The Birmingham Township supervisors have approved the concept of community sewage systems in planned residential districts as part of a comprehensive sewage facility plan.
The township, which has been using the Chester County Master Sewer Plan drawn up for the Chester County Planning Commission, soon will have its own guidelines under the comprehensive plan.
The supervisors and two township Planning Commission members met Monday night to discuss changes in the plan. Fred Turner, a sewage consultant from SMC Martin Inc., consulting engineers of Valley Forge, answered questions and gave advice.
