Energy Efficiency in Value Engineering: Barriers and Pathways
Value engineering is a technique that wastewater treatment facilities (WWTFs) currently use, when required, to analyze cost reduction and performance optimization opportunities. The research...
Water Utility Benchmarking
Benchmarking is essential for those developing and implementing water policy. If decision-makers do not know where they have been or where they are, it would seem to be impossible to set...
Characterizing the Quality of Effluent and Other Contributory Sources During Peak Wet Weather Events
This study evaluates the impacts of blending practices at municipal wastewater treatment plants on effluent and receiving water quality, and estimates public health risks associated with...
Non-traditional Indicators of System Performance
The use of real-time sensors and supervisory control and data acquisition (SCADA) systems has become commonplace in large centralized wastewater treatment systems. On-line sensors and SCADA...
Pathogen Risk Indicators for Wastewater and Biosolids
Direct analysis of potable water for pathogenic micro-organisms has generally been avoided by water suppliers because pathogens are frequently present intermittently and in low numbers. Direct...
Remaining Asset Life: A State of the Art Review
This report is an output of the fourth research track (Track 4) of WERF’s strategic asset management research program ‘Asset Management Communication and Implementation’ (SAM1R06). Track 4...
Decision Analysis and Implementation Guidance in Strategic Asset Management
Track 3 of WERF’s Strategic Asset Management Project was developed to “provide guidance on implementing SAM…and develop analytic tools for SAM implementation” - the Decision Support Tools and...
Strategies for Small Wastewater Systems for Risk Reduction and Safeguarding Assets
The Gulf Coast hurricanes of 2005 and horrific events of 9/11/2001 have spawned a new emphasis on domestic security and emergency preparedness. Governments at all levels are taking action to...
Assessing Infiltration and Exfiltration on the Performance of Urban Sewer Systems
Sewer systems constitute a very significant heritage in European cities. Their structural quality and functional efficiency are key parameters to guarantee the transfer of domestic and industrial...
Public Communication: Perceptions and Early Communications Tools
Public understanding leading to support for investment in aging water infrastructure is absolutely essential in order to close the “gap” between projected and current funding levels. In response...
