How we maintain sewers

Leaking pipes repaired
We ensure the proper functioning of sewer systems and prevent issues that are known to occur in these environments, such as blockages and overflows.
We provide commercial and residential storm drain cleaning in the London and Kent area.

Regular Inspections

We conduct routine inspections using specialised cameras to assess the condition of sewer pipes. These inspections help identify blockages, cracks, root intrusions, and other potential problems.

High-pressure Jetting

To clear blockages and remove debris from sewer pipes, we use high-pressure water jetting equipment. This involves directing a powerful stream of water into the sewer lines to dislodge clogs and flush out material.

Root Cutting

Tree roots can invade sewer pipes, causing blockages and damage. We use cutting tools to remove these roots and prevent further issues.

Odour Control

Sewer systems can produce foul odors, especially in warmer weather. Drainage companies may use odour control methods such as chemical treatments or activated carbon filters to reduce unpleasant smells.

​​Gully cleaning

Leaking pipes repaired

Gullies are typically found along roadsides or in urban areas, designed to collect surface water runoff and direct it into the public sewer system or drainage network. A gully consists of a grated or slotted opening connected to an underground channel. Their primary function is to intercept rainwater and prevent it from pooling on road surfaces, reducing the risk of flooding and ensuring the continuation of safe driving conditions. Gullies play a vital role in preventing blockages and maintaining the flow of wastewater. By capturing surface runoff and directing it into the sewer system, gullies help to prevent the accumulation of debris, sediment, and pollutants in the drainage network. This approach to managing stormwater ensures the efficient operation of the sewer system, minimises the risk of sewer backups, and promotes a healthier environment for the community.


Regular inspection and maintenance of gullies are essential to maintain their functionality and contribute to the overall health of public sewer infrastructure. At Grey-Water, our professionals use quality equipment to clean gully drains of blockages and flood risks, keeping public infrastructure safe as a result.

​​Storm Drain Maintenance, Aco & Slot Drains

A storm drain lets in flood water and leafy debris.
The importance of these public drain systems and why they need maintaining.
Aco drains and storm drains prevent rain water from accumulating on flat surfaces by safely channelling 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. It is always wise to seek a CCTV drain survey report when concerns for storm drain blockages occur, as it's better to ascertain a fix sooner rather than later to prevent flooding; a storm drain survey will cover all bases. 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.

Regular storm drain overview

There are a few ways in which we ensure storm drains are working throughout the year:

 Storm drain cleaning 

Storm drain systems need to be cleaned regularly, especially during periods with high rainfall. We are efficient and accurate, utilising high-pressure jetting methods to safely unclog grease, sludge, sediment, mineral deposits, debris build-up, and tree roots in storm drains with a high pressure water jet. The high pressure jetting is propelled via specialised nozzles, breaking up the sand, silt and debris. The mixture is then extracted by a powerful vacuum and deposited into one of our debris tanks to remove it from the system. With pipe walls thoroughly cleaned, they are less likely to clog later on, reducing flooding and water damage at home or work.

 Storm drain maintenance 

Evaluated and fixed periodically, cleaning your storm drains can significantly reduce your probability of back-ups, clogs, and flooding in all environments. 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. Our technicians are well-trained to carry out general and specialist maintenance tasks to storm drains in the areas we service.

 Storm drain inspections 

Storm drains should be regularly inspected to ensure they are working and functioning properly and are not at risk of causing any issues following rainwater downpour. 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.

Frequently Asked Questions
When should public sewer operations be undertaken?

Public sewer maintenance operations should be undertaken regularly and proactively to ensure the efficient functioning of the sewer system and to prevent potential issues. The frequency and specific timing of these operations may vary depending on factors such as the size of the sewer system, the volume of wastewater it handles, and the environmental conditions.

How much does sewer maintenance cost?

The cost of public sewer maintenance can vary significantly depending on various factors such as the size of the sewer system, its age and condition, the specific maintenance activities required, labour and material costs in the region, and the frequency of operations. Our rates are more accurately gauged with a preliminary inspection.

Do I have to pay in advance for sewer maintenance?

Due to previous experiences, we ask for payment in advance of sewer maintenance and after a preliminary inspection.

Do I need sewer maintenance?

Whether or not you need sewer maintenance in your area will depend on factors such as if you are experiencing frequent blockages, slow-draining fixtures such as sinks and showers, if you can smell any foul odours or hear any gurgling noises coming from the sewer line, if there are sewage backups, along with a host of other indicators.

Responsibility for maintenance typically lies with the public sewer authorities. As a homeowner or business-owner with a physical premises, you should be aware of any signs of potential problems with your sewer system and report them for prompt action.

Is there a local sewer maintenance service near me?
