• Drain Maintenance

    When it comes to your drainage system, Grey-Water Drainage firmly believe the best course of action to prevent emergencies arising is to regularly clean and understand the state of repair it is in.

    Maintaining your drainage system should be like testing your fire alarms or servicing your car. You need your drains 24/7. Drainage maintenance will save you money in the long run and prevent emergency issues and costly call-outs and potential damages.

​Storm Drain Maintenance, Aco & Slot Drains

Storm Drain Maintenance
Aco drains and storm drains prevent rain water from accumulating on flat surfaces by safely channeling it into main drainage systems. Unfortunately and all too often, they remain unmaintained and can routinely become blocked with mud, silt, sticks, trash, and various other forms of debris when these objects manage to find their way through the protective grates. These blockages can cause business estates and roads to flood, which can lead to major water and property damages in a very short amount of time. Where aco drain cleaning takes on a shallower and longer space, we will use different equipment types than we would for storm drain cleaning, which focuses water into a deeper sewer system. We provide commercial and residential storm drain cleaning in the London and Kent area.

Public Highway Drain Maintenance  

We are ready and on-call for any disruption to any Public Highways England stretch of road. This includes residential or commercial storm drain maintenance requirement. No matter the weather condition, you can count on us when you need it most.

Fast and Efficient

It is unlikely we will find an issue we haven't encountered before and with our specialist team and equipment, we are clearing drains in the shortest time possible.

Reduced Cost

Finding faults, providing solutions, saving you time and money, because we know where to look and what to do in an emergency.

Flood Prevention

If you're concerned about a drain causing a flood, it's better to call sooner rather than later. It will be easier to access and quicker to clear, and we will get there before the water reaches your property, or blocks property or a highway.

Storm Drain Cleaning
Storm drain systems need to be cleaned regularly, especially during periods and seasons with high rainfall. The Grey-Water team clean efficient, accurate, and use our high-pressure jetting methods to safely unclogs grease, sludge, sediment, mineral deposits, debris buildup, and tree roots in storm drains by utilizing a high pressure water jet into the area. The high pressure jetting is propelled via specialized nozzles through the line, breaking up the sand, silt and debris, pushing it back toward the vacuum hose or tube. The mixture is then extracted by a powerful vacuum and deposited into one of our debris tanks to remove it from the system. The end result is a storm drain system that is free of buildup and pipe walls that are thoroughly cleaned, making them less likely to be blocked in the future, which could cause flooding and water damage at home or work. At Grey-Water Drainage, we have extensive experience with cleaning and maintaining storm drains - from regular cleanings to severe blockages, we are on-hand to get you back in your flow.
Storm Drain Maintenance
Fixed periodically, cleaning your storm drains can significantly reduce your probability of backups, clogs, and flooding. Most businesses should be fine with having their pipes jetted a couple of times a year, but restaurants and other food-service establishments should have their pipes jetted quarterly, or even monthly.
Storm Drain Inspections
Storm drains should also be regularly inspected to ensure they are working and functioning properly and are not at risk of causing any issues following a sudden downpour of rainwater. At Grey-Water Drainage, we are experienced in the maintenance and cleaning of your storm lines, using our industry-leading technology, paired with our extensively trained engineers to give you thorough inspections and high levels of customer service.

Contact us today if you need an expert team to clean, maintain, or inspect your storm drains, ensuring they are operating as efficiently as possible.
