Authority says Griffin sold water beyond system capacity; will set technical transmission metrics
Summary
Board members said the City of Griffin contracted to sell water to Hampton at volumes the authority's current model shows it cannot reliably deliver without system improvements; the authority will adopt metrics defining allowable flow and required upgrades and will require pay-for improvements where necessary.
The Spalding County Water and Sewage Facilities Authority told the board on April 16 that a water sales agreement between the City of Griffin and the City of Hampton appears to promise delivery levels the authority’s current system cannot provide without major upgrades.
Authority members and staff said their hydraulic modeling identified a safe additional flow near the county line of about 100 gallons per minute under present conditions. Staff raised concerns about tank recharge, residual pressure (they noted a 40-PSI minimum target), head loss, velocity-related wear on mains and potential reductions in fire flow capacity. A staff member said Hampton contracted for water before the authority’s updated modeling results were available.
The board directed staff to finalize a formal metrics document that will define the authority’s objective technical limits and how requests to transmit water through authority mains will be evaluated. Staff said the document will show what upgrades would be required to deliver higher flows and that the authority will require the party seeking transmission to identify who will pay for system improvements.
Board members reiterated that the authority will hold all outside water users to the same standards so the system and fire-flow protections paid for by Spalding County ratepayers are not compromised.
