  • Page 11: Disinfection Procedure

    SANITATION PROCEDURE FOR INSTALLATION AND BULB REPLACEMENT: HOW TO DISINFECT A WATER SYSTEM: Every new well, or existing water supply system that has been disrupted for service or repair, should be disinfected before it is returned to use. Water in the well and storage tank should be treated with a strong chlorine solution to destroy disease organisms.
  • Page 12 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.
  • Page 13 REMEMBER - To make your water supply safe: - Locate your well properly. - Protect it from surface contamination. - Test water periodically for coliform bacteria. (Home-yearly, Farm-2X yearly) - Chlorinate, or filter and disinfect the water if necessary. When installing an ultraviolet disinfection system, a prefilter with sump may serve as a source to sanitize the water lines only.
  • Page 14 DRILLED WELLS: 1. Remove the cap or seal from the casing and measure the depth of the water in the well, then refer to Table 1 to determine how many chlorine pellets should be used. In some instances removing the seal to measure the water can be a difficult task, and it is easier to estimate well and water depth from well log or other records.
