My sump generates a lot of output during some weeks. Enough that I need a better plan than dumping into the grass and gravel driveway downslope from the house. My first step in improving my driveway is calculating the amount of water I am dumping into it. What is the easiest way to measure? The 2 inch discharge pipe is about 18 inches off the ground. I guess I could dump the water into a kiddy pool and measure the amount of water in it after a 24 hour period. That leaves me with a kiddy pool I'd have to throw away in a month. I would prefer a method that allows me to measure into the future.
Is there a simple flow meter for a 2 inch pipe that will measure the amount of water flowing through it? I have found some, but they appear to be industrial grade and industrial priced.
I could estimate the volume of water discharged when the sump cycles on, and then count the number of times the sump runs. But how would I count the number of cycles?
