The Bio swale
• The bio swale is a ‘drainage ditch’ or valley in the land that is used to channel water. Native plants are planted in the swale which cleanses rain and snow runoff as it is channeled into the larger raingarden area.
• Rocks and stones are placed in a swale to created a ‘dry’ creek. The grading design of the dry creek bed captures capture roof / surface runoff and channels the water to the lowest point on the land.
Berms/ Hills
• Soil that is removed to develop the swales / ditches is relocated to create berms/ hills. The combination of swales and berms are designed to move water to the lowest land point – the raingarden.
indentation in the centre area of the grounds. The combination of bioswales and berms enable water to drain into the low land- the raingarden. The raingarden is planted with native plants which have deep root systems that remove toxins (nitrates/ phosphates) from the water. A catchbasin has been installed at the lowest point to remove excess water during heavy rains.
