IDE Technologies delivers a tertiary treatment reverse osmosis plant to Chennai Metropolitan Water Supply & Sewerage Board (CMWSSB)

IDE Technologies has completed the erection phase of the Tertiary Treatment Reverse Osmosis plant for Chennai Metropolitan Water Supply & Sewerage Board (CMWSSB) at the facility’s location in Koyambedu, City of Chennai, State of Tamil Nadu.

The Chennai area has very challenging water circumstances due to severe and prolonged drought conditions. CMWSSB needed a suitable partner to Design, Build & Operate (DBO) a 45 MLD Tertiary Treatment Reverse Osmosis (TTRO) plant in Koyambedu, including supplying and laying of a transmission pipe for conveying product water to various industries situated in Irungattukottai, Sriperumbudur and Oragadam.

The DBO project also included a 15-year Operation and Maintenance period, and was funded by the Jawaharlal Nehru National Urban Renewal Mission (JNNURM), the Government of India (GOI) and the Tamil Nadu Investment Promotion Program (TNIPP), demonstrating the local authorities’ commitment in improving the difficult water conditions in the area.

With a capacity of 45 MLD, the TTRO plant was constructed in 2018 in partnership with VA Tech WABAG Ltd., in order to produce non-potable recycled water for industrial use. This industrial-grade water supply helps relieve some of the extensive water demand generated by the industrial activity in the area, and allows a larger portion of the local potable water sources to be allocated for municipal use.

The IDE-WABAG consortium has been selected by the client because of their ample experience in RO and Industrial Reuse technologies, flexible financing capabilities and strong local presence. As part of the consortium, the technologies incorporated in this project included Gravity Sand Filters, Ultra Filtration (UF) and Reuse Reverse Osmosis treatment, in order to treat the very poor quality of the Wastewater Treatment Plant effluent.
