Well Requirements for Public Water Systems1. Setback Distances• Minimium set back, 200 ft from septic tank over 2000 flow• Minimum set back, 100 ft from septic tank under 2000 flow2. DEP Well Construction Requirments• Well pad 6’x6’x4’ concrete sloped away from the casing• Casing must extend 12 inches minimum above concrete slab3. Well Operations Definitions• Static level – Level of water when pump is not operating• Pumping or Dynamic Level – Level of water when pump is operating• Draw down – Drop of water level when water is pumped from well• Pumping – Static = Drawdown4. Well Operation Considerations• Well pump packing gland lubrication – Water (aprox one drop per second)• Well casing must be disinfected5. Well Pump Types• Submersible• Centrifugal• Turbine6. Locating a Well• Vulnerability is the most important factor to consider in locating a well sitefrom the health point of view• A well is acidized in order to increase yield• The drawdown in a well is measured from the static water level to thepumping water level• If volatile organic chemicals (VOC’s) are detected, sampling must then beconducted quarterly9
