Nagaland prioritises water sustainability with greywater management

Published on May 19, 2025

KOHIMA — Chief Minister Neiphiu Rio said on Monday that Nagaland is prioritising water sustainability through the implementation of greywater management in 988 villages across the state as part of the Swachh Bharat Mission.
In an update shared on X, Rio informed that the Department of Public Health Engineering is spearheading the Greywater Management programme.
“By recycling used water for agriculture & sanitation, it is conserving resources & driving a more sustainable future,” he wrote.
The post explained that greywater management is the process of collecting, treating and reusing wastewater that comes from household sources (excluding toilets) like sinks, showers, bathtubs, washing machines and dishwashers.
It clarified that while this type of water might contain soap, food particles, hair, and dirt, it is generally less contaminated than blackwater.
It further underscored the benefits of greywater management, including sustainable landscaping, lower utility bills, and the promotion of eco-friendly building designs.
The chief minister’s post underscored the system’s importance in Nagaland due to the state's high rainfall but often irregular water supply in many towns and villages.
"Many households in Nagaland rely on spring water, rainwater harvesting, or tankers, making water conservation essential. Terrain makes centralised sewage treatment challenging—ideal for decentralised greywater reuse,” it stated.
