Removing the source of dis-colourisation from Drinking Water Pipelines

Cleaner Pipelines, Improving Drinking Water Quality
Are you looking for an innovative method of removing Iron, Manganese and other sediments from Drinking Water pipelines that's proven to be more efficient than flushing?

An important piece of any cleaning programme is one that can define a new era in drinking water pipeline cleaning across the globe. We can remove the source of discoloured water in Cast Iron or Bitumen lined pipelines, i.e. removing the particulate material that gives you the 'brown water' you see coming out of your tap.

A debris lift gel can capture, retain and remove the particulate matter leaving the pipeline clean plus eliminating any non-compliance issued caused by aggressive cleaning.

The gel can capture, retain and remove the particulate matter leaving the pipeline clean along with eliminating non-compliance after effects caused by aggressive cleaning.

We have proven that regular flushing with clean water is inefficient and that with the use of a gel, the pipeline will remain cleaner for longer, plus significantly reducing the vast volumes of water required in the cleaning process.

"Reduce operating costs with a non-aggressive deep clean"

  • Risk Assessment
  • Benefits
  • Properties
  • Trials
  • Regulation

A plug and play system

The plug and play process for gel injection has been kept as simple as possible allowing for rapid mobilisation and all year round cleaning.

  • Isolate the section of water main you require cleaning
  • Inject the desired volume of gel relative to the pipeline variables
  • Use the water source to propel the gel slug along the pipeline
  • Remove the gel + Iron/Manganese/Debris
  • Test the water quality and return the pipeline into service

Data Analysis and Risks

We can work with you to ensure that sufficient data analysis is gathered so you can make the appropriate risk assessments regarding the use of gel in clean water pipelines. The gel is proven to leave no residues.

  • We provide the correct product for the right application
  • We work with you to ensure your standards are maintained
  • We ensure no residues remain after cleaning
  • We provide the onsite technical delivery team


Based on 'live trials' we know the gel cleaning approach has the following benefits:

  • Remove's Iron & Manganese
  • Applied to any system
  • Highly effective
  • Injected and removed through a hydrant
  • No limit on transit distance
  • Supplied all year round
  • Small operational footprint
  • Save vast volumes of water compared to flushing


Viscous gels are a bespoke product used in removing material's from pipelines. Below is a list of more information about using a gel to clean drinking water pipelines:

  • Biodegradable
  • Supplied 'ready to go'
  • Full bore cleaning
  • Propelled by water at source
  • Non-aggressive
  • Disposed of at a treatment works

Industrial Trials

If you are looking to undertake a trial please contact gels@intelligentgels.com to discuss in more detail. We can provide a full and in-depth presentation to your company.

Anglian Water

Anglian Water experienced an interruption to supply in the local area of the main used in this project. If the interruption to Supply ODI was in effect it would have been a significant scoring event.

After an investigation they concluded that if they had the main used in this project was in service they would have mitigated that supply interruption.

Anglian Water had no options capable of cleaning a bitumen/coal tar lined main available.
Total Iron content reduction 10.5mg/l to 0.09mg/l
Manganese Issues? We obtained a 10 fold reduction
Turbidity Issues After Cleaning? We reduced turbidity from 56.4NTU to 0.7NTU
Got an issue with PAH? We reduced PAH levels from 4.99ug/l to 0.03ug/l
Please email gels@intelligentgels.com for more case study information.

Regulation Compliance

The regulation's are clear and defined. Please contact us to discuss further.

Rising Main Cleaning

Improve pumping efficiencies and lower the risk of pollution events

Are you looking to reduce energy costs, improve pumping efficiencies and lower the risk of pollution/flooding events to homes and businesses?

Our plug and play system is proven to remove sediments from rising mains within the sewer network.

The problem with rising mains is that they can lose the ability to self-cleanse. In a neglected network there is a built up of sediments thus reducing the pumping capability and the ability to maintain self-cleansing status. This also increases the energy costs and increases the probability of a pollution event.

As you can imagine, there are thousands of pumping stations across the UK and many of them are not deemed to be self-cleansing. It is a known issue within the sector and one that requires attention.

Cleaning a rising main is not easy to do with existing techniques and the use of gel can improve the network by removing debris thus increasing the pipeline bore, reducing the load on the pumps and increasing efficiency plus reducing potential pollution events.

"All year-round cleaning with a unique Plug and Play system"

  • Simple Operation
  • Why choose a Gel?
  • Disposal
  • Cost Savings
  • Industrial Trial

A plug and play system

The plug and play process for gel injection has been kept as simple as possible allowing for rapid mobilisation and all year round cleaning. Our set up means we can access remote pumping stations and with low volumes of gel required, we can gain access to the most difficult of pumping stations.

Why choose Gel Cleaning?

Using gels in sewer network cleaning has many benefits. Each project is assessed before choosing the right gel as each scenario has it's own set of unique parameters. The benefits of using a gel are:

  • Remove sediments
  • Increase pipeline bore
  • Use effluent as pumping media
  • No additional pressure loading
  • No blockages
  • Low manpower requirement
  • Efficient operation
  • Stop/Start pumping with no effects

Product Disposal

During our testing phase samples were taken for laboratory analysis which included; Alkalinity, BOD & COD, Conductivity, Ammonium, Oil & Grease, pH, & Sulphide.

No known impact was noted at the treatment works during disposal.

Cost Saving

Viscous gels are a bespoke product used in removing material's from pipelines. Below is a list of more information about using a gel to clean drinking water pipelines:

  • Improve energy consumption
  • Reduce flooding events
  • Reduce failures
  • Increased pump life
  • Low-risk option for lines that have had previous failures

Industrial Trials

Yorkshire Water and its partners Morrisons Water Services and Intelligent Gels have successfully trialled the use of gel to remove sediments from rising mains.

The trial saw gel inserted into the wastewater network and used existing pumping within the network to push it through 4km of nine-inch sewers to remove sediment and build up in rising mains.

Mark Gregory, project manager at Yorkshire Water, said: "We are always looking at innovative new technologies to help us manage our networks and make them more efficient.

This successful trial removed sediment from a large section of our network, ultimately helping to protect the pumps, extend their life, reduce the likelihood of failures and the associated customer and environmental impact that can have. This is an exciting development and one we’re looking at using further across our network."

Preventing tree root intrusion into built structures to reduce blockages, prevent flooding and pollution events

The problem of tree root intrusion is endemic across all wastewater service networks across the globe, affecting both homes and businesses alike.

In 2017, Intelligent Gels started a project with Northumbrian Water and Durham University to tackle pollution events that are due to tree roots and the blockages they cause using nature based materials.

In 2022, we have scientifically proven that we can repel tree roots away from pipelines, with a coating that doesn’t affect tree growth.
