M19 - Rainwater Tank

Creating your own water supply brings great benefits and does pay off. This collected water can be used for toilet flushing, car washing, garden maintenance, and other private and business use. Implementing a water tank reduces small urban floods and reduces the need for dams, which can potentially endanger delicate areas of the ecosystem. To bring rainwater to its potable condition is relatively easy, seeking the right advice from the right source can easily eliminate some concerns you might have about drinking the harvested water from dirty roofs Issues such as mosquitoes, bacteria growth, chemical, and organic roof deposits can be overcome and render the water ready for drinking. The collected rainwater must meet standards set by the local health authorities. Consult with your water tank or water filtration expert for the correct setup and filtration requirements. Temperatures are a contributor to better water quality and need to be addressed especially if your roof is black or darkly colored. Another thing to consider is whether your tank should be above or underground.

Example: When 25 mm of rainfall is collected 2 times on a 10m x 10m roof means that we can collect 5'000 liters of water.
