There are thousands of maintenance holes (manholes) in suburbs and towns, they are often overlooked. When you do notice a manhole, its usually for the wrong reason \u2013 like when it\u2019s overflowing. Even worse, if it\u2019s overflowing and raw sewage is running into your back yard.<\/p>\n\n\n\n
Unfortunately, this was the case for some of the residents in a quiet South East Queensland suburb.<\/p>\n\n\n\n
The overflowing manhole was reported to the local water authority, who organised to clear the blockage. The manhole was behind the home, situated on the side of a steep hill which had between a 40 and 45 degree pitch.<\/p>\n\n\n\n
Working on an incline like this made it extremely challenging, so when the water authority discovered the issue was a damaged junction (branch) and a cracked manhole due to tree root activity, they reached out to Nuflow Gold Coast.<\/p>\n\n\n\n
It\u2019s not unusual in a situation like this for a water authority to completely dig up the faulty manhole and pipes and renew everything \u2013 especially when the manhole discharge is flowing into residential properties with the potential to cause health and environmental issues. The downside of this approach would mean lots of heavy equipment and disruption to the local residents.<\/p>\n\n\n\n
Instead, the water authority decided to Nuflow Gold Coast to rehabilitate the entire sewage system with pipe relining, and to delete the manhole. Our Nuflow pipe relining experts were able to use a no-dig solution to repair the damaged and broken pipes and manholes, without the need for excavating. This meant less disruption to the local residents from noise and pollution \u2013 in fact, they probably never even realised the job was being done.<\/p>\n\n\n\n
The process involved relining the entire junction with a one-piece relining system. Now, the 45 degree junction is one seamless structure, with no joints that could catch debris and cause future blockages.<\/p>\n\n\n\n
Once the manhole was repaired, it was filled with sand and sealed with concrete. Nuflow also installed signs stating the \u201cmanhole is not in use\u201d and affixed them in two locations for future maintenance teams to easily see.<\/p>\n\n\n\n
