The Ghana Water Company Limited (GWCL) has attributed persistent water losses and leakages partly to ageing pipelines, with some infrastructure dating back to the 1960s.
GWCL Managing Director and Chief Executive Officer Adam Mutawakilu said the deteriorating condition of old pipelines has weakened their structural integrity, making them more vulnerable to ruptures, particularly when water pressure increases.
He cited pipelines in the Weija area as an example, noting that some have been in operation since the 1960s. He also highlighted challenges with ageing metallic pipelines in parts of Accra.
Mr Mutawakilu said the GWCL began prioritising the replacement of damaged and obsolete pipelines from March 2026, shifting greater attention from network expansion to rehabilitating existing infrastructure.
The replacement programme has contributed to a gradual reduction in non-revenue water, the portion of water produced that does not generate revenue. Non-revenue water fell from 52.2% in December 2024 to 51.6% in December 2025, before declining further to 47.6% by June 2026.
The GWCL plans to continue replacing weakened pipelines to reduce leakages, minimise water losses and improve the reliability of water supply.
