Did you know
  • Del-Co is a member-owned nonprofit 501(c)(12) cooperative, not a city department, licensed by Ohio EPA to run four plants and thirty elevated tanks across eight central Ohio counties.
  • Its six above-ground reservoirs hold more than 2.6 billion gallons of raw water, banked during high stream flows for use when the rivers run low.
  • Nearly all of it comes from one basin: the Olentangy River, O'Shaughnessy Reservoir and Alum Creek Reservoir all sit in the Upper Scioto watershed, with Knox County wells the lone exception.
  • Treatment starts with potassium permanganate dosed into the raw water for one specific reason: killing zebra mussels before they reach the plant.
History5
  • 1969Del-Co Water Company founded by Ralph Scott, Timothy McNamara and Gerald Solt, financed through the USDA Farmers Home Administration.
  • 1969Original system: a 1-million-gallon-per-day treatment plant, 200 miles of underground pipe and a single elevated tank.
  • 2001In October 2001 Ohio EPA approved Del-Co's Wellhead/Drinking Water Source Protection Plan for the Knox County well field.
  • 2025Effective May 1, 2025 Del-Co scrapped minimum allowances and dropped its conservation tier from 25,000 to 10,000 gallons a month.
  • 2026Effective May 1, 2026 rates rose again: $5.00, $8.50 and $12.00 per 1,000 gallons across three tiers, base fee up $1 to $15.00.
Treatment & pressure

How it is treated

Raw water gets potassium permanganate for zebra mussel control, then ferric chloride and lime in a flash mixer, settling, carbon dioxide stabilization, filtration through fine coal and silicate sand, chlorine, fluoride, and phosphate for corrosion control.

Water pressure

Published: Del-Co says it has historically delivered 40-100 psi, per the Recommended Standards for Water Works. Roughly thirty elevated tanks span eight counties.

What it costs

$5.00 per 1,000 gallons

Typical household bill about $48 a month for water.

Effective May 1, 2026: $5.00/1,000 gal to 4,000; $8.50 to 10,000; $12.00 above; plus a $15.00 monthly base for a 5/8-inch meter. Residential.

EPA compliance record

Lead at the tap: 90th-percentile result 0.8 ppb in 2024 (action level 15 ppb).

EPA record: no health-based violations since 2015.

Supply stress

Del-Co calls its Olentangy River, O'Shaughnessy and Alum Creek sources highly susceptible to contamination from farm runoff, septics and road and rail crossings, and its Knox County wellfield relatively so. Output averages near 13 MGD against 45 MGD design capacity in fast-growing Delaware County.

Sewers

Sanitary

Del-Co is a drinking-water-only cooperative and provides no sanitary sewer service. Sewers in its territory are run by local municipalities, townships or county sewer districts.

Storm

Not applicable. Del-Co operates no storm sewers; stormwater is handled by the townships and municipalities across its eight-county service area.

48,829 days of records, 1893-01-01 to 2026-10-30. Source: NOAA NCEI GHCN-Daily, 3,240 gauges in and around Ohio. A day is "gauged" when a gauge standing inside the boundary reported it, and the value is the mean of those gauges. Otherwise it is interpolated by inverse distance from every gauge reporting within 50 miles. Nothing is carried forward, back-filled or smoothed. Against NOAA nClimDiv county monthly precipitation over 136,848 complete county-months (checked 2026-11-01): correlation 0.9515, median absolute difference 0.217 in a month. Built 2026-11-01 from the Cracked Buckeye precipitation archive. Snow is the softer number — snowfall is measured by hand with a ruler, no agency publishes a gridded county snowfall series, and blowing snow defeats every observer.
