trash pump to remove silt?

[c***@hotmail.com]

Hi,

I have just moved my nb to a new mooring. The location is ideal except
the area really needs dredging to get the boat moored close to the
bank.

Someone sugested hiring a trash pump. Is this suitable? Does anyone
have any experience?

The stilt appears to be just very soft mud.

(I have tried mooring the boat as tight as I can, and letting the wash
from passing boats wash the silt away, but its proving to be a very
slow process.)

Cheers,

Chris.

IF this is a RIVER mooring and IF you want to take a small risk with your
prop secure your boat with the stern at the upstream end of the mooring very
securely.

Run full ahead whilst waggling the tiller from side to side, after several
minutes turn the rudder away from the bank. for a while, still in full
ahead.

Move the boat back a bit and repeat.

You will dredge the mooring this way and I know many river boatyards employ
this technique after the winter floods have banked silt up in their
moorings.

I also know of one proprietor who used his fleet of outboard day launches to
dredge a creek - spent a bit on water pump impellors though!


If its on a canal I think BW will take a great interest in any attempt to
dredge. I understand they have standards that such work has to comply with.

This works on canals too! * :-)
(It will only move silt and not the clay puddle.)

But it contravenes BW Licence Condition 8.4(b) ... :-)

Hmmm Ile wait till my license expires before I try that then ;)

I have tried running the engine, but its not cleared it. It is a heavy
(18 ton) 60' trad with two engines at the back, making the stern lower
than it should be.

Apparently the owner of the moorigs said that they had that area
dredged before using BW contractors. They put all the silt in the
middle of the canal, and it was all back where is was a week later
after a few boats had passed. Well done chaps!

The idea of the trash pump was to pump it behind a wall of timber
driven into the shallow area, perhaps with sackcloth to filter the
water from the sediment.

Then you'll need a waste disposal licence..., and if it's
contaminated....

Two engines on a narrowboat?
Are these both propulsion engines?

Gosh I need a waste disposal licence to move silt around on the bed of
a canal! I have been breaking the rules all this time by just moving my
boat around the canal network disturbing all that silt.... ;)

The other engine is for the generator. Not my idea It came with the
boat, but I mention it cuz its a 7.5Kw huge thing.

That's if you pump it out of the canal, not a lot of point pumping it to the
middle as it will just come back again

Yeah, as I said....

Seems to be precisely what BW do for bank protection in some areas, just a
few stakes at the canal side with sackcloth strung between them, backfilled
with mud and silt using a JCB fitted dredger.

I wouldn't be surprised if they didn't still have to have a waste
disposal licence to carry it out though.

I suspect they don't have to, as the 'waste' is still 'theirs' - they
aren't disposing of it or removing it from their 'premises', just
rearranging it on site.

They also arn't *actually* saying it's "waste" either!
The minute one uses the "W" word, you bring a whole ream of legislation into
play.
