Performance Work Statement

Nogales International Wastewater Treatment Plant

1.1 Project Overview

The United States Section of the International Boundary and Water Commission (USIBWC) has a requirement to complete the replacement of the Train 1 Bioreactor Diffusers, two Blowers and

4 RAS Pumps in the Nogales International Wastewater Treatment Plant (NIWTP). Replacing the Train 1 Diffusers, two Blowers and 4 RAS Pumps is required to maintain safe and reliable operations of NIWTP.

NIWTP Process

The NIWTP is a Modified Lutzack Enttiger (MLE) Biological Nutrient Removal (BNR) type facility. The NIWTP treatment Capacity is 14.74 MGD and has been operating at or above capacity since constructed in 2009.

The facility consists of a headworks, three Bioreactor basins commonly served by five 400 hp

Spencer centrifugal blowers with each basin separated into seven zones , three circular clarifiers, four return activated sludge (RAS) pumps, two 2.5 meter belt filter presses, one aerobic digester, one waste storage lagoon, five traveling bridge filters and a Ultraviolet distinction facility.

1.2 General

This is a non-personnel services Contract to perform the replacement of Train 1 Diffusers, two

Blowers and 4 RAS Pumps. The Government shall not exercise any supervision or control over the Contract service providers performing the services herein. Such Contract service providers shall be accountable solely to the Contractor who, in turn is responsible to the Government.

1.3 Description of Services

The Contractor shall provide all personnel, equipment, supplies, transportation, tools, materials, permits, and supervision necessary to perform the work as defined in this Performance Work
