Discharging water directly from your pool into the swale or any other drainage feature is not allowed. Your pool can be emptied onto the lawn and allowed to sheet flow into the swale or other drainage feature. Running the water across the lawn first allows chemicals and other contaminants to be removed prior to the water entering into the stormwater system. If you drain it in the lawn we ask for about 20-25 ft before the swale or as far back as possible. To drain the entire pool there may be the need for some measures to be installed to trap any sediments and provide treatment prior to entering the swale. This volume of water is typically discharged at a greater rate than can be treated across the yard. Silt fence, hay bales or some other methods can be used to trap sediments on the property before entering the system.
