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.

Freeze Warnings and Hard Freeze Warnings Expected

The National Weather Service has advised that subfreezing temperatures are likely beginning Thursday night and into Friday morning following the passage of a strong cold front.

High temperatures could quite possibly remain below freezing throughout the day on Friday and not warm up above freezing until during the day on Saturday.

Steps for Winterizing your Home

  • Insulate pipes with insulation sleeves, wrapping or using slip-on foam pipe insulation. Do not leave any gaps without insulation as cold air can affect the pipe in these spaces.
  • Winterize your sprinkler system by turning the water off to your irrigation system and drain your backflow preventer.
  • Maintain a heating source inside the building to protect pipes against cold.
  • Open cabinets underneath faucets.
  • Exterior hose bibs are normally left unattended, disconnect hoses and insulate faucets with covers or blankets.
  • House Shut off valve: Know where your shut off valve is located in case of an emergency. Valve is usually on the side of the house near the garage. Some homes the valve is inside the garage wall.
  • If you choose to leave a faucet dripping, please only let the faucet drip slowly. NO STEADY STREAMS.
  • If traveling for the Holidays, it is recommended that you turn the water off at the street and drain all your plumbing.

  • Locate and insulate pipes most susceptible to freezing — typically those near outer walls, in crawl spaces, or in the attic.
  • Winterize your house lines and irrigation system. Open your cabinet doors under your sinks to provide warm air circulation.
  • Disconnect garden hoses and shut off and insulate outside pipes and faucets.
  • Make sure you and your family know how to shut off the water in case pipes burst.
