Sewer will be worn out by age. Sewer transports all sewage to treatment facilities while manhole gives access to perform maintenance work of underground plumbing and sewage systems. Issues such as overflowing and blockage of pipe cannot be resolved without these manholes. Manholes serve as an entry for maintenance of defective or problematic lines, plumbing and electrical systems. Sometimes due to resurface of road or buried by soil, location of manholes cannot be identified or considered as missing.
Therefore, particular crew for detecting the buried/missing manhole is required to carry out manhole detection. With the help of manhole detecting equipment and well trained expertise in this field, any unidentified location of manhole will be found. Buried manhole will then be raised to preferred level compliance to requirements for future maintenance purposes.
