Depth, Flow and Pressure Monitoring

A dedicated sewer monitoring team provide expertise for installing and analysing flow monitoring data. Monitors are typically installed for short durations to determine the flow characteristics and model verification purposes on sewer improvement projects. Permanent monitors can also be installed to help water companies understand and manage their assets in a more pro-active way.

Specialist teams conduct detailed waste water pumping station surveys, combining technical skills with surveying techniques to provide an operating performance curve for each pump sequence. A full test includes calculating and plotting discharge rates at regular intervals to display the pump behaviour throughout the cycle for comprehensive modelling purposes.

To provide greater operating details very precise pressure monitoring of rising mains can be undertaken to enable surge analyses.

Property Investigations

Often during and after stressful flooding periods we provide an onsite service to our client’s customers. We undertake detailed mitigation surveys, including identifying the flooding issue, providing recommendations and completing all the necessary survey works to determine the underlying contributing factors to the flooding mechanism. All survey works are undertaken to an agreed standard and provide suitable evidence for capital flooding schemes. We focus on the highest level of customer service and continuously provide reassurance to the customers.

Grease Traps

Grease traps or interceptors are normally found between a sink/internal waste pipe and the main public sewer and they help to ensure harmful greases, fats and oils are captured and prevented from entering the drainage system where they could cause potentially damaging blockages.

Environmental Health Officers and The Environment Agency are required to see evidence that regular cleaning of grease traps is taking place and any waste that has been removed is disposed of by a regis-tered waste carrier.

At Sewer Surveys UK Ltd our team of specialists use advanced processes to clean your kitchen grease traps thoroughly and efficiently whilst ensuring harmful waste is removed safely and with minimal dis-ruption to your business. In addition to this we also clean out the upstream and downstream drainage pipes using high pressure water jetting techniques.

A full cleaning report is provided on completion of the site works along with proof of waste disposal for evidence to any senior authority.

ISO 14001 – Environmental Management Status

Do you want your company to stand out from a crowded market? Do you want to enhance your companies reputation? Do you want to have a better chance of winning new business? If you answered yes to these questions then the ISO 14001 accreditation could help.

ISO 14001 is an internationally accepted standard that means you have an effective environmental man-agement system in place. Sewer Surveys UK Ltd can help you achieve this by providing you with a full drainage specification report. This will inclue a full drainage connectivity survey, Wincan report and rec-ommendations on any remedial works that are required and how these will help towards achieving your accreditation.

In House Reporting

All surveys carried out by Sewer Surveys UK Ltd are proccesed by our qualified report compilers in house. Our compilers are qualified to OS19X, OS20X and OS21X standard and have many years of expe-rience working with both Wincan V7 & V8 as well as AutoCAD, Infonet and MapInfo.

Our reports can be tailored made to suit the individual clients needs which can include the clients own branding. We have the capabilities to produce reports to the HADDMS Specification including HADDMS Manhole Cards.

All reports will include a coded report using wincan technology, Manhole Cards, PI Photos, an AutoCAD Plan, A DVD including a PDF copy of the Report, all the Site Photos and video footage of the surveys and where necessary we can also produce an executive summary with recommendations.

This report can be used for any company working towards the ISO 14001 accreditation.

Drainage Asset Surveys, Connectivity and Pollution Surveys

As well as CCTV Surveys Sewer Surveys UK Ltd are able to produce connectivity surveys in an area where the drainage is unknown. Dependent on the pipe material, depth and ground conditions we can use a variety of techniques to carry out these including CCTV, GPS, dye testing, sound testing and rod-ding with a Sonde and Locator.

Our engineers on site will map the drainage and draw up a site plan which our in house reporting department will transfer to a DWG/AutoCAD plan.

We are able to locate a pollution source using CCTV Equipment starting at a known point where the pollution has been identified and tracing this back to the exact source.

Manhole surveys can be carried out with internal and location photos, measurements, pipe sizes and depths. GPS can also be added in order to obtain cover levels and invert levels. The manhole surveys can be incorporated into our drainage reports to provide a full drainage survey of a particular site . All manhole surveys are carried out using trained engineers with detailed accuracy and measurements.

Localised or Patch Repairs

On completion of a CCTV survey you may find that there are the odd defects that need to be repaired ra-ther than the whole length of pipe being replaced, if this is the case then Sewer Surveys UK Ltd are able to offer cured in place patch repairs. Patch repairs are a short watertight structural repair sleeve that can be pushed into the defected part of the pipe with rods with no excavation required. There are many advantages to this method, such as:

  • Quick Installation with minimal cost and disruption
  • Bridges and seals gaps and holes, also prevents pipes leaking at connections.
  • Resisitant to chemicals
  • Forms to any shape of pipe and suitable for use in clay, plastic, concrete and pitch fibre pipe.
  • Environmentally Friendly with no damage to the existing surroundings
  • A patch length is between 1000mm and 1500mm and we can use the technique in pipe diameters from 100mm – 600mm
  • Patch Repairs meet WRc Criteria
