Southern Water has published a Periodic Information Notice seeking expressions of interest from suppliers for its AMP 8 Capital Programme Delivery worth an estimated £7.5 billion.

Southern Water said it is anticipating that AMP8 will be the largest investment programme it has ever undertaken, given its plans for the Water Industry National Environment Management Programme (WINEP) and its own Water Resources Management Plan (WRMP).
The water company is looking to put a collaborative framework in place with a small number of Strategic Delivery Partners to cover its base maintenance programme and the following 6 main areas of its PR24 business plan for the 2025-2030 investment period.
Wastewater
- Nutrients programme
- Combined Sewer works
- Bio Resources
Water
- Water recycling
- Upgrades at its 4 strategic water production sites
- Network resilience
Southern Water said the lotting structure will be finalised following further market engagement and is now inviting parties interested in providing any of the water or wastewater capital spend areas outlined to respond to this PIN, The utility will shortly be engaging with all interested parties to seek the market’s inputs to assist in developing the appropriate lotting structure.
Southern Water is looking to appoint at least two, but up to four, Strategic Delivery Partners working across the Asset Lifecycle Process.
The partners will help the water company to develop and choose solutions for complex elements of its portfolio and then deliver the design and construction work to achieve the outcomes required.
Southern Water anticipates allocating projects, programmes or tranches of work from those on the Framework shortly after it receives the Final Determination from Ofwat for its AMP8 Business Plan which is in development.
The Strategic Delivery Partners within this framework will be required to bring a coverage of specialist skills and capacity to deal with nature-based solutions, partnership working, net zero and catchment-based solutions.
