Maintenance and Operations Department
  The Maintenance and Operations Department consists of four divisions, three of which are field divisions that relate logistically to the District's 872 square mile service area, and a centralized General Division that provides administrative support throughout the Department in terms of financial, budgetary, contract preparation/payment, managerial and investigative services. While each division has provided a separate narrative highlighting individual areas of responsibilities, challenges and accomplishments, M&O, as a Department, is responsible for the following:
Protecting the water quality of Lake Michigan, which serves as a source of drinking water throughout the Chicago greater metropolitan area;
Collection of wastewater discharge from a population equivalent of 10.1 million people (domestic use and industrial discharge) through a complex network of intercepting sewers and the Tunnel and Reservoir Plan (TARP);
Treatment of approximately 530 billion gallons of collected wastewater at the District's seven water reclamation plants;
Maintenance and operation of the District's collection/treatment facilities, which include: seven water reclamation plants, 554 miles of intercepting sewers with approximately 430 controlled connections, 23 remote pumping stations, 109.4 miles of TARP with approximately 151 controlled connections, 5 Side Stream Elevated Pool Aeration Stations (SEPA), and 32 retention reservoirs;
Removal, processing, beneficial reuse and environmentally safe utilization of biosolids, which are a product of the water reclamation process;
Minimize local area flooding and pollution through monitoring and active control of the water levels in 76 miles of rivers and canals, as well as the area's 32 retention reservoirs;
Improvements in the quality of water in the Chicago area waterways through minimization of pollution load discharged to the waterways, removal of debris in the water and operation of 5 SEPA stations and two Instream Aeration Stations which add a significant amount of oxygen to the water;
Proactive management of energy costs through innovation, such as: maximization of off-peak pumping, voluntary curtailment of electric use during peak periods, collection/use of methane gas, and use of turbines and micro-turbines to generate electricity at the Stickney WRP to improve operational efficiency and thereby increase the District's direct energy credit received from the utility company.
