FUNCTION

​

The main function of a rain gauge is to measure rainfall amount

and intensity. Rain gauges relay data via a communications

channel to an analytic software solution. This software then

processes the rainfall data and alerts the network operator.

Warnings or alerts allow system operators to see at a glance

which areas need attention and what options might be taken.

BENEFITS

​

Rain gauges offer several benefits for wastewater utilities, including:

​

• Real-time model and telemetry data;

• Reduced flood damages;

• Reduced risk to public, staff & contractors;

• Reduced numbers of CSO spills;

• Scheduled pump and gate operation;

• Maximised use of system storage.

SYSTEM REQUIREMENTS

​

In general, there are no specific requirements to install rain gauges. The utility should utilise existing infrastructure as much as possible including weather stations and pump/lift stations. Remote monitoring stations may require solar power collectors and radio or cellular communications capability.

 

• The system should be able to output a signal compliant with the utility’s SCADA, typically analog 4 to 20 mA or MODBUS.

• There should be either a GPRS signal, an existing Ethernet connection, or Wifi router.
