(a) The city shall monitor water supply and/or demand conditions on a weekly (or more often) basis and shall determine when conditions warrant initiation or termination of each stage of the DCP.
(b) Unless there is an immediate and extreme reduction in water production, or other absolute necessity to declare an emergency or severe condition, the city will initially declare Stage II restrictions. If, after a reasonable period of time, demand is not reduced enough to alleviate outages, reduce the risk of outages, or comply with restrictions required by a court, government agency or other authority, Stage III may be implemented with Stage IV to follow if necessary.
(c) Under normal circumstances, the CRMWD provides raw water to the city from a combination of five sources:
(1) The Ivie Reservoir;
(2) The Spence Reservoir;
(3) Lake Thomas;
(4) Moss Lake; and
(5) The Martin County Well Field. The Martin County Well Field is used intermittently. The CRMWD sets the ratio based on reservoir level, source water quality, economics and needs of its member cities and customer cities.
(d) CRMWD has the capacity to deliver up to 21 mgd of water from Lake Thomas and up to 40 mgd of Spence Reservoir water from Moss Lake to the 15 mg reservoir located at the city pump station north of the city. CRMWD can gravity flow up to 11 mgd of Ivie/Martin County water to this 15 mg reservoir from the west.
(e) A 27-inch concrete cylinder line conveys water from the 15 mg reservoir to the Big Spring Roy C. Hester Water Treatment Plant. This line currently operates by gravity with a capacity of 12 mgd, but can be boosted to increase the capacity. The water treatment plant has a normal capacity of 12 mgd that can be pushed to 13 mgd for short periods of time.
