When we were planning for Hotel fifteen years back, I had the idea of reusing the sewage water. At that time, the cost of treatment was very high, and the recovery also was significantly less. Fast forward, I had no idea in my wildest dreams that I would be putting up a Sewage treatment plant for our family-run hotel in Palladam. Palladam is a small town near the famous Tirupur known for its banian manufacturing. Palladam is an arid area with significantly less rainfall, and the source of drinking water is from the Government and water tankers.
1st Case Study
I always wanted to save water and reuse the water, so we decided to put a sewage treatment plant. The plant helped us in more than two ways; one thing was we kept water, and the second there was no proper drainage system in Palladam, and the sewage treatment took care of it.
OxyO’s sewage treatment plant recovers almost 98 % of the water we use for multiple purposes. We are using the treated water for Gardening, which is nearly 30% of the water. Provisions for flushing has been made, which is around 30% of water usage. In total, 60% of the water is reused. The balance water is safely let in the drainage.
2nd Case Study
The second case study is of a Textile plant where they had a very od conventional treatment plant.
The textile plant near Sultanpet in Tamilnadu had huge water problems, as they were always short of water. The company had to purchase water for their staff at a whopping cost of 7 lakhs per month as their wells and water supply was not enough for their company staff of approximately 2500. They were consuming close to 3 lakh litres, and they had to buy from outside, costing them dearly.
They also had a sewage treatment plant that was almost 10 years old and was not operational. As their multiple pumps were breaking down often, and the company had to shut down the plant. We visited the plant and collected the details of the existing plant’s drawing and equipment. We revamped the plant, and now the treatment plant can treat 150 KLD of water.
The recovered treated water is almost 98% and is used for multiple purposes. They have lots of garden area, and nearly 30% to 40% is used for Gardening. Then the balance water is used for flushing toilets, thus saving them almost 3 Lakhs of rupees per month.
Previously the sewage water was overflowing, because of that it was creating bad odour, and the water was going to waste. Now the water is safely treated at reused.
From both these case studies, we can conclude that we can become self-sufficient in water by reusing the treated water as more than 95% of water is recovered and reused. The balance water of 5% to 10% can be taken care of by a rainwater harvesting system.
