Read the bill first
Well pump versus city water
A well has a pump and a pressure tank. City or district water has a meter and a main. Aurora's in-city customers are on a utility. Do not buy a well pump for a metered house.
Check the bill and the property. Douglas County says to verify water, sewer, well, and septic before you dig, which matters on unincorporated lots such as Highlands Ranch. If the source is a well, repair is well pump repair and a new pump string is installation. If the source is a utility, low pressure is pressure or the service line. A state well permit was not copied onto this page. Ask before anyone drills.
Questions to settle first
How do I tell which one I have?
The bill. A city or district account is not a well. A pressure tank and no water bill can mean a well. If you are unsure, do not order a pump. Douglas County's permit page tells owners to verify the source before they dig.
Can Aurora Water customers ignore this page?
Yes, for the pump itself. Your outage or pressure problem goes to Aurora Water or to the house plumbing, not to a well casing. This page exists so a rural lot is not given city-main advice, and a city house is not sold a well.
Does a new well need a permit?
Often yes, from the state, and this guide does not quote that rule line by line. Drilling is not the same as replacing a pump in a well that already exists. Ask before the rig is booked. Ask them to write that limit into the quote before you compare it with another company.
