01
Diagnose the water column
Bathymetric surveys, CTD thermocline profiling, dissolved-oxygen profiles and sediment nitrogen/phosphorus release assessment.
PILLAR 01 / AQUATIC ECOSYSTEMS
Targeted hypolimnetic oxygenation and multi-barrier restoration for drinking water reservoirs.
THE CHALLENGE
Seasonal thermal stratification can isolate deep water, driving anoxia and the internal release of iron, manganese, ammonium and reactive phosphorus.
THE APPROACH
We combine three-dimensional reservoir diagnosis with targeted deep-water oxygenation, inflow wetlands, littoral planting and calibrated food-web management. The oxygenation system is designed to preserve the natural thermocline.

TECHNICAL SCOPE
01
Bathymetric surveys, CTD thermocline profiling, dissolved-oxygen profiles and sediment nitrogen/phosphorus release assessment.
02
Deliver oxygen-rich water to the target depth without resuspending sediment or deliberately mixing the entire reservoir.
03
Combine inflow subsurface wetlands, bay restoration, macrophyte belts and food-web control around site-specific risks.
BROCHURE REFERENCE / TECHNICAL CONTEXT
Brochure system specification: 15 m deployment depth, 150 m³/h and outlet DO ≥30 mg/L.
The DO value describes oxygenated system output, not a reservoir-wide dissolved-oxygen target. Specifications require site-specific design.
