Water Recycle
Recycling water the natural way
Natural water treatment at Siemens facility in India
In a densely populated country like India, water is a very precious resource. Home to approximately 16 percent of the world’s population, India has but four percent of the planet’s water reserves. With this in mind, the location management of Siemens Real Estate in Kalwa, India and EHS opted to implement a wastewater treatment system that would, for the most part, regulate itself – much like a natural wetland. “Environmental, health and safety issues are taken very seriously at the Kalwa site. The decision to install a natural water recycling system here was no coincidence,” says Veerabhadrapp Chaugula, Location Manager at in Kalwa.
A complete cycle
Rather than high-tech, the facility’s water recycling system relies on an ecosystem consisting of plants and microorganisms that eliminate harmful substances from the wastewater. “It works kind of like a swamp or marshland,” as Veerabhadrapp Chaugula explains. The water is treated mechanically and biologically using a cascade of 32 gravel-filled basins that filter out particles in the water. Plants supply oxygen while their roots aerate the gravel bed. Organic substances are decomposed into carbon dioxide and water by bacteria. Finally, the water is channeled back to the administrative building, garden facilities and rest rooms, completing the cycle.
Artificial wetland recycles wastewater from Siemens facility in India
The wastewater treatment system of Siemens Real Estate in Kalwa, India, for the most part regulates itself like a natural swamp.
Ingenious but spacious
Requiring only pumps and flow rate meters, the artificial wetland recycles wastewater from four sub plants and an administrative building. Also, it does not require continuous monitoring as in the case of conventional sewage treatment plants. However, what it does require is space – an area of 1,000 square meters at the Kalwa facility. But even that has its
