Civil Engineering - Pump Drainage Systems

active, Most Current
Organization: LUL
Publication Date: 1 December 2011
Status: active
Page Count: 32
scope:

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

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

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

Rehabilitation works are proposals that constitute major change to an existing pump drainage system. It therefore generally excludes simple like-for-like replacements of individual assets within the pump drainage system. The exception to this rule is the renewal of a control panel, when this is planned it constitutes major change.

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 covers the design of pump drainage systems, which includes the following principle elements:

a) Hydraulic and structural design of internal and external pump drainage systems (foul, grey and surface water). It should be noted that both buried and nonburied pump drainage assets are designated as Civil assets.

b) Power and control system requirements associated with pump drainage systems.

This Standard should be read in conjunction with the following LU and Non-LU technical specifications:

a) T0002 Civil Engineering - Pump Drainage Systems

b) T0003 Critical Pump Sites - Control Panel Specification

c) T0004 Non-Critical Pump Sites - Control Panel Specification

d) Site-specific application of the National Building Specification (NBS) (in relation to Stations, Depots and other operational buildings pump drainage systems) by the Premises team

The aforementioned specifications state the generic and site-specific materials and workmanship LU requirements.

Purpose

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

Standards for gravity drainage systems are given in London Underground (LU) Category 1 Standard S1052 Civil Engineering - Gravity Drainage Systems.

In defining requirements specifically applicable to pump drainage system assets, this Standard complements LU Standard S1050 (formerly 1-050) that defines mandatory requirements generally applicable to all Civil Engineering assets including pump drainage system assets.

A supporting Manual of Good Practice G056 gives guidance and information specific to LU pump drainage system assets.

There are references within this document to LU Technical Specifications (T-series documents) and within LU they shall be complied with. However, it is not mandatory for other companies within the TfL family to follow them; they may refer to their own company's equivalent specifications.
