Construction activity along with heavy rains caused a 24-inch pipe to collapse in a recently excavated and backfilled hole at the Stewart Creek Waste Water Treatment Plant.
Crews noticed the leak at 8:30 a.m. Monday, Feb. 26, and began excavation immediately. Repairs were completed by 1 p.m. the same day.
The leak resulted in an unauthorized discharge of 54,000 gallons of partially treated wastewater combined with stormwater runoff into a storm drain on the east side of the plant that leads directly into Stewart Creek and Lewisville Lake.
This event does not impact The Colony’s potable water supply system; drinking water delivered by the City of The Colony is safe for human consumption. Environmental assessments are underway, and any detectable downstream environmental impacts will be treated in accordance with all applicable laws and regulations.
The public should avoid contact with waste material, soil or water in the area potentially affected by the spill. If you have any questions or concerns, please contact Public Works at 972-624-3129.
