Scoop for removing dirt in stoptap chamber

[Threadjacker]

Round here Yorkshire Water have a scooping device to remove soil over an external stoptap, it has two 'buckets' and scoops dirt up which can be pulled out.

I've had a couple lately where I've just not been able to get far enough down and I've had to call them out.

Does anyone know where I can buy one of these tools, I've had a search around but all I get are JCB buckets, I don't know what they're called.

I use what I have come to know as a digging spoon. One could be extemporised with a large kitchen spoon attached to a broom handle.
That would be good for removing silt, but wouldn't put up with chopping through tree roots etc.

The 'pukka' ones have about a 3 or 4 mm thick steel spoon sized and shaped blade welded to a 20mm steel bar handle. A couple of transverse ribs welded across the blade help hold the load as you lift it.

The advantage over the clamshell arrangement is no moving parts to break or jam.
