Uniform Building Code (USA) The Building Regulations (UK) 3.2 Basic Principles The basic principles and requirements of plumbing and sanitary installations are: 3.2.1 Plumbing System - All pipework shall be easily accessible or traceable and shall be provided with access covers

where necessary. - The design shall be such that defective parts can be removed and replaced easily.


GES B.13 of 20 Rev 0 1999

- Proper testing and commissioning of parts shall be performed to ensure that the system is free

from defects and foreign debris. In addition, plumbing systems carrying foul water drainage shall: - convey the flow of foul water to a foul outfall, that is, a sewer, cesspool, septic tank or settlement

tank; - minimise the risk of blockage or leakage; - be ventilated; - be accessible for cleaning purposes. 3.2.2 Sanitary System - It is essential that foul air is excluded from entering the premises through sanitary installations by

the use of adequate water seal traps. - For all building installations, WCs shall be provided with proper screening and ventilation and

shall be separated from habitable rooms, workspaces and other occupied areas by a ventilated lobby:

(a) As a minimum, one WC and washbasin shall be provided for every 25 employees in

office areas. Where urinals are provided in office areas, WC provision may be reduced to 1 per 35 employees. Additional washbasins (1 per 10 employees) shall be provided in dirty areas.

(b) Cleaner's sinks shall be provided in all buildings. These shall be fitted with bucket

gratings. (c) Designers shall confirm the requirement for eyewashes and emergency showers in any

potentially hazardous work area and as specified in GES H.09. (d) Clinics shall be fitted with purpose made medical sanitary-ware as set out in GES B.09. 3.3 Sanitary Installation - Practical Details In designing sanitary installations, the following points should be noted: - Walls supporting wall-mounted sanitary-ware must be sufficiently strong to provide a secure

fixing. Hollow clay blocks will not be acceptable unless reinforced. - Plumbing pipework shall, wherever possible be contained within an accessible, purpose-made

duct, where it shall be surface mounted. - WC cubicles shall be equipped with hygiene sprays. - WC pans shall preferably be wall mounted to allow for all-round floor cleaning. The cisterns shall

have a 9 litre capacity. - Cisterns shall preferably be contained within an accessible, purpose-built service duct. - Overflow pipes shall discharge to a position where such discharge is visible. - Squatting pans shall preferably be made of stainless steel and be devised to allow the surrounding


GES B.13 of 20 Rev 0 1999

floor to drain into them. - Where showers are provided, the shower heads shall preferably be of the short projection type. - Simple, telescopic-type shower rails shall be provided in preference to screwed in fittings which

are susceptible to damage. - Wash basins shall be firmly fixed on brackets or legs. Washbasins supported on pedestals shall be

avoided. 4.0 PLUMBING AND SANITARY PIPEWORK The design of pipework for plumbing and sanitary installations shall incorporate the following conditions: 4.1 Single-Stack System The single-stack system will be the most widely used form of above-ground drainage for the low-rise

buildings used in the oil industry. The design of any installation will be based on the main stack being large enough under peak flow conditions to limit pressure variations. Such variations may affect the water seals on the sanitary fittings traps. Designers should refer to the principles set out in Figures 1 & 3, in order to ensure that trap seals are maintained.

To achieve an efficient and economical installation when using the single stack system, it is essential that

the layouts of sanitary fittings and service ducts are planned to exclude unnecessary bends and offsets. The main requirements for the system are as follows:

- Sanitary fittings must be grouped close to the stack, so that the branch waste and soil pipes are as

short as possible. - All the sanitary fittings must be individually connected to the main stack with no connection less

than its own diameter above another. This should prevent the loss of trap water seal by induced siphonage or cross flowing.

- An offset shall not occur below the highest branch; this is to prevent compression of air in the

stack. - WC connections shall be swept in the direction of flow, with a radius of at least 50 mm. This is to

prevent the loss of trap seal water due to siphonage of traps connected to the stack below the WC connection. A swept connection helps to prevent turbulent flow of water, with a resultant reduction in air pressure at the highest part of the stack.

4.2 Plumbing Design Particular attention must be given to the following points in the design of plumbing installations: - access; - falls; - venting; - sizing; - planning of pipework routes; - future maintenance. 4.2.1 Access Adequate and accessible access points for installation testing and ease of future maintenance are most

important. Care must be given to the planning of access positions during the design and to coordination of


GES B.13 of 20 Rev 0 1999

the structural, architectural and services elements. 4.2.2 Falls Branch waste runs should be installed with a minimum fall of 1 in 50 to ensure self-cleaning runs to

vertical stacks and to prevent siphonage. 4.2.3 Venting Correct venting of mains and branch wastes is necessary to produce an efficient system and economic

sizing of pipework. 4.2.4 Sizing Correct sizing is essential to give sufficient flows and adequate capacity, thereby preventing pressure

fluctuations in the system. 4.2.5 Planning of Pipework Routes - The layout of the pipework system shall be simple and as direct as possible and the number of

bends, traps and manholes shall be kept to a minimum. - Pipes shall be laid in straight lines from point to point. - Pipes shall be laid to a self-cleansing gradient, that will prevent the settlement of solid matter,

which might lead to blockage. - Pipes shall not pass under a building unless absolutely necessary and pipes shall not be laid close

to building foundations. - Pipes shall not pass under trees because of the possibility of damage by the roots. 4.2.6 Future Maintenance All plumbing and sanitary pipework shall be easily traceable and accessible for ease of maintenance.

Inspections of the system will be carried out on a regular basis to ensure that the systems remain efficient and free from any defects.

4.3 Minimizing Blockages Blockages most frequently occur on horizontal pipework. For this reason, long horizontal runs shall be

avoided by greater use of vertical stacks, and better grouping of sanitary fittings. Other requirements include the avoidance of short radius bends and the provision of plentiful access for rodding purposes. Vendor/Contractors shall refer to Figure 3 for design criteria.


GES B.13 of 20 Rev 0 1999

4.4 Location of Access for Rodding - Rodding access on branch discharge pipes should not be within false ceilings. It is preferred that

the rodding facilities be extended upwards through the floor above - In buildings such as clinics, rodding points should be confined to dirty areas - Where access doors are located on vertical stacks, they should be above the flood level of the

fittings (eg. basin or WC) on that floor, so that any discharge of sewage takes place through the fittings onto non-absorbent floor surfaces.

4.5 Kitchen Waste Attention must be paid by designers to the special requirements for kitchens. A high proportion of starch is

produced by processes such as potato peeling, and preparation of similar starchy food such as rice. The starch solidifies and blocks pipework, when it comes into contact with hot water. It is therefore prudent where possible, to provide a separate waste pipe for potato peeling machines. In addition, for kitchens where rice and other grains form a staple part of the menu, rice-trap interceptors shall be provided. Refer to GES B.07 for fuller details.

4.6 Separation System It is sound practice in plumbing systems to take all ground floor sanitary fittings direct to a drain and thus

connect nothing to the stack below first floor level. This ensures that, if a blockage occurs at the foot of the main stack, water will not back up out of ground floor sanitary fittings and cause flooding.

4.7 Location of Access Points Access points should be installed in a sensible manner, where it is possible to insert and remove drain rods.

Access points shall be provided: - at or near the head of any drain run; - at any change of direction or gradient; - at a junction, unless each drain run can be rodded separately from another access point; - at a change of pipe size, unless this occurs at a point where the drain run can be rodded separately

from another access point; - at regular intervals on long drain runs. 5.0 MATERIALS 5.1 Waste Systems 5.1.1 Cast Iron The metal is widely used for soil and waste systems and has the advantage of resisting mechanical damage.

The pipes are heavy and require good support, but do not expand and contract as much as lead, copper or polyvinyl chloride pipes. The pipes are protected from corrosion by a coating both inside and outside with pitch.


GES B.13 of 20 Rev 0 1999

5.1.2 Copper Copper is an adaptable metal of medium weight. The thermal expansion of copper is higher than that of

cast iron and expansion joints might be required on long runs. The pipe is strong, rigid and resists attack from most building materials, but must be protected where it may contact aggressive materials such as plaster and concrete.

5.1.3 Galvanised Steel This material is extremely strong and resistant to mechanical damage. However the pipe is liable to be

attacked by lime and plaster and should be coated with bitumen if it is in contact with these materials. 5.1.4 Plastics Pipes made of a number of thermoplastic materials are used for soil and waste pipes. These include un-

plasticised poly vinyl chloride (UPVC), polypropylene, modified unplasticised PVC (Mu PVC), chlorinated PVC (CPVC) and acrylonitrile butadiene styrene (ABS). The pipes are light in weight, easy to handle, have a smooth internal bore and are highly resistant to corrosion. Plastics in buildings shall be installed in a fire protected duct.

As a rule, waste pipe systems in ordinarily UPVC, should be confined to overflow systems from cold water

storage tanks, vent pipes and those installations which clearly cannot have hot effluent introduced into them.

Polypropylene is a very suitable material for laboratory waste systems. It has a high degree of resistance to

almost every chemical reagent likely to be encountered. Designers should note that this material has a high coefficient of expansion, and must therefore strictly follow manufacturers' fixing instructions.

Chlorinated PVC is the most suitable and preferred material for waste systems, with good resistance to high

temperatures and a wide range of chemicals. 5.2 Water Distribution Pipework Water distribution pipework shall consist of MuPVC or CPVC although copper piping to BS 2781 is

acceptable. 6.0 INSPECTION 6.1 Inspection Procedures The inspection requirements are covered by the Purchase Order/Contract. Additional requirements are

listed below: - The Vendor/Contractor shall allow the Inspector free access to all areas of assembly installation

and testing. - The Vendor/Contractors has the responsibility to provide adequate control and inspection of

equipment and materials. Any inspection by the Owner or his Inspector shall not relieve the Vendor/Contractor of these responsibilities or those under the Purchase Order/Contract.

During construction and installation, inspection and tests will be required for all aspects of plumbing and

sanitary work. Vendor/Contractors shall set out detailed schedules for this in the design proposals and include adequate time for testing and inspection within their contract programmes and documentation.


GES B.13 of 20 Rev 0 1999

7.0 TESTING A visual inspection shall be carried out on all sanitary and plumbing installations to ensure that foreign

debris has been removed from the system and that all pipes are truly aligned and at proper falls. Air or water tests shall then be carried out to establish the soundness of the system. All testing shall be carried out in accordance with the codes published by the CIBSE and BSRIA or similar approved body. The work shall be carried out by staff qualified in this field. Hydraulic tests shall be carried out on all water distribution systems to twice the working pressure and held for two hours minimum.

7.1 Air Testing Above ground drainage runs shall be tested by means of a three minute air test at a pressure equal to 38mm

water gauge. To apply the test, the water seals of all sanitary fitments shall be fully charged and test plugs inserted into the open ends of the pipework to be tested. One testing plug shall be fitted with a tee piece with a cock on each branch. One of the branches shall be fitted with a manometer by means of a flexible hose. Air shall then be introduced into the system through the other branch of the tee-piece until the manometer scale indicates the desired pressure.

7.2 Water Services: System Sterilisation On completion of domestic water services and after all testing is complete, the entire water distribution

installation shall be thoroughly sterilised, in accordance with BS 6700 i.e: - all storage tanks, calorifiers and hot and cold distribution services shall be thoroughly flushed with

clean water before being refilled; - chlorine-based sterilant shall be added to the whole system to obtain a minimum level of 50 ppm

of chlorine to water; - testing should be carried out and additions of sterilant made to ensure that the entire system

remains charged with chlorinated water at the above level for a full 15 hours. 8.0 DOCUMENTATION 8.1 Introduction 8.1.1 This section covers the documentation required for the design, selection, inspection and testing for all the
