Client-developer MRPL wins project approval Environmental experts considered the design of the intake and outfall at Karnataka beach before granting approval to the desalination project which will be delivered by Wabag The market opportunity in India includes water reuse projects driven by new regulation, household-level purifi cation and desalination. Industrial clients are likely to be those procuring desalination plants in the short-term. The latest such project to receive environmental approval is Mangalore Refi nery and Petrochemicals Limited (MRPL)'s proposed facility at Karnataka. The project for the state's fi rst seawater reverse osmosis desalination plant won Coastal Regulation Zone (CRZ) clearance in February. The 300,000 m3/d plant is to be delivered by Wabag under a design and build contract worth INR 4.8 billion ($65.8 million). The scope of work comprises engineering, supply, construction and commissioning. The timeframe is 22 months. The plant will use reverse osmosis for seawater and brackish water, and ultrafi ltration. Wabag will lay 11 kilometres of piping to deliver water to the refi nery. A 10-year operations and maintenance contract will be awarded following successful commissioning. MRPL's goal is to minimise its own dependency on freshwater sources. The facility will be expandable to 700,000 m3/d in the future. The expert committee of the Union Ministry of Environment, Forest and Climate Change considered that coastal-related concerns with the project are minimal and confi ned to construction. The clearance is subject to MRPL ensuring that temporary structures installed to help with the laying of pipes are removed within a week of completion. The intake for the plant will be located 950 metres from the shoreline. The outfall, with diff users, will be 1,050 metres from shore. High-density polyethylene pipes (HDPE) will be laid two metres below the sea bed. Mechanical completion is expected in August 2020. MRPL will now seek consent from Karnataka State Pollution Board.
