Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage:
- The hydroelectric turbines are lubricated by lubrication oils.
- The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils.
- Vehicles including fork lifts, trucks, etc., can spill oils and fuels.
Any accidental spillage of oil or grease or intentional wash down water containing minor amounts of oils, greases, and detergents must be collected and treated before discharge to the river. These fluids along with any water leaks are collected in sumps in the dam and are regularly pumped out. In many cases, the volume of water is substantial.

Nilex’s engineered erosion control and sediment control products reduce the damaging effects of rainfall, wind and wave action on soil structures while replacing or reducing the dependency on scarce natural resources.
Geosynthetic erosion control products are designed to reduce damaging effects of rainfall, run-off, and wave and wind action on soil structures by redirecting water flow or acting as a barrier between the soil surface and water.
Nilex Erosion Control systems include: Erosion Control Blankets (ECBs); Turf Reinforcement Mats(TRMs); Gabion systems; Concrete Revetment and Mattresses; and Cellular Confinementsystems.
Properly implemented sediment control practices can result in minimal soil loss, little damage to
off-site receiving channels, enhanced project aesthetics and fewer complaints from regulators and the public.
Nilex Sediment Control systems include: GeoRidge Bio; Silt Fence; Turbidity Curtains;SedimentSTOP and Wattles; and Water Inflated Dams.
