Latest programme progress: Progress is reported on by the Delivery Assurance Group which produces quarterly reports which are published on the Scottish Government website at Water industry: Delivery Assurance Group.

Progress as shown in report for Quarter 2 2021-22, shows that delivery continued to be impacted by COVID-19, increasing timescales and costs to deliver investment. Despite these challenges, the vast majority of projects have been delivered on or ahead of target and current forecasts suggest by year end, delivery will be within the investment range set out in the Delivery Plan.

Scottish Water continues to review the impact of the COVID -19 pandemic on its investment programme.

Contribution to economic development: Scottish Water is planning £4.5 billion of critical investment to 2027 supporting over 5,000 jobs directly in the civil engineering, construction and design sectors. This is approximately 20% of the market in these sectors in Scotland.
