Re: Storm Water Solution 7Jun 27, 2017 6:49 pm Having the roof drainage plumbed to a detention system wouldn't be a problem with the "very slight slope" as described but the surface drainage is another matter. Most often the two are combined as an expensive pumped system and this requires two large pumps operating in duplicate to prevent one pump frequently cycling. The problem with pumped systems of course is that pumps require power but continuity of supply cannot be guaranteed during a big storm. I am a strong believer that there should be ground water recharge points installed on properties for a number of environmental reasons but most councils are not forward thinking. Having a roof drainage detention system and excess surface water diverted to a groundwater recharge point would have both environmental and cost benefits in your case. Perhaps you could investigate this possibility for your situation. You need to keep in mind that the BCA is promoted as a performance based document, something that bureaucrats often overlook in their zeal to look for applicable regulations. 3in1 Supadiverta.
