Goyang City to Expand Tap Water Supply Network by 2040...More Reservoirs and Double-Tracking of Pipelines
Approval of Waterworks Plan by the Ministry of Climate, Energy, and Environment
System to Supply Up to 471,000 Cubic Meters Per Day
Expansion of Jugyo Reservoir, Construction of New Pungsan Reservoir
48.9 Billion Won Invested in Pipeline Upgrades and Other Improvements
In response to the rising water demand driven by urban development, Goyang Special City in Gyeonggi Province is strengthening its tap water supply system by expanding its reservoirs and double-tracking the water transmission pipelines.
On the 27th, Goyang City (Mayor Minkyungseon Min) announced that it received approval from the Ministry of Climate, Energy, and Environment in July for the revised Goyang City Waterworks Maintenance Plan, which is scheduled to be publicly announced within this month.
The main objective of the new plan is to build a system capable of supplying up to 471,000 cubic meters of water per day by 2040. The city's estimated maximum daily demand for 2040 is 464,277 cubic meters, which is 6,723 cubic meters less than the supply capacity.
To reflect water demand for major development projects such as the Changneung Public Housing District, Pungdong 2 District, and Seongsa Innovation District, the city plans to expand two reservoirs and construct three new ones. In addition, completed facilities will undergo regular in-depth safety inspections and technical evaluations of the water supply network, in order to strengthen both the safety and management systems for the water infrastructure.
A ‘reservoir’ is a storage facility where water, drawn from water sources and then purified at water treatment plants, is kept before being distributed to households. Currently, Goyang City operates 18 reservoirs of various sizes. Larger reservoirs can hold more water, which makes it possible to cope flexibly with fluctuations in water demand and ensure a stable supply of tap water.
In Jugyo-dong, where a redevelopment maintenance project in the Wondang District is expected to increase water demand, the city is expanding the existing Jugyo Reservoir from 2,800 cubic meters by an additional 4,400 cubic meters, resulting in a total capacity of 7,200 cubic meters. Construction began in June, with the aim of completion in December 2028.
Additionally, a new 10,000-cubic-meter Pungsan Reservoir will be constructed in the Pungdong and Siksadong area. This project, which is intended to reduce the burden on the existing Gobong Reservoir, began design work in July and is scheduled for completion in 2030.
Goyang City is also advancing a project to stabilize its water transmission pipelines. The single 3.08-kilometer water pipeline serving Seongsadong, Haengshindong, Todangdong, and Hwajeongdong will be double-tracked, and 6.11 kilometers of pipelines that have been in use for over 30 years will be upgraded. The goal is to minimize water supply disruptions by ensuring that water can be supplied through the alternate pipeline in the event one is damaged. The Jugyo Reservoir expansion and pipeline stabilization projects are expected to require a total investment of 48.9 billion won.

Currently, tap water treated at the Goyang Water Treatment Plant is delivered through the Daeja Regulating Reservoir to 13 different reservoirs. However, since each reservoir is supplied through a single pipeline, emergencies such as pipeline damage make it difficult to reroute water supplies, which is a significant challenge.
Minkyungseon Min, Mayor of Goyang Special City, stated, "Providing clean and safe tap water is a vital administrative service that is directly connected to citizens' daily lives. By executing the newly revised waterworks maintenance plan, we will establish a stable water supply system that can withstand emergencies without disruption."
