Brigades of the waterway construction division are speeding up the project.

The Pyongyang City Brigade has over-fulfilled its daily quota by operating water-pumping machines at full capacity to provide conditions favorable for concrete tamping.

The Jagang Provincial Brigade is regularly repairing tunneling equipment in battalions to timely overcome the factors that may hinder the achievement of its daily quota.

Achievements are also reported from the South Hamgyong Provincial Brigade, the South Phyongan Provincial Brigade and the North Hwanghae Provincial Brigade.
