Echo Square Services recently completed the drainage jetting and mechanical cleaning of a concrete rainwater tank and its associated blocked pipework in the basement of a multi-story building in Kensington.
The building is currently an active building site due to the entire property undergoing a full refurbishment converting it from a residential dwelling to a high-end hotel.
Therefore, safety was of paramount importance while working in close proximity of other contractors.
Full confined spaces entry was required into the water tank ensuring our pipe jetting works could be carried out safely.
Why was drainage jetting required?
The existing concrete water tank was installed over 40 years ago and required extensive cleaning and jetting prior to it being repurposed.
The existing blocked pipework lines had numerous concrete deposits which required removal utilising our mechanical cleaning methods.
Concrete had also solidified on the base of the tank which required mechanical removal.
Drainage jetting and water tank cleaning process
Our operatives initially drained the water tank to allow safe entry into the tank.
Pipe cleaning was then carried out utilising our water jetting method, any solidified concrete which couldn’t be removed using high pressure water jets was removed mechanically utilising specialist concrete removal tools.
Once our operatives had unblocked all pipe work, we then completed the water tank clean, which involved removing all loose concrete and excess solidified concrete from the water tanks base.
Pipe CCTV camera survey
To highlight the progress of our works we completed a pipe camera survey of all pipework leading into the concrete tank.
All findings were compiled into a full completion report which included further recommendations for the customer to consider.
These recommendations included carrying out the internal pipe relining to help future proof the existing pipework.
We also recommended carrying out a full water tank reline of the existing concrete water tank to provide long term protection for when it’s eventually placed back into use
