The starting point for developing a successful wastewater system is a wastewater audit, which would
identify the expected wastewater streams from each medical and service area of the health-care facility, and provide
data for pretreatment, collection and treatment arrangements for wastewater to be developed. A maintenance plan
to cover both corrective and preventive maintenance should also be prepared. If an onsite treatment plant exists, it
must be included in the operations and maintenance plans, and a budget allocated to sustain operations.
