Water Pumping Stations

---

In 2020, CMA Systems  were awarded a contract to automate two water pumping stations which were constructed to allow the storage & distribution of water for operational purposes. The current primary water source to the pumping stations was via a mains supply connection.

The pumping stations were overhauled and refitted with a water borehole extraction, water treatment (chlorination) and delivery systems, supplemented by a connection to the mains supply system.

The pumping stations Control & Safety system functions were provided by Programmable Logic Controllers (PLC), based on the Siemens SIMATIC S7-1200 series Controller. One Process Controller and one Safety Controller.

The system is used for allowing peak pressure to be increased at times of high demand, incorporating control for:

• Limiting quantity of water extraction from each source 
• Storage tank level control
• Delivery pressure control
• Manual / automatic control
• Water quality control
