U.S. progressive wastewater treatment plant

Acclaimed Portland-based architecture firm Skylab Architecture worked with Contractor Skanska USA Building to complete yet another impressive sustainably designed building.

The Columbia Boulevard Wastewater Treatment Plant is a new 11,490 square-foot (1,067 square-meter) facility that will provide office space for 36 engineers and a visitors reception area for public interface.

This design not only employs clean modern design, but it also channels stormwater through a green roof system, making it out as one of the most progressive facilities of its kind.

The Columbia Building is an educational demonstration of sustainable building techniques. Designed in a radial fashion to track the sun, this single-story concrete building folds seven cast-in-place concrete roof forms to channel the stormwater down a green roof system into a swale and back into the Columbia Slough.

The saw-tooth roof form also allows for the building to be flooded with natural light, while the jagged façade has a series of stainless steel solar shades over the clerestory windows to modulate the light throughout the day.

Skylab Architecture’s design was “inspired by native landscape and its industrial past … (and) is an elegant combination of landform, indigenous planting, formal geometry, and durable construction systems”.

Other sustainable systems included in this elegantly dynamic design include a heat pump mechanical system that taps into the plant’s processing water source for heating and cooling, a photovoltaic system, an onsite co-generation plant, and a central green space.

Skylab Architecture provided the City of Portland Bureau of Environmental Services with a wonderfully scaled facility that adds creativity and public education to the wastewater service industry.
