Hydraulic and water quality surveys

Hydraulic and water quality information sensor

A new type of sensor that offers unprecedented compactness and energy-saving performance! Not only that, it is smaller (approx. 45%–60%) and provides more efficient electric power consumption (approx. 75%) than conventional models! Using fire hydrants and air valves, this sensor can simultaneously measure and record six different types of hydraulic and water quality data.
Installing multiple sensor units enables you to analyze various types of hydraulic and water quality information, such as the water flow conditions and water quality changes within a specific section of the water distribution network. The results can then be used to create basic information materials for distribution network analysis, measure the effectiveness of maintenance operations, and so on.

Advantages

  • Allows the measurement and recording of multiple items (water pressure, flow rate, flow direction, residual chlorine, electrical conductivity, and water temperature)
  • Enables measurements to be taken for extended periods (10 consecutive days) with no interruption to supply
  • A portable model that eliminates the need for excavation or pipe-cutting work
  • Watertight structure (equivalent to IP68)
  • High reliability ensured

*This product has been jointly developed by TSS Tokyo Water Co., Ltd. and Hitachi High-Tech Solutions Corporation.

Internal washing of distribution pipes

Internal washing method for TS distribution pipes

This method offers an effective means of removing foreign matter (e.g., deteriorated seal coating) that has adhered to the inside of the distribution pipes.
A cleaning head is inserted from the fire hydrant T-tube, without any need for excavation or pipe-cutting, to remove foreign matter that has adhered to or accumulated on the inside of a distribution pipe. If foreign matter cannot be removed from the inside of the pipes by drainage washing, this method is an effective alternative as it allows the pipes to be cleaned by jet-spraying high-pressure water from the cleaning head and using a rapidly rotating brush.

Advantages

  • Eliminates the need for excavation or pipe-cutting
  • Compatible with a broad range of distribution pipe diameters (φ75–350)
  • Allows cleaning to be performed with only a short interruption to supply, thereby causing little impact
  • Enables a long distance of up to 200 m/section to be cleaned on both sides of the insertion opening
  • Materials that can be removed: manganese, water scale, deteriorated seal coating, etc.

*This method has been jointly developed by the Tokyo Metropolitan Government Bureau of Waterworks, TSS Tokyo Water Co., Ltd. and Kubota Corporation.

Leakage detection

TS Leak Checker(time integration-type leak detector)

We take measurements from service pipes, water meters, and other such equipment and detect the sound of water leaking in their proximity. When it is used to take measurements for service pipes, water meters, and other such equipment, the TS Leak Checker distinguishes between the continuous vibration sound associated with leaking water and other transient noise through time integration to judge whether any water leakages are present in the surrounding area.
This device is easy to operate and can be used to take water meter readings at the same time, thereby reducing the costs involved in conducting leak detection work.

Advantages

  • Allows anyone to detect leaks easily
  • Can also be used during the day without any noise disturbance or other unwanted sounds (reduces the need for night-shift work)
  • Reduces the measurement time (1–5 s)
  • Compatible with a wide range of piping (PVC pipes, etc.)
  • Equipped with a built-in memory that can store up to between 2,000 and 3,000 leak detection data items
  • Equipped with built-in Bluetooth technology (for the wireless transfer of the measurement data to PCs, etc.)

TS Leak Checker

This device won the IWA-PIA2010 East Asia Grand Award in the Operation/Management category.

The International Water Association (IWA) presents its Project Innovation Awards (PIA) to recognize and commend excellence and innovation in water-related engineering projects.
