Water Supply and Drainage System Design

Proposals for water supply and drainage systems based on our comprehensive technological capabilities

We prioritize water conservation in our designs, incorporating features such as recycling water and water-saving fixtures.
Beyond our focus on general building water supply and drainage system design, we also propose innovative water supply and drainage systems for plant infrastructures that are resilient in the face of natural disasters by combining existing technologies such as vacuum drainage systems and loop piping.

Vacuum drainage system (onsite infrastructure: BCP measures)

The vacuum drainage system utilizes a vacuum pump to suction wastewater, eliminating the need for a drainage basin and requiring only a shallow pipe depth. This approach reduces the risk of sewage leakage in the event of a disaster, lowers civil engineering costs, and shortens construction time.
This technology is not only suitable for general drainage systems but also can be applied to situations where installing a relay basin is challenging, such as tunnel excavation work.

Pipe looping (onsite water supply infrastructure: BCP measures)

Creating a loop in the piping system ensures that the supply can continue to flow even if a section of the piping is damaged during a disaster. This approach improves the Business Continuity Plan (BCP) for on-site water supply infrastructure and can also be implemented in fire extinguishing piping.

Stormwater control system

Stormwater control aims to minimize flood damage resulting from heavy rainfall and other weather events. This is achieved by either allowing rainwater to soak into the ground (using rainwater infiltration inlets, infiltration trenches, etc.) or temporarily storing rainwater.
Our team has extensive experience in designing a wide range of rainwater runoff control facilities. We can provide accurate calculations, designs, and permit applications for these facilities, helping to mitigate and prevent flood damage and contribute to the overall safety of the urban environment.
