About this area's water

Did you know
- Geneva runs no water plant at all - every drop is bought wholesale from Aqua Ohio's Ashtabula system and pulled from an intake sitting offshore in Lake Erie.
- The city's sewage plant uses a trickling filter and discharges into Cowles Creek, a stream Ohio EPA classifies as salmonid habitat.
- Geneva gives residents an annual sewer credit for swimming pools deeper than three feet that do not drain into the sanitary sewer.
- The wastewater department has already bought two chopper pumps at $13,000 and $18,000 to deal with flushed wipes, and puts the cost of screening them out of the plant at about $1.92 million, or $768 per customer.
- Geneva publishes water quality reports back to 2018 but no water rate schedule at all.

Treatment & pressure
How it is treated
Geneva Water Works operates distribution only. It buys bulk finished water from the Aqua Ohio - Ashtabula Water System, which draws surface water from an intake offshore in Lake Erie and treats it; Geneva's water is disinfected using chlorine. The city's 2025 CCR notes that Aqua maintains…

Supply stress
Geneva has no source of its own; all of its water is purchased from Aqua Ohio's Ashtabula system, which draws from Lake Erie. The 2025 CCR states that although Aqua's intake is offshore, the proximity of several onshore sources raises the source water's susceptibility, and lists municipal and industrial wastewater discharges, residential…

City-operated. The Geneva Wastewater Treatment Plant treats by trickling filter followed by advanced treatment and discharges to Cowles Creek, which Ohio EPA designates a low-flow, warm water, salmonid habitat stream. Design capacity 2 MGD with wet weather flows to 5 MGD; collection system of about 38.3 miles of gravity sewer (6 to 30…
Storm
No separate storm water utility or fee was found. The city posts a sanitary sewer overflow annual report (2016) but publishes no storm water rate or program page.
