The Drain Repair Book has become the definitive guide to the repair of private drainage systems since it was first published in 2003. It is widely used by both insurers and drain repairers. This 4th edition has been developed once again as the result of a collaborative approach from the key stakeholders to provide additional best practice guidance on sewage treatment systems. The Association of British Insurers represented by key members of the Property Claims Working Group and a group of drainage specialists have worked with WRc to update the Book to meet the needs of the industry.

New environmental legislation in the areas of the United Kingdom regarding private sewage treatment systems have highlighted the continuing need for a clear best practice guide when undertaking work on private sewage treatment systems to ensure work is undertaken to correct standard to comply with legislation and to prevent pollution of the environment. The Drain Repair Book is well tried and tested and this edition provides fine-tuning and clarification of the 'Best Practice' that is recognised as the way forward for improving and standardising work. It sets the standard against which organisations and individuals are measured and helps create a level playing field for the competitive drainage industry. Therefore, this document, which has been produced by WRc plc, is a highly-essential part of developing consistency and good, appropriate standards of repair work.

This Book is split into three sections;

• How to assess responsibility of the drain or treatment system
• Inspection and condition assessment of drains including a specification for drain repairs
• Non-mains sewage treatment including septic tanks and small sewage treatment plants.

Benefits:

• Provides you with best practice methods to help you 'get it right first time'
• Guides surveyor and insurers to understand how to correctly investigate and repair damaged drains and off mains systems.

Inspection of sewer condition is an important feature of the management of sewer and highway drainage systems. Such surveys generate large amounts of data which must be recorded and stored.

The Manual of Sewer Condition Classification (MSCC) is the manual used by the UK water industry and other organisations to classify defects in sewers and is crucial to the management of investment in over 500,000 km of public sewers and lateral drains in the UK.

The Manual of Sewer Condition Classification was first published in 1980 to provide a national standard defect coding system for this type of survey work. The fourth edition of the manual in 2004 was a major update to describe the use of what has become the National Equivalent coding system listed in BS EN 13508-2:2003. In addition, some new codes were added and the use of the manual for reference purposes was emphasised. It also describes in detail the simplified coding system listed in the Drain Repair Book. 

This edition of the manual has been extensively updated to reflect amendments to BS EN 13508-2 in 2011 and to take account of the move from video tape to computer storage of video data.

In this latest revision, some of the codes relating to drains and sewers and manholes and inspection chambers have been modified and new codes specifically relating to lining observations have been introduced, in accordance with European standard. Furthermore the change facility, which was a feature of the coding system up to the 3rd edition, has been restored as this has now been included in the European Standard.

• Features in the Manual of Sewer Condition Classification 5th Edition include:
• Review of controls for camera set-up

Updates in line with BS EN 13508-2
