Regulatory standards are becoming more and more challenging to live up to, and require extensive documentation . even contingency plans for the unexpected. Another major challenge is Non-Revenue Water (NRW), which has a negative financial impact on water utilities, water resources and subsequently on the quality of the water itself.

Hydraulic Modelling Tool: How It's Used

Hydraulic modelling tool (Fig. 6) simulates the flow and pressure in the distribution network. Using real-time data to analyse and track the current situation, it enables operators to make better and smarter decisions, to optimise production and raise bottom line. Integrated with these modeling tools, there are a number of features and modules that enable you to achieve further savings on both operating costs and capital investments including:

  • Leak detection: To quickly detect new leaks in distribution network, with the most robust and reliable detection methods like Integrated Flow Measurement (IFM) and Night Line Measurement (NLM). You can also identify zones with leaks and signal alarm to the SCADA system to necessitate immediate action. 
  • Pump optimisation: To determine how the pumps in a distribution/ transmission network should operate at any given time in order to minimise the total pumping and energy costs for the network, while still supplying sufficient water to consumers. By combining pump efficiency, energy costs and water consumption, saving of up to 20 per cent of the pumping costs is possible.
  • Production optimisation: It integrates knowledge about the water producers within the network with hydraulic constraints and water supply, and identify the most economical way of operating the utility.
  • Pressure optimisation: To integrate the information from the SCADA system and the model to provide advice for optimal pressure operation of the network. Any reduction of pressure in the distribution network will have immediate and significant cost reductions.

Finally, water is the most critical resource issue of our lifetime, and our children's lifetime. The health of our waters is the principal measure of how we live on the land. Let us not wait for the wells to dry to know the worth of water.
