You probably either have a well or a cistern you use at this time. They must not be connected in any way to the line coming in from the LPWWA meter unless you follow all the Colorado laws regarding Cross-Connection (Back-flow preventer). Check with your contractor as to what they recommend. See excerpt from LPWWA Rules and Regulation (R&R) regarding this. See full R&R under Document menu.
