As noted above, the ideal location for filtration and water treatment system equipment is beneath the pools and water features. If this is not possible, allowance should be made to ensure that the floor supporting the pumping equipment is set at an elevation at minimum of 3’ below water level, or as required to ensure that pump volutes will be flooded.
Ample allowance for containment and drainage should be considered.
In elevated pool construction, equipment access for both construction and maintenance are important considerations. The doors, passageways, elevators, and hallways must be of sufficient dimension to allow for the movement of the largest anticipated piece of equipment.
It is a fact of pool and water feature operation that certain chemicals will be used for sanitation and pH control as well as for maintenance. Access and path of travel are important considerations. Some of these chemicals may be oxidizers and classified as hazardous. Transporting them through occupied public spaces could prove problematic. Back-of-house access is preferable if a possibility.
Sound vibration not only passes through the air, it can be structurally borne as well. If the pool, spa, water feature or its related filtration and water treatment equipment is located over or adjacent to occupied or acoustically sensitive space, consideration must be given to sound and vibration control. A source of potentially problematic sound and vibration include filtration equipment such as pumps, hydrotherapy jets and air induction equipment in hydrotherapy spas, and in some cases the sound of people thumping around the bottom of a stainless steel spa or swimming pool. As such, consultation with an experienced and qualified acoustical engineer is recommended.
In summary, successful elevated pools and/or water feature design depends upon meeting the inherent challenges and demands of structure, appropriate material selection, waterproofing, drainage and acoustical control.
