Do you use roof run-off to fill your ponds? Do you filter it first? How?
Can I safely use roof run-off directly into my swimming pool-soon to-be-pond to top off the water lost to evaporation? Right now the pool water is pumped through a sand filter daily which is back-washed every week.
The runoff would be screened to remove leaves and twigs, then through a (presently small) skippy type of filter tub to catch smaller grains/granules and some petrochemicals and bacterias including coliforms from the asphalt roof. As this is direct roof run-off, the water will be moving fast. ThereÃ¯Â¿Â½s no gravel bed right now to run it over, it would be sent to the pool. I donÃ¯Â¿Â½t want to pollute that water, or the pond, when I finally transform it to a pond, several months in the future.
