Separating Distances for Private Pools per Connecticut Public Health Code
Septic leaching area
Check with building/zoning official
Pool accessory structures (decks, filter sheds, etc.) must be a minimum of 10 feet from a septic system or tank.
If your pool filtration system requires backwash to clean the filter media, then a properly sized drywell or leaching area is required for discharge of filter backwash water. The drywell must maintain a 75 foot separation distance from any water supply well. Note: Backwash water is not allowed to discharge to the house septic system!
