Last week an article was written in the Key West Citizen about how much money could be saved by changing your septic tank to a cistern. It was claimed you can save $1,297.00 in a year with a 1000 gallon cistern. After the FKAA charges the base facility charge, you will pay about one penny a gallon. You would have to empty your tank over 10 times a month, once every 3 days for the entire year, to save $1,297.00. So far this year we have not had enough rain to fill the tank over 4 times. Now I believe the FKAA is using these numbers to justify charging everyone who changes their septic tank to a cistern a flat base facility charge of $65.00 a month. It is my belief that the FKAA wants to punish any one who tries to save water. Ok. With my 750 gallon cistern I kept a float for chlorine tablets used in swimming pools. I used that water to do my laundry then used the water in the garden and I saved 1000 gallons of water a month and $10.00 off my water bill.
