Where Does Our Water Come From?

The Woodlands Division provides water through groundwater wells designed to produce water from the Evangeline and Jasper aquifers. Some of these wells have been producing water since 1973 and have drill depths as deep as 1,700 feet below ground level.

SJRA – Woodlands water system is comprised of:

  • Maximum groundwater pumpage capacity: 70 MGD
  • 6 Elevated Storage Tanks (ESTs/ETs): Total 5 million gallons capacity
  • 8 Ground Storage Tanks (GSTs): Total 15 million gallons capacity
  • 5 Groundwater Plants
  • 38 Active Water Wells
  • 121 miles of water distribution lines (12” and larger diameter) belong to SJRA
  • 309 miles of water distribution lines (under 12” diameter) belong to WJPA (Excluding MUD 386)

SJRA – Woodlands Division works with the following agencies to provide water to The Woodlands area:

Lone Star GCD

The Lone Star Groundwater Conservation District (LSGCD) helps Montgomery County meet its most critical water challenge – finding the water to support growth without continuing to “deficit-pump” the Gulf Coast Aquifer.

Woodlands Joint Powers Agency

Woodlands Water (WJPA) is the central management agency for the eleven Municipal Utility Districts (MUDs). The services they provide are water distribution, wastewater collection, storm drainage and tax collection services.

GRP Division

 

The Groundwater Reduction Plan Division is responsible for implementing a county-wide program that will meet the requirements of the LSGCD to substantially reduce future groundwater usage from the Gulf Coast Aquifer.

 

Water Supply Frequently Asked Questions

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

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.

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.

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.

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

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.

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.

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.

Chromium-6 Frequently Asked Questions

Chromium is an odorless and tasteless metallic element. Chromium is found naturally in rocks, plants, soil and volcanic dust, and animals. The most common forms of chromium that occur in natural waters are trivalent chromium (chromium-3) and hexavalent chromium (chromium-6). Chromium-3 is an essential dietary element. It is found in many vegetables, fruits, meats, grains, and yeast. Chromium6 occurs naturally in the environment from the erosion of natural chromium deposits. Chromium-6 can also be produced by certain industrial processes.

The Environmental Protection Agency (EPA) has never set a specific limit for chromium-6. Instead, the EPA has set a federal standard for total chromium in drinking water, which is 0.1 ppm (parts per million). The current standard is based on potential dermatological effects over many years, such as allergic dermatitis (skin reactions).

Water systems are required by the Texas Commission on Environmental Quality to routinely test for total chromium. The last set of total chromium tests were conducted in March and April of 2017. The results for both sets of tests showed that levels were below the detection limit of 0.01 ppm, meaning that the amount of total chromium was basically undetectable.

There are a number of water treatment units that are capable of removing chromium-6 from the water supply. http://www.ewg.org/research/ewgs-water-filter-buying-guide is a website that compares various filters and their capabilities.

The TCEQ has a website that contains all sample results for Texas water systems. The website can be found by searching “TCEQ Drinking Water Watch” or by visiting: https://www.tceq.texas.gov/drinkingwater
