LAWRENCEVILLE -- Gwinnett's Board of Commissioners approved Tuesday the adoption of a water and wastewater master plan, a document which asserts the county's plans to continue depending upon Lake Lanier for its long-term water supply.
The master plan, which focuses on needed capital investments to comply with regional plans through the year 2030, was developed over several months before being approved last week by the Gwinnett County Water and Sewage Authority.
The document -- which says Gwinnett will "continue to defend its right to the use of" Lake Lanier for water -- was approved unanimously during Tuesday's Board of Commissioners public hearing agenda.
Commissioner John Heard took it upon himself Tuesday to defend Gwinnett being "single-sourced" in depending on Lanier.
"We do recognize that we're single-sourced," Heard said, "but we also ask that all parties throughout the Southeast region recognize there's a good reason for single sourcing -- because we don't have any other alternatives."
Computer models were used when developing the master plan and helped predict growth in the county over the next 20 years to find potential future bottlenecks and identify solutions, officials said. The results showed that most current water and wastewater systems could handle the growth, they said.
A 24-member citizen advisory panel also helped shape the plan.
Projects and priorities recommended in the 2030 plan, which can be found in its entirety at gwinnettcounty.com, included:
-- Additional water treatment at the Shoal Creek Filter Plant, with an estimated cost of $56 million;
-- Sixteen projects to provide additional "water transmission capacity," particularly to serve the Interstate 85 and Ga. Highway 316 corridors, that would cost an estimated $280 million;
-- Capacity upgrades for collector sewers, in 14 projects totalling an estimated $16 million; and
-- Seven wastewater treatment projects, including expansions at the Crooked Creek Water Reclamation Facility and F. Wayne Hill Water Resources Center, at an estimated cost of $600 million.
