Construction
The construction of a natural swimming pool is similar to that of a chlorine pool. One of the differences being that an area the same size as the swimming area is used as a planting zone or regeneration zone. (Fig.1)
The plant zone is separated from the swim zone by a wall which stands about 20cm higher than the plant area’s gravel filtration system. (Fig 2)
When the pool is filled, the water will link the plant area to the swim area.
Pipe work and traditional inner workings of a chlorine pool are similar to that of a natural pool. Pipes connect the planting zone to the swimming area, and water pumped from drains in the bottom of the pool pump bring water round and back through into the planting zone.
Through this process the water is oxygenated and energised, and warmed too, as the sun heats the shallow areas quickly, meaning there is little need for extra expensive heaters. (Fig. 3)
The planting of carefully selected native species of aquatic plants is an extremely important part of the construction process. The correct species will ensure not only the right ‘feel’ for the pool; but more importantly keep the water clean and clear! (Fig. 4)
