Ecuadorian capital Quito's basic services utility Emaap-Q expects to award the recently launched consultancy tender for the design of two wastewater treatment plants in March or April of next year, company spokesperson Gissela Cola told BNamericas.
Five bidders were prequalified for the tender: US firm Hazen and Sawyer, Dutch firm Grontmij, Italian consortium Lotti & Associati-ACS-Beglar, French-Spanish consortium Ayesa-Sogreah and Spain-Ecuador's CIDO-CIC.
The consortiums have until January 18 to present their technical and economic offers, Cola said in an emailed response to questions.
The tender has a reference price of US$900,000 and an execution term of 240 days, a statement from the utility reads.
The project involves the construction of two wastewater treatment plants: El Beaterio, which will have a 0.13m3/s capacity, and La Ecuatoriana, with capacity of 0.11m3/s. Work on El Beaterio is due to start by the end of next year.
Another treatment plant is planned for northern Quito's Vindobona area and will have a capacity of 7.49m3/s. This plant will be built after the two smaller plants.
The new treatment plants are part of Emaap-Q's program designed to clean up Quito's three rivers - Machángara, Monjas and San Pedro - that will require an investment of some US$600mn, according to the program's feasibility studies.
