Several initiatives have been taken up in Prayagraj to ensure zero liquid discharge (ZLD) into the Ganga river. This includes treatment of wastewater from around 150,000 toilets including soak-pits, fibre-reinforced plastic units and mobile units on a daily basis. In order to ensure efficient sanitation services, a QR code-based surveillance system has been set up to ensure real-time maintenance. Also, technologies such as jet spray cleaning technology and eco-friendly chemical solutions are aiding in the maintenance of hygiene and odour-free sanitation facilities. For an effective liquid waste management, 94 suction machines have also been installed.
