Schertz receives its water from the Carrizo Aquifer, not through the Edwards Aquifer Authority. The Carrizo Aquifer is not under Stage 1, 2, 3, or 4 restrictions. Schertz promotes a year-round water conservation plan, the rules are as follows:

  • Year round outdoor sprinkler watering is prohibited between 10 a.m. to 8 p.m. daily. The use of a handheld hose or other handheld watering device or a drip irrigation system can be used at any time.
  • It shall be a violation if a person or customer allows water to run off into a non-pervious ditch, or fails to repair a controllable leak.
  • Re-use water usage is exempt from the water conservation plan.
  • Customers using water from a private water well must comply with all requirements of the water conservation plan.
  • All persons are urged not to waste water.
  • As this dry season continues, be prepared for restrictions to be placed. Be water-wise.


The City of Schertz Water Department is regulated by the Texas Commission on Environmental Quality (TCEQ). The TCEQ rules state “the system must be designed to maintain a minimum pressure of 35 psi at all points within the distribution network at flow rates of at least 1.5 gallons per minute per connection.”

The deviation in elevation throughout Schertz’s water service area makes it impossible to maintain one constant pressure zone for our customers. Higher elevations will tend to have lower water pressures and lower elevations toward higher pressures. The Schertz water system is designed to provide a minimum of 750 gpm fire hydrant flow and insuring that we meet the minimum water pressure requirements. It is important to know that the Texas/Schertz plumbing/building code requires a pressure reducing valve to be installed when water pressures at the residence exceeds 80 psi. Although the working pressures of house plumbing and appliances exceed 80psi, some insurance companies will not cover any damages or replacement of an appliance if this situation exists. It is important for you to know what your insurance provider requires/will cover. If you have any questions concerning the water pressures in Schertz, contact the Schertz Water Department at 210-619-1800. To find out what your insurance companies rules are about coverage to damage to, or replacement of an appliance, you should contact them directly.
