Waste design and source control lead to flexibility in wastewater management

The concepts of waste design and source control are introduced as contracts between wastewater handling agencies and consumers and consumers and industry respectively. Waste design serves to produce waste streams that are optimized in composition and time sequence for easy transport and treatment. Source control makes services and installations available, which allow the consumer to adhere to the specification of waste design. Increased delegation of responsibility to the consumer is expected to result in more flexible wastewater handling systems.
