SEP Drainage Surveys Ltd are proud to announce they have teamed up with Mini Cam and are able to offer one of the safest Drainage CCTV crawler units in the country. With the changing of standards within the United Utility Region, SEP Drainage Surveys have recently ordered the NEW ATEX rated PROTEUS CCTV unit. The PROTEUS ATEX crawlers have been engineered, built and tested for safe use in some of the most dangerous situations, without compromising on any of the features and benefits.

With the ability to increase wheel size, lighting options and stability. Each survey, no matter what the size of the line will be centralised which in turn maximises the quality of the the information collated, which is then implemented into the CCTV survey report. Following each survey SEP Drainage Surveys Ltd will supply you with a full written report within the WinCan format and a DVD showing all the HD footage taken relating to a fully marked up site drawing.

The new state of the art CCTV units carry four different cameras which enable us to survey lines from 100mm to 1400mm, all in HD. All of our engineers are trained to a maximum standard OX19 (with many having a 0X21X standard) which allows us to survey and brick or concrete line to the highest degree. With 200m of cable length on each unit we are able to survey 400m from one point, increasing the productivity and output per shift. All the HD footage is uploaded onto the WinCan software which enables us to produce simple yet effective reports which include defect severity within a traffic light system so the report can be understood by first time viewers, but also captures in depth data that can be used by professionals.

A major part of our services is pipe maintenance and repair, either to fix existing problems, or to prevent them from developing in the first place. Our ‘no dig’ technology allows us to simply fix pipes and sewers from the inside in most cases, which means minimum disruption and maximum efficiency.


Patch repairs are carried out on individual defects that have been highlighted within the pipes. They are designed to provide a permanent and cost efficient fix with no need to carry out an excavation. With the remediation process for patching taking between 2-4 hours it is ideal for minimising disruption to the local environment as well as being more cost effective than a traditional excavation.


SEP Drainage Surveys Ltd can provide full length repairs which are the best option when it comes to pipes which are structurally unsound throughout or contain multiple fractures. The liners are installed from above ground and cured through either air, water or ultraviolet light.


Each full length repair is specifically designed and made for each individual line. SEP Drainage Surveys Ltd are able to repair and remediate lines from 100mm diameter to 2000mm diameter. Once the repairs have been implemented we are able to reopen any connections and laterals with the use of ta state-of-the-art hydraulically driven cutting unit. Meaning that there is no disruption to the drainage running into the remediated sewer.


We pride ourselves on delivering quality services from start to finish on civil projects across a wide variety of sectors, with access to our own labour, engineers, site supervisors, plant & equipment, we are able to manage civil construction projects largely in-house which in turn allows us to offer a competitively priced, superior service to our clients on construction projects of any size.


Here at SEP we understand capturing accurate current site data is vital to our client’s requirements. To help provide this high end detail, our engineers have been trained in the latest GPS software and methods. This enables our teams to capture associated drainage detail that other methods cannot provide accurately. The GPS method can also be beneficial when drainage items are absent when working from a base plan. This missing information can then be added to a topographical survey or if you wish we can produce a drawing in-house within our own CAD department. Due to the above mentioned digitalisation method, plus our new cloud based service, SEP Drainage Surveys Ltd are able to deliver this high end service within a very short time frame.
