Rain Sensors#
Benefits#

When installed correctly, rain sensors automatically shut off your automatic sprinkler system when it rains. When the sensor dries, the sprinkler controller resumes regular operation.
- Conserves water -- prevents watering during and after rain events (until sensor dries)
- Saves money
- Less watering means less water you have pay for on your utility bill
- A sensor reduces wear on the irrigation system because the system runs only when nature isn't doing the watering for you
- Helps protect rivers and other bodies of water by reducing runoff and deep percolation that can carry pollutants, such as oils and fertilizers, into storm drains and groundwater
Installation#

- A rain sensor should be mounted where it will be exposed to unobstructed rainfall.
- In the event of extensive or heavy rainfall; use the rain delay function or turn off controller — the rain sensor won't know how much rain fell and as soon as it dries it will resume your regular watering schedule. If a lot of rain fell, you don't need to water for at least a few extra days.

Stormwater Master Planning helps protect people, property and the environment against flooding, erosion and water quality problems caused by runoff.
Pouring cooled fats, oils and grease (FOG) into a sealable container and putting it in the trash or taking used oil to a recycling center can help prevent costly sewer backups.
You can save money by shifting your electric use to the lower-priced, off-peak hours or by reducing your overall use.
