Water & Sewer
Water is pumped into the city's distribution system and stored in elevated and ground storage tanks. The City has a combined ground storage space equal to 24 million gallons and 9 million gallons in the elevated water towers. Together, that provides 33 million gallons of storage space.
Sewer Services oversees the collection of all wastewater and its transmission to the wastewater treatment plants. The City of Allen contracts with NTMWD to treat all wastewater generated in the City. This service includes the operation, maintenance and repair of all sewer lines, manholes and lift stations connected to the wastewater collection system.
Beginning Nov. 1, 2017 Allen water and wastewater rates will increase.
The City of Allen purchases water and wastewater services from the North Texas Municipal Water District and then delivers it to Allen residents. Even though NTMWD has increased its rate for purchase over the last few years, Allen has not passed the cost onto Allen residents since Feb. 2015. This year, the NTMWD has projected a rate increase of about 10% per year for the next five years. This NTMWD rate increase will cause residents to see an increase in their monthly bill. Beginning Nov. 1, a customer using an average of 10,000 gallons per month will see an $8.18/month increase in their utility bill for water and wastewater services. Allen residents will continue to pay a lower rate than neighbors in Frisco, McKinney, Plano and Richardson, and the rate will still be significantly lower than the state average.
