Jalisco governor details US $1.3B investment in Guadalajara’s water infrastructure: Wednesday’s mañanera recapped

Mexico’s federal government and Jalisco agreed to invest 25 billion pesos in water infrastructure for the Guadalajara metropolitan area. The plan matters because thousands of residents recently protested for clean tap water, and much of Guadalajara’s supply travels through an exposed canal vulnerable to contamination.

The centerpiece is two aqueducts. One would carry water 42 kilometers from Lake Chapala to Guadalajara. The other would run 31 kilometers from the Calderón Reservoir to the San Gaspar treatment plant. Additional projects would support the new pipelines and help prevent contamination along the route.

The federal government would provide 14.5 billion pesos, while Jalisco would contribute 10.2 billion pesos. Officials said financing would come through budget adjustments. Construction could begin next year, and the aqueducts are expected to be completed by the end of 2028. Officials also promised no new debt, privatization or water-rate increases.

An aqueduct is a constructed channel, pipeline or similar system that moves water from a source to another location. In this project, the aqueducts would provide enclosed routes toward Guadalajara and its treatment infrastructure. That matters because an enclosed, managed route can reduce exposure during transport.

One planned aqueduct would run 42 kilometers from Lake Chapala to Guadalajara. The second would travel 31 kilometers from the Calderón Reservoir to the San Gaspar water treatment plant. The article also mentions a new network of collectors to help stop water from Chapala becoming contaminated in the Las Pintas reservoir.

The aqueducts are not the entire plan. They are part of a wider 25-billion-peso package of complementary projects. Work could start next year, and officials expect completion by the end of 2028. The stated goal is to move water with less contamination, leakage and evaporation before it reaches residents.

The Guadalajara water project carries a total announced investment of 25 billion pesos, equivalent to US$1.33 billion in the article. Its two main aqueducts would cover 73 kilometers combined: 42 kilometers from Lake Chapala to Guadalajara and 31 kilometers from the Calderón Reservoir to the San Gaspar treatment plant.

The federal government would contribute 14.5 billion pesos. Jalisco would provide 10.2 billion pesos. The governor said the total includes several projects that complement the aqueducts, so the two pipeline distances do not represent every part of the investment. The figures show a joint effort rather than a single construction contract.

Officials said the money would be made available through budget adjustments. They ruled out new debt, privatization and higher water rates for the metropolitan area. Work could start next year, while the aqueducts are expected to be finished by the end of 2028. The plan therefore combines large public spending with a phased construction timeline.

The aqueducts are designed to address problems that occur before water reaches Guadalajara. The governor said a significant share of Lake Chapala water currently travels through an open canal built 70 years ago. Because the canal is exposed to wastewater discharges, water can become contaminated during its journey.

A new aqueduct would create a more controlled route from Lake Chapala. Lemus said it would allow the city to use 100% of that water without contamination along the journey and reduce waste from leaks or evaporation. The project also includes a new collector network to prevent Chapala water from becoming contaminated in the Las Pintas reservoir.

The plan could improve the reliability and quality of water reaching treatment and distribution systems. However, the article describes construction as something that could begin next year, not as completed work. The aqueducts are expected to be finished by the end of 2028, so the existing canal remains important in the meantime.

Lake Chapala is central to Guadalajara’s water supply because the governor said it provides 60% of the metropolitan area’s water. That makes the lake more than one source among many: it is the main source identified in the announcement. Protecting its water during transport is therefore a major reason for the new infrastructure.

The current route creates risk because a significant share of Chapala water travels through an open canal built 70 years ago. Lemus said the canal is exposed to wastewater discharges. The state also detected 150 irregular discharges in the canal and said they were being closed, with responsible parties facing sanctions.

Heavy dependence on one source means contamination, damage or reduced availability could affect a large share of the city’s supply. The planned aqueduct from Chapala would provide a more protected route. Officials also said the broader project could help supply quality water to metropolitan residents, with completion expected by the end of 2028.

The federal government and Jalisco are sharing the project because the planned infrastructure serves Guadalajara’s metropolitan area while involving both levels of government. Their agreement covers the aqueducts and other supporting works needed to improve water quality and supply. The announcement followed large protests demanding clean tap water.

The total plan is 25 billion pesos. The federal government would contribute 14.5 billion pesos, and Jalisco would provide 10.2 billion pesos. The money would support the 42-kilometer Lake Chapala aqueduct, the 31-kilometer Calderón-San Gaspar aqueduct and complementary projects such as collector networks.

Lemus said the governments would make the money available through budget adjustments. That means officials presented the work as a reallocation within public budgets rather than borrowing. They also stated that there would be no new debt, privatization or increases in water rates for Guadalajara’s metropolitan area. Work could start next year.

Water from a lake or reservoir is not automatically safe to drink. A treatment plant typically removes suspended material, reduces harmful microorganisms and adjusts water quality before distribution. The exact process varies by facility. The article identifies the San Gaspar treatment plant but does not provide its technical steps.

In general, raw water first passes through screens and settling or filtering stages. Treatment chemicals may help particles clump together, while disinfection reduces disease-causing organisms. The treated water is then tested before entering pipes. Protected pipelines, such as the planned aqueducts, help prevent new contamination during transport.

For Guadalajara, the planned route would connect Calderón Reservoir with San Gaspar and Lake Chapala with Guadalajara. The project is intended to reduce contamination, leaks and evaporation during movement. It does not replace treatment or household safeguards. Construction could start next year, with the aqueducts expected to be completed by the end of 2028.
