In days gone by, the maintenance and repair of numerous sewerage systems had remained a somewhat intricate, if not messy and dangerous business, so much so that many public service administrators and business and property owners had avoided it as though it were the plague. This unfortunate avoidance has, of course, had its pitfalls. Damaged and heavily polluted sewerage systems became even more of a challenge for qualified and specialist plumbing technicians to work on.
It could even be that any number of specialist plumbers, in order to remain viable and sustainable as a business, have turned their heads and expertise to other areas, thus allowing further neglect of the underground urban infrastructures. Fortunately, the tide has been changing in a positive direction, slowly but surely over a number of years. Some years ago, a team of engineers developed a system known as trenchless sewer repair. The systematized term is self-explanatory. No longer do dedicated engineers need to venture below the ground to carry out the dangerous and dirty business of urgent sewerage repairs.
Digital cameras are lowered below the ground and manned above its surface. Technicians are able to give an accurate inspection of the below the ground territory without ever needing to get their hands and ankles muddied or placing themselves at risk. Once the damage of the sewerage piping has been located, engineers are able to process a skeleton of the original pipe. Utilizing devices lowered and managed above the surface, an extremely thick resin coats the damaged area or cracks. Call it a case of covering the cracks if you will.
But the work is effective and it is sustainable. It is a boon to urban cities’ infrastructures and its every day traffic, not to mention the savings of not having to hire and pay for heavy digging equipment.
