Assessment Tools

Water Balance Calculation Tool

An Excel tool that helps the user to perform a water balance of the utility—a necessary starting point for NRW analysis and reduction. 

Resources:

• Non-Revenue Water Analysis and Reduction

Non-Revenue Water Financial Model

Helps users assess whether a particular combination of NRW-related investment conducted as part of a performance-based contract will result in a financial "go ahead" or not.

• NRW Practices Rating Tool

Terms of Reference Toolkit for Different Performance-Based Contracting Models

These TORs provide a foundation upon which more specific TORs can be built. It provides TORs for four different cutting-edge PBC models (Cost Plus, Self-Optimizing 24/7, Program Management, and DMA Rollout) and should be adapted to suit the local situation and specific scope of work required.

Component Analysis Model

This excel tool was designed to provide water utilities with a tool to undertake a leakage component analysis and to identify economic options for real loss reduction through improved speed and quality of leak repair, proactive leak detection, and pressure management. This tool was also designed to assist water utilities in evaluating options for implementing efficient and sustainable leakage control programs.

• Component Analysis Model

Trend Analysis Tool

The Trend Analysis Tool is a method to assemble utility context and performance data in a systematic and complete manner. This tool can help to: understand of the evolution of performance over recent years, benchmark current performance, and monitor progress over time.  The trend analysis tool complements other tools included with the Operations Manual.
