PJM Economics works with clients across the water sector, including policy makers, regulators, all of the UK water companies, and various other bodies, helping to apply rigorous economic thinking and robust research to the practical challenges facing them.   This include a wide range of work to support water resources management planning, drainage and wastewater management planning, price review business planning, and river basin management planning.  PJM Economics contributes to the development of best practice methodologies in many of these areas, as well as providing robust research-based estimates that feed into the plans and help shape them.
