Wastewater Treatment Plants (WWTPs): The District owns and operates three major wastewater treatment plants: Easterly, Southerly and Westerly. Through the operation of these plants, the District minimizes the amount of pollution entering Lake Erie and the Cuyahoga River.
Interceptor Sewers: The District is also responsible for a variety of related wastewater treatment infrastructure and projects, designed to provide wastewater conveyance from the local sewers to the treatment plants. The District maintains over two hundred miles of large interceptor sewers.
Combined Sewer Overflow Control: The City of Cleveland and some nearby suburbs have combined sewers, in which one pipe conveys both stormwater and sanitary sewage. The District maintains combined sewer overflows throughout the Greater Cleveland area.
Industrial Waste Control: The District conducts investigations to identify pollutants within the sewage collection system that have the potential to be reduced through pollution prevention and works with industrial customers to achieve pollution prevention goals.
Other Areas: Other District activities include watershed protection and planning, working with local communities to ensure that small streams and tributaries are properly maintained.

A wastewater collection system gathers used water from homes and businesses and directs it to the conveyance system. Some of the components of a collection system include: gravity sewers, force mains, manholes, regulators and lift stations. Proper maintenance of the collection system ensures that wastewater is not allowed to back up and overflow into the street, someone's home, or into the streams, rivers or Lake Erie.

Conveyance of wastewater is achieved through a system of local sewers, combined sewers, intercommunity relief sewers, interceptor sewers, automated regulators and pump stations. Proper operation and maintenance of the conveyance system ensures that wastewater is safely and efficiently transported to treatment plants.

Wastewater treatment cleans up water so that it may be safely released to a lake or river, and it usually consists of two major stages - primary and secondary. Primary treatment separates sand, grit and larger solids from the wastewater, but solids still remain. Secondary treatment removes these solids mainly through a biological process.
