Landscape Irrigation

Irrigation Systems are becoming more prevalant with the growing number of connections within the District. 

Due to this fact this section is intended to educate customers on:

  • state regulations and district policies
  • backflow prevention assemblies and testing requirements
  • tips on watering effectively


TCEQ regulation

30 TAC 344.51 (d) If an irrigation system is designed or installed on a property that is served by an on-site sewage facility, as defined in Chapter 285 of this title (relating to On-Site Sewage Facilities), then:

(2) any connections using a private or public potable water source must be connected to the water source through a reduced pressure principle backflow prevention assembly.

District policy

If a property utilizes a septic, aerobic system, or sewer treatment plant for waste water management and also has an irrigation system instlalled on the same property.  Then a reduced pressure principle backflow prevention assembly must be installed at the connection point (point of use) for the irrigation system.

This is intended to protect both the customer and the District from possible contaminants.

Testing Requirements:

All testable backflow prevention assemblies must be tested upon installation and annually thereafter. The policy is to ensure the backflow assemblies throughout the district are functioning properly which helps in ensuring the public water supply stays free of both contaminants and pollutants.  The District utilizes Backflow Solutions Inc. (BSI) services for notification and backflow prevention assembly tester (BPAT) registration.
