This is actually how we did our grey water irrigation system. I had asked a few months back What size pump do I need to get enough pressure for my drip irrig system to use our stored grey water? (in CA)? I got asked for more details from plumbers in plumber speak They would need to know diameter of pipe, size of weep holes etc and also the guy who said it wouldn’t work (clogs the drippers). The question also got coded as Resolved. I didn’t consider it resolved… no one answered my question. So we figured it out ourselves. It’s working great. Here’s what we did. (Hope the nay sayers and the plumber check this out) For details we bought the original irrigation set-up as a kit from Lowe’s and added more drip spots for additional plants. We have about 200 ft of the black pvc pipe (which I think is 1 inch) and probably 70 drippers set up on 1/4 inch tubing (some on T configurations) . When I originally asked the question we had been watering from storage containers (trash cans) with a 1/6 horsepower pump and a hose. I didn’t have enough water pressure to use a nozzle on the hose and obviously not enough pressure for my irrigation system. Being in CA, I wanted the convenience of the drip irrigation and it is better for my plants ( no splash on the plants, no waste, and deep slow watering), but I also wanted the conservation of the grey water. We only use our laundry water and shower water. I’m not crazy. Sink water would have too many food particles and sewer water is out of the question. Because of the way our rental is set up—our washer drains into a work sink. We have a metal screen sock (you can buy them at Lowe’s) set up on the wasing machine drain tube to catch lint as it goes into the sink. First place we filter. We use a small (auto on) pump to drain the water from the sink and into a large trash can that is for storage. The pump from the sink also filters some, so 2nd place water gets filtered. Our shower water is drained directly from the tub into a small container (because of our distance from the tub to the storage containers) with an auto on pump (1st place shower water is filtered) down pvc tubing into a storage container. The water is pumped from the small storage container (2nd place shower water is filtered) into the larger storage container. So far shower water and laundry water have had 2 opportunities to be filtered, automatically. We have additional storage containers, in case we have an excess of water. We have placed small bricks on the bottom of the storage containers, and place the pumps on the gap between the bricks. It gives the trash a chance to settle to the botom and the pumps don’t suck the trash into the final storage container. All of the storage containers are treated with a fungicide for each full container (your plants will suffer without treating the water) and I occassionaly treat it for sludge. We have had no problem with smell during storage and our plants are healthy. We usually only need to store water about 1 or 2 days. We learned the fundicide treatment is essential. We suffered from a bout of fungas gnats. I also clean the cans about every 2 weeks, to remove the gunk and sludge, but it has been minimal. My irrigation system used to have blow outs even when I was using fresh water. I was using the pressure regulator provided, but it still seemed to blow apart connections. Getting soaked with fresh water is bad enough. I did not want to get soaked with grey water, so I super glued the connections. Seems odd, but it works. I left the drippers unglued, so I can change them out if I find I am giving a plant too much or too little water. At the start of my irrigation system I have added a filter (doesn’t come with the kit, but you can buy it) and a pressure regulator. We have updated the 1/6 horsepower pump to a workhorse 1HP (but cheap and affordabe at Freightliner Hardware) and I can even run my sprinkers now. Again because of where we have to store the containers and where my irrigation system starts, we have a hose that comes off the 1 hp pump and then it is hooked to a short garden hose that goes over to the start of the irrigation system, where the filter and regulator are. Between the hose from the pump and the garden hose that goes over to the irrigation start, I have added another filter. I feel this is very important. Any final bits of lint or gunk are caught in this filter. I change it occassionally while I am running the irrigation system, but have noticed that the filter at the start of my irrigation system is always clean. So I must not be getting trash there. My system is running great and clean. Dripping away and conserving water and my time. I have a few plants off in the boonies that I hand water with recycled water while I am running the irrigation system. I will use the left over 1/6 hp pump and a hose for my hand watering with the recycled water. We invested about $300 in the materials that we use for this system, including trashcans, pvc
