Large Sewage Clean Up
NLR responded to a weekend call to a newly built hotel in the CBD which had a build-up in one of its pipes, resulting in sewage back up in the floor drains of 6 units on the same floor. Technicians responded quickly and were able to extract the sewage, remove affected materials and dry-down the structure.

#Damage Caused
There were several rooms that were affected as a result of the blockage and subsequent drain back up on the level. The following building elements were affected by the sewage:
Wool carpets in units and hallway
Tiled bathrooms and kitchens
Plasterboard ceilings of lower affected rooms
Concrete subfloor
#Portable Extraction
Due to the biohazardous nature of sewage, it is imperative to both remove anything that is biohazardous by physical removal and sanitize the areas. In this case, because of the large volume and liquid nature of the sewage, using portable extractors were the most effective means to physically remove the sewage. These portable extractors provide powerful suction that safely sucks and store the substances within the machine, to be disposed of in safe ways. The portable nature of the machines gives great convenience and effectiveness as means to extracting water and/or sewage.
In heavily affected areas, the wool carpets were removed and disposed of. Once sewage was removed, including heavily affected carpets, tiles and concrete subfloors were treated with anti-microbial treatments, to sanitize the area. lower levels were checked, finding a few affected areas. 19 air movers and 7 dehumidifiers were placed down, to dry-down the structure. Coliform/E.coli testing was done after 4 days, to test the presence of sewage, and came back absent. The drying equipment was removed after 5 days.
