Sistema Intermunicipal de los Servicios de Agua Potable y Alcantarillado

Sistema Intermunicipal de los Servicios de Agua Potable y Alcantarillado (SIAPA) is responsible for the production, distribution, and billing of potable water as well as the collection, treatment, and disposal of wastewater in the Guadalajara metropolitan area. The organization operates water treatment plants, pumping stations, and a network of pipelines that deliver drinking water to residential, commercial, and industrial customers. It also manages sewerage infrastructure, including collection lines and treatment facilities, to protect public health and the environment. SIAPA provides customer service functions such as meter reading, bill issuance, and payment processing through its offices and authorized payment channels. As an intermunicipal entity, it coordinates water and sanitation services across several municipalities that have agreed to jointly manage these essential utilities.

SIAPA is a decentralized public organism created under the laws of the state of Jalisco, with its governance structured around the participating municipalities that jointly own and oversee the system. Its primary mandate is to ensure reliable water supply and adequate sanitation services in accordance with national and state regulatory standards. The agency distinguishes itself by focusing exclusively on the integrated management of water resources and wastewater treatment within a densely populated urban region. In April 2025, SIAPA experienced a cyber attack that disrupted its payment processing system, prompting the agency to advise customers to use alternative payment locations while it worked with authorities to restore service. This incident highlighted the importance of cybersecurity resilience for critical water and sanitation infrastructure.
