Non-potable Dual Pipe Water Reuse Systems and Risks to Water Quality Project

Research aims and objectives

Non-potable water reuse systems have become increasingly more popular and complex over the last three decades. These systems include the reuse of greywater (domestic wastewater excluding faecal matter and urine) and rainwater, that is either partially treated or not, for non-potable domestic use such as toilet flushing or garden irrigation via a dedicated distribution system. The aim of this research project is to review the current risks from such systems and the suitability of English and Welsh regulation to manage these risks and evolving systems. The primary focus will be on public non-potable water reuse systems operated via a separate dedicated non-potable water distribution system. Consideration will also be given to the impact of multiple individual private systems (e.g. for new housing developments or large commercial units).
