About this area's water
Did you know
- Mineral Ridge's water passes through two resellers before it reaches a tap: the county district buys from Niles and Youngstown, and both of those cities buy the same water from the Mahoning Valley Sanitary District.
- The dam holding back Meander Creek Reservoir is itself named the Mineral Ridge Dam - an earthen structure finished in 1932, 60 feet high and 3,480 feet long at its crest, impounding about 11 billion gallons (62,000…
- MVSD owns 5,500 acres around the reservoir, enclosed by 35 miles of fence and reforested with four million evergreens, to keep its watershed clean.
- The community's namesake industry was iron, not water: black band ore found beneath its coal seams in the 1850s was sold nationally as 'American Scotch Pig.'
- Mineral Ridge gave up its village charter in 1917 and has been unincorporated ever since, yet the water system still carries its name - and now spans two counties, Trumbull and Mahoning.

Treatment & pressure
How it is treated
Mineral Ridge buys finished water; it treats none of its own. EPA's facility inventory shows two active consecutive connections, from Niles City PWS (OH7802403) and Youngstown City PWS (OH5002303), both surface water, and both of those cities draw from the Mahoning Valley Sanitary District's…

Supply stress
Mineral Ridge sits at the end of a resale chain and owns no source of its own: the county district buys from Niles and Youngstown, which both buy from the Mahoning Valley Sanitary District, which draws from Meander Creek Reservoir. That leaves it exposed to upstream treatment problems as much as to bulk-rate changes - the July 2026…
