XylemKnowsH2o is the social media component of Xylem – Applied Water Systems. We are here to discuss the world’s water issues. With innovative systems in almost every area of water handling, control, treatment and distribution, Xylem is deeply involved in the cycle of water.

We are focused on producing highly efficient products and systems that use less energy and provide environmental benefits to users and the communities in which they operate. Come, join the conversation – Let’s Solve Water…

Read My Lips: Energy Efficiency is Here to Stay

Energy Efficiency Fast-forward 20 years and you have that same efficient systems groundswell of support rejuvenated. Terms like “green” and “carbon footprint” have littered this industry’s landscape — in a good way.

What’s Your Water Conservation Strategy?

“Do you conserve water?” That was the headline of an online article I recently read. But what grabbed my attention was the date of the article – August 1963. That was 47 years ago.

The Lost Art of Steam Heat: It’s Not Dead Yet

Guest blogger Dan Holohan writes about the Lost Art of Steam Heat. Lots of talk about low-hanging fruit lately – those things we could do to improve the efficiency of America’s older heating system, without having to knock the place down and start anew.

Pumps, Pipes, and Pads

As much as we all love pumps, we have to admit they’re pretty useless unless they’re connected to pipes on the suction and discharge sides. And, of course, pumps need to be properly anchored if you want to avoid noise, vibration, leaks, and lawsuits. So, without further adieu, here are some tips for connecting pumps to pipes and pads.

Time is Running Out for Uncle Sam To Put Some Money in Your Pocket

It’s mid-way through November and this is a good time to remind building owners that they only have a few weeks left to get federal tax credits up to 30% of the cost of qualifying energy-efficient products and/or system upgrades. These rebates apply to upgrades to heating and air conditioning units, water heaters and qualifying products purchased by December 31, 2010 deadline.

Rightsizing = Green Design & Operations

As we all know, pumping less water in a hydronic system is an easy way to save money on monthly bills. In existing buildings and new buildings, you’ll find that engineers often opt to overdesign systems, leading to too much water in systems. In existing buildings, to reduce energy costs, there’s a tendency for operators to reduce water flow, but not always in the best ways. So here are some tips to optimize water flow for new and existing buildings.

Cavitation: A Case of Nasty Bubbles

The popping, hissing, swishing and crackling noises you may have heard coming from a pump is cavitation — bubbles created from too much vapor in the hydronic loop that are collapsing and causing pressure waves to strike interior pump surfaces.

What is the Value of Water in Our Daily Lives?

Water is a constant in our daily lives. We need it to drink, cook and clean. We need it for sanitation, fire protection, watering our lawns and washing our cars. We need it to live. Even so, it’s easy to take water for granted.

LEED and Water Efficiency

As most water pros know, LEED is a point-based system administered by the U.S. Green Building Council, with points awarded for meeting the specific requirements of credits in each of the categories.

The Importance of Industry Certification

Whether it is the certification of individuals, products or processes, certification confers an array of valuable benefits to the individual or company, the sanctioning professional group, and to the marketplace in general.
