In San Francisco del Rincón, two utility companies, SITRATA (Servicio de Tratamiento
y Deposición de Aguas Residuales) and SAPAF (Sistema de Agua Potable y
Alcantarillado de San Francisco), are collaborating on projects to improve their
services and lower their greenhouse gas (GHG) emissions. SITRATA manages
wastewater, while SAPAF is responsible for drinking water and sewage. With
guidance from the WaCCliM project, both utilities have undertaken a strategizing and
implementation process similar to that proposed in the “WaCCliM Roadmap to a Low-
Carbon Urban Water Utility”.
As a result, SAPAF have increased wastewater treatment coverage from 48% to 81%
and improved the energy efficiency of their pumping stations. The magnitude of the
increase in treatment coverage was by far the biggest achievement in GHG reduction.
