Civil Engineering - Gravity Drainage Systems

active, Most Current
Organization: LUL
Publication Date: 1 September 2011
Status: active
Page Count: 36
scope:

This standard applies to new and rehabilitated gravity drainage system assets (foul and surface water) owned by LU as part of the following drainage systems:

a) Track and off-track gravity drainage systems (surface water only).

b) Stations, depots and other operational buildings gravity drainage systems (foul and surface water).

c) Other gravity drainage systems (foul and surface water).

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

a) Design

b) Construction

c) Maintenance (including Inspection and Assessment)

d) Decommissioning

This Standard should be read in conjunction with LU Technical Specification T0001 Civil Engineering - Track and Off-track Gravity Drainage Systems and any relevant site-specific application of the National Building Specification (NBS) (in relation to Stations, Depots and other operational buildings gravity drainage systems) by the Premises team. The aforementioned specifications state the generic and site-specific materials and workmanship LU requirements.

This Standard also covers flood protection requirements to LU assets.

Purpose

The purpose of this Standard is to define the life cycle requirements for gravity drainage system assets in performance terms.

This standard also covers hydraulic and structural design of internal and external building gravity drainage systems (foul and surface water - including roof drainage). It should be noted that buried drainage assets are generally designated as Civil assets and non-buried drainage as Premises assets (except pump drainage assets which are also generally designated as Civil assets). 

Standards for pumped drainage systems are given in London Underground (LU) Standard 1-056.

In defining requirements specifically applicable to gravity drainage system assets, this Standard complements LU Standard 1-050 that defines mandatory requirements generally applicable to all Civil Engineering assets including gravity drainage system assets. 

A supporting Manual of Good Practice G-052 gives guidance and information specific to LU gravity drainage system assets.
