HARRISBURG AREA LAND USE PLAN 2.10 Utilities Public Water Supply, Treatment and Distribution a. Supply The Town of Harrisburg initially provided water via wells, but for many years, it has depended on the City of Concord for most of its supply. The Town has an ongoing 10 -year contract with Concord. Under this contract, Concord guarantees a supply of 30 million gallons per month (approximately 1 million gallons per day, or MGD). The Town has flexibility where summer usage, due to irrigation, exceeds the allotted amount. Winter usage, meanwhile, is well below that amount. While Concord has approximately 80% of its current rated plant capacity "committed," or reserved based on commitments to specific projects, Concord is in the process of two initiatives to provide more supply. The first is the inter -basin transfer (IBT) Permit to transfer another 10 MGD from Charlotte - Mecklenburg Utilities (CMU) /Catawba River (this permit is currently being challenged). The second is a raw water transmission main connection with the City of Albemarle. While the contract negotiations with Albemarle are relatively resolved, the project has significant design, permitting and construction hurdles ahead. Concord has included an additional 1 MGD allocation in its projected supply needs for Harrisburg. These initiatives, given success in defending the IBT Permit and completion of the Albemarle connection, should address the town's needs well into the future. Long range, the town is fully dependent on the Concord system for water supply. Should the challenge to the IBT 10 MGD transfer be successful and /or the connection to Albemarle somehow be delayed or fail to occur, there is the potential for supply issues for the town in meeting the growth and development needs of its service area. A more specific analysis of current and projected needs is anticipated to be included in the recently completed Draft Water / Sewer Master Plan. The town has three connections to the Concord System all protected and metered as well as two connections to the CMU system through the Concord system. While the town has its own elevated water storage tanks, the hydraulic gradient for the town's system is somewhat dependent on Concord's tanks and distribution system feeding the town's system. With respect to long -range projected water demand, some adjustments to the Draft Water / Sewer Master Plan may evolve in support of the recommendations of the land use plan. The town also has a site designated for a future elevated storage tank. PART II: EXISTING CONDITIONS AUGUST 010 Attac meA number 1 G -1 Page 339
