Organization: LUL
Publication Date: 1 July 2010

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:

a) Inception and design;

b) Construction, installation, testing and commissioning;

c) Inspection;

d) Analytical assessment;

e) Condition assessment;

f) Maintenance;

g) Upgrading and Renewal;

h) Decommissioning;

j) Evidence of compliance;

This standard replaces 1-052 A1.

This standard supports the following LU policies;

Note: The identification of Policies shown below shall have no material impact upon Infraco or other Suppliers beyond the obligations already contained in this Category 1 Standard. They are provided for LU reference purposes only.

Purpose

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

a) Track and off track drainage systems;

I) Gravity pipes - Non Brick;

II) Gravity pipes - Brick;

III) Venting pipes;

IV) Catchpits;

V) Manholes;

VI) Soakaways (Non Sub surface railway stations areas only);

VII) Flow control device;

VIII) Storage tanks;

IX) Channels;

X) Syphons;

XI) Gratings;

XII) Pipe crossings up to 600 mm nominal bore;

XIII) Open ditches (Non Sub surface railway stations areas only);

XIV) Screens (Non Sub surface railway stations areas only);

XV) Oil interceptors;

XVI) Sumps;

XVII) Interstices between the pipe bedding;

XVIII) Trench backfill.

b) Station drainage systems;

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

II) Venting pipes;

III) Manholes;

IV) Inspection chambers;

V) Channels;

VI) Gullies;

VII) Gratings;

VIII) Grease traps;

IX) Oil interceptors;

X) Drip trays;

XI) Sumps;

XII) 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.
