From April 1st – October 31st, spray irrigation is limited to once a day up to twice a week, on any day(s) you choose. Running spray irrigation once a week and hand watering elsewhere as needed is usually sufficient.

Spray irrigation controllers should not be set to run after 10 AM or before 6 PM, recommended 3-7 minutes for run times per zone. Spray irrigation CANNOT run during rain and doing so violates the City of Princeton’s Water Conservation Plan which may result in a fine. Spray irrigation CANNOT be evident in water-waste (including excessive draining into nearby storm drains, sidewalks, streets, or other impervious surfaces), and doing so violates the City of Princeton’s Water Conservation Plan which may result in a fine.

We recommend using a rain sensor and downloading MyWaterAdvisor2 to track your usage to help prevent fees.

Water Conservation is the practice of utilizing water efficiently to reduce unnecessary water usage. The City of Princeton has a Water Conservation Plan in place.

Did You Know?

About 72% of the Earth is water, but only less than 2% of that is fresh water accessible by man.

Most high-water bills are from improperly set irrigation systems followed by undetected water leaks. That's ultimately wasted water.

Check out the Water Efficient Irrigation page to see how you can draw back on your water usage through your irrigation and get in-line with city code and ordinances.

Check your toilets for leaks! They can run silently – right under your nose. Come by the Public Works building at 255 E Monte Carlo Boulevard if you suspect your toilet may be leaking for free water smart information and toilet tabs, which when placed in your tank, can assist you in detecting water leaks from your toiletry. Do Your Part.

Water is the most important resource to sustain life and as the Earth's population grows, the need for water grows. Water is being used and wasted faster than it can be replenished.

  • Conserve water where you can.
  • Contribute to clean-up efforts to keep our local watershed clean along Tickey Creek.
  • Check your home regularly for leaks.
  • Plant like you live here. Plant native!

MyWaterAdvisor2, available on both iOS and Android devices, can assist residents in detecting water leaks at their property. Please download this app to view your real-time water usage and receive updates and alerts on your water usage.

WaterMyYard, available on both iOS and Android devices, will correlate your irrigation system with the local weather to let you know how much water your yard needs to stay healthy.

By conserving water, you not only do your part in Keeping Princeton Beautiful and in helping the planet – you could lower your water bill

There are tools for that.

  • A moisture meter can assist in preventing underwatering or overwatering of plants. This device measures humidity in the soil.
  • Low-flow devices installed in your home can assist in water conservation efforts.
  • A rain sensor is a device that can assist you in conserving water, as the name suggests, this device will detect when it is raining and switch your irrigation off.
  • A rain barrel can be purchased or made by hand and is effective in catching stormwater runoff from roofs. This device is only consistently effective if utilized regularly. Consider connecting this device to a drip system in the ground so it will regularly empty itself and be less likely to overflow.

A few things to keep in mind about water:

  • Water is old. The water we drink, water from rain, water in our bodies right now, is thousands of years old and regularly recycled.
  • Water should be conserved at all costs. There is no greater expense than being without water.
  • We live in a Watershed. All landscapes are in watersheds, event desert spaces. The watershed most local to us here in Princeton is that of Tickey Creek to Lavon Lake, meaning what we do on our land here impacts our drinking water.
