The Brihanmumbai Municipal Corporation (BMC) had decided to install waterless urinals at public toilets near Gateway of India. They do not require water to flush and prevent bad odour. These urinals will save approximately 10 thousand litres of water per day and 70 thousand kilograms of carbon a year.
In each urinal there will be a sealing cake of 150 millimetre thickness, which can withstand 10,000 uses, and costs Rs 2,000.
According to the BMC’s calculations, each flush consumes about 2 litres of water, and the new urinals will save 10,000 litres of water per day. Besides, a flush consumes energy, which will also be saved. This carbon saving may accrue carbon credits to the BMC.
