The Toronto Demonstration project

- how well is it working?

The Toronto Healthy House includes on-line monitoring of the Water systems, the monitoring has been sponsored by CMHC. Each home is seperately monitored for turbidity and water use. In addition, physical samples are taken and analysed in the Ministry of Environment Labortoties The eastern home is monitored for system function and control..

The charts below are automatically updated on the schedule noted.

Turbidity in the Western House

The western homes turbidity is calculated every ten minutes, this chart is updated every ten minutes. Turbidity in the Healthy House is a rough guage of water quality. It is not proof of high quality water, however process upsets and changes can be tracked using it. It is one of the few basic water quality elements that cna be implimented automatically. The turbidimeter employed is a HACH 1720d process turbidimeter. Click on the small chart to get a bigger one.

Hourly Water Use in the Western House

The western homes water use is read every ten minutes, this chart is updated every hour. The home has three meters, measuring potable water use, reclaimed water use and water disposed of. The meters are ABB, producing an electrical pulse. The pulse is read by a Modicon PLC which performs the counting. Click on the small chart to get a bigger one.
