Did you know
  • Willard treats river water only after pumping it roughly 3 miles into a man-made 215-acre, 2.3-billion-gallon upground reservoir -- effectively a giant pre-settling basin before the plant ever sees it.
  • The city is a regional wholesaler, not just a retailer: its 2025 CCR says the system serves about 9,255 people across Willard, Celeryville, New Haven, the Village of Plymouth and rural customers, and Northern Ohio Rural…
  • In May 1998 the Willard plant was picked out of roughly 6,000 Ohio water plants for the state's Outstanding Public Water System Award.
  • A single April 2026 storm triggered a 15-hour combined sewer overflow that released 7.78 million gallons into Jacob Creek.

Treatment & pressure

How it is treated

Raw water is drawn from an intake on the West Branch of the Huron River and pumped about 3 miles to the 215-acre, 2.3-billion-gallon Willard Up-ground Reservoir east of town, then treated at a Class III surface water plant rated at 3.2 MGD design capacity (currently averaging about 1.3 MGD).…

Water pressure

Not published. The city posts a water FAQ, water rules and regulations, and a bill-explainer document, none of which state a distribution system pressure; no psi figure appears in…

What it costs

$5.50 per 1,000 gallons

Typical household bill about $43 a month for water.

Inside-city residential rates effective January 1, 2026 (3/4" meter): $5.60 monthly base + $5.50 per 1,000 gallons for the first 500,000 gallons ($2.85 per 1,000 above that) + a…

EPA compliance record

Lead at the tap: 90th-percentile result 0 ppb in 2026 (action level 15 ppb).

EPA health-based violations since 2015:

  • 2024Lead and Copper Rule (lead) · treatment technique violation · returned to compliance

2 violations of any kind logged since 2020, 1 of them paperwork (monitoring, reporting, public notice or consumer report).

Supply stress

Water supply itself is not constrained: the plant's 3.2 MGD design capacity is well above current production of about 1.3 MGD, and the 2.3-billion-gallon upground reservoir buffers river flow. The real stress is wet-weather sewer capacity. Willard runs a combined sewer system, and screened combined sewage overflows to Jacob Creek during…
