Municipal Well and Pump

The Persian Empire once accessed groundwater using hand-dug shafts that covered miles of ground. Thankfully, today’s municipal well and pump systems are more sophisticated than that and are capable of reinforcing your region’s drought resistance. The more water sources you add to your infrastructure, the more impenetrable your supply becomes. Water wells allow you to do so without requiring a huge land investment. They can also improve your return on investment enormously.

Discovering your Well Location

Potable water resources require a different well source than grey water supply, so the first step to establishing a well is always a hydrogeological assessment. A specialist will assess water quality, chemical parameters, and the quantity of water required. Municipal wells need up to 4, 000 gallons of water a minute, but property ownership can limit the groundwater you can access because surface transportation is necessary. Chemical storage areas, streams, and sewer lines also need to be considered.

Well Design

Your municipal well and pump installation will generally require a test hole, which will give you in-depth information about water levels and confining beds. Your well design will assure you of a stable, lasting resource that can pump water efficiently without carrying sediments. Traditional wells have a sump and bottom plate, a screen, and pipe, all of which are intended to filter water at several points. If your well taps into more than one aquifer, testing will also be done on a range of screening areas.


A well screen will filter out much of the sand and gravel carried from your water source. A blank well casing will filter finer sediments. A well-designed well is an economical one because pump failures and the like will be rare occurrences.

Choosing an Efficient Pump

Poorly sized municipal well and pump systems consume a lot of energy relative to the volume of water they manage. They’ll also be prone to frequent breakdown. The flow and pressure rates required will determine your pump design. A municipal system requires extreme pressure and volume capacity, which varies depending on the distance it needs to cover. Ground elevation and the distance between your well and its delivery point determine the power you need from your pump. You need at least a bar of pressure for every 10 meters of your well’s depth unless your community is a small one. You also need enough depth to draw water during a drought, but every unit of elevation requires extra energy, so a fine balance will need to be achieved.

The total dynamic head of your pump must accommodate pipe length, water levels, and the distance that water needs to travel. The more intelligently you make your selections, the more your return on investment will soar.  Booster and dosing pumps are typically used for wastewater treatment, while engineered pump systems such as high-flow skids are preferred for water distribution. Submersible pumps are used when water needs to be pumped from beneath the water surface.

The Problem with Energy Efficiency

Water and wastewater infrastructure tends to use a lot of power, often taking up 25% of municipal power usage. Baseline energy costs must be managed, and wells use considerably less energy than surface sources because of their reduced filtration needs. Building a right-sized installation will bring down well point costs even further, making pre-installation assessment critical to your maintenance costs.

Municipal well and pump installations support water distribution efforts to cope with seasonal peaks and other anomalies. They support pressure management, too, giving your community a more holistic supply to overcome seasonal challenges.
