All proposed sanitary sewer facilities shall comply with the regulations of the Illinois Department of Public Health and the Illinois Environmental Protection Agency, and with all pertinent requirements of the subsections below. Sewage collection lines shall not be smaller than eight inches in diameter.
(A) When public system available. Whenever the public sanitary sewer system is reasonably accessible (that is, whenever the distance from any boundary of the subdivision to the nearest public sewer with available capacity does not exceed 600 feet), the subdivider shall extend the public system throughout the subdivision and provide each platted lot with a connection thereto at the lot line.
(B) When public system planned. In areas where the public sanitary sewer system is not reasonably accessible but where plans for the installation of the system have been approved by the Illinois Environmental Protection Agency, the developer shall provide sanitary sewers and lateral service lines in accordance with such plans and temporarily cap them until such time as the public sanitary sewer system becomes available.
(C) Private central sewage system. Except as provided in division (D) below, whenever the public sanitary sewer system is not reasonably accessible, the subdivider shall install a private central sewer system in conformity with all applicable regulations of the county and the Illinois Department of Public Health in effect on the effective date of this chapter or as amended hereafter.
(D) Individual disposal systems. Individual sewage disposal systems, such as septic tanks or aerobic treatment systems, shall be permitted only when the public sanitary sewer system is not reasonably accessible. If permitted, all individual sewage disposal systems shall be designed and installed in conformity with all applicable regulations of the county and the Illinois Department of Public Health in effect on the effective date of this chapter or as amended hereafter. When individual sewage disposal systems are permitted, the Administrator may require that the minimum lot size be increased above usual zoning district requirements as necessary to meet the applicable regulations of the county and the Illinois Department of Public Health.
