About this area's water

Did you know
- New Philadelphia's wells have carried industrial solvents since 1981, and the plant aerates the raw water specifically to blow those volatile organic compounds off before it reaches customers - trichloroethylene was…
- The water table in the city's wellfield sits only 10 to 15 feet below the ground surface under thin, permeable sandy loam, which is why Ohio EPA rates the source highly susceptible to contamination.
- The city softens its water by ion exchange before you get it, and still reports 111 ppm hardness (6.49 grains per gallon) at an average pH of 7.8.
- All 4 million gallons of the city's water storage sits in three steel standpipes - 0.5, 1.5 and 2 million gallons - rather than in elevated towers.
- The city's 2024 notice of violation was for what its water quality report left out, not for anything in the water: it had omitted the wellfield susceptibility report and its license-to-operate status. The 2025 report…
History5
- 1981Volatile organic compounds first detected in the city's distribution system; the existing groundwater supply has required VOC treatment ever since.
- 1987Aeration proposed as the means of stripping VOCs out of the well water, and it remains part of the treatment train today.
- 2023City participates in the fifth Unregulated Contaminant Monitoring Rule round (April and October sampling), turning up only trace PFAS.
- 2024City receives a notice of violation over its published water quality report, for omitting the wellfield susceptibility report and license-to-operate status and for two table-formatting problems. This…
- 2025City issued a green unconditional license to operate; no regulatory testing exceeded any MCL during the year.

Treatment & pressure
How it is treated
Four groundwater wells screened in unconsolidated sand and gravel in the Tuscarawas River Valley aquifer, pumping approximately 2.3 million gallons per day. The treatment plant at 310 Mill Ave SE uses ion exchange for softening, greensand filtration for iron and manganese removal, aeration to strip…

Water pressure
No psi figure or pressure-zone information is published. The system's pressure and fire-flow storage come from three steel standpipe reservoirs totaling 4 million gallons.

What it costs
$6.11 per 1,000 gallons
Typical household bill about $31 a month for water.
From the city's 2026 Inside Water/Sewer/Garbage rate sheet (water/sewer increase effective February 2026; garbage increase November 2024). Water minimum is $22.60/month, which…

EPA compliance record
Lead at the tap: 90th-percentile result 1.4 ppb in 2024 (action level 15 ppb).
EPA record: no health-based violations since 2015.
2 violations of any kind logged since 2020, 2 of them paperwork (monitoring, reporting, public notice or consumer report).
Supply stress
Ohio EPA continues to assign New Philadelphia's drinking water source a HIGH susceptibility to contamination, for four stated reasons: a thin, highly permeable sandy loam soil layer that offers little protection from spills at the surface; a water table generally only 10 to 15 feet below ground in the sand and gravel aquifer; largely…
Sewers
Sanitary
The city operates its own wastewater treatment plant at 1422 Delaware Drive SE, using biological treatment, disinfection and sludge processing, and reports removing 90-95% of organic material and suspended solids to meet Ohio EPA standards. Collection is by gravity sewer plus 14 lift stations serving low-lying areas. The city does not…
Storm
New Philadelphia states it runs a fully separate sanitary and storm sewer system, so stormwater does not enter the wastewater plant; the city credits this with preventing overflows. No separate stormwater utility fee appears on the 2026 rate sheet, which…
