A substantial range of one piece vessels, from 1,000L to 275,000L, are offered.
These tanks can be supplied with baffles, access ladders, multiple access shafts etc. if required.
Alternatively, the FCD can be fitted into a separate chamber, or supplied loose to be installed into an existing outlet manhole chamber by others.
The attenuation tank can be manufactured with an integral Flow Control Device (FCD) sized to the specific outflow requirement.
Where levels prevent the use of a gravity fed (FCD) the Attenuation tank can be supplied with a pumped discharge, again sized to the permitted outflow criteria.
