A. Prior Proposal Review. Upon the applicant’s request, the Health Authority will review any proposal for a private sewage disposal system to serve non-residential property via an informal meeting with the designer prior to its submittal for approval. The review shall consider those elements of the proposal which may impact the functioning and longevity of the private sewage disposal system including but not limited to waste strength, peak flows, removal of non-domestic wastewater, seasonal flow variations, soil or site limitations, adequate future replacement area, and elements of the proposal which may require special arrangements for access or maintenance. Wastewater constituents of concern are dependent upon the anticipated waste stream and include but are not limited to total suspended solids, fats, oils and greases, nutrients (i.e. nitrates, chlorides, phosphates) and biochemical oxygen demand. The prior proposal review fee is approved by the McHenry County Board and is contained in the Public Health Fee Ordinance.
B. New Non-Residential Properties. All non-residential properties, constructed after the effective date of this Ordinance; and served by private sewage disposal systems shall meet the following requirements:
1. Metered Water Usage. A water meter shall be installed on the water supply. The water meter shall measure water usage in increments of gallons or tens of gallons.
2. Monitoring Water Usage. The property owner shall monitor and record the water usage daily. These records shall be kept available for Department review.
3. Peak Domestic Wastewater Flows. Domestic sewage flows shall not exceed the design capacity of the private sewage disposal system.
4. Department Inspection and Sampling. Random inspection and/or sampling will be accomplished by the Department to ensure compliance with this Ordinance. Sampling will include, but not be limited, to BOD-5, suspended solids and pH.
5. Type of Waste. Domestic sewage flows only are to be discharged into these types of systems.
C. Existing Non-Residential Properties. All non-residential properties, constructed prior to the effective date of this Ordinance; and served by private sewage disposal systems shall adhere to the following:
1. Peak Domestic Wastewater Flows. Domestic sewage flows shall not exceed the design capacity of the private sewage disposal system.
2. Department Inspection and Sampling. Random inspection and/or sampling will be accomplished by the Department to ensure compliance with this Ordinance. Sampling will include, but not be limited to, BOD-5, suspended solids and pH.
