The nation’s rate regulating agency says that two proposed nearby sewage plants should be combined.
The water section of the agency, the Autoridad Reguladora de Servicios Públicos, directed its comments to the Instituto Nacional de Acueductos y Alcantarillados and the Empresa de Servicios Públicos de Heredia.
The institute, known as AyA is building a plant in La Carpo adjacent to the Heredia province border.
The Autoridad said that only about 4 percent of the nation’s sewage is treated. Some is directed to septic tanks. But the majority of Central Valley sewage flows into streams that eventually end up in the Río Grande de Tárcoles and then the Gulf of Nicoya.
The Autoridad noted that the two utility firms have been in discussions about combining efforts, and it gave AyA 60 days to present a joint proposal.
The Heredia plant is much smaller than the AyA project, so the Autoridad said that it might better be considered an enlargement of the La Carpio plant.
The agency noted that there would be more efficiency and reduced costs if the two utilities work together.
