Activity: Collecting Rainwater
Why Collect Rainwater? Collecting rainwater is an eco-friendly and sustainable practice that
helps conserve water, reduce water bills, and benefit your garden or outdoor plants.
Rainwater is naturally soft, devoid of minerals and treatment chemicals, making it an ideal
water source for irrigation and other non-potable uses.
Steps to Collect Rainwater:
1. Select a Collection System: Choose a rainwater collection system that suits your
needs. The most common options include rain barrels, cisterns, and roof gutter
systems.
2. Gather Materials:
Rain Barrel or Cistern: Purchase a rain barrel or cistern designed for rainwater
harvesting. Ensure it has a tight-fitting lid to prevent debris, insects, and
evaporation.
Downspout Diverter: Install a downspout diverter or a rain chain to direct
rainwater from your roof's gutters into the collection system.
Filter and Screen: Attach a filter and screen to the inlet of your collection
system to prevent leaves and debris from entering.
3. Position the Collection System: Place your rain barrel or cistern under a downspout
that receives a good amount of rainfall. Ensure it's stable and level to prevent tipping.
4. Install an Overflow System: If your collection system fills up quickly, install an
overflow system that directs excess water away from your home's foundation to
prevent flooding.
5. Maintenance: Regularly clean the gutters and filters to ensure debris doesn't clog
the system. Clean the inside of the collection system as needed.
Benefits:
1. Water Conservation: Collecting rainwater reduces your reliance on municipal water
supplies, especially during dry spells or droughts. It's an excellent way to conserve
water resources.
2. Cost Savings: Using rainwater for outdoor purposes like watering plants, washing
your car, or cleaning can lead to lower water bills over time.
3. Garden and Plant Health: Rainwater is free from the chemicals found in tap water,
making it healthier for your garden and plants. It provides essential nutrients and
promotes better growth.
4. Environmental Impact: By reducing the demand on municipal water supplies, you
contribute to lower energy usage and greenhouse gas emissions associated with
water treatment and transportation.
5. Educational Value: Collecting rainwater is a practical way to educate yourself and
your family about water conservation and sustainable living practices.
Considerations:
1. Local Regulations: Check local regulations and restrictions on rainwater harvesting,
as some areas may have guidelines regarding the size of the collection system or how
the harvested water can be used.
2. Mosquito Control: To prevent mosquitoes from breeding in your collection system,
use tightly fitting lids and screens. Consider adding mosquito dunks or granules to
the water to kill mosquito larvae.
3. Winter Precautions: In areas with freezing temperatures, drain the collection system
before winter to prevent damage from freezing water expansion.
4. Quality of Roof Material: The quality of your roof material can affect the quality of
harvested rainwater. Roofs with lead or asbestos materials may not be suitable for
rainwater collection.
In conclusion, collecting rainwater is a simple yet effective way to reduce water wastage, save
money, and contribute to environmental sustainability. By following the steps outlined above
and taking the necessary precautions, you can harness this natural resource for various
beneficial purposes while minimizing its impact on the environment.
Other activities which can be performed at home are:
1. Use a Broom: Instead of using a hose to clean driveways and sidewalks, use a broom
to sweep away dirt and debris. This can save a substantial amount of water.
2. Turn Off Faucets: When brushing your teeth or washing your face, turn off the
faucet while not actively using the water. This simple habit can save gallons of water
each day.
3. Shorter Showers: Try to take shorter showers. Consider using a shower timer to
remind you to keep your showers within a reasonable timeframe.
4. Collect Cold Water: While waiting for hot water to reach the faucet, collect the cold
water in a container. You can use this water for other purposes like watering plants or
filling pet bowls.
5. Only Run Full Loads: When using the dishwasher or washing machine, make sure to
run full loads to maximize water efficiency. Many modern appliances also have water-
saving modes.
6. Mulch and Soil Amendment: In your garden, use mulch to retain moisture and
amend the soil to improve water retention. This reduces the need for frequent
watering.
7. Xeriscaping: Consider xeriscaping your landscaping by using native and drought-
resistant plants. These plants require less water to thrive.
