Technical requirements: EIB - Guayaquil’s municipal project to provide universal wastewater management services (EC-Guayaquil)

The contract involves the construction of a new wastewater pumping station at the Pradera site located at the southeast of the City of Guayaquil. Currently, a pumping station exists at the same site.

Therefore, a new pumping station is needed, next to the existing one, with the capacity to manage the project’s wastewater flow to be discharged in the WWTP Las Esclusas.
The land available has 3 acres, with enough space available for the new pumping station and the necessary facilities to provide with electric and operating controls and additional services. The existing pumping station must be fully operational until the new pumping station is finished, operational and ready to replace the existing one. The existing pumping station will then be demolished.

The pumping station will have a capacity of 6,435 lps @23.94 m CDT with 7 pumps, 6 in operation and 1 in reserve, leaving space for an additional one which will be installed in the future. The collected wastewater will be pumped to the WWTP Las Esclusas trough a pipeline with inside diameter of 1927 mm.
