Using ACO drain for guttering downpipe?

[flanagaj]

We have a level threshold around the whole house and therefore we need to install ACO drainage.  As space is tight down the back of the property, I was wondering whether the downpipes from the guttering can feed into the ACO drain, instead of having to have a separate pipe system for the guttering downpipe.  The tech architect who did our drawings has drawn an ACO on one drawing, but then seems to have drawn standard underground 110mm pipe for the guttering.

What sort of pre filter / sump do you have before the rainwater tank. 
if you run acco drains into it it will be full of sediment in a short time. 
or is it on the drawing to keep someone happy.

I dont' think the TA even though about that 😞

A sump before the tank makes a lot of sense.

Great to see a rainwater tank. What capacity? How will the water be used?

You can put a catchpit just before the tank and it will catch all the dirt. I put one in before a 10m3 tank and it never needed attention in the 15 years I had ownership. 

Catch the leaves before they get on the system.

100mm pipe has to stay. Aco can feed into it.

I still need to size it, but thinking 5000 litres.

That's a good size. It will catch and hold a big downpour, which is important in a dry spell. Depending on cost and space available, consider 2 smaller tanks.

I'm planning one now, and it will only be for garden watering. So I can't see a problem using a redundant plastic oil tank.... they are free from any heating plumber or on Facebook. The oil traces will be insignificant.
