Nu Pipes for Netcare Milpark Hospital

Site:
Netcare Milpark Hospital

Situation:
Milpark Hospital was experiencing constant blockages on one of the hospitals main sewer lines. Nu Flow was called to unblock the sewer line and camera inspect the pipe to find the reason for the constant blockages. The camera inspection revealed that the pipe was cracked in sections and had shifted joints. The section in question consisted of 20 meters of 110mm earthenware sewer pipe which ties into a 30 meter section of 160mm earthenware sewer pipe. Both sections of pipe had defects.

The sections in question run under the doctors parking lot, under a corridor and passage way, under doctors offices including a plastic surgeons nicely furnished consulting rooms, and under two hospital wards.

This made a pipe replacement something the hospital definitely wanted to avoid as far as possible as it would be difficult and disruptive. The doctors would need to be temporarily moved and the two wards under which the pipe runs would be out of use while contractors break open the hospital floor and excavate 2 to 3 meter deep to replace the pipe.

This was not an option. The hospital turned to Nu Flow for a faster, less disruptive solution.

Solution:
Nu Flow relined the pipe working at night from 9pm to 7 am every night until the job was completed as the sewer lines were less active during these hours. The technicians had to run a bypass line and over pump while working on the section of pipe as the hospital obviously can’t stop using bathrooms.

Nu Flow technicians relined the 20 meter section of 110mm earthenware pipe and the 30 meter section of 160mm earthenware pipe using Nu Flow structural liners saturated in Nu Flow’s 100% solids epoxy resin thereby creating a “Nu Pipe” within the old cracked and broken host pipe. All work was done working from manholes and inspection eyes thereby causing minimal disruption to the hospital.

How it works:
The pipes are first cleaned using high pressure jetting. Once the pipes are clean, an epoxy saturated liner is pulled into the pipe. Within the liner is an inflatable bladder. When the liner is in the correct position the bladder is inflated and left inflated until the epoxy has cured. Once the epoxy has hardened the bladder is removed leaving behind a “nu pipe” within the host pipe.
