City Water Plant
The City's newest Water Treatment Plant uses a system called nanofiltration, which safely removes undesirable organics, salts, and contaminates that may have bad taste. During the filtration process, unwanted particles are collected for disposal. Learn about the groundwater treatment via nanofiltration process.
Studies show that bottled water contains more contaminates than water processed with nanofiltration. Nanofiltration is an advanced treatment method that can also reduce salt levels and eliminate contaminants that older methods can not treat. Tap water must also undergo stringent Food and Drug Administration (FDA) mandated testing. The FDA exempts bottled water companies from many of these tests according to the Natural Resources Defense Council, What’s On Tap.
Getting Water To the Plant
Only water from the Castle Hayne Aquifer is pumped to this Water Treatment Plant. Water is drawn through 24 inches lines from shallow wells. The plant can process up to 4 million gallons of water daily.

Incoming water is treated with an antiscalant, a safe chemical that protects filters from buildup. Water initially passes through filters that remove large particles from the water.
Computerized Control Room Station
The Water Treatment Plant uses a computerized monitoring system that allows the plant manager and staff to monitor and control the performance of water filtration during all stages of treatment.
Water is tested in the lab for quality control. Testing is conducted at all stages of treatment and filtration for evaluation of:
- Chlorine residuals
- Dissolved oxygen
- pH levels
Lab testing helps to determine the quality of the water coming into the plant from the Castle Hayne Aquifer and water that has been treated at the plant.
After the nanofiltration process is complete, water is treated with a bio scrubbing system ,which uses a safe chemical to eliminate any naturally occurring odors that remain. After odor removal, water is disinfected, conditioned, and the pH is adjusted. Thoroughly cleansed water is held in a 2 million gallon container before distribution.
Water Plant Open House
The City celebrated the opening of the Water Treatment Plant on August 3, 2011. Residents and business and community leaders were in attendance to see City Council and the mayor 'turn on the taps'.
