Power Outages and Private Water Systems (PWS)

The impact to your drinking water supply during a power outage depends on the source of your water and the type of system. Most private water systems use water wells for the source of drinking water. Other water systems in use in Ohio include springs, rainwater cisterns and ponds. All of these systems use pumps, and some systems such as springs, rainwater cisterns and ponds, use treatment equipment to filter and disinfect the water supply to remove harmful bacteria and protozoans. During a power outage, the pumping systems will not operate and a limited quantity of water is stored in the pressure tank and water lines. Treatment units also need electricity and will not perform the function of treating the water, making the water unsafe for drinking.
