Raleigh, NC, U.S.A. — (METERING.COM) — July 14, 2011 – There has been a 10 percent year-on-year increase in the planned or completed deployment of smart water systems, according to water utility representatives at the recent American Water Works Association’s (AWWA) ACE11 conference in Washington, DC.

In 2010 more than 60 percent were in some phase of smart water system deployment, but in the current year this number has risen to more than 70 percent.

These were among the findings of what is becoming an annual survey by Sensus at the event.

Among the other results of the survey, more than 80 percent of the respondents named life expectancy of smart meters and communication networks as the most important system selection criteria for a smart utility system, along with maintaining accuracy from low to high flow levels and over the lifetime of the meter.
Other important system selection factors included ease of installation and maintenance, manufacturer reputation, and utility peer recommendation, while additional top technology considerations included products constructed with lead-free materials, and strength of materials.

“Water utilities are increasingly adopting intelligent water management technologies to support long term conservation efforts and improve operational efficiency,” said Mike Tracy, executive vice president of Sensus North America.

The survey also revealed a year-over-year increase of more than ten percent (total 60.8 percent) of utilities ranking the ability for a smart water system to migrate from walk-by/drive-by to a fixed-base system as very important. There was also a greater than 10 percent increase (total 62.2 percent) in utilities concerned with technologies that could help reduce head loss, reinforcing the growing recognition of the relationship between water efficiency and energy efficiency.
