Where does the water go?

A letter from WR Maynard (Peninsula News, August 23) set off an itch in my sub-conscious which has been nagging at me since I came here just under two years ago.

WR Maynard wrote of the demands on infrastructure, particularly roads and drainage, to be created by the largely "residential 2b" zoning of the Peninsula.

We are blessed with a network of tree-lined creeks, which ultimately empty into the beaches and waterways.

These seem to be coping with the present wet and dry times, however I'm now wondering where all the stormwater goes when the rain runs off the building roofs into the gutters and thence down into the stormwater pipes.

Where to after that?

Do the stormwater pipes empty into the creeks, or do they go directly to the sea?

If the former is the case, are we going to have to keep a boat handy when the number of residences is doubled or tripled, all the streets are kerbed and guttered, and all rainwater goes via the creeks?

I'd appreciate it if someone could put my mind at rest - or not - on this niggle of mine.
