Packaged pumping stations

[eggsarascal]

Do any of you lads that do landscaping/drainage work ever install pumping stations? Wether they are for surface water or foul water.

 

I've just made two of these for a local fella that was putting up a log cabin that is going to be used as an office in someone's garden. The cabin will have a toilet and sink in it. The problem they had was not having the fall to get on to the gravity drain/sewer. This was easily solved by sinking a small tank in the ground with a pump in it to pump the waste water up to the house drains.

 

I was just wondering if there is any interest in these.
