Water & Sewer

The Water and Sewer Division is responsible for delivering potable water purchased from the North Texas Municipal Water District (NTMWD). The City of Allen’s Water and Sewer Operations are responsible for operating, maintaining and repairing water lines, valves, fire hydrants, sewer lines and manholes. This division also provides field assistance to customers, inspectors and contractors. These operations are housed at the Stacy Road Pump Station.

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.

Annual Water and Wastewater Rate Changes

The City of Allen and NTMWD perform cost projections and rate studies to determine how much money they will spend to deliver safe, reliable drinking water to each of their customers. In 2017, NTMWD informed member cities that a rate increase of about 10% per year for the next five years was needed to develop new water supply sources, replace aging infrastructure, and enhance new technologies to further safeguard public health. For this reason, a customer rate increase was needed and implemented Nov. 1, 2017. The increase in combined water and wastewater charges was approximately $8.18 per month for a residential customer using an average of 10,000 gallons of water per month.

In 2018, NTMWD announced that budgeting changes would result in a lower wholesale water rate increase to member cities than initially announced. Those savings will be passed on to Allen utility customers by lowering the expected 10% annual water rate increase to 7%. This increase in combined water and wastewater charges will be approximately $7.70 per month for a residential customer using an average of 10,000 gallons of water per month. Residents will see the new rate reflected in their November 2018 utility bills.

Allen City Council previously directed actions that help reduce water costs. In 2017, council members voted to raise infrastructure impact fees for new developments and changed the way water and sewer infrastructure projects were financed, saving customers $15.75 million over the next 10 years. Even with the most recent increase, most Allen customers continue to pay a lower rate than neighbors in every NTMWD member city, including Frisco, McKinney, Plano and Richardson. Allen's rate is also significantly lower than the state average.
