Understanding Plano’s Outdoor Mandatory Watering Restrictions


Posted: June 20, 2006

The City of Plano is initiating mandatory once-weekly outdoor watering restrictions effective June 19, 2006. This is the second in a three-part consecutive series explaining those restrictions and providing information on your watering day and related outdoor watering information.

It’s Quick…it’s easy! Locate your watering day on the zone map. Remember your watering hours. Continue to enjoy a healthy landscape.

Let’s find your watering day! Check the zone map below for your location and water day, which runs for the 24-hour period from 12:00am to 11:59pm.



You can water anytime on your watering day except during the daylight hours between 9:00am – 6:59pm, when water is most likely to evaporate from the heat of the sun.
Once weekly watering will maintain a healthy lawn. In fact, experts say it promotes the strong root system a Texas lawn needs to flourish. Raising your lawn mower to a 3” mowing height can also give your yard a boost by providing an extra inch or two of “shade” for the growing underlying turf.

While grass can flourish with weekly watering we realize certain flowering plants and shrubs cannot. You are allowed to hand-water your potted plants and landscape beds on any day, except between the hours of 9:00am – 6:59pm. You must use a hand-held hose that is equipped with a shut off nozzle. You cannot leave the hose running unattended.

We encourage you to delay new landscaping at this time, but if you are installing new plants, consult your plant supplier about the use of drought tolerant plants. They are attractive, hearty and thrive in the hot Texas sun! Use mulch in your landscape beds to decrease water evaporation and provide root protection.

Excessive water run-off is prohibited. This is when water runs for more than ten feet off your property onto adjacent properties, normally pooling onto concrete areas, such as streets, sidewalks, etc. Water run-off is a sign you are over-watering your landscape.

What about filling your swimming pool or spa? Water used in maintaining swimming pools is drastically less than that used in landscape irrigation. You can maintain your swimming pool at its proper operational levels, but if water levels fall more than usual check for leaks. The construction of new pools or spa installations is not prohibited and draining and filling a pool for repairs is also authorized. Filling a pond or lake with potable water is prohibited.

How about your foundation? Our Texas soil does make it tricky in the dry summer months for some foundations, which may crack when the soil around them separates. You are allowed to water your foundation, if needed, using a soaker hose (a hose with small holes in it that allows water to seep slowly out and absorb into the soil.) Again, avoid the hours between 9:00am – 6:59pm.

Can you wash your vehicle or the family dog? Certainly! We encourage the use of commercial car washes for your vehicle, as they recycle their water and conserve our resources, but if you prefer your home, try washing from a bucket then hosing off your vehicle. Be sure your hose is equipped with a shut-off nozzle to prevent waste and watch for excessive water run-off.

Plano will begin enforcement of its water restrictions on June 19, 2006, with criminal penalties imposed for violation of the City’s Drought Contingency Plan, Ordinance 2006-5-23, including terminating irrigation water service for multiple violations. Keep in mind that a power surge or a power failure can cause your automatic sprinkler system to return to its default settings. Regularly check and change your controller batteries. Learn how your automatic sprinkler system works and ensure you have a back-up person who can also operate the system in the event you are away and a reset is needed.
