Key Aspects of Land Drainage Design
Effective and efficient land drainage design relies on several key elements that work in perfect sync to manage excess water on the site. Our land drainage design specialists carefully assess every detail on the site to incorporate its findings into the final design. The key aspects we evaluate are:
Surface Water
A detailed surface evaluation to determine the natural flow of water across the site.
Soil Condition
Expert soil testing to calculate how quickly the water gets absorbed into the ground.
Pipe Sizing
Pipe sizing and gradient calculation to ensure smooth, efficient water drainage flow
Outfall Connections
Install water discharge pipes to collect the water and move it away from the building.
