  • K-water is committed to creating smart water cycle cities and new values for water by utilizing ground water discharge. The following are some of the key words associated with K-water’s efforts to create a healthy water cycle city.
Water Cycle

The “water cycle” refers to a continuous flow of water in which precipitation first becomes surface and ground water, and then flows into or is stored in rivers, lakes, swamps, and sea, before evaporating and becoming rain again. K-water is working to create smart water cycle cities in line with its integrated water management policy, and is also implementing various projects to create K-water-style future water cycle cities and to work out the issues related to deterioration of the water supply in the face of climate change.

Improved urban water cycle

The water cycle system, which constantly repeats itself, is heavily affected by artificial structures created in the process of urbanization. As such, the water cycle can be divided into two categories: the natural water cycle and the artificial water cycle. The Ministry of Environment and K-water are currently in the process of developing a model for management of the urban water cycle, in which green and grey infrastructures are connected.

Busan Eco-Delta Smart City

Busan Eco-Delta City is a smart city that is being created as a national pilot project on a site covering 11.77㎢(3.6 million pyeong).
The project will feature the application of real-time data-based smart water management including flood response, water supply and water quality control, a water cycle platform for water disaster prevention, and water cycle technologies that use rainwater, water heat, geothermal heat and ICT, all of which are innovative technologies requiring citizens’ participation.

Use of ground water discharge

The amount of groundwater discharge is increasing continuously as a result of urbanization and the construction of large-scale underground facilities. In order to make better use of groundwater discharge, K-water has established facilities in the subway stations run by the Daejeon Transportation Corporation and the Yongin Indoor Gymnasium to enable the use of groundwater discharge for such purposes as air-conditioning in buildings and gardening in public parks as part of a pilot project. The project will also be implemented in Busan Metropolitan City and in Siheung City in Gyeonggido Province to enable the use of groundwater discharge for air-conditioning in subway stations and gardening at public parks.
