About a year ago we installed a new well to supply the entire campground’s water. I wouldn’t normally consider installing a new well an energy conservation upgrade, but in our case it was due to the poor condition of the old well. The inside of the casing of the existing well was severely deteriorated causing large amounts of rust to flake off and fall to the bottom. These rust flakes would continually become clogged in the intake of the pump, forcing the pump to work much harder. The system was not able to keep up with demand, and during the summer when the campground was full the pump would run continuously instead of cycling to maintain pressure in three 40 gallon tanks. System performance all around was very poor, having low water pressure throughout the campground while using excess electricity.
The new system works much better and consists of a Franklin Electric variable speed pump and control unit. The three 40 gallon pressure tanks were replaced with a single 5 gallon unit that fits inside the well casing. The variable speed drive allows the system to function properly using a small pressure tank without excessive pump cycling on and off compared to a simple 1 speed pump. Another benefit is the elimination of an above ground “pumphouse” where the pressure tanks are normally housed. An building above ground for the pressure tanks has to be heated, where contrarily a system like ours eliminates this building in turn saving the energy that would be needed to heat it during the winter.
The new water system provides guests with much better water pressure while saving energy by having a properly functioning pump and eliminating the need for a heated structure to house the pressure tanks.
