Flushing Program Plan Development - Statement of Work (16 July 2025) Eielson AFB, Alaska

2 of 7 Controlled Unclassified Information (CUI)

1.0 INTRODUCTION

Water distribution systems require regular flushing to maintain water quality and system efficiency by removing accumulated deposits from pipe walls. Two primary methods used are conventional flushing and unidirectional flushing. Conventional flushing involves opening hydrants to allow water to flow freely, but it requires significant water usage and is less effective at clearing deposits.

Unidirectional flushing, a more targeted approach, forces water through selected pipes at higher velocity by closing specific valves, thus improving cleaning efficiency while using less water. It also helps identify faulty valves and hydrants and enhances overall system reliability.

This Statement of Work (SOW) defines the requirements for the development and implementation of a Unidirectional Flushing Program (UDFP) at Eielson Air Force Base (AFB), AK. The purpose of this effort is to ensure accurate GIS representation, optimize water system performance, and establish a systematic approach for flushing procedures.

2.0 DESCRIPTION OF SERVICES

The Contractor shall review existing documents, assess hydraulic conditions, configure a GIS-based hydraulics model, develop a flushing sequence, and conduct condition assessments. The Contractor shall ensure compatibility with Eielson AFB’s GIS feature layers and standards.

3.0 SCOPE OF WORK

The scope of work encompasses data review/entry, hydraulics modeling, and UDFP development.

The period of performance for this work is six months after Notice to Proceed.
