These components include an air compressor, air <br />filters, flow meters, ozone generators, and a system timer. Maintenance of the aeration <br />system is required to keep the mechanical components in proper operating condition. <br /> <br />An overflow structure and pipe are typically designed for irrigation ponds to convey <br />excess water away from the pond rather than allowing it to spill over the banks. This <br />scenario may occur during heavy rainfall events or in the case where the delivered water <br />is more than required. The recommended discharge point for this system is an existing <br />open channel lateral or storm swale. <br /> <br />Modifications to the existing Lake Canal Reservoir #1 (South) are not recommended at <br />this time but future upgrade of this reservoir to increase storage capacity is anticipated <br />as a part of an additional study. <br /> <br />Network Components and Eqyjpment <br /> <br />Network Hvdraulic Model <br /> <br />A total flow rate of approximately 32,000 GPM is required to serve the irrigated acreage <br />within the service area. The proposed pressurized system will include two new water <br />storage reservoirs, three new pump stations, and a network of PVC pipelines and <br />fittings. <br /> <br />A hydraulic model was developed to determine the optimum pipe sizing based on the <br />developed pipe routing and existing and proposed reservoir locations. The <br />conceptualized pipe routing follows the existing Lake Canal Company canals, laterals, <br />and rights-of-way. Additionally, other existing canals or laterals were used where <br />possible or logical, such as the Sandyke Lateral. New railroad crossings were avoided <br />by using existing crossings. New highway and road crossings were minimized by using <br />existing laterals that crossed the existing roads. <br /> <br />After the pipe routing was determined, anticipated flow demands in the system were <br />assigned to nodes on the pipe network. These demands were assigned based on the <br />irrigated area within the boundary of a distinct pipe service area. Demands were equally <br />distributed from adjacent pipes. <br /> <br />Pump Stations <br /> <br />All three pump stations contribute to the total flow rate for the Lake Canal Company <br />pressurized irrigation system. It is assumed that all three proposed pump stations <br />operate simultaneously. Each station will include some redundancy to allow for <br />maintenance of the pumps and motors without disrupting the service flow rate. However, <br />if an entire station is taken out of service, the remaining two stations will not be able to <br />provide the total peak day demand. <br /> <br />Aqua Engineering, Inc. <br />June 7, 2004 <br /> <br />Canal Modernization Feasibility Study <br />- 14- <br />
