Industrial Rainwater Harvesting: A Sustainable Option

Industries use a generous amount of water in their different operations and some, such as beverage and textile use more water compared to their counterparts. It becomes essential for these industries to look for a more sustainable solution.

Rainwater harvesting system for commercial buildings can offer a strategy for industrial buildings to reduce their environmental impact and save money. Collecting, storing, filtering, and reusing the rainwater is the most traditional technique with plenty of benefits. It can mitigate the issue of water shortages and help to prevent flooding.

What is Industrial Rainwater Harvesting?

The idea behind rainwater harvesting is to collect the rainwater, store it and use it for various non-potable applications after it is treated. The only difference between an industrial rainwater harvesting system and domestic rainwater harvesting system is their size. As industries have relatively more consumption, rainwater harvesting system for commercial buildings involves large tanks for storage and industrial-grade processing equipment. Studies show that a rainwater harvesting system can meet much of the water requirements of a typical commercial building.

The main aspects of rainwater harvesting system for commercial buildings:

Before deciding on installing an industrial rainwater harvesting system, the following aspects must be considered:

Average Rainfall

The purpose is to collect the rainwater. Hence, the system will prove beneficial if only there is enough rain in that area. Collect the data about rainwater to get an estimate.

Demand

The next thing to consider is the demand for non-potable water on day-to-day basis. While some industries require more water to meet their daily requirement, some can do with lesser quantity.

Sizing

Keep in mind the available space for a cistern, either above-grade, below-grade or inside the building.  Furthermore, select the size of the tank considering rainfall amount, demand and roof size.

Design and Installation

The next aspect is to design an efficient and cost-effective system. The water should be treated to a level that is safe for non-potable applications in a public space.

To design a system that incorporates the above considerations, partnering with an expert in the field is always vital. If designed properly, an industrial rainwater harvesting system provides an opportunity to reduce environmental impacts and save money.
