ATTACHMENT 11BiA <br />GENERA SPECIFICATIONS <br />1. The proposed inter -tie shall be metered with a meter <br />suitable for the required fire flows and for any <br />domestic water requirements which might occur. The <br />high flow recording portion of the meter shall be <br />transmitted by telemetering over a leased telephone <br />line to the Santa Ana Walnut Water Plant to differen- <br />tiate readily between a high flow through the connect- <br />ion and a large main line leak. <br />2. The automatic valve control must be adequate to deli- <br />ver both the anticipated fire demand and the domestic <br />flow. The valve will require pressure sensors and <br />recording pressure gauges both upstream and down- <br />stream of the pressure regulator that will sense a <br />drop in pressure of the Costa Mesa system below a <br />predeterftindd minimum. The pressure regulator valve <br />will then open allowing Santa Ana pressure and flow to <br />make up the required amount. <br />3. Personnel certified as qualified to operate and main- <br />tain automatic valve equipment shall operate the <br />automatic valves bimonthly and certify to their opera- <br />tion and make whatever repairs are found necessary. The <br />cost of this operation, test and repairs shall be <br />borne by the District. <br />4. Personnel certified as qualified to test and maintain <br />large meters of this type shall operate the meters <br />bimonthly and test the meters annually and make what- <br />ever repairs are found necessary. The cost of this <br />operation, test and repairs shall be borne by the <br />District. <br />�'1 <br />
