Why Is Contamination Prevention Important in Water Main Repairs?

• Contaminants such as soil, bacteria, and chemicals can enter the water supply if pipes are not properly cleaned, disinfected, and sealed.
• Improper handling of potable water pipes can result in public health risks and legal non-compliance.
• Employers must follow HSE workplace safety guidelines and Water UK’s Contaminated Land Guidance for Utility Companies.
• Using approved materials, protective barriers, and sterilisation techniques ensures safe repairs and prevents waterborne hazards.

Best Practices for Water Main Repairs and Contamination Prevention

• Isolate and Drain the Affected Section – Prevent contaminated water from entering the main supply.

• Follow Proper Excavation Procedures – Keep excavated materials away from open pipes to avoid contamination.
