A. Individual septic systems or sewerage systems designed to dispose of effluent by subsurface soil absorption methods are generally not suited for multifamily construction because of maintenance problems. Satisfactory operation can be expected only under unusually favorable soil conditions. When these methods of sewerage disposal are proposed, an environmental (sanitary) engineer, with no other interest in the project, should be hired by the Borrower to investigate soil and site conditions and make recommendations. A copy of the report must be available to the Project Architect and be included in the exhibits submitted for review by the Lender’s Construction Analyst. When an existing property relies on a septic system, the Lender and Needs Assessor must conduct an intrusive examination by a qualified third party (environmental or sanitary engineer) who must investigate the maintenance history of the septic system and recommend current and future repairs, alterations, or replacements needed to assure continued satisfactory operation. An Operations and Maintenance Plan must be prepared as guidance to management and tenants on routine care and maintenance of the septic system
