Hi all... so i couldn't see this question/answer in any searches on here...
my scenario 600mm plastic inspection chamber (IC) with plastic risers vs brick built manhole both with metal lids. (650mm deep)
I've had contradicting advice that plastic IC's break when vehicles are driven over them and brick manholes are the the best way to go.
The position of drain will be in the front driveway (hardscaped) for a residential dwelling which is a self build.
There is an option to place the new drain further down the existing foul line which will be positioned in proposed soft landscape (non parking area) but that means due to the gravity fall existing drain, i will have to excavated down to a possible 1.1m deep.
Look forward to hearing of your experiences and thoughts on longevity and cost solution for this scenario.
Andee
