Currently the Agencies have a number of <br /> emergency interconnections between them. In addition, each of the Agencies has both groundwater_ <br /> and imported water supply sources sufficient to meet their normal operating needs. <br /> The Four Aeency Interconnection Studv Project: <br /> The Agencies have expressed an interest in a joint investigation to study the adequacy of existing <br /> interconnections in various emergency outages or extreme drought conditions. The project will <br /> inventory and analyze the adequacy of the existing interconnections, define operational requirements <br /> for each interconnection, and quantify the availability of water supply from each agency in various <br /> scenazios. A request for proposals was issued to complete the Four Agency Interconnection Study <br /> (the "Study"). The scope of work for the Study includes the following: <br /> • Identify and chazacterize demand requirements and supply sources for each Agency <br /> • Identify and chazacterize existing interconnections for each Agency <br /> • Create a hydraulic model <br /> • Identify and model potential emergency and supply outage scenazio for each Agency <br /> • Recommend interconnection improvements for each Agency <br /> • Cost Estimate and potential grant funding opportunities <br /> Requests for Proposal for engineering services were sent to five firms: AECOM, Brown and <br /> Caldwell, DCSE, RBF Consulting, and Stantec Consulting. Each of the four Agencies reviewed and <br /> ranked the four proposals. The Agencies' evaluation of the proposals resulted in a recommendation <br /> of RBF to complete the Study. Representatives from the Agencies met with RBF and negotiated a <br /> final scope and cost of $127,000. <br /> The cost of the Study shall be shared among the Agencies. Each of the four Agencies will pay a <br /> proportional share of the cost based on a combination of the total number of existing interconnections <br /> and miles of pipes in the study area for each agency. The cost to be allocated to each Agency shall be <br /> as follows: <br /> 1 <br /> <br />
