About this area's water

Did you know
- Amherst sits 2.5 miles from Lake Erie and still owns no piece of the lake: it buys every gallon finished from two neighboring cities rather than building an intake of its own.
- The 'Elyria' water plant that supplies part of Amherst is not in Elyria - it is an Elyria-owned plant at 3628 West Erie Avenue inside the City of Lorain.
- Amherst's water bill has a line item, the Water Supply Cost, that changes every single month because it is a straight pass-through of what Lorain and Elyria charge that month.
- The posted Amherst rate schedule still carries an effective date of January 1, 2015 - the fixed part of the bill has not been re-legislated in a decade; the variable WSC does the moving.
- Before it was a Cleveland-area suburb, Amherst billed itself as the 'Sandstone Center of the World,' and the quarrying motto is still the city's.

Treatment & pressure
How it is treated
Amherst treats no water of its own. It is a consecutive (purchase) surface water system that buys finished Lake Erie water from the City of Lorain and the City of Elyria and distributes it; its CCR carries Amherst's own distribution-system sampling plus the reports of both suppliers. The plants…

Supply stress
Supply volume is not a constraint - Lake Erie is 2.5 miles away and effectively inexhaustible - but Amherst has no plant, no raw water source and no independent production capacity at all: 100% of its water is purchased finished from two upstream utilities, Lorain and Elyria. Everything that happens at those plants passes straight…

Sanitary
Billed by the city's Utilities Department on metered water consumption, with a published minimum of $30.32/month inside the city and $45.48/month outside. Amherst does not publish the name, capacity or receiving stream of the treating plant on its utilities or rate pages; Ohio EPA's 2023 rate survey lists Amherst as providing sewer…
