Why Dover homes need these repairs
Dover is Delaware's capital, home to state offices, Dover Air Force Base, Delaware State University and many renters, with a historic core around The Green and newer subdivisions to the west. The city pumps all its water from wells in three aquifers. Flat land with a high water table, humid summers, hard groundwater with iron, and aging homes near downtown drive most of the sump pump, water heater, softener and drain calls here.

Dover's water supply and your plumbing
Dover's water is groundwater from 9 wells in the confined Cheswold aquifer, 6 in the confined Piney Point aquifer and 6 in the unconfined Columbia aquifer. [1]
Water from the deep Cheswold and Piney Point wells is chlorinated and pumped directly into the distribution system. [2]
A shallow well field of seven wells supplies the city's water treatment plant. [3]
Dover plumbing questions
What should I do if my sump pump stops working in Dover?
Check the power and the float, then call before the next storm; a failed pump is usually replaced, and a battery backup helps during outages. Why it comes up in Dover: A high water table floods crawl spaces and basements.
When is a leaking water heater an emergency in Dover?
A leak from the tank itself won't stop and usually means replacement; turn off the gas or power and the cold-water valve, then call. Why it comes up in Dover: Mineral-heavy well water scales tanks.
Where does Dover's water come from?
From city wells in the Cheswold, Piney Point and Columbia aquifers; there's no river or reservoir supply.
Why does my Dover water sometimes look brown?
Groundwater carries iron and manganese; flushing hydrants or a change in wells can stir it up. Run cold water until clear and call the city if it doesn't.
I'm stationed at Dover AFB and renting off base. Who fixes plumbing?
Your landlord, under Delaware's landlord-tenant code; report problems in writing and keep a copy.
Do Dover homes need sump pumps?
Many do. The water table is high on flat Kent County land, so a working pump and backup help after heavy rain.
