Introduction
Rainwater collection is an excellent way to conserve water and reduce your dependence on municipal water supplies. One way to collect rainwater is by repurposing old water tanks. Repurposing old water tanks is a creative and environmentally friendly way to collect and store rainwater for non-potable uses such as watering plants, washing cars, and flushing toilets. In this article, we’ll explore the benefits of repurposing old water tanks for rainwater collection and provide a step-by-step guide on how to do it.
Benefits of Repurposing Old Water Tanks
Repurposing old water tanks for rainwater collection can have several benefits, including:
Environmental Benefits: Repurposing old water tanks reduces waste and helps to conserve natural resources.
Cost Savings: Repurposing old water tanks can save you money by reducing the need to purchase new tanks.
Increased Water Security: Repurposing old water tanks for rainwater collection can provide you with a reliable source of water, even during times of drought or water scarcity.
Reduced Stormwater Runoff: Repurposing old water tanks for rainwater collection can help to reduce stormwater runoff, which can cause erosion and flooding.
Improved Water Quality: Repurposing old water tanks for rainwater collection can help to improve water quality by reducing the amount of pollutants and sediments that enter waterways.
Step-by-Step Guide to Repurposing Old Water Tanks
Repurposing old water tanks for rainwater collection is a relatively simple process. Here’s a step-by-step guide:
Inspect the Tank: Before repurposing the tank, inspect it for any signs of damage or corrosion. Check for any holes, cracks, or rust spots that could compromise the integrity of the tank.
Clean the Tank: Clean the tank thoroughly to remove any debris or contaminants. Use a pressure washer or a scrub brush to remove any dirt, grime, or algae that may have accumulated on the tank.
Install a Roof Catchment System: Install a roof catchment system to collect and channel rainwater into the tank. This can include installing gutters, downspouts, and a roof washer.
Install a First Flush Device: Install a first flush device to ensure that the water collected in the tank is free from contaminants. A first flush device allows the first flow of water from the roof to be diverted, taking any debris and contaminants with it, and then allows clean water to flow into the tank.
Install a Screen and Inlet: Install a screen and inlet to keep debris and contaminants out of the tank. The screen should be fine enough to keep out leaves and other debris, and the inlet should be designed to allow water to flow into the tank while keeping contaminants out.
Add a Overflow Valve: Add an overflow valve to prevent the tank from overflowing during heavy rainfall events. The overflow valve should be designed to allow excess water to flow out of the tank while keeping contaminants out.
Install a Pump and Treatment System: Install a pump and treatment system to make the collected rainwater suitable for non-potable uses. This can include installing a filtration system, a UV treatment system, or a chemical treatment system.
Test the System: Test the system to ensure that it is working properly and that the collected rainwater is safe for non-potable uses.
Conclusion
Repurposing old water tanks for rainwater collection is a creative and environmentally friendly way to collect and store rainwater for non-potable uses. By following the step-by-step guide outlined in this article, you can repurpose an old water tank for rainwater collection and enjoy the many benefits that come with it.
