Publication Date: 1 October 2007

scope:

This standard applies to Gravity Drainage System assets owned by LU.

This Standard defines the responsibilities involved during the life cycle of the assets and sets out the requirements for:

Inception and design

Construction, installation, testing and commissioning

Inspection

Analytical assessment

Condition assessment

Maintenance

Upgrading and Renewal

Decommissioning

Evidence of compliance

This standard replaces 2-01304-003 A1. The Standard has been re formatted and renumbered. There were no technical changes.

Purpose

The purpose of this Standard is to define the life cycle requirements for Gravity Drainage System assets. These assets comprise:

Track and off track drainage systems

Gravity pipes - Non Brick

Gravity pipes - Brick

Venting pipes

Catchpits

Manholes

Soakaways (Non Section 12 areas only)

Flow control device

Storage tanks

Channels

Syphons

Gratings

Pipe crossings up to 600 mm nominal bore

Open ditches (Non Section 12 areas only)

Screens (Non Section 12 areas only)

Oil interceptors

Sumps

Interstices between the pipe bedding

Trench backfill

Station drainage systems

Gravity pipes (including those carrying grey and/or foul waste from sanitary ware)

Venting pipes

Manholes

Inspection chambers

Channels

Gullies

Gratings

Grease traps

Oil interceptors

Drip trays

Sumps

Flow control devices

This standard does not cover building drainage, sanitary ware, roof drainage, guttering or down pipes. These are dealt with in LU Standards 1-068 (Station and Mechanical Services, Utility Provision and Energy Management), and EME-ST-01-018 (Mechanical Services Design).

Requirements for Pumping Systems are given in LU Standard 1-056 (Civil Engineering - Pumping Systems).

In defining requirements specifically applicable to Gravity Drainage System assets, this Standard complements LU Standard 1-050 (Civil Engineering - Common Requirements) that defines mandatory requirements generally applicable to all Civil Engineering assets including the Gravity Drainage System assets.

A supporting Manual of Good Practice G-052 gives guidance and historical information specific to LU Gravity Drainage System assets.
