Just a quick question, what would be the min size for a man access rectangular inspection chamber approx. 1.7-2.0m deep?
Its for access to ducts, not drainage pipes but I would think the principle is the same.
Cheers
PS. just found this site, excellent info and huge coincidence I was brought up in Culcheth from aged 4 until I left at 20!

dont know the regs but cover would be 600 by 450 and i would have thought you need at least the same for inspections if not a little bigger

Fitted a 600 x 450 shallow type Trojan cover to a 2m deep stormwater inspection/collection chamber today - climbed down inside (to clean up afterwards) with ease.

Thanks for replies, I probably wasn't that clear in my origianl post. I meant the actual chamber size rather than the cover size. It would be a rectangular chamber.

that sounds like my waist and inside leg dave 
pasties are ok as long as you eat them at a 2:1 ratio

yes that was the problem,too much rabbit food not enough pasties
as an aside, as anyone who does building work knows, you need to eat to work 8 hrs a day digging,flagging etc. my missus survives on an apple and a rice cake all day at her keyboard,that just aint possible on site
going to buy a paslode nail gun now,now that is a boys toy!!

i never work alone on sewers ,its just too dangerous,in fact its not good practise to work alone on any building project in case of accidents.
most domestic runs should be vented surely??
got me thinking now

man cz its storm water. you never know what filters in m8. i was working on a storm run and had to have water tested because it made my eyes sore and got a skin reaction, imagine if i was in deep? this stuff flowed into the river and killed thousands of fish. they got a massive fine. as you know its best to lift the lids up and down the run for air circulation. always err on the side of caution.

The one in question we were involved in this week was a very dry storm drain. Wouldn't be too keen to go down into a foul one though......although we do far worse jobs with foul drainage though........

dry or wet the risk is always there m8. fumes are invisible....gas,exhaust etc.
