Guernsey Water completes major upgrade of Mill Street and Mansell Street water main
Guernsey Water has completed the replacement of the ageing water main beneath Mill Street and Mansell Street, the first major capital investment project of 2026, and a significant early milestone in the utility’s long‑term plan to renew Guernsey’s essential water infrastructure. The previous main, installed in 1946, had burst twice in 2025, including one incident that flooded a local business, resulting in its prioritisation for renewal.
