Mexico's Jalisco water utility Siapa has said it needs some 8bn pesos (US$679mn) to optimize the state's potable water pipeline network and bring down water losses, local daily El Informador reported.
While the state's pipeline network has an estimated 25-year lifespan, many pipes have not been replaced since the 1930s.
The problems are mainly concentrated in the growing metropolitan areas. In state capital Guadalajara, up to 70% of pipelines are obsolete, the report said.
Jalisco's water loss rate is somewhere between 15% and 20%, according to Siapa. However, in some areas losses are reported to reach up to 40%.
