Terminology - Which kinds of drainage are those

[Braindrain]

Hello erverybody,

unfortunately I'm not a native speaker. That's why I have some problems with distinguishing different types of drainage.
If somebody gave me some short paraphrases or exemplaes of the following draiange-types I'd be really thankful.

Rainwater/ Above-grounf drainage/ U-drain/ Aewer-adoptable/ Sewer-surface water/ Land drainage/ Channel drainage/ Water management/ below-graund-drainage/ Internal water

Thanks a lot, cheers

Sounds very much like a college assignment question. I'm not sure what it is you're expecting: are you supposed to provide definitions for these terms?

[Braindrain]

I read those categories in a report referring to drainage. Due to the fact, that I'm neither drainage expert, nor having English as mother tongue, I really don't know, what is ment by those.
Unfortunately I don't have any futher information - there were just some companies listed, acting in those segments.

Rainwater - usually means guttering and downpipes

Above-ground drainage - pipes and fittings for use above ground: usually bathroom and kitchen waste

U-Drain - Probably means channel drains for use within paved areas: see below

Sewer Adoptable - pipes, chambers and fittings that are installed to a high standard and taken over by the local authority on completion to become part of the local infrastructure

Sewer Surface Water - as above, but for storm/surface water rather than foul

Land Drainage - perforated systems for removing excess groundwater form fields and gardens

Channel Drainage - U-shaped channels laid within a paved surface to collect storm water and deliver it to a disposal point. Also known as Linear Drainage

Water management - SUDS: see this page

Below-ground drainage - pipes and fittings for use underground

Internal water - pipes and fittings for use inside buildings. Probably includes sanitaryware
