The construction of a 23.8 kilometres main transmission pipeline for sourcing drinking water from the Neyyar dam site to the capital city is expected to start soon.
The Kerala Water Authority (KWA) has awarded the work to Erode-based Annai Infra Developers.
The work involves the supply, laying, testing, and commissioning of a 1422-mm, mild steel, clear water gravity main from the 120-mld water treatment plant proposed at the site to the ground-level storage reservoir of the KWA at PTP Nagar.
Survey for the construction of the transmission main has been completed and the work does not involve land acquisition. The pipeline construction is expected to be completed in 18 months.
The Neyyar project envisages a daily supply of 100 million litres to the city and 20 million litres a day (mld) to Vilappil, Vilavoorkal, Maranalloor and Malayinkeezhu panchayats.
The Neyyar reservoir was designated as a possible alternative water source for the city region after the KWA was forced to rig temporary pumping facilities there when water levels in the Peppara dam—the main source—dipped alarmingly during the 2017 summer.
