Portsmouth Water published their draft 2009 Water Resources Management Plan and the accompanying Strategic Environmental Assessment.

The proposed development of a winter storage reservoir at Havant Thicket will deliver the long term legacy of a substantial water resource, and an enhanced and vibrant environment with substantial opportunities for recreation and learning.

• Portsmouth Water plans to promote and construct a winter storage reservoir for public water supply purposes on Company-owned land at Havant Thicket, Rowlands Castle, Hampshire.
• The reservoir is expected to hold around 8.7 million cubic metres of raw water pumped from the Company's existing sources at Havant & Bedhampton Springs.
• It would be approximately one mile long and half a mile wide.
• Water from the reservoir would be treated at the existing Farlington Water Treatment Works on Portsdown Hill, Cosham, although it may be necessary to add some pre-treatment processes at Farlington or on an alternative site.
• Demand forecasts carried out by the Company for OFWAT's 2004 periodic review of water charges indicate that the reservoir will be required in service by 2020/21. However, before construction can commence, there are a wide range of issues to be addressed.
• The total estimated cost of the scheme is in excess of £30m.
• A scheme of this magnitude and impact will require careful management of all the issues involved if the project is to proceed successfully. The Company therefore established a Stakeholder Group in 2004 which it chairs to provide a forum where interested parties can contribute to and be informed of the development and details of the scheme.
