Transmission Operations Optimizer
Our innovative water delivery system dramatically reduces energy consumption, and in turn, the cost of providing water to city residents.
Cleaner, safer, more affordable water delivery
Our Transmission Operations Optimizer (TOO) design is one of the world’s first large-scale intelligent water transmission control systems, effectively minimizing water pumping energy costs while ensuring service delivery standards – including pressure, flow, and water quality – are consistently met.
The optimizer is based on a series of system models, water demand forecasts, and control strategies as well as other information such as energy cost rates. It leverages established hydraulic quality and demand models in an integrated environment with direct links to Supervisory Control and Data Acquisition (SCADA) systems.
It can be manually initiated or run automatically, executing on a regular basis, or triggered by specific events such as energy rate fluctuations or equipment malfunctions.
Solving Toronto’s supply challenges
Originally developed for the City of Toronto and successfully launched in 2015, our TOO system serves a population of over four million residents – making it the the largest water system in Canada and fifth largest in North America.
Treated water pumping occurs at four filtration plants and pumping stations, floating storage at reservoirs and elevated tanks, and approximately 500 km of large transmission mains, ranging from 400 to 2,500 mm in diameter, that transport treated water from Lake Ontario up through the system. Water is pumped through a hierarchy of pressure districts with elevated storage facilities (reservoirs and tanks). Combinations of the pumping stations and floating storage facilities provide water to the City and Region’s local water distribution systems.
Over a period of six months, 16 million kWh of energy was saved – at a projected cost savings of ~$1.5 million/year based on kWh reduction alone.
