CASE STUDY EXAMPLE
Our client manages a block of 24 units over 6 levels. They had been suffering from continual water leaks originating from the old cast iron and galvanised stack work carrying bathroom grey water, sewer, and kitchen waste from each level to the sewer system underground. The original plumbing within the building had been configured in such a way that each of the 3 wastes were contained within their individual stacks, to meet the old plumbing code of practice. This group of 3 stacks was repeated in each of the four comers of the building. Four groups of three stacks obviously creates the potential for a large number of leaks.
Two of these stacks. bathroom grey water (shower, bath, basins) and toilet waste were contained within one cavity, and the kitchen waste was contained in another cavity on the opposite side of the unit.
In meeting with the new code of practice Trenchless put a proposal to our client to reline the 100rnm cast iron toilet waste stack from the rooftop to the main line, underground, reinstate the toilet junctions from the roof top with the use of our robotic junction cutter, and then by accessing the roof cavity within the bathroom of each unit, redivert all the galvanised bathroom waste water pipe work into the new relined 100mm stack. This would eliminate one entire stack from the building, minimising any potential for future leaks. This would leave the building with a brand new relined pipe stronger than a new PVC pipe and all this work was carried out with minimal disturbance to residents with only a small access panel being cut in each unit leaving only small restoration costs.
The proposal also contained relining the existing 80mm galvanised iron kitchen waste stack again from the rooftop to the sub floor drainage. The reinstatement of each units kitchen drainage would then involve accessing each unit, removing the kitchen trap and with the use of a flexible hole saw reinstate the kitchen drainage.
In total, our proposal would be completed within one week, would eliminate one entire stack, cause minimal disturbance to residents and provide the residents with brand new stack work.
The alternative, was to access each bathroom, of which the majority were fully renovated, demolish the existing stack work to gain access to the pipe work, replace the pipe work and fittings, and reinstate the bathrooms. The time line for a project of this size was weeks with the restoration costs being an unknown depending on availability of trades and not to mention the availability of tiles etc.
The project was undertaken to renew the first group of stacks, and was completed within time and on budget The entire project was great success. and a program is now in place to continue with the remaining stacks over a period of time.
