Smart Watering Tips

How Much, When, and How to Water...

BV WaterSmart logo Lawn water needs can vary based on rates of evaporation, rainfall, sun exposure, and wind. The Brazos Valley WaterSmart network uses data from a network of weather stations and rain gauges to provide customized water-saving recommendations.

Get to know your sprinkler system:
Sprinkler heads have varying precipitation rates depending on their design. The most efficient sprinkler heads have lower precipitation rates that allow the soil to soak up irrigation water without runoff. Typical sprinkler precipitation rates: Multi-stream rotors - 0.3 inches per hour; rotor heads - 0.5 to 0.75 inches per hour; fixed sprays - 1.25 to 1.5 inches per hour. Watering requirements are typically given in inches of water, so it's important to know your sprinkler's precipitation rate so you can translate inches of water needed into minutes of run time. Click here to view watering recommendations for College Station. Use this simple formula below to determine how much water your sprinkler applies in a given time period:

• Set 3 to 5 empty shallow flat-bottomed cans at different distances from the sprinkler, with the last can near the edge of sprinkler coverage.
• Run the sprinkler for 10 minutes.
• Add the inches of water in all cans and divide the total inches by the number of cans to obtain an average.
• Multiply the average by 6. This is your sprinkler's precipitation rate in inches per hour.

Just 2 Days per Week
In order to conserve water, College Station encourages customers to water outdoors no more than TWO days per week. The schedule outlined below is voluntary (unless the City is in a Stage 1 or Stage 2 Drought) and provided as a guideline. Start with one watering day per week, and then add up to one additional watering day only when needed later in the summer.

Practice Cycle & Soak
For soil with poor drainage, divide long run times into several shorter cycles on the same day. This is what is known as "cycle and soak." For example, instead of running the sprinkler for 30 minutes continuously, water for 10 minutes, 3 times, with each watering time separated by an hour or more. This will give your grass a deep soaking every time you water.

• Do NOT water outdoors with an automatic in-ground or hose-end sprinkler systems between 10 a.m. and 6 p.m.
• DO set sprinklers to irrigate before 10:00 a.m. or after 6:00 p.m.
• Do NOT operate an irrigation system with sprinkler heads that are broken or out of adjustment.
• Do NOT allow water to run off a property or allow water to pool in a street or parking lot.
• DO repair controllable leaks within a reasonable time period after notice has been given to repair the leak.
