Rehabilitation of the Wastewater System in the Downtown Area of Sabinas, Coahuila.

Status: Completed Construction

Background

According to SIMAS, the wastewater collection system in Sabinas covers approximately 75% of the community, serving an estimated 15,971 residential connections. Currently, the wastewater collected in Sabinas is discharged into the Blanco or Aguililla Creeks under a concession authorized for a fixed term, which will end in 2017. To address the lack of wastewater treatment for the community, the State of Coahuila, through the Coahuila State Water and Wastewater Commission (CEAS), is currently constructing a wastewater treatment plant (WWTP) that will have sufficient capacity to treat all wastewater flows collected
by the sewer system.

In addition to the need for adequate wastewater treatment facilities, the wastewater collection system in the downtown area of the community was built in 1954 and has exceed its useful life. Several sections of sewer pipeline have completely deteriorated or are badly worn. Consequently,collapsing lines and sewage spills are a frequent occurrence. The utility’s
operation and maintenance costs have also increased to cover the corresponding repairs.

Description

The Project consists of the rehabilitation of the wastewater system in the
downtown area of Sabinas, which includes the following components:

  • Replacement of 9,409 ft. of 8-inch PVC pipeline;
  • Replacement of 4,390 ft. of 10-inch and 12 inch PVC pipeline; and replacement of 462 sewer connections.

Benefits

The proposed Project will provide adequate wastewater collection
infrastructure to prevent raw wastewater spills and support the efficient and safe operation of the wastewater collection system in the city’s downtown area.

In particular, the proposed improvements to the wastewater system will ensure reliable service for 462 residential wastewater connections.
