Reduce Cooling Water Use Immediately


MENLO PARK, Calif., Oct. 9, 2015 /PRNewswire/ -- Boardrooms are full of discussions around corporate responsibility and sustainability.  The news is filled with more communities suffering drought conditions and energy usage spikes.  There is no time to waste in addressing these issues which are critical to our communities.

Technology is able today to reduce the amount of water used by most data centers (who use evaporative cooling) by 10%–50% or more. Ex.:

The reason maximally efficient operation is not the norm is not the cost of the solution; it is tradition, lack of incentives and disincentive.

Tradition: Water and wastewater costs have been a small part of the total cost of ownership of a data center, therefore tradition dictates a low priority to conserve water and minimize wastewater. 

Lack of incentives: ROI rules the roost. In locations where incentives provided by water agencies are not available, marginal projects are not considered until the issue becomes one of compliance. Incentives are needed in some cases to tip the scale.  

Disincentives: Water treatment suppliers sell chemicals that are directly tied to the amount of water used. When water usage decreases due to efficiency gains, less chemistry is used and a direct hit to the water treatment supplier's bottom line results. 

Today we have the ability to instantly and continually monitor and address an unlimited number of things including the following that just happen to impact water efficiency:

  1. The water chemistry in the cooling tower
  2. The amount and cost of the water and chemical used
  3. How the cooling tower is operating vs. design and current atmospheric condition.
  4. How weather is impacting the need for and quantity of evaporative cooling on line.
  5. The full process capability and analytics needed to optimize water and energy consumption.

The questions we need to ask regarding all of the above are:

  1. Is it optimal?
  2. If not why not and what is the fix?
  3. When can we deploy resources to remedy the suboptimal condition?

In 800 data centers in CA the savings potential is staggering:

This is

  1. the carbon equal to taking over 11,000 cars off the road.
  2. the power used by 93,000 homes in CA for a year.
  3. enough water to provide for the needs of 231,312 average Californians.

The savings of our most precious resources can be delivered today.
