CMDP, a Joint Venture between Costain and MWHT, have been selected by Southern Water to deliver essential infrastructure solutions for its next AMP8 investment programme. The award is for an initial seven-year term worth at least £500m to Costain, with an option to extend by up to five years.

The strategic delivery partner framework will deliver upgrades to water and wastewater assets, including treatment sites, pumping stations and reservoirs, during Asset Management Period 8 (AMP8) and beyond. Southern Water expects that its AMP8 programme, which runs from 2025 to 2030, will be the largest it has ever undertaken.
