Understanding the Groundwater Reduction Plan (GRP) Mandate in Summerwood Community
Summerwood Community is mandated by the Harris-Galveston Subsidence District to have a Groundwater Reduction Plan (GRP). In order to accomplish the State mandated requirement, Harris County MUD 361 follows the City of Houston GRP to reduce the use of ground water by converting from well water to surface water. The costs associated with building and maintaining the surface water infrastructure are passed on to its customers through the GRP fee on the monthly water bill.

The Surface Water Supplied by the City of Houston is Safe to Drink
Recent Taste and Odor Inquiries Regarding Drinking Water
The recent changes in taste and odor of the treated surface water being delivered by the City of Houston to HC MUD 361 are believed to be the result of a spike in Geosmin and Methyl-Isoborneol (MIB) which are naturally occurring compounds found in Lake Houston. All recent test results have confirmed that the water being supplied by the City of Houston to Harris County MUD 361’s customers is indeed safe and meets all State and Federal drinking water requirements.
Harris County MUD 361 purchases treated surface water from the City of Houston’s Northeast Water Purification Plant (the “NEWPP”), the raw water source of which is the San Jacinto River and Lake Houston. Seasonal changes such as temperature and rainfall events can influence Geosmin and MIB levels in the water in Lake Houston. Seasonal changes in the lake can impart variations in taste and odor of the treated surface water. The City of Houston continuously monitors the incoming raw water and the finished water leaving the NEWPP to ensure its compliance with all applicable State and Federal drinking water standards.
Harris County MUD 361 is working with the City of Houston to mitigate the variations in taste and odor to the maximum extent possible. Proper disinfection levels are being monitored and maintained. Flushing, where appropriate, is being done to help alleviate the situation. Harris County MUD 361 continues to monitor, sample and test the water coming into our system and throughout our transmission and distribution system to ensure that the drinking water being delivered by the City of Houston is safe to drink.
Geosmin and MIB Information Sheet
Geosmin and Methyl-Isoborneol (MIB) are naturally occurring compounds that have a very strong, earthy-musty odors.(1) Geosmin and MIB can be detected by humans at very low levels.
The City of Houston routinely monitors Geosmin and MIB in the water supply. These compounds are usually present in drinking water, however not at noticeable levels.
Generally, Geosmin & MIB become a taste & odor issue for customers when levels are in the range of 20-30 nanograms (one millionth of a milligram) per liter, but some people who are particularly sensitive may notice it at levels above 10 ng/l (2). To put it in simpler terms that would equate to one cent in a billion dollars.
What are the Effects of Geosmin and MIB?
Geosmin and MIB produce a musty, earthy smell and taste in drinking water, however both compounds are not harmful at levels present in drinking water.(3)
What Causes Increased Levels of Geosmin and MIB?
Some kinds of algae and bacteria present in lake and river water naturally produce Geosmin and MIB. An increase in this production typically happens during summer into early fall when lake levels are low, rivers are flowing slowly and water temperatures are warm.
What Can be Done About Geosmin and MIB?
Geosmin and MIB cannot be removed from water using normal treatment processes available at the existing NEWPP. The City of Houston adds Powdered Activated Carbon at the NEWPP to help reduce the levels of Geosmin and MIB.
