The Kalaheo area on Kauai was asked Sunday to use only enough water for “essential uses” following a power outage at the Kalahelo deep well site.

The power was restored around noon, but the conservation measures still apply to lower Kalaheo, specifically areas makai of Kaumualii Highway, Kauai County said.

Essential water needs include cooking, bathing and toilet flushing, a news release said.

Water conservation measures include refraining from car washing, turning off automatic sprinklers and outdoor irrigation systems, and using water wisely indoors and outdoors.
