Calgary Smart Rainwater Capture and Distribution

Challenge Statement: "How will Calgary be able to plan for water demand in the future, and how can the citizen contribute with water conservation, while saving money at the same time?"

 

On average Calgary gets 317 mm of precipitation a year, most of it is absorbed by the ground or becomes runoff. Although not a new idea, capturing this water domestically and commercially would offset cost for the user and the City’s water infrastructure. For example, an average house with a 905 sq.ft. roof can capture 24,000 L of water a year, which can be used as flush water, or for gardening. The rainwater harvesting system would contribute with storm water management as well. Sensors would monitor the entire system, providing live and accurate data that will help in planning, not just at the Municipal level but also at the user level.
