Outdoor Fill-And-Drain Tub And Shower Adequacy Review

Outdoor tubs and showers can be added as guest amenities when the existing water and wastewater systems are properly reviewed. For motel, cabin, rental, and hospitality properties, the key issue is whether the new fixtures increase system demand or create a change in approved occupancy.

Water And Septic System Review

The engineering review starts by checking the existing private water supply, existing septic system, current building use, proposed fixture count, and estimated additional flow. In this project example, the proposed work included four outdoor fill-and-drain tubs and four outdoor showers connected to the existing private septic system.

No Occupancy Increase

A major part of the review is confirming that the work does not add new rooms, dwelling units, bedrooms, or sleeping areas. When the proposed fixtures are only accessory amenities, the added water and wastewater demand can be evaluated separately from lodging capacity.
