Session 20B: WateReuse: Making Reuse "Cool"
3:00 pm to 3:45 pm
Case Study for Datacenter Cooling Water Reuse
The Quincy Water Reuse Utility (QWRU) has just been commissioned by the City of Quincy to treat non-contact cooling water for reuse back into a portion of the Quincy datacenters. Microsoft, Washington Department of Ecology, US Bureau of Reclamation, and the Quincy-Columbia Irrigation District have played major roles in the success of this utility; the first of its kind in the State of Washington. Non-contact cooling water blowdown is treated to remove cations and anions that reduce the efficiency of evaporative cooling and helps to reduce the volume of cooling water used. In the past, potable water has been used for cooling water; however, this water is very hard and contains high levels silica. Both components negatively impact the cooling equipment; requiring additional equipment maintenance to retain the equipment’s cooling efficiency. The QWRU treats the cooling water to remove hardness and silica before being pumped back to the datacenters for cooling water. Cooling requires make-up water to replace from 60 to 80 percent water loss due to evaporation. Make-up water is provided by USBR M&I Water, potable water and, in the future, municipal Class A water. The QWRU consists of 10 distinct and specific water treatment unit processes to provide reuse water suitable for cooling. The QWRU is capable of providing from 2,304,000 to up to 3,600,000 gallons of treated water per day. Residuals from the treatment system is managed with on-site evaporation ponds and sludge management systems. The QWRU saves a precious potable water resource in an arid region of Washington State and will save up to 398,000,000 gallons of potable water in a year; enough to provide 5,450 residents potable water for a year.
3:45 pm to 4:45 pm
Strategic Planning: the key to internal alignment and program momentum
Can't seem to reach agreement? Often times, project progress is stifled by a difference of opinions. How can we create alignment among technical professionals, management, elected officials, and ratepayers?
Meaningful engagement, clear goals, consistent communications can create the synergy needed to get complex programs off the ground and the momentum required to carry them out. Even within a divided community, strategic planning can identify common threads, shared values, and a desired vision of the future.
Using regional and interstate case studies, we will discuss how strategic planning, inclusive communications, and two-way engagement create alignment, public trust, and confidence in water reuse solutions. This interactive session will provide you with the tools and tactics needed to turn barriers into breakthroughs.
