We have handled your request as a request for environmental information under the Environmental Information (Scotland) Regulations 2004 (EISRs) and consider it to be exempt from disclosure under the EISRs because we do not hold it. We have provided more information on the EISRs, how they apply and why we have applied the exception in the Annex to this response.

Answer |
| Annual replacement rates for water and sewer pipelines as percentage of total pipeline length, and any relevant targets for replacement rates, for the period 2020–2024 (five years) | Please refer to our annual return & regulatory accounts data, specifically tables D5 and D6 which provide data on mains renewed and sewers replaced (as well as total lengths). |
| Water leakage as percentage of distribution input, for the period 2020–2024 (five years) | Please refer to our annual return & regulatory accounts data, specifically tables A2 which provides data on leakage and distribution input. |
| Please note that while we do not set targets for replacement rates, we do include an annual run-rate for replacement of different asset types which you can find in tables G2. This is not a target that Scottish Water is required to meet. | |
