WW, WWi host Twitter Chat with Grundfos about water-energy nexus

On Thursday, March 12, WaterWorld and Water & Wastewater International hosted their first Twitter Chat with Grundfos, which discussed the impact and importance of the water-energy nexus in the industry today, particularly with regard to pumping technologies.

March 18, 2015 -- On Thursday, March 12, WaterWorld (WW) and Water & Wastewater International (WWi) hosted their first Twitter Chat with Grundfos, a global specialist in the water pumping, handling and circulation industries, which discussed the impact and importance of the water-energy nexus in the industry today, particularly with regard to pumping technologies.

Water and energy are inextricably linked. Water is required to produce energy, while the pumping of water is estimated to consume 10 percent of the world's electricity. Simply put, water requires energy, and energy requires water. This relationship is referred to as the water-energy nexus.

#WaterChat provided participants the opportunity to communicate and interact with an online gathering of water industry colleagues, as well as a number of subject matter experts from Grundfos and both WW teams. Moreover, the event served as a valuable tool for individuals to gain valuable insight into the water-energy nexus, discuss a variety of optimal solutions and ultimately raise awareness of the subject.

The hour-long public forum included a live Q&A session and featured Art Haddaway, WW assistant editor (@WaterWorldMagazine); Tom Freyberg, WWi chief editor (@TomFWaterBoy); and Morten Riis, Grundfos business development manager (@mxriis, @Grundfos);among several other key market players who contributed to the discussion.

During the chat, the WW teams proposed five important questions that led to a wide range of intriguing and insightful responses through more than 260 tweets that reached over 53,000 people, focusing on energy savings, reduced costs, improved operations, and more:

  1. Guess how much of the world's energy is consumed by pumps.
  2. How can water technology improve energy efficiency?
  3. Is targeting the source the answer? How will renewable energy power improve water processing and distribution?
  4. Should there be more financial incentive for water utilities to reduce energy consumption?
  5. How can major savings be made with regards to water energy?

A3: Well looking at pumps which is a huge part of the energy consumption there are various parts of the equation #waterchat.

— Morten Riis (@mxriis) March 12, 2015

A3: Pump optimising: all in all, you should look at the TOTAL pump efficiency #waterchat#waterenergy

— Morten Riis (@mxriis) March 12, 2015

A3: Pump optimising 2:aim for higher ELECTRICAL efficiency–another vital part #waterchathttp://t.co/LYUr3csrDapic.twitter.com/mhzE5qAsHs

@mxriis#waterchat - definitely. Water conservation is the starting point. Reduce water use and you don't have to pump it!

— Andrew Shaw (@AndyRShaw2000) March 12, 2015

. @AndyRShaw2000 good point - another point: adress water loss #waterchat

@.waterworldmag: Opt Aeration is bottom aeration: 45-60 % of power consumption in #wastewater treatment is used on aeration (1/2) #waterchat

— Morten Riis (@mxriis) March 12, 2015

@WEX_Global Agreed. But we cannot give up on existing infrastructure that still has a long shelf life! #waterchat
