About The Havant Thicket Winter Storage Reservoir (“HTWSR”) Project

This major construction project is building the first major strategic water resource in the South East for decades. It is the result of a planning collaboration between Portsmouth Water and Southern Water, through the Water Resources in the South East group, to provide more resilient water supplies. It supports reduced abstraction on chalk rivers, will deliver an overall biodiversity net gain and will provide new community leisure amenities.

Portsmouth Water intends to advertise the majority of the necessary packages of works and services for Portsmouth Water and the HTWSR project by publishing Contract Notices in accordance with the Utilities Contract Regulations 2016.
