Section 444.498 - Disposal of wastewater

1. Provisions must be made for disposing of material cleaned from filters and of backwash water in a manner which will not create a nuisance. The backwash water must be disposed of in accordance with applicable local law and regulation.

2. When drainage to a sanitary sewer or storm sewer is permitted, an air gap must be provided which will prevent any surge or backflow of contaminated water into the spa or the recirculation system.

3. Disposal of diatomaceous earth must be made so that no solids appear in the wastewater. This may be done by using a separation tank, stand trap, or any other method approved by the health authority.
