The Challenge Severe Drought and Water Shortages

Managing Scarcity After Crisis

We all remember the water crisis in South Africa in 2017, which was reported on nearly every news channel. Between 2015 and 2017 South Africa’s winter rainfall zone saw its most severe 3-year drought in more than a century of rainfall records.

In some of the cities in the Southern part of the country the government restricted water usage to a limited volume per person per day. After this tough lesson, it was quite evident that dramatic action must be taken to prevent recurrence in the future. The city of Port Elizabeth (Gqeberha) on the Algoa bay in eastern cape took this step forward!

The Solution Smarter Supply With Real-Time Control

Cloud-Controlled Pressure Management

The DELTA full modulation controller was installed on Oct 2022 in Nerina Road , PE (Port Elizabeth).

The DELTA controls a 6”-720 valve on the inlet of DMA (District Metering Area), adjusting the supply pressure to the area in proportion to the varying demand/flow rate.

This battery-operated cloud-based controller allows the water utility remote control of the PRV (Pressure Reducing Valve) and the monitoring of the system behavior. This allows the system’s owner to make educated decisions based on real-time measurements. Additionally, the controller enables the modification of settings to enhance the system’s efficiency and minimize water losses.
