Kohima: Nagaland’s waste management infrastructure is faltering. The state government admitted to the National Green Tribunal that the Faecal Sludge Treatment Plant in Kohima and the Sewage Treatment Plant in Dimapur face severe operational fouls. These details emerged in a compliance report covering the first half of 2026.
Kohima’s 90 KLD plant at Meriema is dead. Power cuts forced the closure. The facility owes a monthly transformer rental fee of 80,000 rupees. The state committee report noted the plant remains non-functional despite most machinery being in good condition. The committee recommended paying the outstanding electricity bills and consulting engineers about replacing the 400 KVA transformer. Staffing is another hurdle. The plant needs five operators, plus twelve more people to run six idle cesspool vehicles. Those suction pumps also need upgrades.
The state government is moving to fix the mess. It is pushing ahead with thirteen additional plants with a combined capacity of 210 KLD. These projects should finish by November 2026.
Dimapur’s plant is also hurting. Monsoon damage from 2025 crippled the site, causing untreated sewage to pour into the Dhansiri River. The state confirmed that one sewage pumping station is back online. This allows the plant to treat roughly 6.7 MLD of sewage, a fraction of its 18.4 MLD capacity. The Nagaland State Disaster Management Authority released funds to fix the rest of the damaged gear. Officials stated: "The remaining two SPSs and associated interception and diversion works will be restored on priority after the monsoon, subject to receding water levels and the availability of safe working conditions." Workers must wait for the waters to drop before they can return the plant to full capacity.
