Cover Page
This is the front page of a standard Viewline report. The top right area consists of our WRc (Water Research Centre) approval for our reporting format. WRc Approval describes Viewline 550 CCTV sewer inspection software as a program designed, ‘… for the reporting of observations and defects in domestic drainage systems. The program uses the domestic drainage codes specified in the Manual for Sewer Condition Classification 5th Edition (MSCC5) and EN13508-2.’ Our certificate details can be found here.
The site address and client details can be found just below. An image of the property being surveyed can also be added.
The bottom section includes the drainage contractor’s details. Below this information there is some colour coded information on the condition of the drainage sections surveyed.
The lower right corner contains grading information for each drain run surveyed. The grading system used is based on the WRc Drainage Repair Book (DRB) grading system. Green represents a serviceable drain, amber relates to a drain that may require attention and red relates to a drain that requires remedial works. The numbers represent the number of each of these graded drains. This provides an at a glance indication of the condition surveyed drains on the first page of the report.
The colour coded information located to the bottom left indicates the total number of recorded defects for the project and is based on severity score.
What does DRB grading mean?
DRB grading is based on WRc recommendations on drain serviceability. When a drain is in good condition with no issues that will affect the operation of that drain it is deemed serviceable. A serviceable drain is given a Grade A. If there are issues with the drain likely to affect the drains operation, then it is given a Grade C, which means the drain is unserviceable and requires repair. The area in between, where the defect might require repair in the near future but is still relatively serviceable is given a Grade B.
We have added to DRB grading by using a traffic light colour coding system whereby Grade A is green, Grade B is amber and Grade C is red. This is aimed to enable clients to understand the general condition of their drainage system easily.


Project Page
This page contains the project information, which includes the contractor details, Client Information and Site Information. There is also an area at the top of the Project Page for the project name and date of report. The contractors logo can also be located at the top left of the page.
Colour coded information on total number of defects and DRB grades is duplicate at the bottom of the report.

Report Interpretation
This part of the report provides an area to describe the report contents so that the end user can fully understand the output. This part of the report comes with default text supplied by Viewline but can be edited by the license holder if required.

Overview Page
The Overview page provides an at a glance preview of the condition of the the complete survey broken down by section.
Again Viewline provide colour coded indications as to drain system condition. In the example to the right, Section 1 indicates a drain in Grade B (indicated with the colour amber) condition with a manhole issue (indicated with a red block). There is additional room to include a short description of the issues affecting the drain.
Section 2 describes a Grade C graded drain, indicated using red, that has a good condition manhole, indicated with a green block.
Where the term ‘Misconnection’ is used this indicates that the drainage system is separate and the foul water has been connected to a surface water drain.
As a double check it should also be noted that the ‘Total DRB Grades for Project’ section located bottom right should tally with the Overview sections.
The Overview page enables end users to identify the areas of the drainage system that require attention quickly.

Section Report
The upper section detail contains the header information. This information is based on WRc header recommendations. This includes base information on the pipe being surveyed such as the start and finish node references, direction, use, material and dimensions. The Viewline report header format also includes basic manhole condition information concerning cover, benchwork and half channel condition.
The observation detail is located beneath the header information includes a pipe line graphic with indications as to the position of each observation. To the left of this is the position of the defect or observation, the associated code and the long hand description of the observation. If an image has been captured, its reference number is then included next to the position video reference number. Defects are also colour coded according to the DRB, so amber if Grade B and red if Grade C.
The lower right corner contains grading information for the section. The grade is based on the highest severity defect, in this case the highest graded defects are all Grade B.
The colour coded information located to the bottom left indicates the total number of recorded defects for the section and is based on severity scores.

Observation Image Page
This page shows the images taken by the operator of defects or any area of interest. These are referenced in the previous section report and are designed to show the defect for easier interpretation. The distance position, video reference position, code and long hand description are also shown.
It is also possible to show all the observation images at the end of the report.
Again the lower right corner contains grading information for the section. The grade is based on the highest severity defect, in this case the highest graded defects are all Grade B.
The colour coded information located to the bottom left indicates the total number of recorded defects for the section and is based on severity scores.
The report will then show each section surveyed in this fashion, (section header followed by section header) until the final surveyed section.
