Purecontrol – efficiency and predictability for water and drinking water pumping stations

In drinking water and wastewater pumping stations, one of the greatest challenges is the lack of predictability. Processes are constantly affected by variations: sudden increases in flow, daily fluctuations in load, changes in temperature, or rainfall events. In the absence of predictive tools, operation remains reactive, and energy consumption inevitably increases.

Purecontrol is built precisely around this challenge. The solution does not merely show what is happening within the system; it anticipates what is about to happen and adjusts processes before variations become critical. This is one of the key differences compared to conventional automation systems.

Predictability in Wastewater Treatment Plants

In wastewater treatment plants, Purecontrol uses predictive models and virtual sensors to anticipate the evolution of biological processes.

Through predictive control:

• aeration no longer reacts with delay after threshold exceedances,
• energy consumption is adjusted exactly to what is needed,
• the biological process remains stable even under variable conditions.

Based on existing implementations, Purecontrol has demonstrated average energy savings for aeration of around 15%, with values reaching up to 25%.

An additional benefit of this predictive approach is the control of N₂O emissions, an extremely potent greenhouse gas often generated by unstable aeration cycles. By anticipating process variations, aeration is maintained within a more balanced operating regime, thereby reducing these emissions.

Predictability and Efficiency in Drinking Water Pumping Stations

In drinking water supply networks, predictability is equally important. Pumping stations are often operated based on simple thresholds or fixed schedules, without taking into account the real dynamics of demand.

Purecontrol analyzes demand patterns and the historical behavior of the network, anticipates consumption variations, and proactively adjusts pump operation. As a result, the system avoids:

• unnecessary start-stop cycles,
• pump operation in low-efficiency zones,
• excessive energy consumption during periods of low demand.

According to data published by Purecontrol, this predictive approach enables energy savings of 10–20% in drinking water pumping stations, while maintaining pressure levels and service continuity.

Why Predictability Matters for Water Operators in Romania

For water operators in Romania, predictability means more than just energy savings. It also means:

• fewer emergency interventions,
• more stable processes during challenging periods (heavy rainfall, extreme temperatures),
• safer operation with reduced dependence on manual intervention.

Purecontrol is being implemented in Romania through a gradual approach, starting with monitoring and calibration phases of the predictive models to adapt them to the local characteristics of each installation. This phase prepares the transition toward fully automated control in a safe and controlled manner.

From Reaction to Anticipation

At its core, Purecontrol redefines the role of automation in water and wastewater facilities. The system no longer reacts to process deviations after they occur, but anticipates them and corrects them in advance.

For operators, this translates into lower costs, more stable processes, and genuine control over their installations—using the infrastructure they already have.
