Experts in Valve and Fire Hydrant Testing

Valve condition assessment involves the inspection, operation and evaluation of the mechanical condition and operational reliability of critical water network valves throughout a water supply system. Critical valve intelligence is invaluable in times of crisis: For example, during a major water main break when an immediate shutdown is required to reduce damage to nearby property.

Fire hydrant testing allows water utilities to establish hydrant servicing and repair schedules through regular condition inspection and maintenance projects. Undertaking hydrant assessments ensure critical assets can deliver water at required pressures and flow rates.

Using best-in-class valve condition assessment and hydrant inspection technologies and methodologies, Aqua Analytics can provide comprehensive reports detailing the function of the critical valve assets, the flow and pressure of fire hydrants, determining estimated remaining life, and recommending any required maintenance or repairs so the assets are operable when they are required.

Valve Condition Assessment

When it comes to critical components within your water network, you don’t want to take any chances. Our valve condition assessments utilise innovative technology and expert technicians to obtain actionable insight to reduce future disruptions or critical incidents.

Technicians will conduct any maintenance or repairs necessary throughout the service and collect critical data to inform future asset management decisions. All information is captured spatially in our customised GIS reporting tool, and data can be provided back to clients in a range of formats for easy ingestion into Enterprise systems.

With over three decades of industry experience, we have developed comprehensive water network management methodologies to deliver precise, effective results that improve operational efficiency including water loss management and active leak detection.

The Value of Valve Assessment

Routine maintenance, assessment, and testing are vital to the ongoing resilience of any water network. With ongoing valve condition assessments, organisations improve their knowledge of valve inventory and the maintenance requirements. Additionally, these assessments reduce the risk of injuries to workers who operate seized valves and improve the accessibility and condition of critical valves.

The increased knowledge of the network and confidence in its operation reduces the consequence of a water main failure since valves can stem the flow of water more readily. Improved understanding of the water network enhances the control of water flow within the network, and ongoing assessment and servicing increase the working life of the valves.

At Aqua Analytics, we provide tailored solutions for valve condition assessment and on either long-term and short-term projects – or while we are undertaking other works such as active leak detection. Our range of services and expert technicians utilise proven methods and the latest network assessment technology to provide results that are second to none.

Our approach to assessment and testing ensures improved operations and reliability for the assets within your water network, improved safety for workers, and enhanced asset management outcomes knowing your critical assets will work as intended when required. For more information on how we can develop a valve condition assessment program, please contact us today.

What Is the purpose of valve condition assessment?

Water utilities should develop programs to regularly undertake valve condition assessment and maintenance to improve organisational knowledge about their valve inventory.

Broken, closed, missing, or seized valves can significantly impact water main failure events that require emergency shutdown. Better water network knowledge and asset intelligence are critical for the management of these disruptive events. Other reasons why a valve condition assessment should be undertaken are to:

  • Reduce the risk of injuries to field staff who operate seized valves.
  • Increase confidence that critical valves are accessible and in good working condition, reducing the time to undertake reactive repair works.
  • Limit the number of customers interruptions during a water main burst or other network outages.
  • Confirm the status of valves and provide this information to a hydraulic model to obtain more accurate insights.

Understanding the condition of your critical valves enhances your ability to control water flow within the distribution system effectively. It also allows you to extend valve life and quickly locate valves in the field when operation is required. Valve condition assessment enables:

  • A complete inventory of distribution system valves and mapped with high accuracy using our specialist GPS-enabled field equipment
  • More efficient future shut down of water mains during burst events or reactive maintenance minimising the customer impact and damage to nearby property
  • More insight into future CAPEX and OPEX requirements to improve valve operations and network reliability
  • Greater confidence in Consequence of Failure (CoF) and Likelihood of Failure (LoF) studies
  • Locating buried valves and improving access by removing debris from valve spindles
  • Exercising of seized valves maintaining asset health.
  • Identification of broken valves
  • Identification of closed valves and determination of clockwise/anti-clockwise closing orientation
  • Correctly identifying valve type (for example: scour valves that may be incorrectly shown as isolation valves)
  • Extension of asset life by exercising of valves until the torque required to operate is reduced

We use a range of specialised equipment to undertake our valve condition assessment and fire flow testing works.

Using fire hydrant testing to understand the condition of your hydrants allows minimal interruption when they are required at critical times. It is also important that in times of need, these critical water assets can deliver the required pressures and flow rates to local regulations and standards. We utilise smart technologies to undertake hydrant inspections and assessments, leveraging the power of GIS integration solutions such as ESRI ArcGIS and Trimble Water. Other aspects of our hydrant inspections are:

  • Fire hydrant testing
  • Hydrant pressure and flow testing
  • Minor maintenance activities such as painting, removal of sediment, installation of marker pegs/reflective cats eyes
  • Major maintenance activities such as repair or removal of yokes, spring ball, riser or tee (including developing shutdown plans or undertaking customer notifications)
  • Water mains cleaning
  • Capturing photographs and GPS data for integration into Asset Management Systems
  • Locating missing or covered hydrants
  • A full hydrant asset inventory using Trimble Unity or ArcGIS

We can also provide active leak detection, pipeline condition assessment or water loss management solutions.

Workplace health and safety is the biggest priority of most water utilities in Australia and New Zealand. Undertaking a valve condition assessment program enhances the safety of your field teams since the mechanical operation of valves will significantly reduce the risk of valve operator injuries. Improve the safety of your teams by implementing a structured valve condition assessment program.

Valve condition assessment and hydrant flow testing projects are very beneficial for identifying and repairing discrepancies in enterprise datasets.
