Puerto Viejo Wastewater Sewerage

and Treatment System

(Completed)

ABOUT THE PROJECT

The construction of the Puerto Viejo wastewater sewerage and treatment system, located in the province of Limón, is part of the agreement signed with AyA to strengthen water and sanitation infrastructure in different regions of the country. The project includes three main components: a wastewater collection network with a pumping station, a wastewater treatment plant with tertiary disinfection treatment, and a discharge pipeline for treated water into the sea.

The initiative aims to improve environmental and public health conditions in the community through the safe treatment of wastewater, preventing groundwater contamination and reducing risks to both human health and marine ecosystems. In addition, the system has been designed to enable a future connection for the reuse of treated water in irrigation projects, sanitary services, and other sustainable uses.

The project will benefit approximately 3,000 people and contribute to strengthening the sustainability and resilience of Puerto Viejo’s sanitation infrastructure.

UNOPS' ROLE

UNOPS acts as the implementing agency responsible for the procurement, auditing, and approval of complementary studies, including the Environmental Impact Assessment, as well as the development of construction designs for the Puerto Viejo sewerage system. UNOPS is also responsible for procuring the construction works for the treatment system.

In addition, UNOPS promotes the project’s social management processes and strengthens the capacities of the AyA-CABEI Executing Unit, incorporating components related to climate resilience of hydraulic infrastructure, environmental management of the works, and social communication.
