Have You Registered Your Water Well?

Water well drilling.

If you live within the Trinity Glen Rose District boundaries and have a private groundwater well, you need to make sure that well is registered with the Trinity Glen Rose Groundwater Conservation District (TGR). Here’s why.

While Texas is a "right of capture state" meaning the state doesn't regulate groundwater like it does surface water, groundwater conservation districts (GCD) have been authorized by the State legislature to mange aquifer use in varying degrees and is the State’s preferred method of managing groundwater. In all cases, GCDs are responsible for knowing where the water wells in their districts are and how they are impacting the aquifers supplying the water. Additionally, there are regulations on how water wells are drilled and plugged in order to help prevent contamination from getting into the aquifer.

“We want to remind people living in the Trinity Glen Rose District that all water wells need to be registered with the district, including the wells that existed before district creation. It is our job to protect, preserve, and conserve the groundwater resources of the trinity aquifer in the district, and to decrease the effects of drawdown on neighboring wells,” said TGR Assistant General Manager Amanda Maloukis. “If your well is not registered with the district then we can't protect it and there are tens of thousands of people living in the district who benefit from a healthy Trinity Aquifer.”

2021 WaterSaver Landscape Tour Set for June 26
Watersaver Landscape Tour Graphic.png

The 2021 Watersaver Landscape Tour is scheduled for Saturday, June 26 at 10 a.m. This year’s tour will be held online as was the 2020 Tour. We are currently working with homeowners whose landscapes will be featured this year and given the recent plentiful rain, you can look forward to seeing some very colorful, extraordinarily beautiful yards that do not use a lot of water.

For each of the five featured homes, you will see a short video that contains an interview with the homeowner to get their perspectives on how they created their yards. Horticultural experts will be on hand to comment on the featured landscapes and answer any questions you might have about them. Viewers will also be able to download a plant list from each yard.

The 2021 Watersaver Landscape Tour will be brought to you by the Gardening Volunteers of South Texas (GVST), San Antonio Water System (SAWS) and Trinity Glen Rose Groundwater Conservation District (TGR).

To get a feel for how the Tour will run, check out last year’s featured landscapes at this link.

Time to Have your Sprinkler System Checked
$50 Coupon for irrigation consult v2-2.j

July through September is typically the hottest and driest stretch of weather we see in South Texas each year. Any by now you know that means that your water conservation knowledge and skills should be on high alert. Because landscape watering can account for up to 60 percent of the city’s water use during this time of year, the Trinity Glen Rose District always like to remind homeowners and business owners to have their sprinkler systems inspected before the systems are turned on for regular use. Wasted water cannot be retrieved, so you only get one chance to efficiently use the water provided by the city’s water resources such as the Trinity and Edwards Aquifers.

The quickest do-it-yourself way to check your system is to start it up and then inspect each of the sprinkler heads in all of the system’s zones. Look for broken heads or heads that have sunken below ground. Then make sure that the heads are not watering the streets and sidewalks. Then you can observe whether there is adequate water pressure feeding each sprinkler head. A broken pipe or sprinkler head can drain away pressure and waste significant amounts of water.

Also, if you have been slowly and steadily replacing high water use plants with native low water use plants, you might make sure that your sprinkler system either does not water areas with native plants or waters only a little.

Here is some great news for you. The Trinity Glen Rose District and San Antonio Water System have teamed up over the last few years to offer free irrigation system consultation programs. In fact, TGR will give you a $50 coupon to have the consultation done. Just go to for more information.

TGR Addressing COVID-19 Virus Health Safety Concerns

The Trinity Glen Rose Groundwater Conservation District (TGR) staff relocated to a new office in Helotes just before the March COVID-19 virus pandemic declarations by the State of Texas and City of San Antonio. 

As of July 6, District staff alternate days throughout the week to minimize risk to constituents, staff and the general public by reducing group interactions. In the event an in-person appointment is needed, we will make every effort to accommodate. We will conduct a temperature screening prior to entering the office and require that all individuals present wear a mask and maintain 6' social distancing at all times. We will continue to monitor public health reports and recommendations and will continue to make future decisions based on the guidance provided by public health officials.

If you need assistance, you may call the office at 210-698-1155 and leave a message or you may call 210-219–5555 to contact someone directly.

TGR Publishes 2020 Annual Report 

The Trinity Glen Rose Groundwater Conservation District (TGR) just published its 2020 Annual Report. The TGR board reviewed the report in early March and approved the document for publication at its March meeting.

The 2020 Annual Report provides good background on the:

  •  purpose of the district

  •  district goals

  •  current leadership

  •  well monitoring work

  •  financial position, and

  •  community outreach programs

This year, the District included two charts which outline TGR’s involvement in regional GMA-9 joint water planning efforts required by the State of Texas. The charts provide a 10-year history of water use in the region and how that compares to the region’s goals for water production from the Trinity Aquifer. Those goals are known as “desired future conditions.”
