City in Sonora, Mexico, gets $5.7 million wastewater grant
A Sonora, Mexico, city has received a $5.7 million grant from the North American Development Bank for projects covering its wastewater collection and treatment program.
March 7, 2001—The water utility, Organismo Operador Municipal de Alcantarillado y Saneamiento de San Luis R�Colorado (OOMAPAS), has received a $5.7 million grant from the North American Development Bank (NADB) through its Border Environment Infrastructure Fund (BEIF), which is funded by contributions from the U.S. Environmental Protection Agency (EPA), to apply towards the cost of the projects included in the Wastewater Collection and Treatment Program for the city of San Luis R�Colorado, Sonora, Mexico.
San Luis Rio Colorado is located in the northwestern region of the state of Sonora, and borders Arizona to the north, the Cort�Sea to the south, the municipalities of Puerto Pe�asco and Plutarco El� Calles to the east, and the State of Baja California and the Colorado River to the west. It has an estimated population of 170,000. Ninety-six percent of the population receives water service and 40 percent receives sewage service; however, the untreated wastewater is discharged into the Colorado River.
The project consists of the construction of an interceptor for a sanitary sewer system (6,000 m), two pump stations and a wastewater treatment plant. OOMAPAS intends to contract construction management and supervision services for the construction of these projects for the purpose of monitoring project performance and the use of funds provided by the NADB.
The consultant will be expected to provide follow-up on technical and administrative aspects of project progress, prepare reports and project-related documents, participate in meetings with OOMAPAS and the construction contractors, as well as supervise the work of the contractors. The estimated budget for this work is approximately $380,000, including 10 percent for contingencies. The services are scheduled to begin in May 2001, with an expected duration of 12 months.
OOMAPAS issued a general invitation to submit expressions of interest in participating in the selection process, which will be carried out under the terms of the NADB.
