type of pool requires a lot more construction techniques but
is the ultimate in luxury. The water overflows from the pool
into a grate, as the grate is the same level as the deck this
creates an effect of continuity which makes the pool look
larger than it is. Once the water has overflowed into the
grate it is then taken to a balancing tank, this stores water
from the pool and keeps the water at the same level however
many bathers are using the pool. The tank is usually stored
underground and fitted with float switches to activate the
pump, water is then taken from the tank and through the circulation
system before returning to the pool by the return inlets.
Pool water is normally very high quality, its surface water
is drawn off the pool throughout its perimeter.
