Mexico was seen as a leader during the Paris COP21 negotiations. It has committed ambitiously to reducing 22% of its greenhouse gas emissions by 2030 compared to baseline scenario, with the potential to raise the target up to 40%, and 50% by 2050 compared to the year 2000. It is a signatory to the Paris Pact on Water and Adaptation to Climate Change. In Mexico, water utilities have a difficult task meeting user’s demands. Low tariffs, high water consumption, and a complicated legal framework have led to unsustainable water abstraction, high energy costs, high water loss, and inadequate wastewater treatment, which contribute to very high GHG emissions. Climate change will only exacerbate current conditions.
The WaCCliM project is working with the National Water Commission (CONAGUA), the State Water Commission of Guanajuato (CEAG), and the National Water Association of Mexico (ANEAS). The WaCCliM pilot utilities of San Francisco del Rincón, SAPAF and SITRATA, are already pioneering the way towards sustainable, low-carbon, urban water management. SAPAF provides water supply services, while SITRATA operates a wastewater treatment plant shared between two municipalities, San Francisco del Rincón and La Purísima. The raw water comes from groundwater wells and requires only disinfection. The drainage network does not require any pumping. The wastewater treatment plant is based on an activated sludge system.
