DC Water’s new headquarters in Washington DC (renderings from SmithGroupJJR and Skanska)

Today, the green energy technology company International Wastewater Systems Inc. (“IWS”) announced a $330,000 USD contract to install its innovative SHARC thermal energy exchange system to the new headquarters of the District of Columbia Water & Sewer Authority (“DC Water”) in Washington, DC, USA.

The new $60 million USD headquarters is being constructed on the waterfront of the Anacostia River in southeast Washington, DC, and will serve as the new public face for the agency. For IWS, it’s a major showcase project, potentially leading to more installations globally. DC Water’s green initiatives will be showcased in a deeply innovative facility featuring a bold and distinctive design developed by SmithGroupJJR, in collaboration with builder Skanska. While the building is designed to achieve LEED Platinum certification from the U.S. Green Building Council, it also employs many advanced strategies that will surpass LEED Platinum certification. According to InteriorDesign:

”Not only is the new headquarters anticipated to achieve LEED Platinum certification, it will utilize an innovative heating and cooling system in which wastewater will provide thermal energy to condition the building. Two-thirds of the city’s sewers pass through the site’s underground infrastructure, offering what SmithGroupJJR characterizes as a ‘virtually uninterruptible supply of thermal energy’, for what the firm says is the country’s first commercial use of the technology.”

The SHARC system will allow DC Water to use its own wastewater as a source of thermal energy to condition the building. This project represents an historic HVAC (“Heating, Ventilation and Air Conditioning”) first. The new DC Water headquarter building will be the first ever deployment of this technology used to both heat and cool a building in the USA. Utilizing this technology, the design team has calculated that the new headquarters will take its place as one of the lowest energy-consuming office buildings in the region.

The project promises to be DC Water’s “most sustainable construction project ever” (quote from the Washington Business Journal; renderings from SmithGroupJJR and Skanska)

SHARC (pictured above) is a large, custom-designed water heating and space conditioning system with a capacity of 440-880 kW, which can be scaled to serve large district heating networks by adding multiple SHARCs. SHARC installations are individually designed and engineered for industrial, commercial and >200 unit residential applications.

IWS will install the SHARC 440 model with a flow rate of 250 gallons per minute, providing the primary energy source for building heat, and the primary energy rejection source for building cooling.

IWS’ SHARC technology is a major contributor to the project’s LEED® Platinum 96 credit threshold, delivering one of the lowest energy consumption rates per unit of floor area possible, while reducing greenhouse gas emissions by over 40%, and water consumption by hundreds of thousands of gallons annually.

Don Posson, SmithGroupJJR’s Corporate Director of Engineering, commented in today’s press-release:

“The idea of building a 150,000-square-foot headquarters building directly over a pumping station would normally be viewed as implausible. But by doing so, DC Water will be able to leverage the station’s wastewater to provide enough power to heat and cool this large building. It’s a breakthrough solution and a perfect complement to DC Water’s objective of a greener, healthier District of Columbia.”

Lynn Mueller, CEO of IWS, added:

“DC Water’s new state-of-the-art building is a world class design-build project. The integration of SHARC technology demonstrates the world-class caliber of IWS’s projects and partners, and represents the increased adoption of IWS systems in the United States.”

Project Description from the architects:

“DC Water, Washington DC’s metropolitan water and sewer authority, sought to create a new headquarters facility to consolidate its administrative functions with flexible and functional office space, while being an example of state-of-the-art sustainable design. It selected a site it already owned in a burgeoning new neighborhood in the District: acreage along the Anacostia River containing the 1960’s O Street Pump Station and the adjacent Historic Pump Station. Because two-thirds of the metro area’s sewer outflow passes through the two stations, it was imperative the facility remain operational and accessible throughout construction. What’s more, virtually all the below-grade surface area houses massive and fragile clay infrastructure that was more than 100 years old.

Developed as a design-build collaboration between SmithGroupJJR and Skanska, the new headquarters design arcs along the riverfront with a bold glass and aluminum curtain wall partially supported by a 200-foot-long, four-story truss in order to isolate it from the existing 1960’s pump station.The building’s lobby doubles as an interpretive center, where visitors can clearly see portions of the pumping station at work and learn about the building and site’s many sustainable features. An innovative heat recovery/rejection system utilizes heat from the pumping station’s wastewater treatment operations to condition the new building, making it one of the most-energy efficient office buildings in the Mid-Atlantic region. A 30,000-gallon cistern captures rainwater for onsite reuse. Tinted glass sun shades provide passive shading in strategic locations and reduce energy use while maximizing daylighting and the panoramic river views. In all, the new headquarters provides an outstanding work environment, while embodying and expressing best practices in environmental stewardship.”



The District of Columbia Water and Sewer Authority (DCWASA) was created by District law in 1996, with the approval of the United States Congress, as an independent authority of the District Government with a separate legal existence. In 2010 the Authority rebranded and became DC Water. DC Water provides more than 681,000 residents and 21.3 million annual visitors in the District of Columbia with retail water and wastewater (sewer) service. With a total service area of approximately 725 square miles, DC Water also treats wastewater for approximately 1.6 million people in neighboring jurisdictions, including Montgomery and Prince George’s counties in Maryland and Fairfax and Loudoun counties in Virginia.

During Fiscal Year 2016, DC Water pumped an average of more than 99 million gallons of water per day. In addition, DC Water stores 61 million gallons of treated water at its eight facilities. The Washington Aqueduct stores an additional 49 million gallons.DC Water delivers water through 1,350 miles of interconnected pipes, four pumping stations, five reservoirs, three water tanks, 43,860 valves, and 9,510 fire hydrants. DC Water operates 1,900 miles of sanitary and combined sewers, 160 flow meters, nine wastewater pumping stations, 16 stormwater pumping stations, 12 inflatable dams and a swirl facility. (Source)
