Large processes and systems such as water and wastewater utilities can be complex to operate especially in an optimal manner with respect to performance, energy use and costs. Energy is costly and the market has variable and volatile rates. The opportunity to improve performance, reduce energy use and reduce operating costs is to use smart / intelligent systems based on optimization, modelling and predictive technologies.
We can provide an assessment of your process and the potential benefits to implementing a real-time operational optimization system, including integration into existing process control and/or data management system.
Variable Speed Pumping
Optimize variable speed pumping with regards to pump efficiency. This maintains overall efficiencies in the midst of large changes in, for example, a pumping station’s suction pressure. For large pumps this will lead to substantial savings in energy use and costs.
Multiple Energy Sources
Optimize and use the least cost energy resource, with online monitoring of energy rates (electricity, gas).
Water System Optimization
Large scale water system operations can be optimized with respect to energy used cost of operations. The approach considers variable and changing energy rates.
ETA staff played a lead role in IBI’s large-scale intelligent/optimized water transmission control system, creating smart cities through managing critical
infrastructure in a cost effective, sustainable manner. The system resulted in savings of over 16 Million kWh over a six month period.
Wastewater System Optimization
Wastewater Collection Systems operations can be optimized with respect to reducing or eliminating overflows and operational energy cost. Using predictive control, operating and maintenance costs can be reduced. For large pumping stations, payback can be less than a year
