Due to the ever-increasing population, our resources are stretched to the limit. This includes water, which is why many people are now more consideringrainwater harvesting systems for industrial buildings and residential areas. To make this proposition cost-effective takes an innovative approach.
Whether you are installing a commercial rainwater harvesting system due to strict rules or for sustainability reasons, make sure you do your homework. Considering all the inputs for a system design will help you down the road.
Considerations for a rainwater harvesting system:
Tank
The tank that you are using to store the water plays a crucial role. It may seem to be a minor decision, a tank that is too small will be inefficient. One that is too big is wasted money. To find the right size tank, look at the following:
- Building Size
- Amount of Rainfall
- Water Demand
- Budget
These factors can help determine the optimum tank size.
Location
The best place to keep the tank for an industrial rainwater harvesting systemdepends on the site. Below-grade tanks are good for properties with limited space inside the building or outside, above-grade. Above-grade tanks make work better for properties with a high water table, or limited space available below-grade.
Drainage System
There is no point in storing rainwater if can’t direct the flow to the tank. A Civil Engineer can help determine the best layout of the drain lines in order to feed the captured water to the cistern by gravity. To reduce maintenance on the tank, important to design in a pre-filter upstream of the tank.
