Dear Reza,

if you do not find the right content in the report, please have a look at this report: http://www.ikt.de/down.php?f=12

If it might be a problem of the language I would use google translater to get an overview what is written in the report.

I you have some question in detail it is possible to contact the project managers at IKT:

Serdar Ulutas or Marco Schlüter. You will find their E-Mail-Adresses on the homepage of IKT.

Especially Marco has tested sewer cleaning equipment of different network operators in germany.  In many cases they were i. e astonished that the pressure at the nozzle was less than 100 bars.

Good luck

Christoph
