The total required flow rate to irrigate 2,310 acres within a <br />12-hour watering window is approximately 32,000 GPM during peak season. <br /> <br />Pressurized Transmission System Concel;!! <br /> <br />A pressurized irrigation transmission system is proposed to provide irrigation water "on- <br />demand" throughout the Lake Canal Company service area. As the service area <br />develops and builds out, landscape irrigation water will be needed throughout the area. <br />A network of raw water storage reservoirs, pump stations and pipelines is <br />conceptualized to provide the water required for the service area. <br /> <br />Three storage reservoirs and three pump stations are proposed to service the landscape <br />demands. Currently, two storage reservoirs exist within the Lake Canal conveyance <br />system: Timnath Reservoir and Lake Canal Reservoir #1. Two new reservoirs are <br />proposed: one on the north end of the service area and one adjacent to Timnath <br />Reservoir to assist in treating poor water quality at this location. The new reservoirs and <br />pump stations have been preliminarily sized based on the water requirements presented <br />above. A pipeline network was developed to cover all areas of service. <br /> <br />As future irrigated areas develop, a point-of-connection (abbreviated POC) will be made <br />on the Lake Canal Company transmission pipe system. From this point-of-connection, <br />the developer will design and install, to Lake Canal specifications, a distribution system <br />to provide irrigation water to all desired areas (parks, open spaces, streetscapes, <br />schools, and residential lots). <br /> <br />Aqua Engineering, Inc. <br />June 7, 2004 <br /> <br />Canal Modernization Feasibility Study <br />- 11 - <br />
