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. If you want to improve your water network performance, reduce customer impacts, and increase operational reliability, contact us today to discuss our valve and hydrant condition assessment options throughout Australia and New Zealand.
