Solar Energy for Water Sanitation in the City of Acapulco Mexico


Amount Raised


Total Investors

Project Overview

The infrastructure required for the solar field is 138,750 solar panels of 400w each, on a plot of 94 hectares, to generate 55.5 megawatts that the local water agency needs to supply energy to all the functions it performs, from the collection, driving, distribution, wastewater treatment and office. The renovation and rehabilitation of electro-mechanical equipment is required for 15 treatment plants to properly sanitize the municipal wastewater.

  1. This project is urgent for the city, to offer the population an efficient service in wastewater sanitation, to prevent contamination of Acapulco bay, rivers and lagoons. The right to live in a pollution-free environment is a universal right, therefore to prevent contamination of the receiving bodies of treated wastewater and to compensate for the pollution that is being generated. Of 19 treatment plants in the city, 7 do not work and the rest operate at approximately 60%.
  2. To improve public finances, to generate electricity from a 94-hectare solar energy field, in order to produce all the energy needed by the local water organism, generating 55.5 megawatts and reducing the electricity payment of the municipal water organism which is 1 million dollars a month, to invest revenues from the water system in the urgent water infrastructure to avoid water scarcity in many colonies of Acapulco, being water a vital human right.
  3. Reduce the emission of greenhouse gases, generate clean energy, combat climate change to achieve the goals of the UN 2030 agenda. 4. Create local sustainable and green water agencies.

ESG Impact

The right to live in a pollution-free environment is a universal right, therefore to prevent contamination of the receiving bodies of treated wastewater and to compensate for the pollution that is being generated, everyone’s participation is required. The topography that predominates in the municipality of Acapulco plays a very important role since it presents stream channels that descend from the upper parts, dragging everything that they find in its path, added to the contributions of those who live in the margins of these streams that later from their route they flow into the sea. To solve the problem of wastewater from the different pipelines and collectors that integrates the sanitary sewer system of the municipality of Acapulco, it is necessary for the proper sanitation in the treatment plants and the deposited in receiving bodies or their corresponding reuse is applied. The rehabilitation of treatment plants should be considered a priority.


The population benefited will be all the inhabitants of the municipality of Acapulco, which according to the last official census is 810 thousand people. In addition to the more than 6 million national and international tourists who visit Acapulco every year, as they will enjoy cleaner beaches and lagoons.

SDG 17 – Partnerships to achieve the Goals

The alliance between companies, organizations, foundations, cooperation agencies and local governments, will make it possible to achieve the goals of the 2030 agenda.

Risks and Limitations

What are the key risks, constraints and dependencies related to the project?

  1. The local water agency is an autonomous paramunicipal, the plants are already built, and have the permits of the federal water and natural resources units: Semarnat and Conagua.
  2. Acapulco is in the best solar radiation zone with level 5.
  3. Mexico has cheap labor and need to generate employment.
  4. The projects presented are low risk and long term useful.

Risk mitigation and continuity

An agreement can be signed for the project with private investment for 20 years, to avoid any difference due to changes in local public administrations.
