4. ABOUT SEP DRAINAGE
4
For 30 years, SEP has been supplying Engineering and
Surveying Services to clients across the UK and
Overseas. During this time we have grown steadily to
become one of the largest independent surveying
companies in the field. We have recently decided to
create SEP DRAINAGE SURVEY Ltd to accommodate
the needs of our customers with drainage requirements
whilst enabling us to develop other working relationships.
SEP Drainage Surveys Ltd is a specialist drainage
surveying company that is set up to meet the various
and sometimes diverse needs of high end drainage
surveys. Offering bespoke surveys that are both practical
and user friendly to a wide range of clients such as
consulting engineers, design consultants, FM
companies, construction companies and highways
agencies. We tailor our surveys to meet the needs and
specification of each individual project and understand
how to achieve the most efficient survey to maximise
the level of data captured. Following years of experience we
understand that not every drainage survey is carried out
to capture the same information. Generic surveys are
often carried out which means that sometimes the vital
data that the end user requires is missing. We realise
that each project is specific, and the information and
classification of the survey needs to change in order
to meet the customer’s needs and overall plan.
As well as detailed drainage surveys. SEP Drainage
Surveys Ltd also offer the complete solution to any of
your drainage needs, with the availability to clean,
unblock and remediate. We are a one stop shop for any
drainage problem that might occur.

CCTV INVESTIGATION
SEP Drainage Surveys Ltd have invested in brand new
surveying units. The CCTV units carry the latest
ibos system which can be tailored to meet the intended
drainage diameter. The brand new CCTV units can survey
from 100mm up to 1400mm in diameter, incorporating the
latest Wincan reporting system. The ibos crawler units have
the highest specification lens within the drainage industry,
resulting in HD quality images with a capability to zoom in at
10 times the standard viewpoint. The viewing functions of the
unit takes away the responsibility of the engineer and puts it in
the hands of the technology. Meaning each survey runs
smoother and results in a more comprehensive report.
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
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.
Invert Level Diameter Location Condition Flow Usage Material Profile Lateral Location
Connectivity Structural Integrity Asset Identification Defects Manhole Cards Water Infiltration

7. Whilst carrying out most surveys it is imperative that we
locate and highlight the exact positions and depths of the
various lines. SEP Drainage Surveys use the highest
specification sewer Sonde which enables us to trace the
location and depth of lines up to 13 meters deep. The sonde
fits to the back of the crawler unit and is traced above
ground. By marking out the exact positions and recording the
data using our in-house GPS and CAD teams, you are
guaranteed to get the accuracy that you require.
Along with the new camera units, we have also backed this
up by teaming them up with advanced Jetvac units that have
the capability to jet at 2200PSI and with a suction capacity of
1200 CFM, powerful enough to remove liquid from more
than 50 metres away.
Due to most of the surveys we conduct being prior to the design stage,
we are aware that the level of information that needs to be captured
is far more in-depth than that of a standard survey. In order for us to
capture this information we provide manhole cards for each survey
carried out which allows the end user to understand the exact
parameters that they have to work with.
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 minimum standard OX19 (with many having OX21X standard) which allows us to
survey any 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.

SUCTION CAPABILITIES
JETTING CAPABILITIES
Thanks to years of experience in performing technical operations on drainage systems, we understand the importance
of good quality equipment when it comes to providing a thorough service. Due to these reasons SEP Drainage Services
have procured state-of-the-art Jetvac systems. The units have a capacity to jet at 2200 PSI with a suction capacity of
1200CFM, powerful enough to remove liquid from more than 50 meters away. All SEP Drainage Surveys Ltd jetting
engineers are trained to the highest standard, and incorporating this with our membership with Water Jetting
Association and National Sewerage Association means that we maximise the capability of the machines. Resulting in
less timeon site.
At SEP Drainage Surveys Ltd, our vacuum and
Jetvac units include ‘Vactor’ Tankers which
feature an unrivalled ability to cleanse pipes,
sewers, manholes chambers and culverts
from 400mm to 4000mm above diameters.
With an 80 GPM flow at 2200 PSI, the jetting
facility complements the suction to ensure that
we are able to manage even the most daunting
cleansing projects.
The units are ideal for such tasks as gully
cleansing, interceptor emptying, liquid removal
and the cleansing of fat traps. All of which can
be covered under one of SEP Drainage Surveys
Ltd planned maintenance schemes.

In recent years SEP Drainage Surveys Ltd has seen the need for planned maintenance schemes increase dramatically.
By being able to tailor the scheme to meet any of our clients needs we are able to reduce the amount of unwanted
blockages which minimise the impact upon the day to day dealings of your business. Whether during school holidays
or production shut off periods, each scheme is specifically designed to maximise the efficiency of the drainage system
whilst minimising the costs. With all the relevant licences we are able to provide a full service to comply with legislation.
We offer a complete waste management system across a diverse range of situations from food processing plants to
heavy industry sites dealing with disposal of everything from hazardous waste to grease and petroleum products.

SEWER & PIPE REMEDIATION
BEFORE
AFTER
PATCH REPAIR
FULL LENGTH REPAIR
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 a state-of-the-art hydraulically driven cutting unit. Meaning that there
is no disruption to the drainage running into the remediated sewer.

11. MANHOLE SURVEYING
SEP Drainage Surveys Ltd understand that capturing the current data from sites is always crucial to the project.
With each survey that we carry out we are able to offer manhole cards as standard, listing pipe inlet locations, cover
details, construction make up, condition information, location sketches, photographs and plans.
11
We are also able to offer if required
indepth 3D modelling of any manhole
chambers, interceptors, tanks, wet
wells with the use of our Laser scanner.
The scanner can be inverted to a depth
of upto 10 metres eradicating the
need for manhole entry and all the
Health & Safety issues that are
connected. We are also able to capture
a thousand times more data in a
shorter amount of time.
This is because a laser scanner records
approximately one million measuring
points per second and produces a
precise, three dimensional image of its
surroundings. With suitable plugins, this
image can be directly imported into a
wide range of software applications.
