Land drainage - Information

[craigdonaghy]

hi i am looking for some information on how you find out at what depth you would install land drainage pipes at thanks ?

[eazybarra man]

Craig, The land drainage contractors association recommend a minimum cover of 450mm.
However, depending on the application and site conditions depths can vary
What is the application?

[craigdonaghy]

the application is for a large garden, the site conditions are very wet underfoot and if you start to dig the soil away the hole fills quickly with water

[eazybarra man]

Can you post some photographs on the site? This will give a better idea of the site, type of soil, surrounding area etc
is the house in a new development?
Are ther other houses/gardens surrounding yours?

Depends on the fall of the land and where your outfall is, 450mm is a bit excesive for domestic use.

300mm is usually plenty but as barraman says it depends on your garden and surrounding features.
