You also lubricate the pipe and gasket with liquid dish soap. If you don't file the ends, you'll never slide the pipe into the rubber gasket. You also need to use a coarse file to taper the cut ends of any pipe. You need to keep the pipe clean of all sand and dirt when you work with gasketed fittings. You do this so it's easier to get a drain-cleaning snake through the pipe if it ever gets clogged. If you need to make a 90-degree bend underground, you should use two 45 bends and put a 1-foot piece of pipe in between them. All underground bends need to be 45 degrees. This is a gasketed 45-degree SDR-35 fitting. If you have hard clay soil, or rocky soil, you can use an electric hand-held demolition hammer tool to dig a trench. The fastest way is to rent a trenching machine from a local tool rental. I usually dig a trench about 12 to 14 inches deep for downspout drain lines. Some local governments or agencies have no rules or regulations. Sometimes you have to pipe this water to special underground storm sewers or above-ground channels. Urban Storm Sewersīefore you proceed with any work, you should check with your local government to see if they have special stormwater rules and regulations. It's far beyond the scope of this column. The entire water-rights issue on private land in the Western USA is very complex. If you collect the rainwater and then use it to water plants, drink and then put back into the earth via your septic system, that water never makes it into the river and then down to the large dams.Ĭontracts negotiated decades ago count on the water making it to the dams. The issue with harvesting rainwater is that it lowers the cubic-feet-per-minute of flow in the major rivers. The stored rainwater can then be used to help irrigate plants that otherwise would have enjoyed the drink before the house was built.Ī simple phone call to your local town office will allow you to discover if you're permitted to harvest rainwater. If the storage is above-ground and placed at the highest part of the lot, drip irrigation piping can be extended from the water storage. If you're permitted to collect and store rainwater, this water can be easily collected and piped to above or below ground plastic barrels or tanks. The water also makes electricity that's sent to tens of millions in southern California and other parts of the Southwest. The water held back by this dam is used to irrigate crops grown for many people in the USA. River systems that feed into the Colorado River are affected by this because the water in this drainage basin eventually flows to and through the Hoover Dam. Laws passed decades ago often prevent homeowners from harvesting and storing water that falls on their land. I regularly visit the Southwestern part of our great nation and am somewhat astonished that stormwater is not collected and stored by homeowners that live in this arid area. Read another column of mine about downspout drain lines that shows you how much water can come off a roof in as moderate rainfall. Heavy rainfall on an average-sized roof can produce hundreds and thousands of gallons of water that spew from the different downspouts located around the house. Often these homeowners are plagued with water seepage into basements or crawlspaces and it's no wonder. I can't tell you how many houses I see where the downspouts empty onto a splash block at the base of the foundation.ĬLICK HERE to get FREE & FAST BIDS from local landscapers who can install downspout drain lines.
