Abstract

Plastic pollution is a problem and the world is currently dealing with its impacts on the aquatic environments. This study investigates the perceptions and knowledge of process controllers and managers from twelve water and wastewater treatment plants within two local municipalities (Thulamela and Makhado) in the Vhembe District Municipality, South Africa. The perceptions and knowledge of plastic pollution, limited resources and economic difficulties, the effects of plastic pollutants on water systems, a lack of information and training, and a lack of institutional support documents were the five main themes that were identified from semi-structured interviews with workers from the treatment plants. The findings show serious issues regarding plastic waste affecting treatment operations, ineffective methods of removing plastics and inadequate waste collection services in rural areas. Financial and material limits make managing plastic pollution even more difficult, and inconsistent training and a lack of institutional support make it difficult for workers to manage it consistently. The responses highlight the need for improved waste management plans, financial support for advanced filtration systems, and continuous training to provide workers with the skills and knowledge needed to reduce plastic pollution. These measures are crucial for maintaining the water quality and increasing treatment plants’ operational effectiveness.
