Water Conservation Resources & Programs

Drought is here - please conserve water! Is your yard drought-ready?

Outdoor Conservation

Hillsborough residents use a significant amount of water on their landscapes. Over two-thirds of all water used in Hillsborough is used for irrigation, pools, and other outdoor purposes. Water conservation efforts have traditionally focused on indoor water use (water efficient toilets, shower heads, washing machines, etc.). Reducing outdoor water use represents the greatest opportunity for Hillsborough to conserve water. The Town has several programs to promote outdoor water conservation.
