The District’s water system, is a shared system with Harris County Municipal Utility District No. 364 (MUD 364) and consists of three water wells, storage tanks, pumps, pressurization tanks, and miles of pipe to deliver the water to your homes. This system provides water to the residents of Coles Crossing (MUD’s 364,365), The Park at Arbordale (MUD 365), and Stillwater Village (MUD 364), as well as a few surround commercial properties.

The Sanitary Sewer system is a shared system with Harris County Municipal Utility Districts 365 (MUD 365) & 364 (MUD 364) and consists of lift stations, wastewater treatment plant, and miles of pipe to take wastewater from your home to the wastewater treatment plant. The Sanitary Sewer system only collects waste water from home and businesses, it does not collect rainfall runoff. Rainfall runoff is handled by the storm water system which drains to our retention pond and this Cypress Creek.

All the facilities have been equipped, or are in the process of being equipped, with backup power generators to ensure continuous water and sanitary sewer service to our customers.

Water and Sewer FAQs

What is the “RWA FEE” line item on my bill?

“RWA” is one of the acronyms used to refer to the North Harris County Regional Water Authority. The North Harris County Regional Water Authority is also often abbreviated with the acronym “NHCRWA” (the acronym you will find in the Water Authority’s own materials). When you see these different acronyms, they are both used to refer to the same water authority. The “RWA FEE” you see on your bill is a pass-through fee charged by the NHCRWA to a MUD based on the amount of groundwater pumped and/or the amount of surface water received from the NHCRWA. The fee charged to the MUDs within the boundaries of the NHCRWA is not optional. NHCRWA typically reviews its rate structure and pricing annually and publishes new rates, which can be found in various publications on the NHCRWA website, including in this Updated Pricing Policy linked here.

What is the North Harris County Regional Water Authority (NHCRWA)?

The North Harris County Regional Water Authority, sometimes referred to simply as the NHCRWA or the RWA, is the entity responsible for securing a long-term, reliable supply of wholesale drinking water in our area, designated as North Harris County. As part of this ongoing process, the NHCRWA is in the process of building additional infrastructure to bring surface water, mostly from Lake Houston, to many Municipal Utility Districts, or MUDs, in our area with the goal of converting from the use of ground water (wells) to surface water (lakes, reservoirs) in certain designated areas. More details on the North Harris County Regional Water Authority and its capital improvement projects and plans for conversion can be found on the NHCRWA website at www.nhcrwa.org.
