AWWA 2011 best paper award


The Engineering and Construction Division of the American Water Works Association (AWWA) is to award MWH Soft president and chief operating officer Paul F. Boulos, Ph.D., Hon.D.WRE, F. ASCE, the Division Best Paper Award at the AWWA Annual Conference & Exposition (ACE) 2011 World’s Water Event. The event will be held in Washington, D.C., 12th to 16th June.

Dr. Boulos wrote the award-winning paper with MWH Soft Client Service Manager Christopher M. Bros. He will be honoured during the Washington DC Annual Conference.

Titled 'Assessing the Carbon Footprint of Water Supply and Distribution Systems,' the paper describes a novel approach for calculating the carbon footprint of energy use in water distribution systems and introduces a new method for assessing distribution system efficiency. The new measure represents the energy efficiency of the entire network in conveying water from point of entry to the distribution system to the customer, in terms of potential energy converted to friction, discrete loss, and loss at the customer tap. It enables the water industry to conceive and formulate better-optimised decisions on potential energy savings aimed at reducing its carbon footprint, thus contributing to healthier air quality, minimising environmental impacts, and improving water efficiency and infrastructure sustainability.

Boulos said that water utilities are an indirect source of carbon emissions because of how energy is used in their water distribution systems. These systems can use a significant amount of energy to move water from one location to another via pumps; but they also lose energy during transmission (pipe friction), across valves (e.g., flow and pressure control), and at customer taps.

According to him, water utilities needed a measure for quantifying carbon footprint due to energy loss to help them minimise their environmental impacts by managing the overall carbon emissions of their water supply and distribution systems. MWH's new measure will assist water utilities worldwide in examining ways to reduce both their operating costs and carbon footprint, prioritise sustainable improvements, elevate their green credentials, and act as positive stewards of the environment.
