Gravitational waterways are being built one after another in the DPRK.
The Kaechon-Lake Thaesong Waterway, the first large-scale gravity-fed irrigation system in the country, was brought to completion in 2002, to be followed by the Paengma-Cholsan Waterway in 2005, and then the Miru Plain Waterway.
In 2016, the first-stage project of South Hwanghae Province Waterway passing through hundreds-of-kilometre-long mountains and fields in the western area of the country was completed.
Along with large-scale waterways, tens of medium- and small-sized waterways have also been built in succession.
The total length of those gravity-fed waterways built up to 2019 reaches over 11 600 km.
The waterways are paying off.
A new gravity-fed irrigation system has been set up in the country to open a prospect for radically boosting agricultural production.
Over 10 billion tons of water flew through the Kaechon-Lake Thaesong Waterway to 100 000 hectares of crop land in over 10 cities, counties and districts in Pyongyang Municipality and South Phyongan Province located in the western part of the country.
It is equivalent to the amount of water that ten large-sized pumps with a capacity of 2 tons per second have to draw without stopping for about 20 years.
Agricultural workers say that, thanks to the waterways, they can ensure stable harvest, free from worries about unfavourable weather conditions.
The waterways are bringing great benefits to the economic development of the country and the improvement of the people’s living standards.
Thousands of water pumps, electric motors and transformers have been removed from many pumping stations, which made it possible to economize on billions of kWh of electric power. This brings much more profits to the country than building a power station with a generating capacity of hundreds of thousands of kW.
Several reservoirs and small-sized power plants have been built along the waterways.
The waterways increased tens of thousands of kW more generating capacity at the existing medium- and small-sized hydroelectric power stations.
They made it possible to provide drinking water and industrial water sufficiently in the areas of waterways.
They transformed the appearance of the land of the country.
At present, the DPRK is vigorously promoting the projects to build more gravitational waterways, including the second-stage waterway project of South Hwanghae Province and the Chongchon River-Phyongnam irrigation waterway.
