Full title and description

KMK 3.05.04-97 — Outdoor water supply and sewerage networks and structures (Russian: КМК 3.05.04-97 — Наружные сети и сооружения водоснабжения и канализации). Technical guidance describing requirements for design, construction, testing and acceptance of external water supply and sewerage systems and associated civil structures.

Abstract

KMK 3.05.04-97 is a national technical document that sets out recommended rules and procedures for planning, installation, commissioning and acceptance of outdoor water supply and sanitary sewerage networks and their associated structures (pipelines, manholes, pumping stations, chambers, connections and basic ancillary works). It provides practical requirements for materials, jointing, trenching and backfilling, hydraulics and basic quality control and acceptance testing used by designers, contractors and inspectors.

Scope

The document covers external (outdoor) potable water supply and sanitary sewerage networks and auxiliary structures for settlements and civil works. It addresses organization of works, technical requirements for pipelines and fittings, site preparation and trenching, installation of manholes and chambers, pumping stations basics, protection against corrosion and frost, test procedures, and rules for acceptance of completed works. It is intended for project and construction stages (design, execution, inspection, commissioning).

Key topics and requirements

• Definitions and classification of outdoor water supply and sewerage elements (pipelines, manholes, chambers, pumping stations).
• Design and routing principles: hydraulic gradients, cover depths, separation of potable and wastewater lines, allowances for future connections.
• Material selection and quality: pipes, joints, seals, valves and accessories; requirements for durability and corrosion protection.
• Trench excavation, bedding and backfill requirements, compaction and restoration of surface finishes.
• Installation procedures for manholes, chambers, inlets and outlets; access and ventilation considerations.
• Pumping station siting and basic mechanical/electrical installation rules (layout, redundancy, accessibility).
• Testing, commissioning and acceptance tests: hydraulic tightness, pressure tests, inspection regimes and defect rectification.
• Documentation and marking: required as-built records, drawings, certificates and handover documentation for utilities.
• Health, safety and environmental precautions during construction and operation (site safety, temporary drainage, pollution control).

Typical use and users

Used by civil and hydraulic engineers, municipal utility designers, site contractors, construction supervisors, quality control and inspection teams, local authorities and asset owners responsible for design, construction and acceptance of external water supply and sewerage infrastructure. Also referenced by planners and procurement teams preparing contract specifications and technical briefs.

FAQ

Q: What is this standard?

A: KMK 3.05.04-97 is a national technical code for outdoor water supply and sewerage networks and associated structures (originally issued in 1997). It provides practical requirements for design, construction, testing and acceptance of external water and sewer infrastructure.

Q: What does it cover?

A: It covers planning and execution of external potable water and sanitary sewer systems — including pipelines, joints, manholes/chambers, basic pumping-station requirements, trenching and backfilling, material selection, testing and acceptance procedures.

Q: Who typically uses it?

A: Civil and hydraulic engineers, contractors and construction supervisors, municipal utilities, inspectors and local authorities involved in design, construction and commissioning of water and sewer networks.

Q: Is it current or superseded?

A: KMK 3.05.04-97 has been superseded. It is listed as replaced by the QR-series document QR 05.04-23 (replacement issued in the 2023 QR update). For current regulatory requirements and mandatory rules, consult the replacement QR 05.04-23 and the relevant national construction authority guidance.

Q: Is it part of a series?

A: Yes — KMK 3.05.04-97 is part of the KMK (construction-methodical) series covering construction works and equipment (the 3.05 group covers building services and engineering systems). The KMK series has been progressively revised and many items replaced by SHNK or QR series documents.

Q: What are the key keywords?
