Wwt Award

Sioux Center’s Wastewater Treatment Facility is receiving high recognition for innovative design and construction.


The City of Sioux Center, along with engineering firm Bolton & Menk, Inc., won an Outstanding Civil Engineering Award for the Sioux Center wastewater treatment facility, awarded by the American Society of Civil Engineers (ASCE) - Iowa Section.


The selection process for this award considers contribution to the well-being of people and communities, resourcefulness in planning and in solution of design problems, pioneering in the use of materials and methods, innovations in construction, consideration of impact on environment, unusual aspects, and aesthetic values. The honor is given for the achievement - not to an individual - so that the project owners and the many engineers who worked on the project are collectively recognized for their contributions.


Sioux Center Wastewater Department Head Zeke Ellis says, they strive to achieve excellence through cooperation and progressiveness, and he says this project represented both of them through coordination with the community, city and the engineering firm.

The $25 million Wastewater Treatment Facility was completed in 2019. It was designed and built to meet new, more stringent DNR standards and replace Sioux Center’s former aging plant.


Sioux Center Utilities Manager Murray Hulstein says they took a comprehensive approach to evaluate the facility and its impacts on the environment during the planning phase.  He says the engineers and the city worked together to develop a plant to serve flows and loadings for the design year 2040.”


The new facility employs different methods that allow it to treat the water to a higher standard and produce a cleaner effluent than the previous plant. It can treat an average of 2 million gallons daily and serves more than 2,500 residential, commercial, and industrial customers.
