With Little Rain, it's More Important Than Ever to Follow Lawn Watering Days and Hours

Watering on the wrong days or hours can result in a fine of up to $500

All water users in unincorporated Hillsborough County are subject to the year-round outdoor lawn watering restrictions. These restrictions are an important way to protect our most important resource - water.

Lawn watering drives peak customer water demand, and the restrictions help to balance the demand and prevent low pressure.

Allowable watering days and hours for most water sources, uses, and methods are limited to twice per week, as follows:

  • Street addresses ending in 0, 1, 2 or 3, watering days are Mondays and/or Thursdays.?
  • Street addresses ending in 4, 5 or 6, watering days are Tuesdays and/or Fridays.?
  • Street addresses ending in 7, 8 or 9,? watering days are Wednesdays and/or Saturdays.?
  • Common areas with or without addresses, locations with no address, and locations with mixed addresses (such as office complexes and shopping centers), watering days are Wednesdays and/or Saturdays.
  • No watering is allowed on Sundays.

Watering may occur in only one of the two designated watering periods per day, between midnight and 8 a.m. or between 6 p.m. and midnight, on the allowable watering days.

Customers using reclaimed water may water on any day of the week either before 10 a.m. or after 4 p.m.

The use of drinking or reclaimed water for watering lawns must not be wasteful and unnecessary. Irrigation systems should be operated in a prudent manner to ensure that water does not collect or run-off from the system does not occur. Irrigation should only be used as a supplement to rainfall.
