Water efficiency is reducing water wastage by measuring the amount of water required for a particular purpose and the amount of water used or delivered. Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use.

Rainfall, Nutrients, and the Dead Zone

A few weeks ago in this space, I mentioned the algae blooms plaguing Florida this year, largely the result of nutrient-rich water being released from Lake Okeechobee. Unfortunately, it’s not just Florida that’s experiencing the problem—there’s plenty to go around.

A recently published study in Science shows that excess nutrients

The Art of Leak Detection and the Arithmetic of Audits

According to EPA, public systems face numerous challenges, including aging infrastructure, increasing regulatory requirements, water quantity and water concerns, and inadequate resources. These challenges are amplified through changes in population and climate. It is estimated that the US will need to spend upwards of $200 billion on water systems in

How to Educate the Public About the Benefits of AMI

How to Educate the Public About the Benefits of AMI

In recent years, municipalities and utility companies have endeavored to learn how to capture, access, and manage data provided by Advanced Metering Infrastructure (AMI). Now, they have another challenge: Teach the public about the benefits of AMI.

“There’s confusion about what AMI is,” postulates Robb Barnitt, CEO of Dropcountr.com, a software

Squeezing Water From the Sea

Squeezing Water From the Sea

By forcing salt water against polymer membranes that trap salt ions and allow fresh water through, reverse osmosis (RO) desalination is an effective water treatment technique. It is relatively expensive, however, due to the energy used to push water molecules through the membrane. But a remarkable facility in Israel, is

The Inland Empire Utilities Agency (IEUA/Agency) is a regional wastewater treatment agency and wholesale distributor of imported water. The Agency is responsible for serving approximately 875,000 people over 242 square miles in western San Bernardino County, which is located about 30 miles east of Los Angeles in southern California. The

It’s Manslaughter

Last week, as you’ve probably heard, five people in Michigan were charged with involuntary manslaughter for circumstances related to the Flint water crisis—specifically for their failure to sound the alert about increases in the number of cases of Legionnaires’ disease. It’s believed that pipes corroded by the city’s new source

A Rate Structure Rubik’s Cube

Water agency rate structures typically recover costs by charging consumers per gallon, which means that when usage drops, rates have to go up. In many cases, that means that it costs rate payers more to conserve water.

The financial logic is simple. If a company sells less of something, it has

Global Awareness and Grace

In an effort to better understand women’s participation in the water industry and the water supply network, last May Water Efficiency magazine explored the topic by way of an interview with Kirsten deVette of the International Water Association.

We learned that in many parts of the world women bear the primary responsibility for

Embracing Water Audits

Embracing Water Audits

Water remains a scarce resource throughout the country. But it’s important, even for utilities that aren’t serving drought-stricken areas, to make sure that they are getting paid the right amount for the water they are delivering. It’s important, too, that they quickly identify and repair costly leaks throughout their systems.
