The North Texas Municipal Water District (NTMWD) has experienced a spill of domestic wastewater from the Wilson Creek Regional Wastewater Treatment Plant (Wilson Creek WWTP) at 3020 Orr Road, Allen.
The sanitary sewer overflows began at approximately 1 a.m. Thursday and concluded at approximately 2:15 a.m. with an estimated volume of 317,214 gallons of sewage overflow. These overflows occurred due to the excessive rainfall received this week.
Denise Hickey, who works in Water Resource Programs and Public Education for the water district, said the district is required to issue a press release is the overflow exceeds 100,000 gallons.
The sanitary sewer overflows occurred at the headworks, primary clarifiers and filter backwash stages of treatment within the plant boundaries, about a half-mile from its confluence with Lavon Lake and traveled through the storm water system approximately 2,600 feet to the lake.
To clarify, none of the overflow stretched beyond the boundaries of the plant, according to Hickey. NTMWD personnel have initiated clean-up activities.
The sanitary sewer overflows did not impact the NTMWD potable water system; drinking water delivered by NTMWD is safe for human use and consumption. Environmental assessments are underway, and any detectable downstream environmental impacts will be treated in accordance with applicable laws and regulations.
NTMWD personnel have notified the appropriate local governmental officials and the TCEQ Regional Office of this event. By required state law, NTMWD is letting persons using private drinking water supply wells located within a half-mile of the spill site or within the potentially affected area know that they should use only water that has been distilled or boiled at a rolling boil for at least one minute for all personal uses including drinking, cooking, bathing, and tooth brushing.
Hickey said that just about all water customers in the area have gotten away from having private water wells in favor of potable systems.
Individuals with private water wells should have their well water tested and disinfected, if necessary, prior to discontinuing distillation or boiling. The water supplied by your local municipality, whether directly through your faucet or provided to a wholesale customer, is safe to drink and may be used for personal use.
The public should avoid contact with the waste material, soil, or water in the area potentially affected by the overflow. If the public comes into contact with waste material, soil, or water potentially affected by the overflow, they should bathe and wash clothes thoroughly as soon as possible.
