City of Guelph- Arkell Aquaduct Emptying Analysis

C3 Water completed an analysis to verify the feasibility of draining the Arkell aqueduct for the City of Guelph. The intent of the analysis was to calculate the time required to remove all water in the aqueduct which originates from groundwater under the influence of surface water  (GUDIWEF) while simultaneously replacing it with water from groundwater sources.

City of Guelph Water Supply & Distribution System Energy & Energy Cost Optimization

In order to facilitate modeling analysis of the ability to achieve power and power cost savings, the project team met with Guelph Hydro to establish the calculation protocol for power cost for each water supply and distribution facility within the City of Guelph. The calculation is a complex one which factors in elements such as the Hourly Ontario kW∙Hr Energy Price (HOEP), the monthly 15 minute maximum instantaneous kW power consumption, Distribution Surcharges, time of use rates and others. These are integrated into the total cost differently depending on the size of the electrical service and averaged monthly maximum instantaneous power consumption for the service. The calculations are developed in e.RIS, Eramosa’s Reporting and Information System. This software has direct links into the SCADA system database and pulls power consumption, real-time, from each site within the City of Guelph’s water supply and distribution system. Automated reports provide daily and monthly site power consumption and cost metrics to the operations management team. These reports are used to establish the baseline operational condition and analyze the improved performance when changes are made.

City of Guelph DMA Planning & Implementation

The City of Guelph, Water Services Department with the help of C3 Water Inc. financially justified five year program to implement 26 District Metering Areas (DMA’s) throughout the City of Guelph’s water distribution system, as shown in the map below. Economic justification of the use of development funding to build out the DMA program has been made through the deferral of capital costs associated with the development of new water supplies realized by reducing water loss. Economic justification was based on an average of 2.5 chambers per DMA, but to date the average number of chambers per DMA has been 1.9.
