Water demand in the Valley of Mexico and in North Baja California largely outweighs both immediate and longer-term supply. The main aquifer in the Mexico City region, supplying up to 70% of the residential needs, is being drained beyond the rate of replenishment, with a current stress level of 132% . Climate change and poor water management are exacerbating these circumstances and, as a consequence, the City’s authorities have been increasingly forced to resort to the implementation of water-rationing measures over the past few years , . Similar problems are found in the city of Tijuana, where the water stress is classified by CONAGUA as ‘high’, with a rate of utilization of renewable water resources of 73%. Moreover, in Tijuana water availability issues are further exacerbated by water quality and trans-boundary water pollution problems. Apart from the environmental problems caused by the residential sector’s growing water footprint, hot water is also one of the main factors impacting residential energy bills, due to the use of fossil fuels (natural gas or liquefied petroleum gas) and electricity for water heating. Finally, the use of hot water is also one of the main sources of emission of greenhouse gas (GHG) and other pollutants (such as nitrogen oxides (NOx) and sulfur oxides (SOx)) in the residential sector. The use of showers and faucets represents the single largest use of water in Mexican households, averaging a daily consumption of up to 250 liters per person . However, water fixtures in the residential sector are typically inefficient, using about 40% more water (i.e. approximately 25% more energy) than modern water-saving devices available on the market. The water scarcity problem outlined above has a number of causes, the most important of which being the spike in demand caused by rapid urbanization towards metropolitan areas, especially evident in the Valley of Mexico. Available local water resources are limited throughout the country, and particularly evident within Mexico City, which lies 2200m (7200+ ft) above sea level making groundwater pumping energy-intense and therefore expensive. In addition, water is typically conceived of as an unlimited public good, which limits price increases and payment enforcement. Household rates are heavily subsidized and equal to approximately 15% of the supply costs. The percentage of water paid for by end users is 24% in Mexico City, and 36% in the metropolitan area. The impact of the use of hot water on energy bills is poorly understood, and there is generally poor public awareness on the significant water, energy, and GHG savings potentially available through the installation of efficient residential water fittings. In addition, the upfront cost of the installation of the more efficient water fixtures usually represents an additional barrier to the deployment of the technology.


Achieve economic saving for low-income beneficiaries through reduced water and fuel usage.


Demonstrate the viability of the business model used (distribution of water and energy saving devices with financing from carbon credits) and foster large-scale adoption of the model.


  • Awareness campaign and participation : Will include the identification of the specific neighborhoods and households to be included in the project, defining the project boundaries. It will also include a campaign to inform residents of the prospective program implementation (through stakeholders consultation meetings organized in each target residential area), and the preparation of informative material to be distributed during the installation phase.
  • Design, manufacturing, deployment more efficient water fixtures: This component will include the manufacturing of the mold necessary for the production of the faucet fixtures, which will be exclusively used for the production of the pieces to be used in this project (and the eventual 2nd scale-up).
  • ‘Mujeres Plomeras’ Program: This component will identify and provide training to the technical personnel that will be in charge of the removal of the existing water fixtures and the installation of the new more efficient ones.
  • Administration and Knowledge management: This component will include the consulting services for the development and registration of the project under the rules of the Gold Standard carbon certification scheme, as well as the relative accounting and legal preparatory work. Moreover, this component will include the creation and maintenance of a database and web-based reporting tool for project management. Finally, this component will include knowledge sharing and the development of knowledge transfer product(s).

Aún cuando parezca que el ejecutor tiene todos los elementos bajo control, se recomienda dar plazos un poco más holgados para la ejecución de las actividades y de esta forma evitar caer en incumplimientos y consecuentemente en proceso de cancelación.
