Flood pump drainage system

In the winter or during heavy rain periods the lower barn has been flooding as the land drains down through the barn from the hills above. To divert the water I have created a flood pump drainage system in the barn. Starting to dig a hole in the far corner of the barn:

Nearly deep enough for the bin:

Bin in situ:

Digging a channel all round the bin :

Filling the channel with plastic:

Then lining the channel with gravel to filter the mud from the water (so you dont block the flood pump)

A cheap drainage / ditch pump which has a float which activates the pump:

Installing the pump with PVC pipework:

Testing the pump activation with a hose:

We then ran pipework along the wall and out to the front of the barn where there is a drain in place.
