Abstract

Waste sources, which are not required to be licensed to discharge into water resources projects in 3 surveywd districts accounted for 87.24% on average, including domestic wastewater, livestock, small business units, craft villages, aquaculture, etc. Nearly 100% of these waste sources have not been collected, treated, and there are many shortcomings in management. Content of this paper shows the result of a survey on current status of waste sources management that are not required to be licensed to discharge into the water resources projects in 3 districts of Red River Delta: Khoai Chau (Hung Yen), Binh Luc (Ha Nam), Binh Xuyen (Vinh Phuc) and proposes some solutions to manage waste sources when discharging into water resources projects. To manage the waste sources when discharging into water resources projects, it is necessary to implement synchronous solutions such as: Develop legal documents, assign functions and tasks, improve waste sources management capacity for the water resources projects exploitation units. Raise awareness of community and waste sources owners about discharge of wastewater into water resources projects. Some technical solutions are proposed such as: solution to increase water supply volume for the water resources projects to enhance self-cleaning ability of water sources, wastewater treatment by Nano technology, biological products, plant treatment, building a system of collection and treatment of wastewater along the canal and control the total volume of waste discharged into the water resources projects
