Ways to Install Rainwater Tanks

Rainwater tanks are an eco-friendly device used to store rain water runoff collected by the gutters on your roof. During a half-inch rainfall, a 50-gallon rain water tank can fill up. This water is safe for outdoor uses such as watering gardens and lawns, washing tools or keeping compost bins moist. Storing rain water reduces your domestic water bill and city's water demands and also helps the environment by conserving water. Rain water tanks are available for purchase at your local garden center; alternatively, you can modify a plastic drum to serve as a rainwater tank system.

Instructions:
1. Clean the rain water tank with a mixture of 1/8 cup bleach and 5 gallons water.
2. Drill a 15/16-inch hole near the bottom of the rain water tank for the drain hole, and insert a 3/4-inch spigot. Make sure the hole is far enough off the ground to attach a garden hose or fill watering cans.
3. Lay a secure cinder block foundation underneath the downspout next to your house. Layer blocks in a crisscross pattern if more than one layer is needed for added support.
4. Place the rain water tank on top of the foundation.
5. Cut the downspout with a fine-toothed hacksaw, leaving enough length to allow the downspout to reach the top of the rain water tank.
6. Attach one end of the flexible downspout extender to the downspout previously cut and the other end to the opening on the top of the rain water tank. If the tank does not have a hole in the top, drill a hole large enough to insert the downspout extender.
