Odd-Even Watering Schedule

The City of Durham has adopted requirements to help make our community a more sustainable place to live. These watering requirements are consistent with irrigation schedules in most of our neighboring communities.

Landscape irrigation makes up a large portion of our consumption, particularly during the warmer months of the year. In fact, irrigation during summer months can increase demand on the treatment plants between 20% - 40%. By improving the efficiency of our irrigation practices, we can reduce consumption, save money, and preserve this precious resource.

The mandatory outdoor irrigation schedule applies to all spray irrigation systems and allows customers to irrigate according to the following schedule:
  • Odd-numbered addresses may water once on Tuesdays, Thursdays, and Saturdays either before 10 a.m. or after 6 p.m.
  • Even-numbered addresses may water once on Sundays, Wednesdays, and Fridays either before 10 a.m. or after 6 p.m.
  • No watering may occur between 10 a.m. and 6 p.m. on allowed watering days.
  • No customers are permitted to water on Mondays.
Odd-Even Irrigation Schedule

Temporary licenses will be allowed to establish new landscapes.
Hand-watering and drip irrigation systems are not restricted.

Installed Sensors
The ordinance also requires that new irrigation systems be equipped with properly operating rain or soil moisture sensors in appropriate locations to prevent irrigation during rain events or when there is sufficient moisture in the ground for plant health and survival. Existing automated irrigation systems must be retrofitted with moisture or rain sensors by November 30, 2009.

The city has also adopted requirements to eliminate water waste. These rules prohibit excessive run-off as a result of irrigation, incorrectly positioned spray-heads, and allowing leaks to go untouched. Durham customers can help to conserve the existing supply and help ensure that wise water use becomes a part of everyday life by following the provisions of the ordinance.
