Harvesting rainwater can lead to a significant decrease in the consumption of mains water around the house. This translates to lower water utility bills for the homeowner.

A rainwater tank is the heart of any rainwater harvesting system. Therefore, there is great importance attached to making the right choice of tank. Below are a few things that homeowners should know in preparation for the all-important purchase.

Material Matters

Homeowners need to understand what to expect with each different tank material in order to make an informed decision.

Metal tanks are commonly used for residential rainwater harvesting. These tanks can be made of various metals including stainless steel and aluminium. Aluminium tanks are less preferred due to the harmful nature of aluminium metal sediments that may be deposited in the harvested water over time. Stainless steel tanks are preferred for their superior ability to resist rust and corrosion.

Concrete rainwater tanks are a great option for homeowners working with little space for tank installation. This is because concrete tanks are commonly installed underground, thereby eliminating the need for additional space to allow for tank installation.

Fiberglass rainwater tanks don't come cheap. They are preferred for their ability to stand extreme temperatures and are commonly installed above ground level.

Legal Matters

As absurd as it may sound, there are legal considerations to be made when looking to invest in a residential rainwater tank. A large number of homeowners are often unaware of the legal aspects of rainwater tank acquisition. For example, there are bound to be rules and regulations that govern rainwater harvesting and the use of rain water for drinking. The tank installation project may also have to meet certain requirements aimed at preventing and/ or control the breeding of mosquitoes around the residential area.

Similarly, there may be regulations about the use of water pumps with rainwater tank accessories. Such regulations commonly address the problem of noise pollution as a result of pump operations. Because these regulations differ from one jurisdiction to the next, it is important for a homeowner to consult the relevant authorities before acquiring a tank, pump, or related items.

Space Matters

Lastly, homeowners need to have the available space in mind when choosing between different types of rain water tanks. Homeowners working with limited space are advised to settle for slimline rainwater tanks. These tanks are specifically designed for installation in narrow and often awkward fitting spaces.
