I'm sick of lugging 25l containers back and forth so thought I would set up a couple of 200 l IBC's, some hose and a 12v boat bilge pump.....back the ute down the boat ramp and pump away

There's a rule 1100 gph pump or about 4,200 lph so if my calcs are right 6 minutes to fill.

Has anyone had any experience with this? ANy recommendations?

That's a really good idea Sven and we have thought about it our selves. Not sure where to start but I'd make sure it's legal and be very careful where you pump from. If you were in Melbourne, you wouldn't pump it from Altona :)

Would love to see your ute with two ton of water on its back trying to get back up the boat ramp tho! :D

 

[rosechaser]

200 litres x 2 only 400kg +/- that's no more than the boat and trailor

I'm in Sydney and have been going to Little Manly...I like it because it's in a marine reserve, quiet and very close to the heads.

Hope to set up next week...will let everyone know how I go...unless someone tells me otherwise beforehand

 

[Synodontis]

Oops! Read that as 2000Ltr IBC's, silly me.

Good luck in the setup, look forward to seeing the pics and hearing all about it.

another option is to use a petrol driven water pump (cheap ebay ones set u back $400-500 just make sure to flush them out after each use) and use a polycon on a trailer. The pumps will be able to pump u up the 1000l in under a min and since its a proper designed distance pumping tool, u can just run a hose from the polycon to the water and not even have to worry about going down the boat ramp, just park near it

I new I had read something somewhere :confused:

Have a look at this article guys http://www.atj.net.au/marineaquaria/watercollectionpump.html

Cheers

Sounds like a good idea - id just be careful of the water. With all the boats and ski's being launched there you might fins oil/petrol in the water - I have been trying to think of something similar but have about a 5 meter rise for the water to be pumped - i think im stuck carrying 20L containers up rock walls :(

 

[Synodontis]

What are the chances of getting within 20m of the shore line further down the coast? away from the boat ramps. Thats a very basic useable setup Magic linked to, I'm sure most could adapt it to suit thier situation.

 

[rosechaser]

Thanks guys, will let you know how it works

When I access the ramp it's when no boats are around....if there are i come backlater

 

[rosechaser]

The LFS told me that there is too much copper in the water around boat ramps....then he went on to say I should make up or buy his water....what do you think.

I know for a fact the copper based anti foul is now not meant to be used and trailer boats generally aren't anti-fouled.

Is there a copper test?

 

[n0rk]

It wouldn't be copper that'd be a concern, it'd be more contamination from fuels/oils and dissolved nutrients I'd be concerned about.

Hi mate,
I do the same , But i use a 3700Gp/h bilge pump , It will all depend on where you get your water from , I used to get it from a very calm spot , the bilge pump was great for this , Altho im glad i had the larger size , Remember to take into account head height , which will vary from place to place and the height of your ute . ( or what ever your pumping into )
Now however im pumping from a boat ramp that looks straight out to bass straight , Oh how i wish i bought the petrol pump as mentions above,
Its not so much the time, As its a big bilge pump with only a 400 odd liter tank to fill , But the fact that it gets rough , And being a bilge pump i need the car close to the water, = Rust . I will have to do something before the trailer really starts to rust Or worse , The car

Can't you just extend the hose and electrical cable as shown in the link above to get away a bit more from the water?

 

[Luke]

I have extended things , The problem for me is , There can be big waves and the farther away from the water the longer it takes ( head height )
So if the trailer is well out of the water then a big wave comes , All of a sudden the trailer is getting wet , Any farther away isn't really an option with a bilge pump , But that's on a bad day < on a good day its a breeze , But its an hour trip each way , So too far to go and not come home with water :)
I only do it because it seems like clean water , Or it should be,
Only a very small holiday village , no rivers close by , Boat ramp seems only used on the weekend by a few boats On Bass straight ,
Well its gotta be better that the Tamar river Water :)
But not as easy .

 

[Luke]

Im more trying to paint a picture for rosechaser , If the conditions may seem similar , Even sometimes , I would go the petrol , If its always going to be calm or at worst a bit of a swell , The Bilge should be fine , Keep in mind the height of your Ute tho .

 

[rosechaser]

Thanks guys am thinking about slightly bigger bilge pump now.

Both the ramps I go to are only 20 minutes each way one is protected (Little Manly for those in Sydney) and in the harbour but near the heads and in a marine reserve....I never go when at all busy, and never after rain.

The other is at Long Reef which is a protected ocean beach (unless there's a NE wind or swell) and that is not used a lot so by being careful and between the two should be fine.

Is there a loss in electrical capacity over distance or just the head issue?

Other thing is with 3 x 200l tanks and average of 1% water changes means a trip every 4 months which means I can avoid summer holidays and not too hard to work in with weather and tides that way.

You will get a voltage drop over the cable, so it is important to size it up based on the voltage u need at the appliance end and the supply voltage.

My plan for when my tank is on the way is to get use a NNR200 Crewcab truck with 2x 1000l Polycons (IBC) and use something similar to http://www.ebay.com.au/itm/NEW-6-5H.../270791952784?pt=AU_Pumps&hash=item3f0c754990 to collect water and store it in a 10kL water tank

 

[MagicJ]

You are planning everything on a big scale aren't you ;)

 

[BooY]

If one plans to do something well, one must plan and be willing to spend the $ to do it once and do it properly

You can buy a submersible pump that runs off 240v that can do 200l/m for around $600. All you need to do is attach a hose and drop it in the water.
