NRW Reduction Projects – Design and Implementation
Hydrax’s experience and expertise supports the following crucial services:
Water Audits and IWA Water balances – evolution analysis
Based on NRW information, Hydrax will be able to show the utility baseline and evolution of particular Key Performance Indicators (KPIs). The proper analysis of this KPIs is fundamental to understand the water losses levels and the water utility efficiency challenges. Using the experience gained through a large number of projects and access to specific biography and knowledgeable sources, Hydrax can guarantee a quick data analysis and accurate diagnostic. The International Water Association (IWA) Water Balance, which is a renown and recognised water audit tool, will be complemented with a special selected efficiency indicator, some general and some particularly designed for the water utility under consideration.
Infrastructure condition assessment: GPSing and condition surveys for all infrastructure including network, water meters, valves, storage facilities, pump and booster stations, testing and calibration of bulk and district water meters, etc.
Field measurements: flow and pressures datalogging and data analysis.
Water distribution systems optimization: DMA’s (district metered areas) analysis and designs, PMZ (Pressure Management Zones) including Zero Pressure Tests (supply zone isolation checks) and system stabilization programmes.
A basics tools for network management is the sectorization principle: dividing the network into different ‘zones’ so the operator can analyse flow and pressure profiles into these different zones, identifying problematic areas.
Pressure Management and Advanced Pressure Management or … “the practice of managing system pressures to the optimum levels of service while ensuring sufficient and efficient supply to legitimate uses” … field measurements and data logging, evaluation of cost-to-benefit scenarios, pressure management designs (including field measurements, Pressure Reducing Valve (PRV) sizing and PRV installation designs), PRV’s installation, fixed or dynamically controlled, time- or flow-modulated; utility pressure standard limits.
Benefits of Pressure Management:
Energy optimization: energy efficiency programmes
Asset Management programmes: infrastructure condition assessment – including mains and service connections replacement programmes, rehabilitation and maintenance programmes
Network analysis modelling: hydraulic modelling and system optimization models.
Water System Operations: Operational Training, Maintenance Plans and Manuals
