About Your Water Service

Exeter water tower
Water Sources

The city’s water system which consists of eight wells, chlorination treatment facilities at each of the active wells, two inactive wells, one elevated storage tank with a capacity of 100,000 gallons, and a loop distribution system.

The City of Exeter utilizes a ground water system.  No surface water is used by the water system.  Water is pumped from 6 active deep wells ranging in depth from 296 to 620 feet.

Water System

Water is delivered to our homes and businesses through underground supply lines that are laid out in a grid-like manner so that there are no dead ends of major mains.  This process is also known as looping.  The existing distribution piping ranges from 6″ to 12″ in diameter.  In 2004 the city replaced most of its old cast iron pipe water mains with C-900 polyvinyl chloride (PVC) pipes.  The distribution system is within one pressure zone ranging between 40 and 60 psi.  There are roughly 2,988 residential, 269 commercial and 19 industrial service connections which are all metered.

The system is capable of producing and delivering approximately 6.6 million gallons of water per day.

Answers to Your Questions

What about sand in my water?

Sand and debris, which may appear in your faucet’s aerator screen, are most often caused by mineral deposits in your household system, plumbing repairs, or sand produced by wells.  There are no health impacts associated with this debris, but it can be a nuisance.  A persistent sand or debris problem should be reported to the water division.

What causes low water pressure?

Low water pressure can be caused by either a home’s gate valve not being fully opened, recent repairs to existing plumbing, or too great a demand for the available water supply.  The city’s water pumping systems are electronically controlled though a computerized management system to operate between 40 and 60 psi.

Is our water chlorinated?

Yes, there are chlorination treatment facilities at each of the active wells.  The chlorine is used to control bacteria.

Why is my water sometimes cloudy?

Cloudy or milky water at the tap is caused by air in the water.  When this occurs, let the water settle in a glass or pitcher for 10 to 20 seconds.

Water Quality

In order to insure good clean water in all areas of the system, water division personnel will be flushing water lines at various times.  Employees will request that young children not play in the water for safety reasons.  If you have a problem or complaint regarding water quality, please call the Public Works Office at 559.592.3318; Monday through Friday 7:00 a.m. to 3:30 p.m.  For after hours emergencies, please call 559.592.3710.
