Water Supply Well Replacement

D-B Replacement of Base Water Supply Well C
Eielson Air Force Base, Alaska

The former base water supply well C was deactivated and disconnected from the Eielson AFB water supply due to the presence of TCE contamination and groundwater restriction goals. With the reduced water capacity, Eielson AFB was in a position where the water plant could not guarantee production of the volume or pressure required to meet fire suppression requirements.

Ahtna’s services included contract management, submission of accurate, on-time, quality contract deliverables and timely identification and solution of impediments to successful project execution. Technical requirements included Ahtna’s early involvement in the process to allow development of the most cost-effective and technically sound approach. The Air Force Center for Engineering and the Environment (AFCEE) relied on Ahtna’s expertise in recognizing and addressing problematic issues and successful execution of this contract. The scope of work included: The scope of work included:

During the proposal phase, Ahtna was instrumental in recommending a drilling and exploratory well 6” – 300’ deep to determine aquifer strata and optimal screening design. Ahtna also recommended the installation of a dual-drive well pump, which utilizes an electric motor and a diesel engine. This configuration was more economical to build, as well as operate, requiring much less engine horsepower and electrical equipment that resulted in over $123,000 in savings to the client.
