We’ve worked closely with the City of Ottawa on a number of recent projects, such as the West End pumping stations, Alta Vista culvert replacement, and the John Asselford Weir removal.
Sediment ponds are used to store stormwater runoff, which can carry pollutants into streams and rivers. Sediment on the bottom of a pond may accumulate as a result of nearby construction, vandalism, or accidental damage.
Sediment buildup is also caused by heavy rainfall and snowmelt, which can cause an excess amount of sediment to flow into a nearby creek over time. Sedimentation can also occur when a pond becomes clogged with leaves, twigs, and other debris that has accumulated on the surface.
Passive ponds are less prone to sediment buildup than active ponds because they don’t have moving parts. Passive ponds may be constructed from plastic liners or concrete slabs. Active ponds use pumps and other mechanisms to move water through their systems.
Additional maintenance requirements for active ponds include regular cleaning of the system and maintenance of all exposed surfaces.
