Tate-monroe Water Association

• Built in 1969-1970 with 179 miles of pipe, Tate Monroe was then the largest private water system in Ohio; it has since grown to about 418 miles of main serving over 9,000 customers across eight townships.
• Its wells sit right beside the Ohio River at Clermontville and Moscow - eleven vertical wells plus one collector well - so the supply is effectively river water filtered through the riverbank aquifer.
• It is a member-owned nonprofit rather than a city utility: customers pay a $10 membership fee, the board meets the second Tuesday of every month, and any member can call and ask to be put on the agenda.
• Sixteen pressure-reducing stations and two booster stations are needed to manage the hills of southern Clermont County, backed by about 4.95 million gallons of storage.
• The association reports no lead, no galvanized-requiring-replacement and no unknown-material service lines anywhere in its distribution system - unusual for a system of this age.

How it is treated

Groundwater from the Ohio River Valley aquifer: eleven vertical wells and one collector well sited along the Ohio River at Clermontville and near Moscow. Water is treated at two plants - Idlett Hill Treatment Plant (2120 Idlett Hill Road, New Richmond) and Freedom Crossing Treatment Plant (1865 US…

EPA compliance record

Lead at the tap: 90th-percentile result 0 ppb in 2023 (action level 15 ppb).

EPA record: no health-based violations since 2015.

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

Correction to the previous draft. TMWA's own water quality report states that the aquifer supplying its wells 'has a high susceptibility to contamination, due to the nature of the aquifer in which the drinking water wells are located and the existing potential contaminant sources identified.' That is inherent to a shallow riverbank…

Sanitary

None - Tate Monroe is a water-only member-owned association. Its published rate schedule and services cover water service only; sanitary sewer in southern Clermont County is provided by other entities (the Clermont County Water Resources Department serves parts of the county), not by TMWA.

Storm

Not applicable - the association operates no storm sewer utility and publishes no stormwater program. The previous draft's statement about member townships relying on on-site septic systems was unsourced and has been removed.
