But, that apply the use of an ozone-based water treatment and disinfection system to render rainwater potable when collected through domestic rainwater harvesting systems. Click the button above for the technical brief to see the comparisons of using ozone, UV radiation and chlorine as effective disinfectant and see which one is best.

This report by TRCA evaluates the performance of stormwater source control practices retrofitted into an industrial-commercial lot located in a densely-developed portion of Toronto that drains to the Malvern Branch of Highland Creek. The rainwater cistern and landscape irrigation system, [[Infiltration trench]] and three soakaway ponds. Performance parameters examined were runoff volume reduction, rainwater use/municipal water conservation, pond drainage rate and frequency and cause of overflows. Results show that the rainwater cistern/irrigation system and soakaway ponds/infiltration trench systems reduced runoff volume from their roof drainage areas by 64% and 89% respectively over the summer to fall 2015 evaluation period. Read more about these results and the subsequent recommendations for future designs and further research are provided in the report by clicking the button above.
