KMK 2.04.02-97 PDF

Full title and description

KMK 2.04.02-97 — "Water supply. Exterior networks and structures." National construction norm (KMK) covering design, layout and technical requirements for external (municipal and industrial) water-supply networks and associated structures; issued with Amendment No.1 and Amendment No.2.

Abstract

Technical code that establishes requirements for planning and engineering of centralized permanent external water-supply systems for settlements and economic facilities, including water intakes, transmission mains, pumping stations, reservoirs, treatment units (where applicable), hydraulic calculations, material and installation rules, and provisions for fire‑fighting supply and sanitary protection zones. (This edition has since been superseded by a 2019 revision.)

• Publication date: 1997 (document number ends in -97 indicating the 1997 edition).
• Publisher: National construction technical regulator / State Committee for Architecture and Construction (KMK series — Uzbek national construction norms).
• ICS / categories: Construction / Water supply; commonly associated ICS codes for water-supply practice (e.g., 91.140.60 — water supply systems and external networks).
• Edition / version: Original KMK 2.04.02-97 with Amendment No.1 and Amendment No.2 (1997 edition).
• Number of pages: 156 (PDF/electronic edition as listed in document catalogues).

Scope

Applies to the design and reconstruction of centralized, permanent external water-supply networks and structures serving towns, settlements and national‑economy facilities. It covers site selection and protection of water intakes, hydraulic design of mains and collectors, pump and reservoir design, fire‑fighting supply requirements, sanitary protection zones, routing and coordination with other utilities, and basic material and installation requirements for pipelines and fittings. The standard is intended for use in project documentation and construction practice within the national regulatory framework.

Key topics and requirements

• Design principles for surface and groundwater intake structures and protection of source areas.
• Hydraulic calculation methods for transmission mains, distribution branches and pressure regimes.
• Requirements for pumping stations, selection of pumps, lay‑out and redundancy for reliability.
• Storage reservoirs (elevated and ground-level): capacities, filling/draining regimes and structural provisions.
• Pipe materials and joints (selection criteria, corrosion protection, trenching and backfill requirements).
• Fire‑fighting supply design — minimum flow/pressure criteria for external fire protection systems.
• Sanitary protection zones, wastewater exclusion and interface with treatment/discharge provisions.
• Coordination of external networks with urban planning, other utilities and road crossings.
• Rules for testing, commissioning and handover of external water‑supply systems.

Typical use and users

Primary users are civil and water‑supply engineers, urban and infrastructure planners, municipal water and wastewater utilities (vodokanal/uzsuvtaminot), design organizations, construction contractors, technical supervisors and regulatory inspectors working on design, construction, reconstruction and acceptance of external water‑supply systems in Uzbekistan (and as a reference for regional projects).

FAQ

Q: What is this standard?

A: KMK 2.04.02-97 is a national construction norm (KMK) titled "Water supply. Exterior networks and structures" that sets technical requirements for the design and construction of external water‑supply systems.

Q: What does it cover?

A: It covers intake structures, transmission mains, pumping stations, storage reservoirs, hydraulic calculations, materials and installation rules, fire‑fighting supply provisions and sanitary protection measures for centralized external water‑supply systems.

Q: Who typically uses it?

A: Design institutes, municipal and regional water utilities, construction contractors, project managers, technical supervisors and regulators involved in external water‑supply projects.

Q: Is it current or superseded?

A: The KMK 2.04.02-97 edition has been superseded — the active replacement is KMK 2.04.02-19 (the 2019 revision), which contains updated and expanded requirements; users performing new designs should follow the 2019 edition unless a project specifically references the 1997 text.
