is an ancient method of conservation that’s making a comeback. Catching
rainwater in a barrel can save money on your watering bill and it
obviously helps conserve watersheds.
the avid gardener, this could be a brand new challenge. Using barrels
or water tanks to catch and store rainwater for the hotter months could
be a refreshing way to irrigate the garden.
Austin, Texas, city officials are offering up to $500 on the cost of
installing a large capacity rain harvester. Ranchers and farmers
in Sun Belt states have long relied on rain harvesting to get through
the scorching summer months. Now it seems that the general public is
becoming in tune with this old way of conserving water.
process of gathering rainwater and using it for landscaping is very
simple. Rainwater is gathered by gutters and downspouts, and then it
collects in a larger storage tank. Micron filters can be
used to clean out twigs, leaves, dirt, and other debris. It’s possible
to use this water for drinking as well, but that’s another story.
Now to use this water for landscape irrigation
you’ll have to upgrade the holding tank with a pump. A full tank that’s
10ft. tall only has 5 PSI (pounds per square inch). To use a
drip-irrigation system you’ll need at least 15 PSI. Adding a water well pump will pressurize the tank and make it usable for landscape irrigation.
