The CP 48:2005 Code of Practice for Water Services is a comprehensive guideline established by the Singapore Standards Council. It serves as a predecessor to SS 636:2018 and provides detailed instructions and best practices for the design, installation, testing, and maintenance of water services within buildings and premises. Below are the key aspects of the CP 48:2005 Code of Practice:
Objectives of CP 48:2005
- Safety: To ensure the safety and hygiene of water supply systems, preventing contamination and health risks.
- Reliability: To establish standards ensuring the reliability and consistent performance of water services.
- Efficiency: To promote the efficient and sustainable use of water resources.
Scope
The CP 48:2005 covers:
- Design and Installation: Guidelines for the proper design and installation of potable water systems, addressing aspects such as pipe sizing, material selection, and installation practices.
- Testing and Commissioning: Procedures for thorough testing and commissioning to verify that water systems meet the required standards before being put into operation.
- Maintenance: Recommendations for regular maintenance and inspection to ensure the continued compliance and performance of water supply systems.
Key Sections

Compliance and Enforcement
Compliance with CP 48:2005 is mandatory for all new water service installations and significant modifications to existing systems in Singapore. Regulatory authorities enforce adherence to the standards, and non-compliance can result in penalties and mandatory corrective measures.
Implementation
Professionals such as engineers, plumbers, and contractors involved in water service design, installation, and maintenance must be thoroughly acquainted with CP 48:2005 to ensure their work adheres to the established standards.
Benefits
- Health and Safety: Ensures that water supply systems are safe, hygienic, and free from contamination risks.
- Quality Assurance: Provides a standardized benchmark for the quality and performance of water service installations.
- Sustainability: Encourages efficient use and management of water resources, contributing to environmental sustainability.
Transition to SS 636:2018
With the introduction of SS 636:2018, CP 48:2005 has been succeeded, but its foundational principles continue to influence modern water service practices. Professionals should refer to SS 636:2018 for current standards while recognizing the historical importance of CP 48:2005 in shaping water service guidelines.
For detailed guidance, professionals should consult the full CP 48:2005 document available from the Singapore Standards Council or authorized distributors.
