Valve and Hydrant Assessment

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. Having critical valve intelligence is invaluable in times of crisis, for example during a major water main break, when an immediate shutdown is required to alleviate damage to nearby property. Hydrant condition assessment allows water utilities to establish schedules for repair and maintenance through regular hydrant condition inspection and maintenance projects. Undertaking hydrant assessments ensures critical assets are capable of delivering 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 operability of the critical valve assets, the flow and pressure of fire hydrants, determining estimated remaining life, recommend any maintenance or repairs required.

What is the purpose of Valve Condition Assessment?

Water utilities should develop programs to regularly undertake valve condition assessment and maintenance to assist with improving their organisational knowledge about their valve inventory. Broken, closed, missing or seized valves can have an outsized consequence impact during water main failure events that require emergency shut down. 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 time taken to undertake reactive repair works.
  • Limit the number of customers interruptions during a water main burst or other network outage.
  • Confirm the status of valves and provide this information to a hydraulic model to obtain more accurate insights

What are the benefits of Valve Condition Assessment?

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

  • A full 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 form 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

Why undertake a Hydrant Condition Assessment in your water network?

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

  • Hydrant flow testing
  • Hydrant pressure 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

Reduce workplace injuries with smart, proactive valve condition assessment

Workplace health and safety is the largest 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.

How do we implement a Valve Condition Assessment or Hydrant Condition Assessment project in Australia or New Zealand?

Valve and hydrant condition assessment projects are very beneficial to identify and repair the discrepancies that may exist in enterprise datasets. If you want to improve your water network performance, reduce customer impacts, and increase operational reliability, contact us today to discuss our options for valve and hydrant condition assessment throughout Australia and New Zealand.
