When sewers collapse or need repairs the flows must be bypassed leaving the damaged pipework clear to be replaced or relined. We have done many such jobs in and around Melbourne for many years. Of particular importance to our clients is that the equipment is absolutely reliable and that there is no spillage whatsoever. We have a large amount of equipment to do such jobs and we have purpose built silenced containerised pumpsets for this specialised work. We have a diesel system that will pump flows to 160 litres per second and electric pumps to pump up to 440 litres per second.

The diesel pumpset has 2 diesel motors controlled by level sensors which turn the pumps on and off  and control the speed to maintain a constant level in the sewer. This is important to minimise the possibility of a surcharge in the pipes, which could result in further damage. The pumpset is also equipped with SMS messaging to alert operators and supervisors to any engine failures or high sewer levels. The pumps can be remotely stopped and started by SMS messaging. Flow rates are recorded using Magnetic flowmeters.

Sound levels are less than 75dB(A) at 1 metre and so this equipment can be used in suburban areas with minimum disruption to residents. Having all the equipment within a container allows for rapid deployment and good security.

For larger flows we have a containerised pumpset with 2 large 250mm NB self priming pumps driven electrically.

These generally will be used as duty pump and back up pump.  Control is via dual variable speed drives housed in a separate container complete with computer controlled start/stop and speed variation to maintain accurate levels. This system also includes SMS alerting and remote start and stop.

For situations where a rapid response is required we have silenced vacuum assist pumps, both trailer and skid mounted. These pumps can be deployed very quickly in an emergency.
