Will your new stormwater system deliver reliable long-term performance?
Soakage pits, raingardens, retarding basins, and other stormwater management systems all depend on one critical design parameter... the soil’s hydraulic conductivity.
Hydraulic conductivity determines how quickly water can move through the soil. It is a fundamental input for designing stormwater systems that function effectively, meet regulatory requirements, and provide confidence in long-term operation by capturing stormwater and allowing it to infiltrate into the ground - sustainably in an urban environment.
SITE Geotechnical provides on-site investigation, including soil infiltration testing to measure hydraulic conductivity, the key parameter used by designers to ensure effective sizing, performance, and long-term function of infiltration-based stormwater systems.
In general, sites with sandy soils provide greater infiltration rates, resulting in a smaller footprint and a more efficient system. Other soil types can also be used, and the field testing provides the data needed to understand the individual site conditions and tailor the design appropriately.
✅ Get the testing done
✅ Determine the parameters
✅ Design with confidence
With reliable site-specific data, your stormwater system can be designed to perform as intended, giving designers, councils and other regulatory authorities the required information they need.
