Waterline from creek help

I have discovered a few spots which are extremely remote in steep mountains, and a good 4hr pack trip in. There is a main creek which is about 20ft wide and has many tributaries flowing into it from deep mountain country. I plan on growing along one of the steep mountainsides above one of the tributaries, and stringing out a waterline to my plot. I understand that the waterline must be flowing downhill from where it is put into the creek so gravity can do the work. I also plan on growing around 12 feminized lowryder #2, so just a small plot. Iam also going to burry the entire water line.

Q1: What is the best type of material to use for this waterline?

Q2: Is there a way to connect a flowstop/timer so the plants arent constantly being flooded with water?

Any advice from people who have done this sort of thing would be great, as this is my first time growing outdoors.

Earlier in the year I was trying to think of some remedies to this problem. An option we brainstormed was using a dripper/soaker hose.. Here's some info from:

Dripper Tube
- Very thin but tough black 13mm PVC hose. Has two blue lines on one side indicating dripper line. Inbuilt drippers spaced 10cm apart. Emits at only 1 litre per hour. Usually 15 metres in a coil.
- Place hose with blue line up and don't use high water pressure. If you can't squeeze hose with fingers when opening, the pressure is too high.
- Easy to install - needs special fittings, ie joiners and T pieces. However, kinks restrict water flow unless laid in straight line or gentle curve.
- Low, cost effective way to water plants in straight lines or gentle curves

I dunno if this would be something your interested in but its worth considering.
Even if you had a DIY system where you rigged up your own dripper and measured how much it emitted, then added more holes as needed, you should solve the problem.
Like I said, I've never used this method (We found a different grow place so we just stopped worrying about it) so if anyone has any tried and true solutions, fill us in.

Check out this website as an example:

There are a lot of commercial drip systems you could convert with a little creativity, the help of gravity and a stream. It would be a lot easier to use dripper kit parts than to try to make a home-grown system completely from scratch... and the cost isn't too bad really:

Regulating the flow (might need to add a pressure regulator as well):

And a filter would be a good idea since stream debris will be a problem eventually without one (check the website).

If you want to get really fancy you could even add a battery powered controller to control water flow beyond a constant drip system...

Just a thought, but make sure the stream you are tapping isn't too seasonal with it's waterflow or if it is, that your hose/line is well secured. Would hate to see you lose everything to a flash flood - which are too common with steep mountain streams.

ive never built one , but , hosepipe, 1- hosepipe thread x half inch pipe thread adaptor 3 -1/2 inch 90 degree ells approx 4 ft 1/2 cpvc pipe,and small can glue .to connect glue joint to half inch cpvc or if u have exp in plumbing , pex, but cpvc for less exp. drill 1/8 inch weep holes every 1/2 foot until u have circled plant weep holes must be pointed up. all u need to do is prefab, glue ure 90s up around plant . ure gonna suck on end of hose pipe to create syphon that will not stop as long other end stays submersed in creek, then glue last joint tada!! if more than one plant buy some tees and branch off and repeat!!!
