Think about how much water your fire sprinkler system is capable of using, now think about how many times per year the system is tested – that can be a lot of water! If your system is tested four times per year, it could add up to 15,000 gallons per stand pipe. Capturing this water for re-use can be done with a holding tank and particulate filtration, as the water will likely have been standing for many months. After the water has been filtered, it can be used as needed for irrigation, cleaning, or other purposes. The best part is that you’ve already paid for it, so any collected water will be a benefit to your water bill.
