Full title and description

STB PD ISO TR 7035-2-2024 — Design and asset management of DIP for water application — Part 2: Design, installation and operation. This document provides guidance on good practices for the design, installation, commissioning, operation and rehabilitation of ductile iron pipeline (DIP) systems used in water supply networks; it is published as ISO/TR 7035-2:2024 and is also found listed by some national/reseller catalogues under the STB PD designation.

Abstract

The objective of ISO/TR 7035-2:2024 is to assist designers, engineering offices, water utilities, contractors and project owners with practical guidance for design, installation and operation of ductile iron pipe (DIP) water-supply systems, including new systems and rehabilitation/renovation of existing mains. The report cross-references product and test standards (materials, coatings, joints and site testing) and is intended to complement ISO/TR 7035-1 (asset management).

Scope

ISO/TR 7035-2:2024 covers practical recommendations and good-practice guidance for the full design-to-operation lifecycle of buried and exposed ductile iron pipeline systems for water supply: planning and hydraulic design considerations, pipe bedding and backfill, jointing and restraint, corrosion protection (linings and external coatings), site installation and compaction, pressure testing and commissioning, maintenance and rehabilitation options. It is informative (technical report) and refers users to normative product and test standards for specific material, dimensional and testing requirements.

Key topics and requirements

• Lifecycle guidance for DIP systems: design choices that affect operation, maintenance and asset life.
• Site installation practices: trenching, bedding, backfill, compaction and support to ensure structural performance and longevity.
• Jointing and restraint options: push-on, mechanical and restrained joints; selection and testing considerations.
• Corrosion protection: internal linings (cement mortar) and external coatings/zinc layers, and selection for environmental conditions.
• Hydraulic and structural design considerations: pressure classes, wall thickness classes and compatibility with fittings.
• Commissioning and site testing: pressure testing, leakage checks and verification procedures prior to placing into service.
• Rehabilitation and asset-management links: guidance for renewal strategies and references to asset-management material in ISO/TR 7035-1.

Typical use and users

Primary users are water utility engineers, pipeline designers, consulting engineering firms, construction contractors, asset managers and procurement/specification authors. Regulators, inspection bodies and training organisations may use the report for guidance and to inform local technical specifications and tender documents.

Related standards

ISO/TR 7035-2 is intended to be used alongside product and test standards for ductile iron pipelines, notably ISO 2531 (ductile iron pipes, fittings, accessories and their joints for water applications) and relevant ISO standards for linings and coatings. It also complements ISO/TR 7035-1 (Part 1 — asset management), which is being developed as the companion asset-management document.

FAQ

Q: What is this standard?

A: ISO/TR 7035-2:2024 is a Technical Report giving practical guidance on the design, installation and operation of ductile iron pipeline systems used for water supply (published as Part 2 of the ISO/TR 7035 series).

Q: What does it cover?

A: It covers good-practice recommendations across the lifecycle of DIP systems: planning and hydraulic design, trenching and bedding, jointing and restraint, corrosion protection (linings/coatings), commissioning tests, and options for rehabilitation and maintenance. It is informative and points to normative product and test standards for detailed specifications.

Q: Who typically uses it?

A: Designers, consulting and municipal engineering offices, water companies and pipeline contractors, asset managers, and procurement/specification writers who need practical installation and operational guidance for ductile iron water mains.

Q: Is it current or superseded?

A: This Technical Report was published in 2024 (Edition 1) and is current; users should check ISO and their national standards body for any later revisions or national adoptions.

Q: Is it part of a series?

A: Yes — it is Part 2 of an ISO/TR series on design and asset management of DIP for water application; Part 1 addresses asset management (ISO/AWI TR 7035-1, currently listed as a companion work item).

Q: What are the key keywords?
