Water management software: monitor consumption, detect leaks, and stay compliant

Most operators still manage water with manual meter readings, exported CSV files, and a patchwork of Excel sheets stitched together at month-end. The result: delayed data, missed leaks, and hours lost to reporting that should take minutes.

Willie is the water management software that changes that. It gives your teams real time visibility over consumption across every site, automates your regulatory reports, and flags anomalies before they become costly incidents.

How Willie addresses your water challenges


Cut operational costs

Real time data means real decisions. When your teams can actually see what's happening across your water systems (by site, by zone, by time of day) waste becomes visible and controllable. Our clients reduce their water bills by an average of 15%, simply because early leak detection and actionable data allow them to fix problems fast.


Reclaim time across operations

Automated data collection eliminates meter reading rounds entirely. That's an average of 5 hours saved per site per month — time your teams can redirect toward higher-value operations. Compliance reports for environmental regulators generate automatically, with no manual formatting or data consolidation required.

Maintain compliance without the burden


Document your environmental performance

Reduction in water usage feeds directly into your sustainability reporting (ESG, CSRD, DPEF) without double data entry for better operational efficiency.

It also demonstrates measurable progress against water reduction targets, which matter increasingly to regulators, investors, and the communities you operate in. Your commitment to sustainable development is (finally) documented.

Integrate without disruption

Willie's management software connects to your existing infrastructure without needing to replace it. It is compatible with all pulse-output meters regardless of brand or age, with no plumbing works or electrical installation required.

API integration with ERP and BMS systems means your data flows where it needs to go, eliminating data silos and enabling genuine data interoperability across your operations.

FAQ

Water management software - Frequently Asked Questions

Can Willie generate regulatory compliance reports automatically?

Yes. Willie automates the production of structured compliance reports, drawing on centralized data from your metering network to generate accurate, regulator-ready documentation without manual intervention.

Is the software compatible with our existing meters?

Willie is designed to work with all meters currently on your network, regardless of brand or model, without any modification to existing installations. Your current infrastructure is an asset, not an obstacle.

How quickly can the solution be deployed across multiple sites?

Full deployment (audit, hardware installation, and platform go-live) takes two weeks. Your teams are operational from day 14.

What system integrations are available?

Willie connects to ERP, BMS, and CMMS platforms via open API to optimize performance. Collected data flows directly into your existing management tools, removing the need for manual exports and breaking down data silos across your operations.

How does Willie detect leaks in real time?

The platform compares observed consumption patterns against reference models continuously. When usage deviates from expected behavior (overnight flows that shouldn't exist, sudden spikes in a given zone, etc.) an alert is triggered immediately, enabling rapid response before damage scales.

Does the platform cover both water supply and wastewater management?

Yes. Willie handles the full water cycle: potable water supply, process water, and wastewater management. This integrated approach gives operators a complete view of their water infrastructure and supports more sustainable resource management across the board.

Which industries benefit most from this software?

Any organization managing water across multiple sites: manufacturing, construction, healthcare, hospitality, food production, retail parks, and more. If you have a complex water network and regulatory obligations, Willie is built for you.

How is this different from a basic remote reading system?

A standard remote reading tool collects consumption data. Willie goes further: it applies intelligence to that data, surfaces insights, automates compliance processes, and supports strategic decisions around system performance, risk, and efficiency. It's not a data collection tool — it's a complete water management platform.
