Past Events:

Water Treatment Plant Tour on February 21

Attendees toured the state-of-the-art WSSC Potomac Water Filtration Plant in Montgomery County, Maryland. This facility, which produces 280 MGD, showcases the latest innovations in water treatment technology. The intricacies of the upgraded processes that contribute to remarkable capacity, including cutting-edge filtration techniques and enhanced efficiency measures, and in-depth explanations of the engineering marvels behind each process, from intake to distribution, were presented. In addition to the plant-specific information, the tour covered general aspects of water treatment, addressing key challenges, sustainability practices, and future developments in the field. 

Pipeline Workshop on November 9

This half-day pipeline management workshop highlighted case histories on pipeline condition assessment and design-build pipeline rehabilitation as well as a panel discussion with audience participation. Speakers included representatives of Baltimore City DPW, Structural Technologies, and HDR.

Maryland Pipeline and SUE Workshop on March 30

The free, half-day workshop highlighted an interesting look at the history of PCCP, an interactive panel comprising Brian Ball, P.E., Chief of the Office of Asset Management for City of Baltimore, Daniel Davis, Chief of Howard County DPW's Utility Design Division, Mike Mazurek, former Chief of Water Design for Baltimore County DPW's Bureau of Engineering and Construction, and Chris Phipps, P.E., former Director of Anne Arundel County DPW who discussed pipeline break management, and a presentation of the new ASCE SUE standard 38-22. 

Covid-19 Financial Impact on Utilities 

Webinar on January 26

Patti Colihan, Chief Financial Officer of WSSC Water, addressed the pre-pandemic fiscal challenges, the additional challenges caused by the pandemic and the financial plan that was executed to maintain solid financial position in the face of declining revenues and growing past due customer accounts at WSSC. Patti also shared about a number of innovative projects.

Recognizing that COVID impacted DC Water in many ways, Matthew Brown, Chief Financial Officer and Executive Vice President of Finance and Procurement for DC Water, talked about steps taken to protect employees and how customers were prioritized. Even though DC Water experienced a decline in revenue from reduced consumption and increased customer delinquencies, DC Water is advancing initiatives to improve equity by expanding customer service and ridding the District of lead service lines.

Aerial Sewer Crossing Workshop on November 17

An aerial sewer crossing Hickey Run in the National Arboretum, is one of many that DC Water owns and operates in Washington, DC. Inspections revealed not only spalled concrete, but also a compromised foundation at the upstream abutment; crews discovered an eroded void beneath the footer and the exposed backside where it is subject to surge flow of the creek along the eroded embankment.

DC Water recommended an emergency repair in lieu of planned CIP, with the blessing of the Department of Energy and Environment of DC for a “permitting later and urgent repair first” special green light. 

DC Water representatives and Structural Technologies experts detailed the components of the emergency design-build repair and how DC Water implemented a comprehensive asset management approach to extend the life of this critical asset.

WSSC's Water Pipe Forensics Program webinar on July 22

This event was a joint effort with the ASCE MD Geo-Institute.

WSSC Water has initiated a forensics program to collect, evaluate, and analyze pipe failure data. Data are used to establish correlations and identify trends to minimize future failures through improved design standards, construction practices, and replacement and rehabilitation planning. The program focuses on cast and ductile iron pipes which make up 85% of the WSSC water distribution system. Key components of the program include laboratory and field testing of samples, development of GIS database, failure analysis, and evaluation to support condition assessment efforts and asset management initiatives as part of the WSSC Asset Management Program and water main replacement and rehabilitation planning. Some parameters considered in the evaluation include soil conditions, groundwater table, and material composition and age of pipe. This presentation shared the process used for evaluation and walked though some of the preliminary results.

Presenter Haile Yerdaw, P.E., PMP, is the Civil Engineering Section manager under the Engineering and Construction Department in WSSC. Haile has 18 years of experience in civil engineering design, construction and project management. In his capacity as a section manager, he oversees several programs including pipe forensics, corrosion management, dam inspection, Fiber Reinforced polymer rehabs for large diameter pipes, and in-house design review of civil engineering projects. 

Presenter Rosanna La Plante, PE, is a Division Manager for WSSC. Rosanna leads the Engineering and Environmental Services Division, overseeing land services, civil engineering support, contract services, GIS and engineering records, mechanical and electrical engineering support, environmental programs, and environmental services.
