Allow the chlorinated water to stand in the system for at least six (6) hour, and preferable overnight.
After this, open an outside faucet system until water runs chlorine free. Repeat flush operation on each
faucet in system.
NOTE:
A.Chlorine may break loose iron deposits, slime and organic material. This material will make the
water run colored. The material broken loose may plug pump screens. Do not continue to
run pump if water doesn’t flow.
B. The high level of chlorine required to sanitize a water system is corrosive to most metals and
chlorine solution must not be allowed to remain in water system more than 36 hours before
being completely flushed from system.
After system has been completely flushed, perform a bacteriological analysis on the water
following all applicable procedures.
NOTE:
Always follow the sanitizing procedure required by applicable state or local laws.
EPA Registered:
Well sanitizer pellets are EPA Registered for sanitizing potable water.
EPA Registration No. 50510-1.
LARGE DIAMETER WELLS:
Dug or bored wells should be disinfected in the same way as a drilled
one. Lower the water level as much as possible, remove the sand, silt and debris, and then treat with the
chlorine solution. Mix thoroughly by circulating the water back into the well and use the hose to rinse the
interior
lining of the well. Do not try to disinfect an unprotected, unlined well because new seepage or surface
contamination will flow into the water about as fast as you can disinfect it. Disinfect the pipeline distribution
system as indicated for drilled wells.
SPRINGS AND CISTERNS:
Mix about ½ cup of household bleach in 5 gallons of water and use this
to scrub the walls of the spring box or holding tank. With a constant flow of fresh water from the spring, there
is
probably no way of detaining the chlorine solution in the reservoir for more than a few minutes. However, the
chlorinated water should flow through the pipeline to disinfect the distribution system. Cisterns can be
disinfected in the same way but a source of clean water will be needed to flush the dirty waste out of the
system.
For additional information about how to protect wells and springs and keep them from becoming
contaminated, call or visit your local Cooperative Extension office, or your nearest certified water treatment
specialist.
If this system is used for the treatment of untreated surface waters or groundwater under the direct
influence of surface water, a device found to be in conformance for cyst reduction under the appropriate
NSF/ANSI Standard shall be included upstream of the system.
