The lifespan of Meghalaya’s Umïam dam, one of the oldest hydroelectric power generation in the region, will be reduced by 41 years. 
Constructed before the creation of Meghalaya in the early 1960s, the Umïam dam stores water for hydroelectric power generation. 
“The life span of the dam was designed for 100 years, the MeECL (Meghalaya Energy Corporation Limited). The life of the dam will end in the next five years by 2024 due to heavy silting and pollution caused by heavy siltation,” Meghalaya Assembly Committee on Environment, S.K.Sun said. 
The life of the Umïam dam is estimated to be 100 years which should be by 2065. 
Sun, who inspected the Umïam dam with committee members, urged the public to take care of the dam especially the two rivers – Umkhrah and Umshyrpi in Shillong city by not throwing waste indiscriminately.
Studies related to assessment of siltation of the Umïam dam was conducted in 1990 by M/s Water and Power Consultancy Services (Wapcos) and by M/s Tojo Vikas International Private Limited New Delhi in 2004.
“It is alarming that the life span of the dam is ending by 2024. What will happen after that? Therefore all stakeholders should be concerned and put our heads together in saving this dam,” Sun said. 
During the inspection, the Assembly committee found that silt deposits in the dam was very high and all types of waste including plastic waste carried by the highly polluted Umkhrah and Umshyrpi rivers accumulated in the dam.
