drainage tips

[donthucktoflat]

drainage. can't live with it, can't live without it. i am looking for tips on techniques and methods of draining water from jumps.

i have some jumps that a few mates and i are building and they happen to have rather large bombpits. now does anyone have any fantastic ideas for strong and effective drainage as it is pissing down rain and we need to get some good digging done but there's puddles of water everywhere.

thanks in advance for your help guys

that is actually a quite good question, i would do some more reseraching and get back to you

I drew a picture! :D

A system simular to this works for our local bombpit jumps and it works quite well... however there isn't much rain to see how well it works.

yeah they are kinda on a slope heading across the lay of the land. we're thinking of having the pit slope slightly then digging the channels but this is ALOT of work as they will just drain into other pits... man i cant wait till this is sorted:D

Hey Man

I have a few ways of doing this

1. Dig a trench/ trough from the lowest point of the pit to somewhere where the water will drain into the ground quickly. If possible you could dig a deep hole and put sand in it and make it drain into that.

2. Soak it up with a sponge. Jump into the pit with a bucket and a big sponge and soak up the water squeeze it into the bucket continue. This would work depending on how deep your pit is.

3. Dig down deeper to the side of the lowest point of the point, deep enough to put a small bucket in it. Dig it in like a tunnel in the side of the wall and down... this may be hard but eventually it will be easy. Then get a broom and sweep the water into a bucket.

4. This one may be far out but get a long thick drill bit. (aprox 15mm) and drill small holes into the bottom of the lowest part of the pit. Water should drain through those and get soaked into the ground.


Some of these may be hard if the pit is really deep but the best method if it is deep would be to soak it up with the sponge.

the most best and most simplest way are either.

1. simply dig the bomb pit, slightly on an angle so the water will go to one area, then dig a deep ditch, (obviously deeper then the pit so gravity will pull the water from the angle into the ditch) from the ditch, put it into a main canal, (all pits drainage into one) and that will be quite deep and then shall be used as a creek to a water storage area, whether it be to the end of the pack and just let it soack into a middle of the bush or where it doesn't obstruct any of your jumps and it should soak out.

2. or you can get pipes at the bottom of the pit and re-cover them and bring that to a non obstruc way.

gluey, good suggestions. i like the bucket one. i also just thought of an alternative to the drill one. you know the spikes cricket unpires use to make the holes for the 3 stumps.. you could use one of those.. maybe :p

IMBAs favourites are called Scollops. Basically it's a shallow scoop taken out of the track with one ending up approx. 10cm lower than the other side. If it's stretched out over 1.5m say, it's very subtle and not noticable to the rider. Of coarse the faster a rider is hitting the section the further the scoop has to be spread out. It's a very subtle, with very little slope to one side, so it could be used on the approach to stop water heading down the track and pooling at the base of the transition. This is something they advocate for trails but it may be adaptable in your situation.

Yer this is what we do at our trails and it works a treat.

Just gotta watch out you dont role back down the hit and put ur foot in one and pull bike into your NUTS. GODDAMIT!

If you have a large bombpit try this method (takes a while but works awesome). Find a smallish good quality (stronger the better) wooden pallet. In the lowest part of the pit dig out a hole, the same width depth and height of the pallet. You can then simply slot the pallet into the hole. The the water will run through the gaps in the pallet... problem solved. Just make sure the sluts run opposite to the direction you will ride across them (same principle as north shore ladders)

Another method (which is supposed to work great although I am yet to try it) is digging a trench at the lowest point in the pit and across the width of the pit. Make it about 20cm wide, and 20cm deep. Fill the trench with small pebbles or gravel so it sits flush with the rest of the pit. The water will drain very quickly through the gravel and hence no more puddles in your pits.

I wanted to ask the question about drainage tips so I'll get this thread up again.
We've talked about draining water from jumps and around the base of jumps already but what methods have been used to drain water from the base of a berm? Some sections on a trail that I maintain have been renowned for being a mudbath and I've recently taken a berm away all together to get the water away from the track, it works a treat.
We have another berm where the lowest point where the water sits is the exact line that is ridden. It is a very important gradient edge of the berm and it needs to stay there.
Has anyone ever used poly pipe, mesh and gravel in any trail drainage to keep the water from settling in a puddle? It may sound far out but I have an idea of making the wall of the berm out of something solid, throw a few shovel fulls of gravel onto that, pack the dirt over it and have some pipes to get the water out of the corner.
Any ideas?

Havent Personally Tryed This But What if you got the drain pipe that are on the rooves of houses and the mesh the use to stop the leaves getting in and bury it and put pebbles in it then put the mesh over the top. But remember to have it at an angle.

here's a drawing of a drainage system that works really well, three easy steps, hope it works for you!

:confused: There is no drawing dude! I'm interested so please post it up, thanks.:cool:

sorry, i tried again but when i try and upload the pics, it says that it failed...
anyone know why, cause then i can post it

cheers!

I'd say the image is too big to upload. Can you resize it according to the limits and post it up?

dozer... been to mt coraba...awesome track......just a thought with ur water from berms problem...... het some ag pipe.... the stuff with the holes in it... wrap it in cloth so no dirt gets into it.... cut a curve about 10cm deep where the water sits... and past it by about 1M.... then rub the pipe through there... cap the 2 ends of the pipe......and run the pipe so its at its lowest point in the middle... so at each end maybe 10cm deep... in the middle maybe 15?? ... then get some normal solid pipe and make it stick out like the long bit of a 'T' and have that sticking out of ur berm pointing out the back... yet again at a lower angle then the bit where it joing the ag pipe.....

if all goes to plan the water should be affected by gravity and flow out easily of the pipe at the back of the berm and contine down the hill and into the creek :) . .lol

if this dont make sence pm me dozer and i'll add u on msn so i can add drawings to help explain it..... KEEP MT CORAMBA THE BESTEST! lol

Cheers mate, that sounds like a pretty effective way of drainage.
The track is soon to be longer and more "betterer"....;)

hey, thanks for the tip i put them on a word doc. to read it, just maximize the size hopefully this works for you!

cheers!

glad to help :)

my friend who lives in coffs says its raining today... so i guess you will find out pretty soon how my idea works for u..lol... it might be a bit costly.. so maybe try it on just one of the berms first.,.. if it works yay then do it on the other trouble spots :)... but a smart cookie like u woulda already thought of that so i am probibly sounding like an idoit..lol
