Since its foundation in September 1986, the Korean Society of Water and Wastewater has made a significant contribution to the water sector in Korea over the past 30 years. The 30th anniversary commemorative committee reviewed the establishment goal of the society and its development strategy for organization and present the "Future Vision of Korean Society of Water and Wastewater" for the next 30 years. The future vision of the society is defined as "Aiming for the healthy life and preservation of the environment through the development of water and wastewater technology and experience". Promotion strategies for implementing the future vision are as follows: 1. Leading water and wastewater technology, 2. Develop water and wastewater policy, 3. Strengthen water and wastewater capacity, 4. Reinforce institutional governance. The driving target to be achieved through the implementation strategy is "To lead the global standards of water and wastewater." We also presented national issue, policy issue, and technical issues in the water sector. Climate change, unified Korea, water safety, and national welfare were selected as national issues related to water and wastewater. This approach was taken from the perspective of policy consumers such as citizens, civil society, experts, and local government/industry. By presenting policy issues and technical issues that address national issues, authors have proposed a future policy direction for the Korean Water and Wastewater Society to make critical contributions to national development.

This study examined the wastewater at a livestock farm, and found that the dairy wastewater from the milking parlor had a lower concentration than the piggery wastewater, and that it was produced at a rate under 1.3 ㎥/day in a single farmhouse. The amount of dairy wastewater was determined based on the performance of the milking machine, the maintenance method of the milking parlor, and the amount of milk production allocated for each farmhouse, not by the area. The results confirmed that both dairy wastewater treatment processes, specifically those using Hanged Bio-Compactor (HBC) and Sequencing Batch Reactor (SBR), can fully satisfy the water quality standards of discharge. The dairy wastewater has a lower amount and concentration than piggery wastewater, meaning it is less valuable as liquid fertilizer, but it can be easily degraded using the conventional activated sludge process in a public sewage treatment plant. Therefore, discharging the dairy wastewater after individual treatment was expected to be a more reasonable method than consigning it to the centralized wastewater treatment plant. The effluent after the SBR process showed a lower degree of color than the HBC effluent, which was attributed to biological adsorption. In the case of the milking parlor in the livestock farm, the concentrations of the effluents obtained after HBC and SBR treatments both satisfied water quality standards for the discharge of public livestock wastewater treatment plants at 99% confidence intervals, and the concentrations of total nitrogen and phosphorous in untreated wastewater were even lower than the water quality standards of discharge. Therefore, we need to discuss strengthening the water quality standards to reduce environmental pollution.
