A non-standard pipe size was no worries for Smart Lock when one of its valued international clients came with a challenge of rehabilitating an existing sewer asset for the Hong Kong Drainage Services Department.
When Smart Lock was called up by a client to assist the Hong Kong Drainage Services Department, the rehabilitation solutions contractor simply asked; “What size do you need?”
Like most rehabilitation projects it starts with aging and/or damaged assets, and each with their own challenges. These can vary from access, flow, time, retention, size, or the environment they are set in. And this project wasn’t exempt and provided its own challenges, especially the diameter of the asset.
With DN440mm and DN480mm required, Smart Lock was able to collaborate with both the client and asset owner technical leads to establish the exact internal diameters of the assets in question, then manufacture the custom size and deliver within two weeks from order.
In addition to the asset diameter challenge, time and flows were also an obstacle, with limited network retention. Time was of the essence, which led to the Smart Lock flow through air packer being the perfect piece of equipment for the job.
As a result, the Smart Lock packer allowed continual flow during instillation on the live asset, avoiding any inconvenience to the end user and additional cost for flow control.
Smart Lock provide specific rigid packers ranging from DN100 – DN900 along with other sewer rehabilitation accessories.
Excellent execution
With full endorsement from the Hong Kong Drainage Services Department, Smart Lock’s client was able to provide a solid rehabilitation methodology.
Not only did Smart Lock provide efficient project execution across multiple street pipe crossings, but it was also done with minimal impact on stakeholders, end-users, environment, and the asset.
Since its inception in September 1989, the Hong Kong Drainage Services Department has been striving to upgrade sewage treatment and flood protection levels in Hong Kong.
Over the years, it has completed projects such as the regulation of Shenzhen River Stage IV, the enhancement works for Kwun Tong Sewage Pumping Station, the Inter-reservoirs transfer scheme, and the revitalisation works of the Jordan Valley Nullah.
Smart Lock technology provides asset owners, asset managers and contractors the gold standard in point repairs with time and costs savings, a structural repair and full seal.
