STATEMENT OF WORK

WFRC PROCESS WATER VAULT CLEANING

1.0 INTRODUCTION AND BACKGROUND

The Seattle WFRC requires vacuum truck cleaning of the approximately 12,156 gallon process water settling vault located under the parking lot between the wet laboratory and the facilities building. The tank is 8’ diameter corrugated steel x 32’-4” long. It has a 7’ fill level yielding approximately 11,384-gallon capacity. The vault is accessed by a manhole cover in the parking lot. It is estimated to have approximately 10 tons of wet sediment accumulation that will be removed. The vault is used to hold 2-3 ppm of chlorinated process water for a one-hour period before being dechlorinated and returned to the Magnuson Park wet land.

The United States Geological Survey (USGS) Western Fisheries Research Center (WFRC) located in Seattle, Washington. The WFRC carries out research and provide technical assistance to support the best possible stewardship of the Nation's natural resources, emphasizing fish populations and aquatic ecosystems of the West. The WFRC has a 50-year history of excellence in fisheries disciplines and are leaders in the field of molecular and microbiology within the U.S. Geological Survey (USGS). The WFRC addresses the unique issues of large western river systems such as the Columbia, and the challenges faced by desert aquatic systems and their threatened or endangered fish species.
