off- of the cooling towers, the utility demands of this facility are substantial. Electric Service Target will requite that a total service load of 8,884 Kw/10,452KV A, 0.85 power factor be provided to the site by August 2006 for commissions of the Technology Center. Upon completion in fall of 2007, The facility will requite two feeds of 15KV nominal service to a disconnect location on site. Conduit from the disconnect location to the facility will be provided by the owner. In addition to the main power feeds, Elk River Municipal Utilities will also run a feed for temporary power to be used for construction activities. This power source will be maintained indefInitely to power the life safety circuits within the building. Elk River Municipal Utilities is in process of determining whether they can meet the temporary service demand for commissioning with their existing infrastructure. They have determined that in order to meet the ultimate demands, they will have to add a new electrical substation. This is a substation that they have been recently considering, and the revenue from the Target facility (along with existing demand) is expected to generate adequate revenue to support such a facility. Water Main The Technology Center has a total demand (excluding irrigation) of 137,000 gallons per day. This includes a peak flow demand is 142 GPM (204,480 gallons per day), or average flow of 95 GPM (136,800 gallons per day) to the cooling towers. The domestic use for occupants will require a peak flow of 60 GPM (86,400 gallons per day) and an average flow of 900 gallons per day. Target's fIre flow requirements are 1270 GPM peak flow with activation of a dry sprinkler system and a hose to extinguish a fIre. There is an existing 10" Water Main that runs east west just north of the proposed north property line of the Target site that was recently constructed. Hydrant flow tests recently taken indicate that the flow demands can be met by the municipal system, but a private fIre pump on the interior of the building will be required to meet the required pressures. The utility plan proposes an 8" public water main loop around the perimeter of the building with public fIre hydrants within a 20' wide public drainage and utility easement. The building services will be private and will not be within easements. Sanitary Sewer The sanitary sewer requirements for the facility are 114 GPM peak flow, or 78,660 gal/day average. The 12" PVC Sanitary Trunk Main that runs east west just north of the proposed north property line of the Target site provides more than adequate capacity for this loading. The City Engineering Department has said that the treatment plant can easily handle this flow, and the flow will actually help justify a recently constructed lift station near the Business Park that is currently running under capacity.
