Water Main IMPROVEMENTS Along with the other utility improvements, it is necessary to upgrade the water system for fire flow and to add additional pipe in order to provide water service to the proposed new buildings. The estimated average daily demand for the area once it is developed is 120,000 gallons. The demand may peak up to 250,000 gallons per day at its maximum, These estimates are based on statistics for th ropolitan area and general published data. Using these numbers it is conservative to assume the ter use for the developed area will be 3,200 gallons per acre per day, In 2005 the City completed construction of a 0.5 million gallon r wer. Thi r, along with the existing two primary wells, will be sufficient to serve the full velo d area assum e previously stated demand. It should be noted, however, that the fa' of one o the wells on a p m d day would result in the City running out of water and bei u o serv residents. )t is, t ore, strongly recommended that the City proceed with their plans ir eIL ' i It has been determined through analysis that ater system is ca f providing a fire flow of 2,500 gpm for 3 hours to the downtown redevelopm is is equivale ;000 gallons of water, � leaving 50,000 gallons for typical operations du th ich is exa the capacity of the tower. All � mains can maintain this fire flow with the excepti of t -end node on Westview Street. It i is just under 2,500 gpm. If n this node can oped dow connect with the water main on Main Street.
