Hi
Just as a PS to  Muna' information.  This all works IF the sludge is not
contaminated  with toxic chemicals.

Unfortunately all city sewage systems are part of a  wider network of effluent
discharges from factories and this toxic brew  cannot be handled adequately by
even the best sewage treatment plants.   That is why the sludge is
contaminated with hazardous materials and why you  would not want to spread 
it on land.
Even on forests.
The only real way to  tackle such sewage sludge problems is to clean up the
factory  discharges.  Something that the City of Toronto successfully did for 
 a
handful of chemicals but the Toxic Use Reduction City By-law did not go  far
enough and met with alot of company opposition (dentists for instance who  
had to
implement more stringent handling of mercury).   I helped  them initiate this
planning back in the late 1990's.   All to say  this is another reason why we
need Toxic Use Reduction Planning for all  companies discharging into the 
sewer
systems of cities round the  world.
For more information on this visit www.turi.org or for general  information
visit our website under the Steps section called 'cleaning up the  
manufacturing
process'

It's all possible to do.   But it  takes a dedicated municipal government who
will pass comprehensive effluent  discharge limits and monitor/enforce them 
and
more importantly work with  companies to implement clean technology.
Something there is alot of  information on (UNEP Cleaner Production 
Programmes and all
the rest of the  international  clean technology networks).   But it takes  a
campaign 'kick'  and often sampling of sewage sludge to show just how  toxic 
this
stuff is and get change happening.
