Water Quality
Regulations
The City of Sugar Land serves drinking water that meets all EPA and Texas Commission on Environmental Quality regulation requirements.The City operates three independent water systems that serve the Riverpark, Greatwood, and New Territory neighborhoods and the Main system that serves the rest of Sugar Land. The analysis for the Water Quality Reports are made by using the data from the most recent EPA-required tests and is presented in the following downloadable documents. We hope this information helps you become more knowledgeable about our drinking water. Printed copies of the Water Quality Report can be requested from the Public Works Department 281-275-2900.
Important Information About Your Drinking Water
The City of Sugar Land’s water systems are participating in gathering data under the EPA’s Fifth Unregulated Contaminant Monitoring Rule (UCMR5). Unregulated contaminants are those that don’t yet have a drinking water standard set by EPA. The purpose of monitoring for these contaminants is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted. As our customers, you have a right to know that these data are available. UCMR results and occurrence data can be viewed by the public at https://www.epa.gov/dwucmr/occurrence-data-unregulated-contaminant-monitoring-rule.

Under UCMR5, public water systems nationwide will be monitoring for 29 per- and polyfluoroalkyl substances (PFAS) and lithium in drinking water. During 2023, the city will be monitoring for these compounds in the drinking water served by our Main, River Park, Greatwood, and New Territory water systems.

Water Hardness
The primary minerals in drinking water that cause hard water deposits are calcium and magnesium. The City currently uses well water which can vary in water hardness from well to well. The City’s Main Water System also uses surface water from Oyster Creek and the Brazos River. This treated surface water is blended with the groundwater before being distributed to customers. Therefore, it is best to consider the system as a whole and to look at the hardness as a range in order to capture the full potential:
Sugar Land's Water Hardness Levels
| Water System |
Parts per million (ppm) |
Grains per gallon (gpg) |
|---|---|---|
| Greatwood | 34 to 164 |
2.0 to 9.6 |
| Main | 35 to 280 |
2.0 to 16.4 |
| New Territory |
50 to 186 |
2.9 to 10.9 |
| River Park |
109 to 155 |
6.4 to 9.1 |
Typical Hardness Ranges
- Soft: 0 to 17 ppm / 0 to 1 gpg
- Slightly hard: 17.1 to 60 ppm / 1 to 3.5 gpg
- Moderately hard: 61 to 120 ppm / 3.5 to 7 gpg
- Hard: 121 to 180 ppm / 7 to 10.5 gpg
- Very Hard: more than 180 / more than 10.5 gpg
Water Softener
Customers may contemplate getting softener based on their desired aesthetic qualities of water. Hard water can cause crusty white to off-white build up around faucets, shower heads, toilet bowls, and sinks. This deposit can be removed with products designed for this function that can be purchased at local stores.
