What is the overall annual cost of water on a typical home catchment system?
For example, an average residential catchment system will require one UV bulb annually at a cost of $89. each year. Sediment filters need to be changed monthly, so you will need 12 sediment filters at a cost of $3.95 each. Carbon filters need to be changed quarterly at an average cost of $9.99 each. Add the cost of electricity to run a pump from the tank to your home, an average cost of $10. per month. The overall operating cost of a complete rainwater catchment system can be as little as $296.36 per year or $24.69 per month, for a typical Hawaii home. This compares with an average municipal water bill of $40. month at today’s pricing.
