Top Class in Japan! Completion of Steel Drinking Water Tank

-Order for Related Work from Okayama Prefectural Water System for Wide Area Supply Authority -

 

Kawasaki Steelís Pipeline Engineering Division recently completed the construction of Japanís second largest steel distributing reservoir for drinking water, which was ordered by the Okayama Prefectural Water System for Wide Area Supply Authority.

The distributing reservoir is a circular structure approximately 12 meters in height and 54 meters in diameter, and has an effective capacity of 23,000 cubic meters. Roughly 530 tons of steel were used in the construction. This facility will supply daily drinking water to one city, seven towns, and two water works corporations in southern Okayama Prefecture, including the city of Okayama, and will also serve as a regional water source in case of earthquakes or other emergencies.

In this project, various unique methods were adopted. These included the use of two side horizontal automatic welders in welding the side plates of the tank, and the application of an epoxy resin lining to the under side of the roof and other parts by a special method in order to prevent corrosion by chlorine gas, with the aim of creating a maintenance free facility.
