Potomac Main Inspection

Project Overview

As part of the Washington Suburban Sanitary Commission’s ongoing effort to provide you with quality service while we repair our aging infrastructure, WSSC will inspect and, where necessary, repair and replace sections of a 72” and a 66” water main running between I-270 where it crosses Tuckerman Lane and Sligo Creek in Montgomery County.

The inspection process is designed to have as little impact on the community as possible. We do not anticipate any interruption of your service at this time. However, because we are inspecting 6.4 miles of pipe, there is the potential that several sections of the pipe will need to be repaired or replaced.

WSSC is working closely with regulatory agencies to deliver a high-quality project on time, while minimizing disruptions to the community. When it is determined that a section of the main needs replacement, contractors will be brought in immediately to work around-the-clock to replace the section as quickly as possible.

Because the pipe sections substantial in size, the work required will cause some inconveniences when it comes to noise, traffic and illumination. Wherever WSSC alters the landscape, we will dedicate ourselves to returning the affected areas to their original condition.

If you have any questions or concerns, please contact our 24-hour emergency service number at 301-206-4002 or 1-800-634-8400. You can also receive updates on the project’s progress via e-mail. Simply send an e-mail to WSSC’s Communications and Community Relations Office at communications@wsscwater.com with “72”/66” Potomac Main Inspection” in the subject line.

Major Construction Projects and Studies

Bi-County Water Supply Main Alignment Study: The Clean Water Connection

As part of the Washington Suburban Sanitary Commission’s (WSSC) ongoing efforts to provide our customers with a constant, reliable supply of safe, clean drinking water, we are pleased to inform you that WSSC will start a comprehensive alignment study this fall of a Bi-County water main project. The Bi-County water supply main is approximately 5.5-miles of 84-inch diameter water main connecting an existing main at the intersection of I-270 and Tuckerman Lane to another main in the area where Rock Creek crosses I-495 in Montgomery County. The new supply main will help transport clean drinking water from WSSC’s Potomac Water Filtration Plant (WFP) to eastern Montgomery County and most of Prince George’s County. The Potomac WFP produces approximately three-quarters of the water used by WSSC’s 1.6 million customers. The new supply main will alleviate capacity limitations from an existing 54-inch diameter main that delivers water from the Potomac WFP to the existing 96-inch diameter main at Rock Creek and I-495. Learn more about this important study.

Potomac Improvement Projects

The safety of drinking water is one of the most important public health issues in any society. As an agency dedicated to public health, WSSC is proud of our history of providing our customers with safe, clean drinking water -- water that meets or surpasses strict federal US Environmental Protection Agency (EPA) standards. Working to ensure continued superior water quality, WSSC is embarking on several improvement projects at our Potomac Water Filtration Plant designed to enhance plant efficiency and reliability; provide access to a cleaner, safer, more stable raw water supply; and accommodate future water needs of our customers. The following links provide more informationabout our efforts to supply you with safe, reliable water for decades to come.

Cabin John Sewer Basin Study

Using state-of-the-art technology, WSSC is capturing data on rainfall, wastewater flows, the conditions of pipes and manholes and areas where sewer mains have become exposed due to erosion in creeks and streambeds in the Cabin John sewer basin. Learn more about this four-year study.

Beaverdam Branch Sewer Basin Study

Using the latest Geographic Information Systems (GIS) technology, WSSC is capturing data on wastewater flows, rainfall, the conditions of pipes and manholes and regions where sewer mains have become exposed due to erosion in creeks and streambeds in the Beaverdam Branch sewer basin. Learn more about this three-year study.

Water Reconstruction Program

This program consolidates several water main improvement activities designed to enhance water quality, pressure and reliability under one initiative and strategically targets funding to upgrade and/or replace aging water mains in Prince George's and Montgomery Counties. The majority of funding is dedicated to replacing older water mains previously prone to breaks with new sections of cement lined ductile iron pipe. Projects also could include cleaning and lining older water mains -- removing corrosion on the inside of cast iron water mains and lining the interior of the pipes with cement mortar. To view current water and/or sewer main improvement projects, please view our News Releases. For more information on our Water Reconstruction Program, or to find out if the water mains in your community meet the criteria for this program, please call Ana Debevoise at (301) 206-8562 or email: adebevo@wsscwater.com.
