City of Baltimore implements enhanced treatment facilities at Back River, their largest Waste Water Treatment Plant.

The City of Baltimore Department of Public Works owns and operates two of the largest water resource recovery facilities (WRRF) in Maryland with a combined treatment capacity of nearly 250 million gallons of dry flow per day. Both facilities have recently implemented advanced treatment technologies to further reduce discharge of nitrogen and phosphorus (“nutrients”) to the receiving streams, as part of the Chesapeake Bay Program’s goal to improve the health of the Bay and the water quality in the Chesapeake Bay watershed.

The Back River Wastewater Treatment Plant Enhanced Nutrient Removal Upgrade involved the integration of 52 of some of the world’s largest denitrification filter cells into the existing plant, which was originally built in 1911. These filter cells were specifically designed for this project. Results show the technology reduced the nitrogen and phosphorous load discharged into the Bay by nearly 2 million pounds in its first year of operation. This project was awarded the 2019 Outstanding Civil Engineering Achievement Award from the Maryland Section of ASCE and the 2019 National Grand Award by the American Council of Engineering Companies (ACEC).

At the larger of the two facilities, the Back River WRRF, the City is also now midway through a major construction program that includes new facilities to handle wet weather flows to the plant. This program is part of the City’s Wet Weather Consent Decree by EPA and requires elimination of sanitary sewer overflows (SSO), reduction of inflow/infiltration (I/I), sewer system rehabilitation and improvements to the conveyance capacity. The total construction cost for the nutrient removal upgrades and the wet weather facilities is nearly $1.2 billion.

Please join the National Capital Section on Thursday, September 12, 2019, as Per Struck presents on:

  • A brief overview of the City’s phased construction program
  • Design, construction and startup of the $500M+ enhanced nutrient removal upgrade at Back River WRRF

At this meeting, we will also be inducting our NCS Officers and Directors for the 2019-20 Section year.

WHEN: Thursday, September 12, 2019, 6:00 PM - 8:30 PM. Registration and networking will be from 6:00-6:45pm, followed by dinner. Program concludes by 8:30pm

What is ASCE-NCS?

Welcome to the website of the National Capital Section of the American Society of Civil Engineers (ASCE), a professional society for civil engineers.  ASCE was founded in 1852, represents 130,000 members of the civil engineering professional worldwide, and is America's oldest national engineering society.

The National Capital Section was founded in 1916 and currently has more than 3,100 members.  The section is located in Region 2 (link to region 2: http://region2.asce.org/). The National Capital Section serves the District of Columbia; the counties of Montgomery and Prince Georges in Maryland, except College Park in Prince Georges County; the counties of Fairfax and Arlington, and City of Alexandria in Virginia. The National Capital Section's mission includes:

  • To advance the professional knowledge and improve the practice of civil engineering for our members and those we serve.
  • To advocate for our profession with those whose actions affect us, and to educate those whose actions and responsibilities could benefit from a better understanding of the contributions of civil engineers.
  • To improve our community through effective community outreach programs, local involvement and educational efforts.
