Sewer Systems 6

[dik]

I'm a bit out of my league, here.

Is it true that many cities have both a stormwater system as well as a sanitary system? It is my understanding that these are often combined into one sanitary system.

Is it common for cities to take run-off from roads and divert them directly to 'retention ponds'? I had thought that road run-off went to the storm sewer system via catchbasins to 'trap' sediment.

Can someone enlighten me?

Do they ever sample the water for toxins or heavy metals?

Sometimes. Sampling requirements will be listed in the NPDES permit.

National Stormwater Calculator helps find ways to reduce runoff.

And you should skim this site before referring to your state and local requirements.

Getting good at this takes time.

Not really a direct answer to your question but I've been enjoying the 'A Very Short Introduction' series to learn a bit of the basics of other disciplines :
