Water from the workshop roof feeds into a large tank. On the backside of the tank there is an overflow pipe that runs to a drainage ditch. The outlet pipe seen on the bottom front, underground back beneath the tank & thru the wall into the workshop to a small water pump. The pump feeds three outlets: a spigot, to run a hose to my drill and tile saw (and outside hose watering as well), plus two sinks: one sink inside the shop (I'm replacing the faucets, so you won't see them in the
photo), and another outdoor utility tub style sink next to a potting bench. It works fantastic! 2 problems: 1.) I need better filtration before water enters the tank, (I'm only using a fine mesh paint filer now), and 2.) If I don't cycle water fast enough, algae builds up. I'm told adding chlorine will help, plus blocking sunlight from the tank will help. Would love any additional insight or tips on this. This project wasn't built to look pretty - it's on the back side of the workshop and not visible from the house, the pool or any neighbors.
My tank, along with a water pump, provides water pressure for an indoor sink, an outdoor sink, and a spigot for a hose to feed my water-fed tools (drill and tile saw). Absolutely LOVE it. Need to 1.) improve my filtering process(es) before water enters tank, and 2.) adding clorine to tank when water turn-over is slow to prevent algae growth.
