Water Conservation

Conserving water in your school garden is an easy way to help
the environment! Did you know that less than 1% of the water on
Earth is accessible for human consumption? Please make choices
that conserve water in your school garden by choosing native
plants, collecting rainwater and irrigating in the early morning
hours to prevent evaporation loss.

Hand Watering – This option should be used to provide additional
water to plants, it should not be used as the primary watering
method for school gardens.

Drip Irrigation – This method keeps water usage to a minimum,
though maintenance of the system will be required by the school.

Rain Barrels – Capturing rainwater to use for flower or butterfly
gardens is an excellent way to conserve water. Rain barrels must
have secured, lockable covers to prevent accidental drowning,
to limit access to animals, and avert mosquito breeding. Water
captured by rain barrels may NOT be used to water edible gardens
or fruit trees. If the plan is to use rain barrels, the following
conditions must be met:
• A roof from which to collect water and an appropriately sized
downspout for the size of the container is necessary.
• Rain barrels must be arranged so they are not mosquito
breeders.
• Rain barrels must be covered and secured at all times.
• Check the barrel or cistern for leaks, cracks, sediment build-up
or debris.
• Rain barrels must be properly supported and secured to resist
hurricane wind loads.
• Rain barrels must be placed on a square concrete base.
