Project Challenges
Byron Shire has a population of 34,574, yet attracts over 1 million visitors each year. Some areas of their network suffered from high burst frequency and high levels of leakage, which was proving expensive to maintain and reduce. Byron Shire Council were seeking a solution that allowed them to automatically maintain adequate levels of pressure for their customers, whose consumption patterns vary seasonally, and increase network efficiency.
Project Overview
Aquip Flowservices installed i2O’s Advanced PRV control solution at the inlet to the ‘School’ DMA. Upon commissioning the system, it was set to deliver the same fixed outlet pressure as before. Subsequently, oNet’s machine learning algorithms learnt the hydraulic characteristics of the DMA and constructed a headloss relationship at various flow rates. The engineers at Byron Shire then instructed the system to deliver specific critical point pressures during the day and night using oNet’s automatic optimisation mode.
Project Results
- Total daily flow reduced by 10%
- Pressure at the critical point reduced from 40m to 25m at night
- Minimum night flow reduced by 28%
- Background leakage reduced by an estimated 60 m3/day
- No low pressure complaints received since i2O optimisation began
