23 Water Street North, Kitchener, Ontario
The mission of The Church of Saint John the Evangelist is "to fish and to feed. Jesus calls us to make disciples by embracing and nurturing all persons who seek to deepen their communion with God in his name."
St John's was paying for thousands of litres of potable water every year to irrigate their extensive gardens. The rainwater from the roof of their building was directed to storm sewers adding pollutants and volume to local waterways.
2,000L Above Ground Cistern: Rainwater is collected from 1/3 of the west sloping roof of the church in a 2,000L above ground cistern. A solar powered pump makes irrigation convenient.
500L Below Ground Cistern: Overflow from the above ground cistern is piped into a 500L below ground cistern that will feed a bubbling water feature in St. John's planned contemplation garden.
1,000L Rain Garden: Overflow from the below ground cistern is piped to a 1m x 5m x 0.5m rain garden with a capacity to hold up to 1,000L and infiltrate it into the ground within 48 hours. By harvesting and infiltrating roof water St. John's helps to keep water out of the storm sewer, reducing impacts on local waterways.
Maximum Capacity: 3,500L
Estimated Diversion Per Year: 83,000L
Project Cost: $8,000
(Above ground cistern $2,500, solar panel and pump $3,000, underground cistern $1,500, rain garden $1,000)
Stormwater Credit Eligibility: volume 8%, education 5%
Volunteer Hours Contributed:150
"The Green Passion ministry at St John's collaborated to launch this environmental project. Many parishioners feel very proud of our accomplishment in this step towards harvesting rainwater. The community will see that it is possible to store and divert rainwater from storm sewers and take care of creation."
