Water Supply Frequently Asked Questions

What is the GRP and how will it affect me?

Information on the Groundwater Reduction Program can be found by visiting the GRP Divisions website.

Where does the drinking water come from?

Prior to October 2015, the MUDs located within The Woodlands received 100% of the water supply from groundwater wells spread out in The Woodlands area.  In October 2015, the groundwater supply was supplemented with surface water from Lake Conroe through the SJRA GRP Division.

What is groundwater?

It is the water located underground that fills the voids, cracks, and other openings in the various layers of rocks, sand, and soil. It is found in formations that are able to retain it and is constantly replenished by rain or snow. In most cases, groundwater is naturally filtered by the layers of sand it percolates through as it moves through the aquifer underground.

What is an aquifer?

An underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, silt, or clay) from which groundwater can be pumped using a well.

How is groundwater treated?

The groundwater located in The Woodlands area is treated by chlorine disinfection only.

Is my water safe to drink?

Yes. The Woodlands water meets or is better than all standards set by the state and federal governments. The State of Texas has assigned “Superior” ratings to The Woodlands MUD’s, the highest rating given by the state.

Why is it important to protect and conserve water?

Water supplies are strained by growing populations and increasing demand. Each year, Texans spend more than one billion dollars on new or expanded water supply and wastewater treatment facilities. Water conservation not only saves money on your monthly water bill, it also minimizes future water problems and costs.

We have a reliable water supply, why should I conserve?

There are lots of good reasons to conserve water. Here are just ten reasons:

  1. Water is a scarce natural resource –  97% of water on earth is saltwater and 3% of it is fresh water.  Of that 3%, less than 1% is fit for human consumption
  2. Save on water bills
  3. Save energy on less water heating
  4. Save on sewer (wastewater) bills
  5. Avoid possible water restrictions
  6. Reduce possible polluted yard runoff from irrigation usage
  7. Reduce future expansion of water facilities
  8. Reduce the load on wastewater treatment plants, delaying the need for expansion
  9. Be environmentally friendly
  10. What is the average water use for The Woodlands in a month?

Water production fluctuates on a monthly, even daily, basis. For more information, click here

SJRA receives no money from the state, nor does it collect any type of taxes. Income is primarily derived from the sale and distribution of water and treatment of wastewater. This revenue covers the cost of operation and maintenance as well as outstanding debt. Revenue bonds are sold to finance projects.
