Projects

Port of Seattle, SeaTac International Airport Clear Water provides construction site stormwater treatment for the third runway embankment project. This project comprises 376 acres of disturbed area where a new commercial aircraft runway is being constructed. Water treatment on the site was previously handled by others and in September of 2005, the Port of Seattle opened the work up to competitive bid. In October of 2005 Clear Water was awarded the project because of their engineering expertise, efficient equipment design, operational approach and cost savings implementation of a remote telemetry data management system. Over 35 million gallons of stormwater have been treated and discharged without a single water quality violation since Clear Water began site operations. Clear Water will incorporate an additional 96 acre drainage basin for stormwater treatment in the winter of 2005- 2006.

Mine Project Clear Water Compliance Services, Inc. (Clear Water) provided a portable flocculation and filter-press system at a mine bioreactor. Snowmelt, rain, and groundwater interact with the waste rock from a century of mining operations, creating sulfuric acid, which in turn leaches additional contaminates from the native materials such as arsenic, copper, nickel, zinc, chromium, aluminum, and iron. The resulting acid rock drainage (ARD) eventually affects water quality of a river system. The bioreactor protects surface water with a process that reduces the dissolved metal concentrations in the water and raises the pH of the water and sludge. The need to periodically remove sludge from the system is a critical factor in maintaining desired capacity and retention time in the bioreactor. Clear Water processed 350,000 gallons of sludge material to stackable “cake”. The system produced 3 tons of cake every 6 hour shift and was able to reduce disposal cost by over 50% compared to hauling the material using tanker trucks. This process allowed the waste to be re-classified, therefore creating significant savings in time and disposal expense.

Highway 18, Maple Valley, WA This is a major highway road expansion project. Stormwater from this site is received by Taylor Creek and the Cedar River, both protected waters because of listed salmonids. Prior to Clear Water’s presence on this project, January 2005, there were some mishaps that caused great environmental concern about the project. Clear Water’s remediation proposal was implemented under great scrutiny from Ecology, WSDOT, King County, an environmental firm and two major contractors. The site was heavily monitored and samples were routinely taken from various entities to test the system performance. Within three weeks of the treatment systems being operational, a 100-year storm event put the treatment system and operations into overdrive. Turbidity values were witnessed in excess of 6000 NTU. To date (May 06), this site system has discharged 46,635,132 gallons of water without a single discharge being above water quality limits. This site operates on a 24 hour basis with even the slightest amount of precipitation due to the vulnerability of the receiving waters.

Costco, Woodinville, WA This project was the construction of the Woodinville, Costco Wholesale store. Water from this site discharged into the highly sensitive and much publicized Little Bear Creek. The creek is classified as class AA waters and is protected under the ESA. The site also had significant challenges in the substrate because the site was previously an auto wrecking yard. Operations went from November 18, 2004 through August 16, 2005. A total of 10,351,775 gallons were treated and released under water quality limits. The project had 3rd party analysis data collection and monitoring. Clear Water's performance on-site allowed the contractor to complete the project without a single water quality violation.

Olhava Project, Poulsbo, WA Initial operations commenced March 2, 2005 and ended January 22, 2006. The Olhava site was designated for mixed use of large retail stores, residential housing and other industry. This project received national attention due to the highly sensitive receiving water and public interest. Initial treatability of this site was difficult due to high organic material interference (OMI) from tanins and lignens. That issue was rectified and 14,260,275 gallons of treated stormwater was released with no violations of water quality standards. The discharged released from this site formed the headwaters of Johnson Creek which discharges into Liberty Bay. Clear Water has been retained for an additional phase of this project and is in current operations on-site. To date (May 2006) Clear Water has treated an additional 12 million gallons in operating the second phase of this project.
