Hydraulic Systems Testing

Including Pressure Testing of Water Mains and Flow Testing of Sewer Mains Hydraulic systems are the backbone of essential infrastructure—from water supply to wastewater management. Keeping them running efficiently isn’t just important—it’s critical.

At Precision Civil and Hydraulic Engineering, we offer expert testing services to ensure the integrity and performance of your systems. Our pressure testing of water mains and flow testing of sewer mains help detect faults early, validate system strength, and support long-term reliability.

With integrated data logging, we deliver accurate, real-time insights that enhance decision-making and ensure prompt issue resolution. Whether for new installations or routine maintenance, our testing services are designed to keep your infrastructure safe, compliant, and running at peak performance.

Explore our specialised services below and see how we help safeguard the systems your projects depend on

Pressure Testing of Water Mains

  • Leak Detection: Identify and locate leaks that could lead to water loss or system contamination.
  • Pressure Resistance: Verify that water mains can safely withstand operational pressures without risk of failure.
  • Regulatory Compliance: Confirm that systems meet all relevant industry standards and specifications.

Our pressure testing process involves filling water mains, sealing the system, and applying controlled pressure to detect any weaknesses or potential faults.

Flow Testing of Sewer Mains

  • Flow Measurement: Assess flow rates to ensure sewer mains can manage peak load conditions.
  • Blockage Detection: Identify obstructions that could restrict flow and cause system backups.
  • System Efficiency: Evaluate the overall performance and condition of sewer infrastructure.

Flow testing introduces a measured quantity of water into the sewer main and records flow rates to ensure the system operates at optimal capacity.

Data Logging Integration

  • Continuous Monitoring: Capture real-time data over extended periods for a thorough performance assessment.
  • Accurate Recordkeeping: Maintain precise logs of pressure and flow measurements for compliance and future reference.
  • Enhanced Diagnostics: Identify trends, anomalies, and early warning signs of potential system issues.

Our data logging technology provides high-accuracy insights to support proactive maintenance, repairs, and system optimisation.
