The corporate authorities find that:
A. There are no public sewers, no sewage disposal systems, and no provisions for the same, to serve any portions of the Village other than the Wynstone subdivision which has a self-contained system;
B. The soil conditions prevailing in the Village repeatedly have led to sewage disposal problems by the use of individual sewage disposal systems (septic systems) on small lots, particularly on lots of less than forty thousand (40,000) square feet in area, presenting a serious hazard to the health and welfare of the residents of the Village and surrounding areas; and
C. Said sewage disposal problems are increased by additional sewage disposal systems on lots of less than forty thousand (40,000) square feet in area in proximity to the other lots having individual sewage disposal systems (septic systems). (1977 Code § ZR-1-1)
