    Question Rain Water: reclaimation & irrigation

    Looking for a solution to capture downspout rain water into one large (200-300 gallon) or multiple smaller underground plastic tanks during rain events. Access to the water needs to be obtained using a pump and hose system to water 150+ shrubs, located around the exterior of the house. The underground plastic storage tanks need to be drained in the winter months (November thru March) due to freezing temperatures. There also needs to be some type of diverter to route water away from the tanks when full or during the winter months if there is an unexpected winter rain, instead of snow. The terrain around the home has grade elevation changes of between 4 to 6 feet to assist in draining and "moving" the water with gravity flow.

    I think I would avoid the plastic tanks and put in a system like they installed at the Cambridge project.

    We're considering the same thing. We live on a higher grade than our neighbors, and when we water we have a lot of run off. We haven't spent much time working out the kinks in our sprinkler system because of it. We're going to use 2 additional systems. We're going to put the water run off containment system in the front yard and tie it to the re configured sprinkler system then we're going to replace our septic system to care for our rose garden then we'll use the current system to control the water for our garden and play yard but it will need to be filtered for contaminants since it's in areas that our kids frequent.

    Why avoid plastic tanks ? Plastic and fiberglass tanks are used for underground gasoline / diesel fuel storage . They are obviously durable enough and easier to install and remove .

    because the o.p. is concerned about freezing in winter.

    Eventually a plastic tank will break if the ground freezes.

    WAY too many variables involved for that statement to be considered valid .

    There is all kinds of information on the internet for your info. I see no problem with burying your tank if you wish. Also, remember, if you place it below the frost line it will never freeze due to the ground tempeture. Your container needs to be either reinforced to prevent the ground collapsing around it.

    Check out http://www.cleanairgardening.com/rainbarrels.html for stuff. Process of elimination. Good luck.

    Pleae tell me how you learned specifics on how to do the above things you have planned. I'd love to do that but live in LA. where graves are often above ground due to water table being so close to ground level so buried stuff floats to surface. Thanks, Charleen
