Car Park and Road Gullies are designed to allow surface/storm water to drain away from large tarmac and concrete areas, retaining silt and debris and preventing the deposits from entering the drainage system. Petrol interceptors collect oil and petrol deposits preventing contamination of the surface/storm water. Gullies and Petrol Interceptors need to be emptied and cleaned on a regular basis to prevent the collected deposits overflowing into the surface/storm water system. Drainage & Hygiene Services and Clean Drain utilise a specialist gully emptying unit which is used to empty the gully and petrol interceptor traps and flush through the drain.
Grease traps normally serve kitchen and restaurant facilities of larger premises. Their aim is to filter out and collect fat and grease to prevent it entering the drainage system via the kitchen sinks. The fat and grease separates from the water and collects within the trap allowing the drains to remain clear, reducing costs incurred to the maintenance of the drainage system. The grease floats to the top of the trap, collects and forms a crust allowing the water to flow on through to the drain. The frequency a grease trap needs to be emptied varies dependant on the amount of use and size of the trap.
Channel drains also known as Linear or ACO drainage are commonly found on driveways and paved areas in front of shops and stores. Channel drain s work in a similar fashion to Road gullies and the silt trap needs to be emptied and the drain lines cleaned on a regular basis. This helps to prevent collected deposits overflowing into the surface/storm water system. We use a specialist gully emptying unit which flushes through the drain.
CCTV drain surveys are invaluable in ascertaining the structural and service condition of a drainage system. We have a team of highly qualified and experienced drainage engineers who specialise in the surveying and plotting of drainage systems. This allows us to verify the integrity and flow characteristics of a drain, to confirm position, material and duty of a drain through to purchase/sale documentation.
A typical CCTV camera survey report will contain a detailed condition report and schematic of each drain line surveyed, manhole condition reports including the invert levels of the manholes, a site plan showing the onsite drainage, digital video footage of the drains surveyed, conclusions, recommendations and a quotation to carry out any recommended remedial works. Typically, the report is collated and sent within 5-7 working days of the survey being carried out.
The roots of trees and bushes can cause severe problems within drainage systems ranging from repeated blockages through to complete obstructions or strangulation and collapse of the drain. The treatment of roots within the drainage system is dependent on the severity and extent of the root ingress. The vast majority of root ingress can be treated with the use of specialist root cutting equipment or high-pressure water jetting with specialist root cutting attachments. Upon removal of the roots Drainage & Hygiene Services and Clean Drain will ascertain the condition of the drain. Roots fracture the drain on entry which may cause future problems with blockages as well allowing roots to re-grow through the cracks. In most cases it is recommended that a GRP liner is inserted into the drain after root removal to seal the drain and return it to a watertight condition, the GRP liner will also help to also prevent the re-growth of the roots into the drain. In severe cases where the roots are very thick or the drain has been strangled causing the drain to collapse, the section of drain affected is removed and a new section inserted.
