What is commercial sewer unblocking and why is it important?


What is commercial sewer unblocking and why is it important?

Commercial sewer unblocking involves the professional removal of blockages in the sewers of businesses, offices, restaurants, factories, schools, and institutions. While a blocked drain at home can cause considerable annoyance, a blocked commercial sewer can literally shut down business operations. Think of odor nuisance, toilet or shower outages, subsidence around pipes, or damage to installations. Commercial sewers often handle larger volumes of wastewater and are therefore more likely to encounter complex blockages, grease and soap residue, or even construction debris. The consequences of a blocked commercial sewer extend beyond mere inconvenience: they entail business risks, reputational damage, and high costs.

At Ontstoppen.nl We know that a well-functioning sewer system is vital for optimal business continuity. By responding promptly to malfunctions or scheduling regular maintenance, you keep wastewater and rainwater flowing smoothly and prevent major problems. Professional, fast, with high-quality equipment, and always transparent about costs and warranties.

How does the process of unblocking a commercial sewer work?

For commercial sewer unblocking, we employ a structured, methodical approach that aligns with the technical complexity of commercial buildings. We utilize advanced equipment, including high-pressure cleaners, city cleaning machines, drain cleaning springs, and camera inspections in accordance with the applicable protocols of the VSR (Cleaning Research Association) and NEN-EN 13508-2. This means we don't just treat the symptoms, but always address the underlying cause: from grease buildup in a catering kitchen to root growth in the outdoor sewer system.

  1. Inspection and diagnosis: We start with a thorough inspection using cameras, smoke detection, or dyes to locate the exact problem area.
  2. Mechanical unblocking: In case of waste accumulation or blockages, we use spring machines and effective milling or flushing techniques.
  3. High-pressure cleaning: We clean the pipe system to remove all residue and deposits, which restores flow.
  4. Aftercare and advice: After clearing the blockage, we check the flow and provide you with tips for smart management of your company sewer system.

Causes of blockages in the industrial sewer and prevention

Clogs are mainly caused by a combination of improper use, overloading, and lack of maintenance. Some recurring culprits:

  • Fat and oil waste: Builds up in pipes in canteens and catering establishments, leading to persistent blockages.
  • Rinsing wipes and waste: In public toilets and sanitary facilities of companies, unsuitable material is often flushed away.
  • Construction and grinding waste: During renovations and conversions, grit remains in the sewer, causing blockages.
  • Root growth and subsidence: Trees and shrubs surrounding the property can push roots into the sewer system, causing cracks and leaks.

Good preventative sewer management is key to preventing malfunctions. Consider periodic inspections, timely cleaning, and the installation of grates, grease separators, and sand traps. Our technicians are happy to provide comprehensive advice on smart sewer management.
