Hi,
I followed a link back here and thought I'd offer my experiences as they may help someone. I haven't read the entire thread, so excuse any repetition.
Firstly sewers, in non-combined systems, are usually quite explorable so long as they're not trunk lines which carry large amounts of flow. The trunk flow is not conducive to exploring, nor searching for coins and other interesting artifacts. In fact, I'd go so far as to say that anything which carries sewage is going to be a right pain in the butt anyway. Since the water isn't well, water, it'll be tough to go digging around for things when you can't see because it's
a) murky, and
b) digusting
Still it's well worth a shot but expect nastiness.
However, stormwater systems (in countries such as Australia where sewage and storm are separate) are right treasure troves. In particular the older systems constructed of stone/brick which allows the floor to deteriorate at uneven rates, especially in the areas below waterfalls. This deterioration creates little pools and crevices which catch heavy objects, such as coins, old metal nails, etc etc. The newer concrete pipe systems don't do this as much.
The other advantage to stone and brick tunnels is that the construction materials are not full of steel reinforcement which may have an effect on your metal detectors (disclaimer: I've never used one).
One great tunnel under Brisbane (Aus) is 100+ years old and has a series of stone tunnels connected by small waterfalls. Below each of these is a pool full of trinkets, on one particular journey there we pulled out $50+ worth of scunge-caked modern coins, a quantity sufficient for our post-exploration 3am pancakes. The waitress was not so amused. I believe we also pulled out some old australian pennies.
My best find however was a vintage fire extinguisher found half buried in a culvert in Manchester. It cleaned up quite well and my parents now use it as a garden ornament.
