Hydrant Condition Assessment and Maintenance

A properly managed hydrant assessment program helps to establish schedules for repair and replacement through regular hydrant maintenance through which a utility can determine the useful life of a fire hydrant and schedule replacement well in advance of predictable hydrant failure. For public health and firefighting operations, the hydrants should be tested on a regular basis to ensure that they are capable of delivering water at required pressures and flow rates. The distribution systems are constantly impacted by improvements, deterioration, changes in usage and even maintenance activities.
HUSA hydrant test procedures are conducted in accordance with AWWA Fire Flow Testing and ISO procedures. The tests include detailed determination of both the flow and test hydrants, measuring of static and residual test pressures, conducting sufficient hydrant flow to adequately stress the system and the necessary analyses to determine fire-flow capacities. HUSA can conduct hydrant tests utilizing multiple flow hydrants under varying system boundary conditions to support engineering facility plan models and identify operational conditions.

Hydromax USA’s system-wide condition assessment and maintenance programs can provide:

  • Complete inventory of distribution system hydrants mapped with sub-foot accuracy.
  • Assurance of system hydrant and isolation valve operability, flow, and accessibility.

Active remediation of system hydrants to restore functionality including:

  • Minor repairs
  • Extensions
  • Upper Barrel Repairs
  • Lower Barrel Repairs
  • Provides information on the current operating state of distribution system hydrants.
  • Analysis of capital and O&M needs for improved planning and system performance.
    The information provides the foundation for COF/LOF failure impact studies and remediation prioritization planning.

Our Infrastructure Condition Assessment Programs include:

  • Pre-program consulting on Hydromax USA geospatial solutions
  • Review of current client water data model and CMMS system.
  • Access to Hydromax USA – Project Operations Dashboard, providing near real time project results and tracking.
  • Locate and access each fire hydrant
  • Field locating, accessing, and exercise isolation valve
  • Check hydrant nozzle height for correct ground clearance.
  • Identify make, model, and year of hydrant manufacture.
  • Identify hydrant main valve and hose/pumper nozzle sizes.
  • Lubricate operating nut and all nozzle outlets with F.D.A. approved lubricant.
  • Open hydrant with nozzle caps in place to check for seal leakage.
  • Verify hydrant main valve completely closes.
  • Flow hydrant, record working pressure, calculate flow rate, record static pressure.
  • Leak sounding at each hydrant location.
  • Tighten hydrant nozzle caps slightly more than hand tight
  • Clean and paint hydrant in utility specified color.
  • Analysis of hydrant and isolation valve assessment results and creation of program evaluation report.
  • Scheduled ESRI compliant program data deliverables.
  • Integration of work order data into most major CMMS systems.
