Prior to submitting your project, you may request an early assistance meeting by contacting a Project Manager at 847.377.2600. Early assistance meetings are provided at no charge, and the meeting will be coordinated by a Project Manager to ensure all involved Lake County departments are present to address your proposed project. The meeting will identify project requirements and design issues before the project begins. The meeting may offer guidance on the best use of a complicated site. Minutes from the meeting will be provided for your use in design, layout and/or calculations that may be required for your proposal.
The Onsite Wastewater Treatment System offers a wide array of services used in siting, planning, and installation of septic systems. The Health Department trained staff of environmental health practitioners, soil scientists, plan reviewers, and administrators facilitate the communication process in the regulation of OWTS permits between the homeowner, design engineers and septic contractors.
