Tool risk reduction measures

100 RISK REDUCTION MEASURES

Soakaways

Soakaways are buried chambers that store surface water and allow it to soak into the ground. They are typically square or circular excavations either filled with rubble or lined with brickwork, pre-cast concrete or polyethylene rings/perforated storage structures surrounded by granular backfill. They can be built in many shapes and can often be accommodated within high-density urban developments, and can also be retro-fitted. (Source/copyright: NRWM-catalogue)
