This study was conducted to establishthe appropriate improving plan for a river that flows
into the Yellow Sea, the Moshui River in Qingdao City, China. The river has been damaged by a
rapid industrialization and urbanization for several decades. The river’s environmental
improvement plansconsisted of three phases between 2015 and 2023. The first phase(2015-2017)
is to restore the river’s function by implementing the various action plans,including the
securingwater for the river maintenance flowfrom the treated wastewater, the managing the
pollutants load from the river’s watershed and the contaminated sediments within the river.The
second phase (2018-2020) focus on water quality management of the river by installing the
advanced treatment systems or facilities for wastewater, first-flush, and separate sewer overflow
(SSO). The aim of the third phase (2021-2023) is to rehabilitate the degraded river ecosystem
towardthe aim of ecologically heathy the Moshui River.Our results will provide a helpful
information inplanning to breathe life other urban rivers suffering from the water pollution,
droughts, and habitat loss.
