I asked awhile back about using UV lights to sanitize our communal pool.
It has now been done. Our pool is about 120,000 gallons. The water for it comes from wells that reach down to hot water (about 130° F). The pool has two large sand filters but no heating system. 3 to 4 times a week the pool is lowered to allow room to add hot water from the wells to heat it. The pool is kept at a temperature from 86° to 102° F. Some chlorine is added to the pool. The water is fairly mineralized and the pH is over 8. In the past we have had problems keeping the pool clean.
So the following changes were made to our system to try and improve the water quality;
2 Spectralight UV lights were installed after the filters, 2 chlorine dispensers-Interwater Clorador Model 1W-0680, and 3 new 2 speed Hayward pumps were installed. It has been 2 months now and the pool is often quite green and cloudy but may be sanitary. Chlorine levels in the pool are now from nil to trace.
The water that was drawn down from the pool went to cisterns where is was stored for watering. Any excess ran down the street.
Our water supply for the homes in our subdivision comes from the same hot water wells. It is stored in several cisterns from where it is sent to the 300 some properties at various times. Now some of the water drawn down from the pool is sent to these cisterns that supply the homes in our subdivision.
Does anyone have any thought or suggestions about this arrangement?
