Rainwater is pure gold that falls from the sky. Harvesting this clean and clear resource can trim your utility bills and minimize your environmental impact while reducing strain on regional water treatment facilities. When properly designed and installed, a rainwater collection system is an investment whose dividends benefit the entire community. The following are seven tips that will help you squeeze every last drop of value from your rainwater collection strategy.
- Determine Consumption & Availability
Rainfall is variable, and the amount of rain that falls in your area may not be sufficient to meet your needs. You must calculate the water consumed by your lifestyle and landscaping needs. For example, water consumed by dishwashers, toilets, showers, sprinklers, etc. Next, you will want to determine whether regional rainfall is sufficient to meet these needs. As a general rule, you can expect annual rainfall to meet about 50% of your water needs. - Consider Your Roofing
Shingled roofs can leach toxins into rainwater making it unsuitable for drinking. If you want to use your water for cooking, etc., consider replacing your roof with terra-cotta, slate, wood shingles, or concrete. - Choose Barrels Carefully
Choose barrels that are sufficient in size and construction to meet your collection needs and any freeze/thaw cycles inherent to your climate. Barrels should be opaque to minimize algae growth and comprised of materials (either wood, metal, or ideally, plastic) that won’t leach toxins into the water. - Regularly Clean and Cover Your Barrels
Position your barrels so that you can access and clean them every six months. Once every two years, your tank should be thoroughly de-sludged. This helps to inhibit the growth of bacteria and ensures your water remains fresh.
It is also advisable to conduct monthly tank inspections to ensure that filter screens, covers, and locks are functioning properly and preventing access to the tank by children, insects, pets, and other wildlife. If any damaged seals or locking mechanisms are discovered you will want to replace these without delay. Keeping your system closed off is essential for keeping the water clean and free of biological pathogens and insect infestations. - Shield and Clean Your Gutters
Installing gutter shields and regularly cleaning the gutters on your home will help limit sludge buildup within your rainwater collection tanks. If you want to use your rainwater for human or animal consumption, you may also want to replace any soldered seams with rivets as soldered seams can leach lead into the water supply. - Be Careful When Installing the Spigot
Screw your spigot down so that it is hand tight. This helps prevent stripping of the threads and damage to the plastic, wood, or metal of the rainwater collection barrel. If you screw the spigot down too tight, the damage you create can cause leaks that negate your efforts. - Stay in the Grey
Safely using rainwater for drinking requires significant investment and training. For this reason, most homeowners opt to use the rainwater they collect for showers, dishwashing, clothes washing, and irrigation. Using your water for these purposes will significantly reduce your water consumption without putting the health of your family at risk.
Rainwater collection systems are worth their weight in gold. Using this free, 100% natural resource helps reduce your utility bills and minimizes your impact on the regional water supply. Collecting rainwater is an eco-friendly solution that is guaranteed to help beautify your landscape while adding a little extra padding to your monthly budget. A small investment of time and resources is all it takes for you to reap these rewards season after season.
