KMK 2.04.01-98 PDF

Full title and description

KMK 2.04.01-98 — Внутренний водопровод и канализация зданий (Internal water supply and sewerage of buildings). Technical norms for design of internal cold and hot water supply, sanitary and storm drainage systems; published with Amendment No.1 and Amendment No.2.

Abstract

This national construction norm (KMK) sets out requirements and recommended practices for planning, hydraulic calculation, material selection, routing and installation of internal potable-water supply, domestic and industrial sewage, roof/storm drainage and associated sanitary fixtures in residential, public and industrial buildings. It includes provisions for venting of sewerage stacks, protection against freezing and corrosion, metering and local treatment of problematic industrial effluents; the document was later superseded by a 2022 ShNK update.

General information

• Status: Superseded — replaced by ShNK 2.04.01-22 (internal water supply and wastewater disposal).
• Publication date: 1998 (original adoption year; amended with Amendment No.1 and No.2).
• Publisher: Part of the KMK set of construction norms and rules of the Republic of Uzbekistan (national construction/engineering norms issued under the country’s construction and urban-planning authorities).
• ICS / categories: Installations in buildings — water supply systems (91.140.60), sanitary installations (91.140.70) and drainage systems (91.140.80).
• Edition / version: Original KMK 2.04.01-98 (1998) with Amendments No.1 and No.2; later incorporated and updated in ShNK 2.04.01-22.
• Number of pages: Approximately 84 pages (electronic PDF/word versions available from technical-document vendors).

Scope

Applies to the design of new and reconstructed internal potable water supply (cold and hot), domestic and industrial wastewater systems, internal stormwater downspouts and drainage within buildings, and their connections to external networks. The norm covers layout, sizing, ventilation and discharge arrangements, selection of materials and protective measures (insulation, anti-corrosion, frost protection), plus provisions for local treatment of certain industrial effluents before discharge to the public sewer.

Key topics and requirements

• Design principles for internal cold and hot water supply systems — routing, zoning, hydraulic calculation and pressure considerations.
• Requirements for sanitary fixtures, fixture-unit loads and internal layout to ensure proper drainage and maintenance access.
• Drainage and stormwater disposal: roof drainage, internal downspouts, sizing and discharge to external networks.
• Venting of sewage stacks and rules for exhaust/vent stack termination above roof level.
• Material selection, connections, sleeves where pipes pass through structures, and corrosion / freeze protection measures.
• Requirements for local pre-treatment or separation of industrial wastes (oils, greases, acids, hazardous discharges) before release to municipal sewers.
• Provision for metering (water meters) and fire-water supply arrangements (hydrants and fire-fighting water requirements referenced in later related ShNK/KMK documents).
• Compliance, testing and inspection expectations during construction and commissioning; references to applicable hygiene and drinking-water quality requirements.

Typical use and users

Used by plumbing and sanitary engineers, building services designers, architects, construction contractors, municipal permitting and inspection authorities, and facilities managers working on residential, public and industrial building projects in Uzbekistan and neighbouring regions where KMK norms are referenced. Practitioners consult KMK 2.04.01-98 for design rules on internal water and sewer systems, then apply the later ShNK 2.04.01-22 update where required.

Related standards

Commonly referenced documents in design packages include KMK/ShNK series items such as ShNK 2.04.01-22 (replacement), KMK 2.04.02 (external water supply and networks), KMK 2.03.11 (protection of structures from corrosion) and national hygiene/drinking-water standards (e.g., O’z DSt 950 series). The KMK/ShNK framework and specific cross-references are listed in normative annexes.

FAQ

Q: What is this standard?

A: KMK 2.04.01-98 is a Republic of Uzbekistan construction norm titled “Internal water supply and sewerage of buildings” that provides technical rules for design and installation of internal potable-water, sanitary- and storm-drainage systems (originally published in 1998, with subsequent amendments).

Q: What does it cover?

A: It covers hydraulic design, layout and routing of cold and hot water supply, sanitary fixtures and internal sewerage, roof and storm drainage, venting of sewerage stacks, material and installation requirements, protections (insulation, corrosion), metering and provisions for treating certain industrial wastes before discharge.

Q: Who typically uses it?

A: Plumbing/sanitary engineers, building services designers, architects, contractors, regulators and facilities managers in projects governed by Uzbek construction norms. It is commonly used alongside other KMK/ShNK documents in project specifications.

Q: Is it current or superseded?

A: Superseded — the KMK 2.04.01-98 text has been updated and replaced by ShNK 2.04.01-22 (the 2022 ShNK revision for internal water supply and wastewater disposal). Designers should consult ShNK 2.04.01-22 for the latest mandatory requirements and use KMK 2.04.01-98 only for historical reference where applicable.

Q: Is it part of a series?

A: Yes — it is part of the KMK family of construction norms and rules used in Uzbekistan (KMK covers numerous design topics across building services, structural and site works), and it links to other KMK/ShNK items (external water supply, heating/ventilation, fire safety, corrosion protection, etc.).

Q: What are the key keywords?
