In preparation for the upcoming AMP8 2025-30 water spending period, Southern Water has awarded contracts to three companies across four new contracts to boost its wastewater network performance.

Work will be carried out across four lots. Maintenance and manholes workstreams will be the responsibility of Lanes Group, while Cappagh Browne will deliver on sewer rehabilitation projects, and McAllister Bros on sewer sealing.
The partners will be responsible for delivering essential frontline sewer services. From responding to emergency calls, to rehabilitating existing sewers, these providers will work collaboratively with Southern Water to further improve our environmental performance and customer service.
The contracts will start in April 2025, spanning all five years of the AMP8 spending period, with the potential for extensions. The total value of the combined contracts is approximately £540 million.
The announcement follows Southern Water’s previous award of contracts under the Capital Delivery supply chain for AMP8.
Southern Water’s Head of Wastewater Networks, Alex Saunders, said:
“We are delighted to have secured partnerships with industry leading suppliers who are experts in their respective technical disciplines. These agreements prepare Southern Water to meet the service levels expected by our customers and will help us to deliver on our environmental improvement ambitions for years to come.”
