TS 112 - Process and Instrumentation Diagrams (P&ID)2SA Water - Technical StandardScopeThis Technical Standard (TS) shall apply to all the Process / Piping and Instrumentation Diagrams(P&IDs) produced for or by SA Water, and for all SA Water projects.SA Water requires P&IDs to be prepared at the Concept Design stage for all plant and systems thatinclude operable elements or instrumentation. Operable elements include manual, actuated, andautomatic operation. P&IDs may be prepared prior to the Concept Design stage as appropriate.P&IDs shall be revised for each subsequent phase of the project or works.This Technical Standard specifies P&ID content and format, and particular SA Water requirements. Itis generally consistent with Australian and International Standards and with water industry practice.Reference to this Technical Standard shall also be taken to include reference to SA Water Drawings4003-00001-01 and 4003-00001-02. Reference to drawings shall also be taken as reference todrawing sheets. Refer to TS 95 for explanation of the SA Water drawing-and-sheet system.This Technical Standard and SA Water Drawings 4003-00001-01 and 4003-00001-02 supersede allprevious SA Water documentation on this subject.3PrecedenceWhere symbols or codes differ across the relevant standards the following order of precedence shallapply, in descending order: SA Water TS 112 and supporting Standard Drawings 4003-00001-01 and 4003-00001-02 Australian Standard 1101 (as current and applicable) ISO Standard 3511 Custom symbol or code4P&ID Requirements4.1 IntroductionA P&ID shows information on piping, fittings, equipment, instrumentation, and process plant in arepresentative and sequential arrangement on the basis of product flow paths. The P&ID layout doesnot necessarily reflect physical arrangements. A P&ID is not drawn to scale.Where hydraulic elevations and levels of equipment are important to the process, this informationshall be shown on the P&ID by referring to Elevation (EL) with respect to the Australian Height Datum(AHD).Where multiple P&IDs are required, the layout shall be logical and sequential across the drawingsand the break up between the drawings or sheets shall be based on plant or process areas.This Technical Standard and Standard Drawings 4003-00001-01 and 4003-00001-02 specifynumerous coding systems for use in P&IDs. If coding systems are required for other attributes, theymay be developed on an individual project basis. In this case, the systems must be consistent informat with the specified systems and shall be defined on the drawing where they are used and/or ina master legend for the set of drawings.The code formats specified in this Technical Standard and the codes specified on Standard Drawings4003-00001-01 and 4003-00001-02 are specifically for use on P&IDs but may be used in otherapplications as appropriate (often on a general arrangement drawing showing a P&ID tag referenceon a pipe, valve and/or other equipment for process clarity).Revision 2.0 - 16 December 2015For Official Use OnlyPage 8 of 27Uncontrolled When Printed Or Downloaded

TS 112 - Process and Instrumentation Diagrams (P&ID)SA Water - Technical Standard4.2 Process Flow Designation4.2.1 GeneralThe flow direction of main process streams shall, where possible, be from left to right. Flows shallleave P&IDs at the sides, not at the top or bottom.Existing process streams, pipes and/or equipment shall be shown in a light weight, broken and/ordotted line. New or proposed process streams, pipes and/or equipment shall be shown in a solidheavy-weighted line distinct from the line for the existing process streams, pipes and/or equipment.The distinction between line styles must be such that it is clearly evident on a drawing printed at A3size.Additionally, P&IDs shall show the primary process streams, pipes and/or equipment in a solid heavyweighted line type – clearly identifying the primary process.Process streams leaving or entering drawings or sheets shall have a “process flow tag” at the side ofthe drawing indicating the direction of flow, as well as text describing the source and/or destinationof the stream.4.2.2 Process Flow Tag FormatProcess flow tags shall contain the following information as appropriate: FLUID code or description with source or destination EQUIPMENT Name and Number DRAWING NUMBER of source or destination drawing.Example: Incoming process (service) water from a booster pump on a previous sheet might bedesignated as shown in Error! Not a valid bookmark self-reference. below:Process Water fromBooster Pump XXXXDrawing YYYY-XXXXX-XXFigure 1 - Typical process flow tag format for incoming process flow (left of page)4.3 Piping Designation4.3.1 Piping Designation CodePiping designation shall be in the form: DIAM-FLU-MATL-XXXWhere: DIAM is the pipe size, either nominal or actual FLU is the Fluid Code for the contained fluid as per Standard Drawing 4003-00001-02 MATL is the pipe Material Code as per Standard Drawing 4003-00001-02 XXX is the line number (optional)Example: An effluent pipe of 200 diameter polyethylene on line 006 might be designated as 200-EFFHDPE-006Revision 2.0 - 16 December 2015For Official Use OnlyPage 9 of 27Uncontrolled When Printed Or Downloaded

Any newequipment added to a particular location shall be incremented numerically from the existingequipment in that location.Equipment details shall be vertically aligned to the respective equipment on the P&ID.4.4.2 Equipment Designation CodeEquipment designation shall be in the form: EQPT-LOCN-XXXwhere: EQPT is the equipment or valve title abbreviation which often includes the fluid identifier andmay be project specific LOCN is the location code (letters or numbers) – this refers to the location of the equipmentwithin a treatment plant for example, not a geographic location/township, and is optionaldepending on the size and complexity of the plant XXX is the equipment numberExamples: A process water pump 2 in a chemical dosing area might be designated as PRWP-CHEM-002 A manual ball valve might be designated as HV-010 A process globe valve (pressure sustaining) in a chemical dosing area might be designated asPV-002-009 A compressor at the Happy Valley WTP might be designated as CO-096-300 A chlorinator at the Happy Valley WTP might be designated as CH-096-001Revision 2.0 - 16 December 2015For Official Use OnlyPage 10 of 27Uncontrolled When Printed Or Downloaded

Allchemicals and process fluids are grouped into one of three hazard level categories:Hazard Level B (medium (average) level hazard): very harmful fluids, powders, etc (e.g., typicallyacids pH 2 or alkalis pH 11)Hazard level C (low hazard): harmful fluids or powders, low strength acids or alkalis, combustible,corrosive or high temperature fluidsHazard Level E (negligible hazard): non-harmful fluids or powders, typically all water and wastewaterstreams and normal process airRevision 2.0 - 16 December 2015For Official Use OnlyPage 11 of 27Uncontrolled When Printed Or Downloaded

TS 112 - Process and Instrumentation Diagrams (P&ID)SA Water - Technical Standardspecific sites. At the commencement of design works, designers shall engage with plant operatorsand/or the contract superintendent’s representative to establish if a site has an existing (andestablished) numbering and tagging convention. This rule only applies to work associated with a siteand/or plant that has an established convention and where introduction of a new convention wouldlead to operator and maintenance staff confusion and error.Any established convention identified within the design phase of a new project shall becommunicated back to SA Water Engineering for assessment and confirmation.5Drawing & Drafting RequirementsP&IDs are considered to be Engineering Drawings. They shall be prepared, managed, formatted (i.e.,line types and styles), presented and numbered in accordance with TS95 “Requirements for TechnicalDrawings”.Symbols and representations used on P&IDs shall be as per Standard Drawings 4003-00001-01 and4003-00001-02.Revision 2.0 - 16 December 2015For Official Use OnlyPage 14 of 27Uncontrolled When Printed Or Downloaded
