Other Treatment Systems Other treatment systems such as, greensand filters and sandfilters should be bypassed and disinfected separately from the well according to the manufacturer's instruction manual. Regular disinfection of these types or treatment systems is also recommended. A disinfection system may need to be installed if Total coliform testing indicates that the ground water is contaminated. Two common disinfection systems are the ultraviolet light and chlorination systems. The ultraviolet light system is simpler to operate, however, may require pretreatment to ensure the water is clear enough for this system to work properly with little maintenance.
Maintenance usually consists of replacing the bulb and cleaning the unit annually.
More frequent cleanings maybe required. Maintenance on these systems is usually higher and the water will contain a low chlorine residual. The type of system chosen should take into consideration any other water quality concerns and their treatment requirements.
