Title: angle for waste pipe to drain effectively
Post by juco on Sep 29^th, 2010, 2:46pm

Having to get a new sceptic tank (not uk) there is a kind of trap just outside the property and from there it looks like a 6 inch pipe to travel approx 10 feet to the tank. The new location will be approx 30 feet from this `trap`. Now although they say this will be ok I dont trust them (turkey) what sort of angle (incline) would this 30 foot section of pipe have to be to work efficiently? and take the waste from the trap to the sceptic tank.

thanks

See Table 6 and possibly Table 2.

Otherwise 1:40 (25mm per meter) minimium seems to be a common rule of thumb. Also works for driveways and patios.

I seem to recall 1:40 for 4" and 1:60 for 6"

Your lucky to have larger than 2 or 3" over there!
