A key part of this strategy involves sealing sewers to limit water infiltration and inflow, helping to protect the environment and improve network resilience. We are inviting suppliers with the capability to provide sewer sealing repairs to submit a response to this Conditions of Participation (COP). The COP is divided into two Lots: Lot 1: Full Length Lining & Ground Water Infiltration Sealing Lot 2: Novel Ground Water Infiltration Sealing
Lot Information

Planning Information
Southern Water is initiating a market engagement exercise to help shape our future procurement strategy for Sewer Sealing services. This will begin with the release of a Request for Information (RFI). We encourage all interested suppliers to participate. Please note that Southern Water reserves the right to engage in further discussions with any organisation, regardless of whether they respond to the initial RFI. Depending on the insights gathered, we may follow up with: One-to-one meetings (either in person or online), A live Marketplace event or townhall session (either in person or online), and/or a second RFI, if deemed necessary. The initial RFI is scheduled to be issued on 17th October 2025.
