Friendswood Watering Rules

Friendswood adopted Ordinance No. 2024-14, a drought contingency plan with three stages (City Code). A City Water Conservation Plan took effect May 1, 2025. For tips and current notices, see the City’s water conservation page (City of Friendswood). Check the current stage before you set your watering days.

Soil and Climate

Much of the Houston area is coastal prairie clay. One common example is Lake Charles clay, whose official type location is in Fort Bend County. It is very deep and very slowly permeable, and in dry spells it cracks up to 2 inches wide and a foot or more deep (USDA-NRCS soil description). For a sprinkler system, that means water soaks in slowly, so long cycles run off or pool. The ground also shrinks and swells around buried pipe and fittings, and wet spots can stay wet long after watering, which makes a slow leak harder to spot. To see what’s under your own yard, look up your address in the USDA Web Soil Survey.

This area is in USDA hardiness zone 9b, where the coldest night of a typical year reaches 25–30°F (USDA Plant Hardiness Zone Map). Freezes are rare, but they happen. During the February 2021 winter storm, the City of Houston fell to 13°F, and the National Weather Service reported broken pipes across the region (NWS Houston/Galveston). Backflow preventers and exposed pipe above ground are the sprinkler parts most likely to crack. If yours sprays or drips after a freeze, see backflow preventer leaking.

Problems Friendswood Conditions Make More Likely

Backflow preventer leaks after a freeze

Hiring Someone in Texas

Texas licenses landscape irrigators at the state level. Under Texas Occupations Code Chapter 1903, anyone who installs, repairs or services an irrigation system for pay generally needs a state irrigator license, or must work under a licensed irrigator. A homeowner working on their own property is exempt. Ask any contractor for their license number and check it with the state (license information).

Texas rules also require backflow protection on irrigation systems connected to drinking water (30 TAC 344.50). If your backflow device is leaking or was damaged, have a licensed professional repair it rather than taking it apart yourself.
