The cheapest option will be 'wavincoil' which is a ridged pipe with perforations. Comes in coils and diameters of 60-100mm or thereabouts.
The best way to use it is to dig a trench (ok you already have that bit done!), lay a weedmat type membrane down, lay the pipe, and cover with pea gravel, fold the membrane over the top and then fill the remainder of the depth with soil/turf. The more gravel you use the better the ditch will work, and to be really effective you take the gravel all the way up to the surface thereby creating a French drain. Your choice depends on whether you just want to carry existing flow or whether the area needs to intercept and drain water from around it.
For bigger trenches, you may need to use a rigid twinwall pipe, this starts at 150mm diameter and comes in 6m lengths.
