Did you know that around a quarter of the wastewater that arrives at the plant for treatment does not need to be treated? This is due to the world's seriously deficient sewer networks. One problem here is called infiltration. In other words, the penetration of groundwater and rainwater into the sewer. The additional water causes the volume of wastewater to increase many times over. The thinning of the wastewater reduces the degradation capacity of the sewage treatment plant, and pollutants can increasingly enter the water. One solution to this problem is trenchless sewer rehabilitation. Our trenchless "no-dig" sewer rehabilitation solutions are suitable for the rehabilitation of pipes and sewers with a diameter of 30 to 1800 mm. We do not simply seal these pipes but create a pipe within the existing pipe using a hardened combination of liner material and resin. This finished product forms a friction-locked and structurally sound connection with the existing pipe. Sounds exciting?

Happy Want To Know Wednesday! Have you ever thought about how to assess if your deteriorated wastewater or sewer line is suitable for sliplining rehabilitation? When considering the best rehabilitation method, remember to consider the following: ?? Shape ??Structural integrity ??Condition ??Foreign materials intruding into the host pipe ??Locations of extreme bends, curves, deflections, offset joints or undersized host pipes ??Distance that the liner pipe will have to be pushed #WantToKnowWednesday #allthingspipereline #relinepipe #relineit #trenchless #trenchlesstechnology #piperehab

?? What Damages Sewer Systems and Manholes? Every sewer system and manhole tells a story—and not all are smooth. Over time, several factors contribute to their wear and tear. Here’s what happens underground: ?? ?????????????????? When sewer gases like hydrogen sulfide react with moisture, they create sulfuric acid. This acid eats away at concrete and metal, causing cracks, leaks, and structural weakening. ? ?????????? ?????????????????? Nothing lasts forever. Even the strongest materials used decades ago can’t withstand today’s demands. Time leads to material fatigue, reducing the durability of pipes and manholes. ?? ?????????????????????????? ?????????????? Ground movement, temperature changes, and root intrusions put constant pressure on sewer systems. Over time, these natural forces weaken even the sturdiest structures. ?? ???????????????????????? ?????? ???????????????????????? Water leaks in or out through damaged joints and cracks. This doesn’t just weaken the system—it also strains wastewater treatment facilities and increases costs. ?? ?????????? ?????????????? ???????? Manholes in urban areas bear the weight of increasing traffic loads. Without proper maintenance and materials, this pressure can cause significant damage over time. What’s your biggest challenge in maintaining sewer systems? Let’s connect and find solutions! #Sewer #Manholes #Corrosion #HermesTechnologie #Ergelit #SewerCoatings #Polyurethane #WaterCompany

Hydro excavation, a non-destructive method, involves using high-pressure water and a vacuum system to safely dig or remove soil. Pressurized water breaks up soil, which is then suctioned into a debris tank. This technique is ideal for tasks like working around underground utilities, installing posts, or making repairs without causing damage. It offers precision, reduces environmental impact, and lowers the risk of hitting hidden utilities. #potholing #daylighting #trenching #slottrenching #spoilremoval #NDD Sewer Equipment presents RAMVAC Vacuum Excavators.

?? Backfilling in Stormwater Connections ?? Proper backfilling is important for the longevity and effectiveness of stormwater systems. Here’s why it matters: ?? Material Selection: Using granular materials like gravel ensures excellent compaction and drainage. ?? Layered Backfilling: Placing backfill in uniform layers ensures even distribution and reduces voids. ?? Compaction: Each layer must be compacted properly with mechanical equipment to create a solid foundation. ?? Moisture Control: Correct moisture levels in the backfill material are important for effective compaction and stability. Proper backfilling supports the stormwater pipes, preventing movement and damage, and ensuring long-term system stability. ???????

Sewer network design focuses on optimizing pipe sizes, slopes, and materials to ensure efficient wastewater transport while minimizing environmental impacts. Proper construction and regular maintenance of sewers are essential for preventing blockages, leaks, and system deterioration over time. #SewerDesign #InfrastructureMaintenance #WastewaterManagement #SewerNetworkOptimization #CivilEngineering

Ten Commandments for successful Siphonic Roof Drainage. #7: Velocity of flow in the transition area ? ? In the transition area from a siphonic to a gravity drainage system, the high kinetic energy of the siphonic flow must be converted by reducing the flow velocity to < 2.5 m/s. This measure mitigates the risk of destruction of the downstream components especially in the case of ?o l d e r ?sewer systems. ? Unfortunately, this rule has been omitted from the more recent DIN 1986-100 standard. ?
