Full title and description

SP 31.13330.2012 — "Water supply. External networks and structures" (Свод правил. Водоснабжение. Наружные сети и сооружения). Actualized edition of SNiP 2.04.02-84* covering design, layout, construction and operation requirements for external water-supply networks, mains, intake and treatment facilities, pumping and storage structures, and associated site works. The edition includes Amendments No. 1–5.

Abstract

SP 31.13330.2012 provides regulatory requirements and recommended practices for planning, hydraulic calculation, structural design, construction, installation and maintenance of external water-supply systems and related facilities. It consolidates and updates previous SNiP rules into a single regulatory document, establishes classification of water sources and treatment technologies, sets criteria for reliability and safety, and includes normative provisions for protection zones, material selection, trenching and backfill, hydraulic testing and commissioning.

Scope

This set of rules applies to the design, construction, reconstruction and technical operation of external potable and utility water-supply systems: surface and groundwater intakes, transmission mains (pressure and gravity), distribution networks, pumping stations, reservoirs and water-treatment units located outside buildings. It covers planning and engineering requirements for new works and for major reconstruction projects; it is intended for projects up to typical municipal/regional scales and cross-references other building codes and environmental regulations. It does not replace specific industrial process water standards or special-purpose high-capacity systems beyond its stated classes.

Key topics and requirements

• Classification of water sources and requirements for intake design and protection zones.
• Hydraulic calculation methods for mains, selection of pipe diameters and pump systems, and criteria for reliability and redundancy.
• Design and construction rules for trenches, bedding, backfill, supports, anchors and anti-corrosion protection of pipelines.
• Design of reservoirs, tanks and water towers including foundations, waterproofing and access arrangements.
• Water-treatment and disinfection requirements for potable water; classification of treatment technologies and performance criteria.
• Requirements for fittings, valves, hydrants, air valves and access chambers; clearances and installation details.
• Testing, commissioning, maintenance regimes, inspection intervals and procedures for hydraulic and sanitary safety.
• Reliability assessment, failure-rate considerations and ranking of destabilizing factors for system resilience.
• Environmental and sanitary protection measures, including erosion control, site drainage and protection of groundwater.

Typical use and users

Engineers, designers and technical specialists in municipal and industrial water-supply design use SP 31.13330.2012 as a primary normative reference for external network projects. Typical users include consulting design bureaus, municipal utilities (water companies), construction contractors, inspection authorities and project reviewers involved in civil infrastructure, urban planning and utility rehabilitation. It is also used in education and professional training for water-supply engineering.

FAQ

Q: What is this standard?

A: SP 31.13330.2012 is the Russian "Svod pravil" (set of rules) titled "Water supply. External networks and structures" — an actualized edition of SNiP 2.04.02-84* that sets design, construction and operation requirements for external water-supply systems.

Q: What does it cover?

A: It covers classification of water sources, intake and treatment facilities, hydraulic design of mains and networks, structural and installation requirements for pipelines and associated structures, protective measures, commissioning and maintenance procedures, and reliability criteria for municipal and similar water-supply systems.

Q: Who typically uses it?

A: Municipal and industrial water engineers, design organizations, construction contractors, utility operators, regulatory inspectors and reviewers use the document when designing, building, commissioning or operating external water-supply networks.

Q: Is it current or superseded?

A: SP 31.13330.2012 has been superseded by a later edition (SP 31.13330.2021). SP 31.13330.2012 was approved at the end of 2011, entered into force on 1 January 2013 and was updated by a series of amendments; for current regulatory requirements users should refer to the 2021 edition and any subsequent amendments or revisions issued by the competent authority.

Q: Is it part of a series?

A: Yes. SP 31.13330.2012 is part of the national "SP" (Svod pravil) series of construction rules that update and consolidate SNiP regulations; it cross-references other SP/SNiP documents for internal water supply, sewerage, foundations and related civil engineering topics.

Q: What are the key keywords?

A: Key keywords are: water supply, external networks, pipelines, water mains, intake, pumping station, reservoir, water treatment, trenching, hydraulic design, corrosion protection, commissioning, SNiP, SP 31.13330.2012.
