The wastewater contains for example: sanitary products, hair, grease, pharmaceutical residues etc. also the purification of the wastewater requires large investments. The aim of this study was to investigate the wastewater treatment plants (WWTP) communication methods to reduce the emissions from households to wastewater treatment plants. The study was made by a literature review and an interview survey involving four WWTP: Stockholm vatten och avfall AB, Kalmar vatten AB, Vatten & Miljö i Väst AB and Laholmsbuktens VA. WWTP use several different communication methods such as websites, social media, study visits and campaigns. Because of limited time and lack of resources the WWTPs have difficulty in fulfilling the purposes of their interventions. It also depends on that the interventions are not evaluated or monitored enough. It shows in the interviews that the WWTP are not working actively with best practice and also that there is no legal requirement for WWTPs to inform households about sewage rules and requirements. WWTPs need to create better structures to their interventions and they also need to evaluate and follow up ALL interventions to make progress in the future. The study also consider that a plan for best practice need to be developed and stricter regulations which also households may be sanctioned if they violate.
