Did you know
  • When it opened in 2006, Delphos's sewage plant was the largest flat plate membrane bioreactor facility in the world — and the only membrane plant anywhere running Autothermal Thermophilic Aerobic Digestion on its solids.
  • A town of about 7,000 people built a wastewater plant sized for the organic load of 70,000, because its industries put out that much.
  • The plant's solids are cooked by their own bacteria: the ATAD reactors hold about 140°F with no external heat, producing a Class A biosolid that gets pressed to roughly 22% solids and spread in city parks or handed to…
  • There are 52,000 individual membrane plates in the bioreactor, stacked into 130 double units across five trains — and in a storm the fifth train stops thickening sludge and starts treating sewage.
  • The reservoir has its own chapter of city law: Chapter 931 of the Delphos codified ordinances is the Delphos-Gillmor Reservoir.

Treatment & pressure

How it is treated

The Delphos Water System takes its raw water from the Little Auglaize River via the Delphos Gilmore Reservoir northwest of the city — the river is impounded first rather than pumped straight to the plant, and the reservoir has its own chapter in the codified ordinances (Chapter 931, Delphos-Gillmor…

Supply stress

Not documented as quantity-stressed.

Sewers

Sanitary

A 2006 membrane bioreactor plant discharging to Jennings Creek, built from 2005 to treat industrial organic loadings equivalent to a community of 70,000 in a city of about 7,000. Average dry weather flow is roughly 1.5 MGD; design peak flow is 12 MGD. Wastewater enters an influent pump station on the old plant site through a 48-inch and…

Storm

Delphos runs a combined sewer system, so storm flow goes to the wastewater plant rather than to a separate outfall network — when it rains the plant sees flows in excess of eight times the 1.5 MGD dry weather average, which is why it was built for a 12 MGD…

Mostly estimated. Only 7% of these days come from a gauge standing inside 45833 (Delphos) - the rest are worked out from the nearest gauges around it, so read them as close estimates rather than readings.

48,862 days of records, 1893-01-01 to 2026-10-29. 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 2026-10-31): correlation 0.9515, median absolute difference 0.217 in a month. Built 2026-10-31 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.
