Effective Use of Water Resources
Of all the water on Earth, only 2.5% is freshwater, making the efficient use of water resources essential. The Penta-Ocean Construction Group is engaged in initiatives that contribute to the effective use of water resources, such as rainwater storage and utilization, maintenance of water and sewage systems, and reinforcement of reservoir embankments.
Effective Use of Rainwater
The annex of our headquarters building is equipped with a rainwater storage tank on the premises to effectively utilize rainwater, which is used for sprinkling on roofs, outdoor unit of air conditioners, and paved surfaces. In addition, the building is also designed to reduce CO2 emissions through the use of various energy-saving technologies.
Contributing to the Construction of Water Supply and Sewage Facilities
We contribute to the construction of water supply and wastewater treatment facilities that form the foundation of daily life and play a vital role in improving public health and enhancing the quality of public water environments.
We have also developed sulfuric acid-resistant concrete which features a 100-year lifespan. Resistant to the hydrogen sulfide gas generated in sewer tunnels, it is being used in sewer tunnel construction.

Reinforcement of Reservoir Embankments Using the Water-Absorbing Mud Stabilization Material "Watoru"
To prevent the collapse of reservoirs due to heavy rain or typhoons and to enable their continued use as agricultural water facilities, we are developing reinforcement technology for reservoirs using the water-absorbing mud stabilization material "Watoru *".
