Focus on increasing storage level of Peppara
With the 75- mld water treatment plant at Aruvikkara anticipated to be commissioned quickly, the spotlight is back on the long-standing need of the Kerala Water Authority (KWA) that the storage level in the Peppara dam be increased.
Increasing the permitted storage level to a minimum of 109.5 metres from the present 107.5 metres is important for the State capital to delight in the full benefit of the 75- mld (million litres a day) plant and to fulfill the ever-increasing water requirements, say KWA officials.
The Peppara dam has a full reservoir level (FRL) of 110.5 metres. Although the KWA proposition is scarcely a brand-new one, it had actually found little support previously since it requires submergence of forestland. The State-run water energy, which has restored its efforts to acquire clearance, remains in the process of filing the application before the Ministry of Environment and Forests (MoEF).
Being built under the AMRUT plan at Aruvikkara, the plant is anticipated to be all set by December this year. This will take the KWA’s ability to pump water to the capital city to roughly 375 mld. However a sufficient reserve storage for the dry/drought months can be guaranteed only if the storage at Peppara is increased to a minimum of 109.5 metres, according to KWA authorities.
“‘ This requirement might not end up being right away visible after the 75 mld plant is commissioned since we plan to briefly shut down the existing 86- mld plant and the 72- mld plant at Aruvikkara for rehabilitation works once the brand-new plant is functional. However the requirement will end up being rather apparent within a year or so when all the plants are up and running,” a senior KWA authorities said.
Moreover, increasing the storage level at Peppara likewise ensures the capital city a buffer supply during droughts. In 2017 the water level in Peppara had actually dipped to such an alarming level that the KWA was required to rig momentary pumping facilities in the Neyyar reservoir to feed the city areas.
The Peppara dam was built for meeting the water requirements of the capital city and its suburbs. The first stage was completed in the 1980 s with a storage level of 104.5 metres. Although the Stage II development of the dam took the FRL to 110.5 metres, the actual storage was subsequently improved just to a maximum of 107.5 metres.
