Valve Diagnosis and Analysis Program on Water Distribution Systems Print E-mail
InfraResto Corp has developed a unique diagnosis and analysis program to maintain the effective operation and maintenance management of the watermain valves in your water distribution system.

Benefits of Valve Diagnosis and Analysis Program Provided by InfraResto Corp

  • Increases knowledge of your systemís configuration and performance due to closed or partially closed valves.
  • Ensures continued valve operation during emergency conditions.
  • Facilitates water shut down. Faster isolation of main breaks due to accurate valve location schematics and free-turning valves.
  • Identifies deficiencies for repair.
  • Protection of investment through the reduction of premature valve seizure and deterioration caused by sediment and corrosion building-up. During a watermain break, the strength of water can create considerable damage to infrastructure such as watermain and sewer bedding, paving, curbs, sidewalks and other site furniture including landscaping, retaining walls, erosion problems and liabilities for safety to the public.
  • Maximum system performance is ensured if valves are fully opened.
  • During Unidirectional Flushing, valves should be operational to control the direction of water flow and allow isolation of sectors with dirty water; hence ensuring flushing with clean water at all times.
  • Improves water quality.
  • Prevents water interruptions to tenantsí sectors during breaks.
  • Determines size of valve, size of pipe. 

Our Technicians will Perform the Following:

  • Visual inspection of interior and exterior of valve boxes and chambers
  • Verify valve condition and accessibility
  • Manipulate valve to ensure proper operation
  • Verify accumulation of water and sediment in valve box or chamber
  • Identify component type
  • Verify water tightness
  • Detection of possible leak with acoustical amplifier
  • Maximum torque applied
  • Manual manipulation of valve and optional hydraulic manipulation to reduce breakage of seized valves
  • Identify position of valve
  • Supply of computerized report including:
  • statistics
  • Listing of reverse operating valves
  • Remarks and recommendations
  • Recommendations for correcting deficiencies
  • Record sheet of each valve characteristics
  • Plan of water distribution layout based on clientsí utility drawing and field measurements
