M 2.0 The following are legal methods of swimming pool waste water disposal. M 3.0 No direct connection shall be made between any storm drain, sewer, drainage system, drywell or subsoil irrigation line and any line connected to a swimming pool. M 4.0 Waste water from any filter, scum gutter overflow, pool emptying line or similar apparatus or appurtenance when discharging to any part of a drainage system, shall be provided with a three (3) inch (76.2 mm) trap. M 5.0 Except as provided in Section M-6, the discharge outlet terminal from any pool or filter shall be protected from backflow by an air gap at least six (6) inches (152.4 mm) above the flood rim of the receptor. M 6.0 No scum gutter drain, overflow drain, backwash discharge drain, or pool emptying line shall enter any receptor below the rim unless the pool piping at its deepest point, the bottom of the filters, and the bottom of the scum gutter drain trough or overflow inlets are at least six (6) inches (152.4 mm) above the overflow rim of the receptor. M 7.0 A positive point of potable water supply to each swimming pool shall be established and shall be installed as required by Chapter 6 of this Code. M 8.0 Plans for other than private swimming pools shall be approved by the Health Officer before any water supply or waste discharge permit is issued. M 9.0 All new swimming pools constructed or installed in Fire Zone 4 or in a Very High Fire Hazard Severity Zone and having a capacity of 5000 gallons or more shall have a minimum four (4) inch diameter drain and discharge line connected to a draft hydrant, the type, location, and installation of which shall be approved by the chief of the fire department. |
