With the growing impact of centralized water supply on the environment and rising costs to homeowners, many people have or are considering investing in a decentralized rainwater harvesting system.
What is a decentralized rainwater harvesting system? In the simplest form of effectiveness and cost, it is a rainwater tanks on your property, along with a low-cost delivery system (pump).
To get the best from your investment in rainwater tanks, there are several factors to consider.
1. Available space (usually close to your roof downpipes). Given the exceptional potential of rainwater harvesting even in the smallest roof area, the recommendation is always to invest in the largest water tank both to the high ground or space available.
Water storage capacity (capture rain water-free) is the reason most people buy a water tank. It's important to remember that the rainfall is not always consistent. It's best to capture as much of it as possible when it is available.
2. Proposed tank access to the location. To avoid the cost of hiring equipment (e.g., cranes), it is important to consider access to the proposed location of your tank.
3. Rainwater tank will be a part of your home, so it's important to consider the visual. Most of the tanks on the market today (especially polyethylene/plastic and steel tanks) are available in assorted colors. These colors are often the exact colors used in other parts of the house (e.g., guttering, fencing, and roofing).
