use a 55 gallon drum to capture and store rain water.

FAQ Continued

 Why should I harvest rain water?

 Free source of water!  Rainwater is better for plants than chlorinated tap water.  Reduce stormwater runoff  Reduce pollution levels downstream

SLIDE 4

Basic Water Harvesting System

 Gutter along the roof with

a leaf screen

 Smaller mesh filter

between down spout and gutter tank

 Good connection to tank  Properly sized storage tank

with overflow and drainage valves

 Elevate tank 3’ to 4’ for

good gravity flow

SLIDE 5

Rainwater flows off a roof, through a downspout, and into a barrel or cistern where it is stored for future use. Rain barrel: 55-80 gallon Cistern: 200 + gallons 1000 sq ft roof + 1 in rain = 600+ gallons

How much water?

SLIDE 6

 Irrigation (outdoor gardens and indoor houseplants)  Car wash / bike wash  Pet wash  Rinsing gardening supplies  Emergency water to flush toilets  So much more!

What can I do with the water?

SLIDE 7

 Roof material  Screen  Mosquitoes  Overflow  Linking  Irrigation  Pump/pressure or gravity  Maintenance

Considerations

Not a source of potable water!

SLIDE 8

Metal Roof:

 Safe for all factors tested

Asphalt Shingled Roof

 A bit high in Copper,

Manganese, and Iron, but well within safe levels for plants.

 pH somewhat acidic – 6.5

 (6.5 – 8.0 is recommended)

Bringing your barrel home:

 Make sure there’s room in

your car!

 What corner of the house?  Elevation?  Where will you be watering?  Retrofitting your

downspout.
