Full title and description
GOST 21.704-2011 — System of design documents for construction. Rules for execution of working documentation of outside networks of water supply and sewerage (Russian: ГОСТ 21.704-2011. Система проектной документации для строительства. Правила выполнения рабочей документации наружных сетей водоснабжения и канализации). Этот межгосударственный стандарт устанавливает требования к составу и оформлению рабочей документации для наружных сетей водоснабжения и канализации.
Abstract
Standard GOST 21.704-2011 specifies the required set of working drawings and documents (plans, longitudinal profiles, specifications, schematic and installation details), rules for graphic representation and content, and conventions to be used when preparing working documentation for external water-supply and sewerage networks for construction projects of various types. It replaces earlier guidance for outside water and sewer networks and harmonizes document presentation within the System of Project Documentation for Construction (SPDS).
General information
- Status: Active; introduced as a межгосударственный (GOST) standard and intended to replace GOST 21.604-82.
- Publication date: Designation year 2011 (GOST 21.704-2011); approved by the Federal Agency for Technical Regulation and Metrology (Rosstandart) by order No. 484‑ст on 11 October 2012 and put into effect 01 May 2013.
- Publisher: Federal Agency for Technical Regulation and Metrology (Rosstandart) / national standards bodies that distribute the official text.
- ICS / categories: Relevant ICS areas commonly associated with this topic include 91.140.60 (water supply systems), 91.140.80 (drainage systems) and 93.030 (external sewage systems). These ICS classes are typically used for standards on water supply and sewerage documentation and design.
- Edition / version: GOST 21.704-2011 (current edition introduced 2011; effective from 01 May 2013 with later editorial amendments published as applicable).
- Number of pages: Approx. 20–22 pages in common published distributions (commercial listings and standards vendors list the PDF/text as ~22 pages).
Scope
The standard applies to preparation of working documentation for outdoor networks of potable water supply and sewerage (gravity and pressure systems) for construction projects of various purposes. It defines the composition of the working set (plans, profiles, details, specifications), required graphic conventions, and essential data to be included so that construction and installation works can be executed and checked.
Key topics and requirements
- Required content of working documentation for external water-supply and sewerage networks (network plans, longitudinal and cross profiles, hydraulic and schematic diagrams, node details, material and product specifications).
- Rules for graphic representation, scale selection, labelling and dimensioning of plans and profiles.
- Mandatory information to include: pipe types and diameters, slopes, elevations, invert levels, manholes and inspection chambers, fittings, valves, supports, protective measures and connection details.
- Specification and tabulation requirements for equipment, fittings, materials and construction units (format and required fields for lists and specifications).
- Examples and recommended formats for profiles and fragments of plans (informative appendices provide illustrative examples of profile execution and schematic diagrams).
Typical use and users
Primary users are civil and water‑supply engineers, design organizations, CAD technicians preparing working documentation, contractors executing external networks, municipal infrastructure planners and reviewers, and regulatory authorities responsible for accepting design documentation. The standard is used during design development, tender documentation preparation and construction drawing issuance.
Related standards
Commonly referenced and related documents include earlier GOST 21.604-82 (which GOST 21.704-2011 replaces), other SPDS/GOST documents on general project and working documentation (for example GOST 21.101—system requirements, GOST R 21.1101—basic requirements to design and working documentation), and national codes for water‑supply and sewerage engineering and construction rules (relevant SNiP / SP documents and technical regulations).

FAQ
Q: What is this standard?
A: GOST 21.704-2011 is a межгосударственный (GOST) standard providing rules for preparing working documentation for outside water‑supply and sewerage networks within the System of Project Documentation for Construction (SPDS).
Q: What does it cover?
A: It covers the required composition and format of working drawings and associated documents (plans, profiles, diagrams, specifications), graphic conventions and essential data needed to construct and install external potable water and sewerage systems.
Q: Who typically uses it?
A: Design organizations (engineers and CAD specialists), contractors, municipal infrastructure planners and reviewers, and inspection authorities use the standard to prepare, check and accept working documentation for external networks.
Q: Is it current or superseded?
A: As of its approval and entry into force, GOST 21.704-2011 replaced GOST 21.604-82. The 21.704-2011 edition has been published and remains the applicable GOST for working documentation of external water‑supply and sewerage networks, subject to later amendments and editorial updates published by the standards body. Users should check the official standards register or legal/standards systems for the most recent amendment status before use.
Q: Is it part of a series?
A: Yes — it is part of the broader SPDS / GOST 21 series (System of project documentation for construction) that contains multiple standards governing different parts of project and working documentation (architectural, structural, engineering systems, specifications, and drawing rules).
Q: What are the key keywords?
A: Water supply; sewerage; external networks; working documentation; network plan; longitudinal profile; specifications; SPDS; construction documentation.
