, a valve that leaks through may raise the level after the controller has closed it.

Compare the actual drawdown or refill time with previous operation. A major change may point to a blocked line, worn pump, altered inflow or valve problem rather than a controller setting.

Make Sure the Pump Is Properly Sized

An oversized pump may remove the available water so quickly that each run is extremely short. An undersized pump may run almost continuously during peak inflow and still allow the level to rise. Pentair’s residential sump pump FAQ notes that oversizing and undersizing can shorten pump life through short cycling or continuous running. The same mechanisms apply to commercial sumps, where the motor’s rated starts per hour still govern.

Pump selection, operating level and control range have to work together. Changing one without reviewing the others may move the problem rather than solve it.

Test the Complete Sequence

After repairs or adjustments, observe several full cycles. Confirm start, stop, alarm and power loss indication. For duplex systems, verify the specified lead and lag sequence and, where applicable, pump alternation.

Document the final sensor locations and normal cycle time. A future technician can then identify a real change instead of guessing what the system used to do.

Level Controllers for Duplex Pump Down Stations

Waterline Controls supplies frequency-based electronic level controllers for tanks, wells, cooling towers, sumps, wastewater and dual pump applications, including the WLC-9100 dual pump down level controller for duplex stations. Its stainless steel sensing probes, local status lights, alarm options and dry contact outputs are designed for reliable level control without moving floats.

Lead lag duplex pump control with WLC-9100 dual pump controller, alternation and high level alarm

Lead Lag Pump Control System Planning Guide

A two pump station needs more than a second pump sitting beside the first. The control sequence has to decide which pump starts first, when the second joins it and what happens if the water continues to rise. A well planned lead lag arrangement spreads operating hours, handles changing inflow and gives the facility a clearer response when one pump cannot keep up.

Understand Lead, Lag and Alternation

The lead pump is the first unit called during a normal cycle. The lag pump starts at a higher level if inflow exceeds the capacity of the lead pump or the level continues rising. When demand falls, the pumps stop according to the selected sequence.

Alternation changes which pump becomes lead on the next cycle. Grundfos explains that alternation divides operating hours between two pumps, while the second can start when demand exceeds the capacity of one. This avoids one pump carrying nearly all routine use while the other remains idle.

Choose the Shutdown Sequence

Two common questions are whether the pumps should stop one at a time as the level falls or stop together at a lower point. Both approaches can be useful, depending on the tank, inflow and desired drawdown.

Waterline Controls offers WLC-9100 dual pump controller variations with sequence on and sequence off operation, as well as versions in which both pumps stop together. Alternating models change the first pump each cycle so wear is shared.

The sequence should be shown on the control drawing. Operators need to know which level starts the lead pump, which starts the lag pump, where the high alarm activates and how the pumps shut down.

Set Levels Around the Actual System

Sensor positions cannot be chosen from tank height alone. The engineer should consider useful volume, inflow rate, pump capacity, minimum submergence, freeboard and the time available before overflow.

The lag point should be high enough to avoid unnecessary two pump operation during ordinary cycles but low enough to give the second pump time to respond. The high alarm should provide meaningful warning rather than activating when the station is already in danger.

A narrow control band can create short cycling. A band that is too wide may allow excessive level variation. The correct range balances pump protection, storage and process needs.

Plan for One Pump Being Unavailable

A duplex station is often selected for redundancy, but redundancy only exists when the controls can respond to a failed or unavailable pump. The design should consider overloads, disconnect position, maintenance isolation and whether the lag pump can become lead when the other unit is out of service.

The operator should also know whether an alarm confirms that a pump was commanded or that it actually ran. A command signal does not prove that water was moved.

Include a High Level Alarm

The high level alarm is the final warning that normal pumping has not controlled the water. It should be visible locally and, where required, reported to the BMS, SCADA system or remote alarm panel.

Waterline Controls combines dual pump down control with a high alarm in the WLC-9100. Its models provide dry contacts for remote signaling, including power loss and control functions. Remote point names should distinguish lead pump, lag pump, high alarm and controller trouble where those signals are available.

Commission Under Realistic Conditions

Startup testing should confirm more than manual pump rotation. Raise or simulate the level through each operating point. Confirm the lead pump starts, the lag pump joins at the correct point, the alarm activates and the pumps stop in the intended order.

Repeat the cycle to verify alternation. Test power loss indication and BMS or SCADA points. If the system uses check valves, verify that backflow does not restart the pumps immediately after shutdown.

Document Normal Operation

Leave a sequence of operation in the facility records. Record sensor heights, pump assignments, relay functions and expected cycle behavior. This makes future troubleshooting much faster.

Operating staff should know how to place one pump out of service without defeating alarms or leaving the station without automatic control.

Specify Lead Lag Control With Waterline Controls

Waterline Controls manufactures dual pump level controllers for lift stations, sumps, wastewater systems, tanks and other pump down applications. The WLC-9100 provides several sequencing and alternation choices with high level alarm and remote signaling options. Call 480 905 1892 to review pump capacity, sensor levels, sequence and BMS requirements for your project.

How To Reduce Water Waste?

Most people do not waste water on purpose. It usually happens in quieter ways, a toilet that keeps running, an irrigation system that waters when it should not, a faucet that drips just enough to ignore, or a building system that no one is watching closely. That is why reducing water waste is rarely about one dramatic change. It is more often about noticing the little losses and fixing them before they become expensive habits.

The good news is that real water savings usually come from practical steps, not complicated ones. Once you know where water is being lost, it gets much easier to do something about it.

START WITH LEAKS

If there is one place to begin, it is leaks. A small leak can seem harmless for weeks or months, especially if it is hidden behind a wall, under a sink, or somewhere outside that no one checks very often. But over time, those small losses add up.

That is why regular monitoring matters. Instead of waiting for a high bill or visible damage, it makes far more sense to catch unusual water use early. In homes, that may mean checking toilets, faucets, hose bibs, and irrigation lines. In commercial buildings, it often means paying closer attention to system data, usage patterns, and after-hours flow. When water is being used at the wrong time, that is usually telling you something.

PAY ATTENTION TO IRRIGATION

Outdoor watering wastes an enormous amount of water when it is not managed well. Sprinklers run during the heat of the day, water blows onto pavement instead of landscaping, or a timer keeps watering after a rainstorm because no one updated the schedule.

A better approach is to water only when needed and to make sure the system is actually helping the landscape instead of the sidewalk. Smarter controllers, weather-based scheduling, and routine inspections can make a real difference. Even simple adjustments, like changing watering times or fixing a misaligned sprinkler head, can cut waste more than people expect.

UPGRADE OLD FIXTURES AND CONTROLS

Sometimes water waste is built into the equipment itself. Older toilets, faucets, showerheads, and irrigation controls often use more water than necessary simply because they were designed to older standards. Replacing outdated fixtures with more efficient options can reduce waste without making everyday use feel inconvenient.

The same idea applies in larger buildings. If a property is still relying on older monitoring methods or no monitoring at all, waste can go unnoticed for far too long. Better controls give owners and managers a clearer picture of what the building is actually doing.

USE DATA, NOT GUESSWORK

One of the biggest reasons water waste continues is that people assume they would know if something was wrong. Often, they would not. Many leaks are hidden, and many forms of waste happen gradually enough that they look normal until the bill arrives.

That is where monitoring becomes valuable. Real-time water tracking, alerts, and usage reporting help turn water management from guesswork into something measurable. Instead of reacting after the damage is done, you can respond when the pattern first changes. For businesses, schools, hospitals, and large facilities, that shift can save both water and money.

MAKE WATER EFFICIENCY PART OF ROUTINE MAINTENANCE

Water waste is easier to control when it becomes part of normal maintenance rather than a once-a-year concern. Checking for leaks, reviewing usage trends, inspecting irrigation, and replacing worn components should be part of the regular rhythm of running a property.

That does not just protect water. It protects budgets, buildings, and equipment too. Waste is rarely just a water problem. It is usually a sign that something else needs attention.

READY TO GET SERIOUS ABOUT WATER WASTE?

If you want to reduce water waste without relying on guesswork, Waterline Controls offers solutions that help monitor water use, detect leaks, and improve visibility across building systems. The right setup can help you catch problems earlier, use water more efficiently, and make smarter decisions about your property. Reach out to Waterline Controls to learn more about practical water monitoring and leak detection options.

Water Level Controller Guide

You know how easy it is to forget about a water tank until something goes wrong if you’ve ever had to keep an eye on one. The tank might run low at times, which means the pump runs out of water. At other times, it fills up too much and the water goes to waste. A water level controller is meant to remove that stress off your hands by maintaining the water at the proper level on its own.

The idea behind these systems is simple, yet they may make a major impact in how well a water system works.

What Is a Water Level Controller?

A water level controller keeps an eye on how much water is in a tank and operates a pump depending on that level. The controller automatically turns the pump on and off, so someone doesn’t have to handle it by hand.

The pump turns on when the water level goes below a certain threshold. The controller turns off the pump when the tank is full and reaches the top. It’s a simple operation, but it prevents a lot of the difficulties that come up when people handle tanks by hand.

How Controllers for Water Levels Work

Most controllers use sensors that are put in different places inside the tank. The system knows whether the water level is too low or too high because of these sensors.

Some systems use float switches that move up and down with the water. Some people utilize electrical probes or sensors to find out how deep the water is. The approach may change, but the aim is always the same: to maintain the water level consistent without having to watch it all the time.

Once the controller is set up and installed, it works silently in the background and doesn’t need any maintenance.

Why It’s Important to Control the Water Level

It’s easy to forget how much stress bad water level control may create on a system. Pumps that run too much or run out of water wear down more quickly. Tanks that are over full might waste water and even harm the region surrounding the tank.

A water level controller can help keep these things from happening. It preserves equipment, saves water, and cuts down on the need for regular monitoring by keeping the system functioning within the correct parameters.

The best thing for many homeowners and facility managers is just peace of mind.

Where to Use Water Level Controllers

More sites than most people know employ water level controls. People who live in homes with storage tanks depend on them to keep the water flowing. They help farms and irrigation systems use water more effectively. They are typically used to keep cooling systems and process tanks running smoothly in commercial buildings and factories.

It is crucial to keep the proper level of water in any place where it is kept or pumped, and automation makes that much easier.

How to Pick the Right Water Level Controller

Not all systems are the same, so the size of the tank, the type of pump, and the place where everything is set up will determine which controller is best. Some installations demand highly fine control, while others merely need a simple, dependable system.

Talking to someone who works with these systems on a daily basis might help you avoid making mistakes and pick equipment that will last.

How To Install A Water Level Indicator

Installing a water level indicator can be a straightforward DIY project or a more technical job, depending on the type of system (mechanical, float-based, sensor-based, or electronic). Below is a general step-by-step guide for installing a basic electronic water level indicator system for a standard overhead tank.

🧰 What You’ll Need:

Water level indicator kit (includes sensors, control unit, wires, and possibly a display)
Power drill
Waterproof silicone or sealant
Electrical tape
Screwdriver
Cable clips or zip ties
Ladder (if the tank is elevated)

🪜 Step-by-Step Installation Guide

✅ 1. Turn Off Power

Always start by turning off the main power supply if you’re working with electrical devices.

✅ 2. Mount the Control Unit

Choose a dry, accessible location near the tank or inside your house (depending on the model).
Mount the control/display unit on a wall using screws.

✅ 3. Install Sensor Probes in the Tank

You typically need 3 to 5 probes (depending on your system), which measure:

Empty/Low level
Middle level
Full/High level
(Optional) Overflow or critical low

How to install:

Drill small holes on the tank lid or side wall near the top.
Insert the probes or float sensors to the corresponding depths (use the manual to know the exact position).
Seal around the holes using waterproof silicone to prevent leakage.
Secure the sensor wires with cable clips inside or along the tank body.

✅ 4. Connect Wires to the Control Unit

Use the labeled diagram in your kit’s manual to match each sensor wire to its terminal.
Typically, wires run from each sensor to a central controller unit via color-coded terminals (e.g., red = full, yellow = mid, green = low).
Use electrical tape to secure connections and prevent short-circuits.

✅ 5. Test the System

Turn the power back on.
Slowly fill the tank and monitor the display or indicator lights.
The control unit should light up or beep as water reaches each sensor level.

✅ 6. Optional: Connect to Pump

If your indicator supports pump automation:

Connect the pump’s power relay to the controller as instructed.
The system will automatically turn the pump on when water is low and off when full.

🔒 Safety Tips:

Always use waterproof-rated wires and connectors.
Keep control units protected from rain and moisture.
Don’t overtighten sensors; water tanks expand slightly when filled.

🛠️ Types of Systems You Can Install:

Type	Difficulty	Features
Float-based	Easy	No electricity needed; mechanical
Electrode/probe	Moderate	Common in homes; needs wiring
Ultrasonic sensor	Moderate	No contact with water; more accurate
Smart IoT systems	Hard	Remote monitoring via smartphone

History of Water Level Sensors

Water level sensors have a long history dating back to ancient times when simple devices were used to measure water levels for irrigation and flood control. Over the centuries, advancements in technology have led to the development of more sophisticated water level sensing devices for various applications. Here’s a brief overview of the history of water level sensors:

Ancient Water Level Measurement: The earliest water level measurement devices were simple float-based mechanisms used by ancient civilizations for irrigation and flood control. These devices typically consisted of a float attached to a lever or rod, which would rise and fall with the water level, indicating the depth.
Early Mechanical Water Level Gauges: In the 17th and 18th centuries, mechanical water level gauges were developed for use in wells, reservoirs, and other water storage systems. These gauges often used a float connected to a chain or pulley system to measure the water level.
Development of Electrical Sensors: The invention of electrical conductivity and capacitance sensors in the 19th century paved the way for more accurate and reliable water level measurement devices. These sensors could detect changes in water level by measuring changes in electrical properties such as conductivity or capacitance.
Ultrasonic and Radar Sensors: In the mid-20th century, ultrasonic and radar-based water level sensors were developed, offering non-contact measurement capabilities. These sensors emit sound or radio waves that bounce off the water surface and are then detected to determine the water level.
Pressure Transducers: Pressure transducers, which measure water level based on the pressure exerted by the water column, were also developed in the 20th century. These sensors are commonly used in applications such as groundwater monitoring, sewage systems, and industrial tanks.
Modern Sensor Technologies: In recent decades, advancements in microelectronics and sensor technologies have led to the development of highly accurate and versatile water level sensors. These sensors often use a combination of different measurement principles, such as ultrasonic, pressure, capacitance, or optical sensing, to provide precise and reliable water level measurements in various environments.
Wireless and IoT Integration: With the rise of wireless communication and Internet of Things (IoT) technologies, water level sensors can now be easily integrated into remote monitoring and control systems. These systems allow for real-time monitoring of water levels and automated alerts or actions based on predefined thresholds.

Today, water level sensors are widely used in various applications, including environmental monitoring, flood warning systems, water resource management, wastewater treatment, agriculture, aquaculture, and industrial process control. Continued advancements in sensor technology are expected to further enhance the accuracy, reliability, and functionality of water level sensing devices in the future.

Types of Pumping Stations

A pump station is a product used to lift or move water when no gravity fall can be achieved. Installed underground and often cylindrical in shape, the pump station would normally have 1 or 2 pumps installed inside it. Float switches monitor the level of water in the tank. As water enters the tank and fills up, the float switch activates the pump to move the water to its desired location.

Different types of pump station

There are different types of pump stations depending on the application and water it is receiving as follows:

Crude pump stations

A crude pump station (or sometimes called a raw sewage pump station) is designed to move wastewater from a building. The pumps will normally be vortex pumps with a large free passage to enable solids to be moved, or grinder pumps which churn up solids to allow pumping through narrower pipes.

Final effluent pump stations

A final effluent pump station is designed to be used to move treated water (containing no solids). These are commonly used when the outlet of a treatment plant needs to be lifted. The pump station can be fitted with single or twin pumps. Alarm options are also available.

Surface water pump stations

A surface water pump station works in the same principle as all pump stations, it takes water from surfaces (roofs, or groundwater) and used in the event no gravity fall can be achieved. The pump(s) will be sized depending on the estimated flow rate and the distance the pump has to move the water.

Adoptable vs Private Pumping Stations

Broadly speaking, pumping stations can be divided into two main categories – Adoptable Pumping Stations and Package Pumping Stations.

Adoptable Pumping Stations are designed for large-scale applications and comply with all Water Company requirements, Sewers for Adoption specifications and the DCG (Design Construction Guide), making them suitable for use on public land.

Package or Private Pumping Stations are used for removing wastewater from privately run developments, whether residential or commercial properties.

Sometimes ownership of pumping stations is transferred, via a legal process known as pumping station adoption. For example, legal ownership in a housing development might be transferred from the developer to the local water authority. They would then be responsible for the ongoing maintenance of the pumping station.

Pumping Stations
