-2- <br /> Also due to the significant system improvements made since 2009, and changes in water usage <br /> by some of our major customers since 2006, the Water System Master Plan will be updated so <br /> that it can be more effectively used as a decision making tool for water system improvements <br /> needed to meet current and future drinking water and fire suppression requirements. Examples <br /> include: <br /> • Determine the optimal extent of the geographic boundaries of the City's water system <br /> • Determine how much more water could be delivered to an existing customer that is <br /> considering expanding operations or fire suppression capabilities <br /> • Determine where new businesses that requires high volumes of water could be located <br /> Attached are two examples of items that need to be updated. The first is the City's existing and <br /> potential future water service area. The second is the water system's predicted water pressure <br /> during the highest possible hour of water use by all customers including a high demand for fire <br /> suppression water. In this example, all areas need to have at least 20 pounds per square inch <br /> (psi) of water pressure. <br /> Strand's scope of services will consist of these major categories: <br /> • Hydraulic model update <br /> • Steady state analysis of the water distribution system <br /> • Several extended period simulation analyses of the water distribution system <br /> • Water age analysis of the water distribution system <br /> • Master plan update with improvement recommendations for the entire water system <br /> The agreement is structured so that the City may opt to have some or all of the services <br /> completed, depending on the results of the previous services. If all of the services are completed, <br /> the total cost will not exceed $110,000. <br /> POTENTIAL OBJECTION: <br /> None foreseen. <br /> STAFF REFERENCE: <br /> Jerry Stevens, Engineering Services Coordinator, 217-424-2833 orjstevens@decaturil.gov <br /> BUDGET/TIME IMPLICATIONS: <br /> This expenditure is included in the 2014 Water Non Lake Capital Budget. It is anticipated that <br /> the project will take approximately 8 months to complete. <br /> Attachments <br /> cc: Brian Hackman, Strand Associates, Inc. <br /> Randy Miller, Water Services Manager <br /> Matt Sekosky, Fire Chief <br />
