Plumbing behind a lake that isn't the water source
Berkeley Lake takes its name from developer Frank Coggins' own Berkeley Blue Granite Quarries business, not from anything on site, and the 1948 dam that created the 88-acre lake was built purely for his 700-acre cottage development. Despite the name, the city's actual drinking water comes from Gwinnett County's system, sourced from Lake Lanier via Buford Dam — Gwinnett stood up that countywide water system in 1958, two years after Berkeley Lake incorporated in 1956.
Seasonal-cottage plumbing meeting full-time demand
A plumbing project on one of Berkeley Lake's original 1950s cottage-era properties should confirm whether the system was ever upgraded from its original seasonal-use sizing, since fixtures built for weekend guests often can't handle a full-time household's daily draw.

What a Berkeley Lake plumber needs first
Let us know if your property is one of the original 1950s cottages, since seasonal-era plumbing may not have been upgraded for full-time use. Include the issue, timing, and access constraints.
Lake Lanier supplies the water, not the lake
Gwinnett County's water system, supplied by Lake Lanier rather than the town's own namesake lake, issues the permits for any supply-line or sewer work in Berkeley Lake.
