NARRATIVE: The Glenbard Wastewater Authority is located in Glen Ellyn, IL, and serves the Villages of 
Glen Ellyn and Lombard, as well as other surrounding unincorporated areas.  The design average daily 
flow is 16.02 MGD with a peak flow of 47 MGD, and a population of approximately 109,125 being 
served.  The main treatment plant consists of preliminary treatment, primary treatment, high purity 
oxygen activated sludge process, tertiary filtration, and UV disinfection (seasonal).  The Authority also 
owns a remote Combined Sewer Overflow (CSO) facility that is only operated during wet weather.  The 
CSO facility consists of preliminary treatment, primary treatment, and disinfection.  The majority of the 
Authority’s service area consists of separated sanitary sewer, however some portions of the collection 
system are combined sewers, which created the need for the CSO facility.    

The Glenbard Wastewater Authority fosters the attitude that we are no longer a wastewater treatment 
facility, but instead a resource recovery facility, as the influent water we receive has many valuable 
resources that can be recovered.  While the Authority’s official motto is “Protecting the Environment for 
Tomorrow,” one of the main initiatives of the Authority is to become a net zero facility. Some of the 
many benefits of striving to become net zero are the positive environmental impacts, as well as the 
ability to minimalize increases in rates to customers.  Instead of solely collecting wastewater and 
cleansing it to meet permit limits prior to discharge to waterways, the Authority strives to transform 
itself into a manager of valuable resources, a partner in local economic development, and a member of 
the watershed community seeking to deliver maximum environmental benefits at the least cost to the 
society.  It does this by reclaiming and reusing water, examining the benefits of extracting nutrients and 
other constituents, capturing waste heat and latent energy in biosolids and liquid streams, generating 
renewable energy using biosolids, and using green infrastructure to improve urban quality of life.    

The Authority promotes an organizational culture in order to become a utility of the future today.  Some 
of the many ways the Authority accomplishes this are through the involved and well-organized senior 
leadership team, actively engaging employees to improve upon inefficiencies as well as share ideas,
