Leakage Management Module

Leakage Management

Designed in line with UKWIR (UK Water Industry Research) best practice guidance, these leakage modules allow users to create multiple methods to run leakage calculations within a range of parameters.

Whether it’s unmonitored zones or identifying leaks, the Leakage Management features enable you to drive better results, reduce water loss, and enhance decision-making.

Leak Size Estimation

Using Minimum Night Flow figures, this module is able to produce an estimated volume for a given leak that has recently been repaired.

Estimation methods can be configured to determine the exact method preferred by the user to estimate the size of the leak. Leak Size Estimation figures are stored against imported jobs and job data.

Leakage Calculation – Outside Continuous Monitoring

Multiple methodologies of Leakage Calculation are catered for and can be calculated simultaneously (including different night flow minimum methods).

Manual and automatic calculation of leakage is provided, and a user can start a calculation and shut the application. Monitoring of the calculation enables users to track progress and review previous runs. Control of which calculation method applies to each navigation tree allows calculation volumes to be controlled.

Leakage Suspension

The Leakage Suspension module allows the user to control automatic, and create manual, suspensions of leakage results.

This avoids the need to edit raw sensor data, whilst enabling leakage figures to be calculated in the absence of valid data. An audit trail of reason for suspension and the contribution to any weekly/monthly result at reporting levels is clear. Options to suspend based on missing, zero or outside typical demand limits, and replace with previous values are provided.

NRR (Natural Rate of Rise) Analysis

Calculation of the Natural Rate of Rise in leakage for DMA and higher levels based on UKWIR standard. Interactive calculation and review process enables any anomalous data to be excluded at each stage, with a chart to aid identification of issues.

After the bottom up, top down and hybrid stages are complete, a gap filling equation is used for data issues and a final DMA NRRd and NRRt is presented to the user. Reports display summaries of base data, issues and results for WIS and above.

Policy Minimum

Calculation of policy minimum leakage based on historic leakage results and interventions.

Automatic process with manual review to exclude outliers/spurious data. DMA base data is utilised to calculate the theoretical background leakage levels based on a UKWIR equation. Reports are provided to aggregate the values to higher levels and also targeting reports to identify areas furthest away from historic levels and/or background levels.

TML (Trunk Main Leakage)

The Trunk Main Leakage module enables users to calculate, review, and report trunk main leakage directly within WaterNet. It supports balance area calculations based on flow and consumption data, includes manual and automatic suspension handling, and provides clear reports and charts for daily, weekly, and monthly analysis. Results can also feed into the Water Balance for more accurate network loss reporting.
