Range of concrete based, customized On Site Detention (OSD)
sytems for stormwater and sewerage applications.
OSD systems are customised for each aplication from the standard
Rocla range: steel reinforced high strength precast concrete pipes,
box culverts and pits (including grates, step irons, access
chambers and inlet/outlet pipe penetrations).
Precast, reinforced components reduce construction times,
increases durability and reduces maintenance. The OSD tank can be
backfilled the same day it is installed therefore increasing site
The tanks can be designed and manufactured for full highway
loadings resulting in a fully trafficable OSD tank.
Additional storage volumes can be achieved when combining the
Rocla OSD tank with a Rocla Hydro-Brake flow regulator which can be
pre-fitted into the detention tank.
