Treatment plants have been designed by F.E. Jordan Associates, Inc. in frequent association with other well known firms, as well as independently. These plants have utilized many treatment processes and have ranged in size up to 143 MGD. Our staff has experience in conventional systems and more recent technological improvements such as pure oxygen activated sludge, physical-chemical systems, advanced wastewater treatment, lagoons and land application.

    In addition to large projects, JA has experience in the design of smaller systems for communities that may require replacement of septic tanks or renovation of old or outmoded treatment processes.

    Whatever the project size, our firm has a commitment that in each assignment the design is developed to meet the special requirements that must be satisfied for that particular situation. A successful design requires the fusion of practical experience, the ready availability of the latest technology, and experienced and practical design talent to produce a functional and workable project.

    We approach each project with an open mind and no preconceived bias toward a particular treatment method, until an analysis of the individual situation can be made based on technology, cost and environmental considerations.

North Shore Sanitary District

Lake County, Illinois

201 Facilities Plan

    Jordan/Avent & Associates, in association with another consultant, is preparing a 201 Facilities Plan for the North Shore Sanitary District, Lake County, Illinois. The District currently operates three major plants with current total capacity of 55 MGD. In addition to the major plants, two pre-treatment facilities are operated for industrial wastes.

    The purpose of the facilities plan is to develop a recommended project for upgrading and expanding the existing facilities of the District to meet the wastewater treatment and disposal needs of the growing human population and industries estimated to be served by the District in the planning period to the year 2000. Consideration is being given to diverting wet weather overflows and effluent discharges from Lake Michigan.
