your comment above states: Is it an acceptable strategy to capture the rainwater into tanks and discharge it into the public sewers after the rainstorm reducing the peak discharge? This is a common strategy for reducing peak rate, which will help you comply with SSc6.1, but you'll need to add onsite reuse or infiltration to meet SSc6.2 requirements. can you provide more guidance on this? Our Civil Engineer does not agree with this as an acceptable strategy.

This is a common stormwater management approach that has been in practice for the past 40+ years. Retain stormwater in something (basin, tank, cistern, milk jugs, whatever) ... and slowly release into something, whether it is a storm drain, stream channel, river, etc. so that the rate does not exceed that before development. The key word here is rate, this does nothing for volume, however.

Depending on the option being pursued you also need to reduce the QUANTITY... slowly releasing it reduces the rate but not necessarily the quantity...
