Past Events:

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.
