City Water Quality & Services Provided
All potable water originates from the natural water cycle. Nassau Bay receives its potable water supply from the City of Houston. Nassau Bay contractually owns a portion of the water treatment capacity of the City of Houston’s Southeast Water Purification Plant.
The City owns, operates, and is responsible for the complete water distribution system to the customer’s side of the water meter. The City owns all water lines, appurtenances, water meter, water meter box, and connections up to the connection to the private water line on the customer side of the water meter.
Nassau Bay, as water purveyor, is responsible for the quality of water supplied to the farthest tap on private property. This responsibility includes the authority to inspect and enforce water quality protection requirements of all water users on their private property. This City responsibility does not relieve water customers of their responsibilities for assuring that their water distribution system on their private property complies with all applicable regulatory and plumbing codes.
Nassau Bay municipal water supply operation and maintenance is regulated by the U.S. Environmental Protection Agency (EPA), Texas Commission on Environmental Quality (TCEQ), Texas Water Development Board (TWDB), and City ordinances. Compliance with these regulatory requirements provides comprehensive guidelines which assure the residents of Nassau Bay an adequate supply of quality water.
By State law, Nassau Bay must charge fees for all water supplied to users from the City’s water system. By State law, these fees must cover:
- All costs of capital improvements and renewal / replacement of water infrastructure assets
- All costs of operation and maintenance of the City’s water system
- The costs of obtaining and supplying adequately treated water at adequate pressures
These include the total cost to procure and install all necessary lines, connections, water meters, water meter boxes, curb stops (valves), and all other appurtenances necessary to provide a point of connection to a customer private water line.
All water and sewer fees established and charged by the City of Nassau Bay must be approved by the TCEQ, TWDB, and Nassau Bay City Council.
Water Quality Regulatory Compliance
The Nassau Bay water and wastewater systems are subject to the applicable regulatory requirements of the Texas Commission on Environmental Quality (TCEQ), Texas Water Development Board (TWDB), and the United States Environmental Protection Agency (USEPA). In Texas, the TCEQ and TWDB have primacy for administering wastewater and water regulatory requirements as formulated by the EPA.
The intent of the applicable regulatory requirements is to assure that the City of Nassau Bay manages its water and wastewater systems to protect human health and the environment. The City of Nassau Bay has established a collaborative relationship with the TCEQ and TWDB which reinforces the City’s commitment to providing its residents with quality water services.
The applicable regulatory requirements are codified in Texas Administrative Code (TAC), Title 30 - Environmental Quality, Part 1 - Texas Commission on Environmental Quality. The City of Nassau Bay has also adopted City Ordinances as appropriate to assure administrative and system management compliance of the City’s water and wastewater systems with all applicable portions of TAC Title 30, Part 1.
Consumer Confidence Reports
As required in the Texas Administrative Code, Title 30, Part 1, Chapter 290, Subchapter H - Consumer Confidence Reports; the City of Nassau Bay provides an annual report which documents the compliance of the City in administering its water and wastewater systems to provide safe, quality water, and sewer services to its customers. This report provides specific information on the water quality criteria which are monitored by the City and by TCEQ.

Protecting Nassau Bay's Water
Quality water is an increasingly scarce resource. Protection of our water supply requires continuous effort to identify and eliminate, to the maximum extent possible, potential contamination of both raw water supply sources and potential contamination of treated water systems.
The City’s pertinent ordinances and the pertinent regulatory requirements provide detailed water system operation and maintenance guidelines which the Water Department administers to assure that our water is safe.
