Drought Warning

A drought warning implements coordinated response to imminent drought conditions and potential water supply shortages and initiates concerted voluntary conservation measures to avoid or reduce shortages, relieve stressed sources and forestall the need to impose mandatory water use restrictions. Development of alternate sources is initiated where and as appropriate. The objective of voluntary water conservation measures during a drought warning is to reduce overall water uses by 10-15% in the affected areas. Because of varying conditions, individual water suppliers or municipalities may be asking for more stringent conservation actions.
