Case Study
Smart Water Metering | Zilvermyn Village, Cape Town
Water Utility Solutions (WUS) was approached to help deliver a fully integrated smart water management solution.
Project Type:Â Residential Estate Smart Water Metering
Location:Â Cape Town
Meters Installed:Â 43 smart sub-meters + 1 bulk check meter
Technology Used: Kamstrup MULTICAL® 21
Outcome: Accurate billing, leak detection, and municipal reconciliation
The Challenge: Manual Water Metering in Residential Estates
Manually-read meters in a residential estate is costly, inefficient, and unreliable. It also makes it difficult to manage water consumption.
Â
At Zilvermyn Village in Cape Town, water meters were read manually each month, consuming valuable time and resources. This process often resulted in errors, leading to inaccurate billing and resident disputes.Â
Smart Water Meter Installation & Monitoring System
Water Utility Solutions (WUS) was approached to help deliver a fully integrated smart water management solution, designed to modernise water monitoring, improve accuracy, and give the estate management complete control.
The smart metering infrastructure implemented by WUS included:
- A dedicated smart bulk check meter installed on the main municipal feed to the estate
- 43 Smart sub-meters installed across Zilvermyn Village to monitor individual residential units and common property consumption points.
This intelligent system automates data collection and provides real-time insights into water usage across the entire estate.
43 Smart Water Meters
2-year Smart Metering and Infrastructure SLA
30,000 litres of water monitored per day
100% Remote Data Collection
Results: Reduced Water Loss
The implementation delivered immediate and measurable benefits, including:
- Accurate, transparent monthly billing, eliminating inaccurate estimations and disputes.Â
- Early detection of leaks and abnormal consumption, enabled by regular reconciliations.Â
- Independent validation of municipal billing, with bulk meter data used to reconcile City of Cape Town invoices and ensure correct charges.Â
- Real-time smart monitoring, allowing for the detection of instant leak, continuous consumption tracking and faster response to potential issues before they escalate.Â
- A smart user App empowering residents with real-time visibility and historical insights into their water usage.Â
By replacing manual processes with smarter technology, WUS has helped transform the water management at Zilvermyn Village into a data-driven, efficient, and future-ready system that delivers cost savings, operational confidence, and sustainability benefits for both managers and residents.Â
