Recycling of wastewater

The Orchid in Mumbai is India's pioneering eco-hotel. One initiatives is to eliminate wastewater discharge by treating and recycling 100% of water onsite. The hotel uses rotating biological contactors (located on the roof) to treat grey and black wastewater. The system uses a biological film coated with bacteria, which removes oxygen and nutrients necessary for the growth of harmful microorganisms. Other particles and pollutants are removed by additional filtration and the resulting water is used to irrigate the hotel gardens or discharged to the sewer. There are additional initiatives for waste and energy.
