DQW – digital quality management for water supply
The DQW software is a simple and streamlined web solution for legally required self-monitoring, which also incorporates the new W12 industry guideline of the Swiss Gas and Water Association. It allows the responsible persons of a water utility to digitally record, manage, and track quality-relevant activities. At the same time, key operational documents such as telephone lists and contracts, as well as plant plans and photos, are made available to the user. With the help of the DQW tool, the well manager carries out his inspection and maintenance work according to the stored instructions. He documents the work and readings in the digital journal with just a few clicks on his tablet or PC – even offline if internet access is unavailable. If the plant manager discovers a defect during an inspection, he can record the necessary measures with corresponding priorities and responsibilities. The task list then displays all pending work and measures at any time, and reminders are automatically sent for due tasks. The DQW software is a practical and easy-to-use support for daily work to ensure quality assurance. The tool can be customized to meet individual needs. Initial data collection and technical support are provided upon request by experienced water supply engineers from Wälli AG Ingenieure.

ZoneScan AI – continuous monitoring of the water supply network
The ZoneScan AI noise logger uses artificial intelligence to set new standards for leak detection in water supply networks. The self-learning, cloud-based system is continuously evolving in global use. ZoneScan AI is one of the most sustainable innovations in the field of water supply network monitoring. Many municipalities and cities rely on this advanced technology. And experience shows: Thanks to the high system reliability, initial successes can be felt after just a few weeks. Here's how it works: ZoneScan AI analyzes the noise in the water supply network at night during low-consumption times. You receive fully automated alerts about leaks on your smartphone – pinpointed and in real time.
