Smart Water Grid Two-Way Fixed Communications Network

Turn your Water Grid into a Smart Grid Platform

Worldwide recognition has developed for the real need to increases intelligence throughout the water network using a 2–way fixed network communications solution enabling access to every end-point in near real-time from the pumping of wells to the customers’ house. This is a “network” that can monitor events in real-time, control every part of the water network while immediately and automatically alerting the system operators.

Reliable 2-way fixed network communications enables a variety of applications such as:

  • remote meter readings on demand;
  •  synchronisation of meters’ real-time-clocks;
  • identification of non-revenue water within the hour;
  • customer access to granular consumption data via an online portal;
  • water forecasting to enable the shifting of some pumping operations to lower electricity tariff periods;
  • remote control of flow, pumps, pressure controllers, and valves across the water network in near real-time;
  • pre-payment functionality including charging of the smart meters via the communications;
  • extension of meter battery lifetime up to 20 years by communications handshake enabling meters to revert to sleep mode when communications have been confirmed;
  • remote firmware upgrade of network elements (meters, repeaters, concentrators) via the Meter Data Management (MDM) software;
  • tampering alerts in near real-time;
  • remotely update Time-of-Use (TOU)/step tariff tables.

The system gives utilities the peace of mind that the solution they deploy is already well established and proven, and will create a secure, data highway for mission critical applications like smart metering, as well as a clear path to the utility network needs of tomorrow.

Quick Specs:

  •  True two-way fixed network communications with high-performance reliability, availability and scalability
  •  Single concentrator (aggregator) can handle up-to 40,000 endpoint.
  •  Multi-layered security (from endpoint to user interface).
  •  Unlicensed frequency operating in 850-920Mhz.
  •  Protocol: RF – Modbus;
  • Bandwidth: 52kbs both sides;
  • Communication distance 1.5klm line of sight (LOS) 300m built up (depending on local conditions) from meter before requiring a repeater;
  • Star Network – Certain meters can be configured to perform as repeaters. The repeaters are mesh.   It is a learning system.
