Drain and Tank Cleaning
Drains interceptors and tanks often need cleaning to remove debris or waste, it is also highly advised to clean drains prior to CCTV survey to allow a comprehensive report by allowing full visibility.
Redwood Environmental operate Jet Vac units from 1000 gallons to 4000 gallons with high power jetting available to clean from low to high volume drains.
What Happens if I need repairs?
Often damage to drainage systems are caused by subsidence, poor installation or root ingress Redwood Environmental Services can provide re-active repairs or planned maintenance to drains and treatment plants whether it be a no dig solution or a full dig up repair.
Drainage Installation
In addition to our repair and maintenance drain service, our engineers have the skills and experience to install drainage systems. When you choose Redwood environmental services for your drainage installation, you can rest assured that the work will be completed to the highest standard.
High Pressure Water Jetting
High pressure water jetting is a commonly used process for cleaning and maintaining sewer pipes. The process involves using a high-pressure water jet to blast away blockages and debris that have accumulated inside the pipes. All our technicians are fully trained with many years’ experience.
Here is a general overview of the process of high-pressure water jetting sewer pipes:
- Inspection: Before starting the high-pressure water jetting process, the sewer pipes are inspected to determine the location and extent of the blockage. This may involve using cameras, sonar equipment, or other techniques to get a clear view of the pipes and the blockage.
- Set up: The high-pressure water jetting equipment is set up and tested to ensure that it is working correctly. This includes connecting the water supply, setting the pressure and flow rate, and checking the safety systems.
- Cleaning: A specialised nozzle is attached to the end of the high-pressure water jet, and the water is directed into the sewer pipe. The pressure of the water is adjusted to suit the specific requirements of the task, and the nozzle is moved through the pipe to blast away the blockage.
- Monitoring: The process of high-pressure water jetting is closely monitored by the operator to ensure that it is safe and effective. The operator will also check the equipment regularly to make sure that it is working correctly and make any necessary adjustments.
- Clean-up: After the high-pressure water jetting process is complete, any debris that has been dislodged from the pipes is removed and disposed of. The equipment is also cleaned and prepared for the next job.
Overall, high pressure water jetting is an effective and efficient way of cleaning sewer pipes, and it is often used in combination with other techniques such as rodding and sewer excavation to ensure that the pipes are fully cleared and functioning properly.
Patch / Continuous Lining
Patch lining and continuous lining are two methods of repairing and reinforcing underground pipes, such as water and sewer pipelines.
- Patch Lining: Patch lining is a technique used to repair isolated defects or damages in a pipeline, such as cracks, holes, or corrosion. The process involves the insertion of a flexible, resin-impregnated liner into the damaged section of the pipe. The liner is then inflated to shape it against the inner wall of the pipe. The resin is then cured to form a hard, durable patch that reinforces the damaged area and prevents further leaks or collapses.
- Continuous Lining: Continuous lining, on the other hand, involves the installation of a continuous liner over the entire length of the pipeline. This technique is typically used when the pipeline is severely damaged or has reached the end of its useful life. The liner is installed by pulling it into the pipeline and then inflating it to shape it against the inner wall of the pipe. The resin is then cured to form a continuous and seamless lining that reinforces the entire pipeline.
Both patch lining and continuous lining are trenchless repair techniques, which means that they can be performed without excavation and with minimal disruption to the surface. They are also relatively fast and cost-effective compared to traditional excavation and pipe replacement methods. It is important to note that patch lining and continuous lining are not suitable for all types of pipes or damage, and the best repair method will depend on the specific conditions of each case. Here at Redwood, we have a fully trained team of professional pipe rehabilitation specialists to determine the best solution for a given scenario.
