In Portland, the make you do it. In my area we pipe it back to the break tank because our water purveyor charges lots of money for using the water

There are a lot of variables (like how long they do each flow, etc) that will impact how much water is saved or used. I don’t think there is enough consistency to make it viable. You would have to pick a time of flow and meter the exact flow rate. You also need to realize that the test is to evaluate if the pump is running at capacity and not to give you numbers for design. The most restrictive place I have been to for discharge is the Coast Guard Academy in New London,CT. You can’t discharge on grass and only in to certain drains. This is more of a problem for relief valves as both pumps have flow meters going back into the suction. I’m not sure is these restrictions are true at other military facilities because I haven’t been on other bases for work in a while.

I’m wondering if anyone here has ever done a green points calculation for the benefit of having a flow meter on a fire pump and rat racing back to suction rather than waste. I’ve heard many talking of this and how conscious they are in our effort to save water but I’m wondering if anyone has ever submitted applications, calculated savings, or presented evidence. I’d also be interested in local or regional purveyor requirements on waste, reclamation and disposal. Go Red Sox.
