Redmond has been the home of the Microsoft Corporate Campus for the last 33 years and Microsoft continues to invest in our community as they build for the future. The refresh project that is currently underway replaces 12 older office buildings with approximately 3 million square feet of office space within 17 new buildings. The project is an investment for the community and the more than 47,000 employees that work on the campus. It will replace 12 older office buildings with approximately 3 million square feet of office space within 17 new buildings, boast a 2-acre open plaza, and provide the employees and the greater community a space to both gather and work.
WaterTectonics worked with the general contractor, Goodfellow Brothers – Northwest Construction JV (GBNW), to evaluate, design, and provide construction stormwater treatment options to meet demands of such a large project. The WT regulatory team currently formulates the annual Wet Weather Plans required by the local jurisdiction and is providing site permitting as well. Four chitosan enhanced sand filtration (CESF) systems are being used on site to treat turbidity & pH. These systems each treat an average of 1,000 gallons per minute, with a max flow rate of 1,200 gallons per minute. WaterTectonics, as approved by the Washington Department of Ecology, provided Certified CESF Operator Training so that the GBNW staff can operate the system reducing operational costs.
