The Pumping Barge and Little Tug
These moved as each new extension of the suction hose was added

Assembling the Rigid Pipe on the Shore
|
This photo shows the rigid (steel?) beach lengths of pipe being assembled on shore. There were also heavy-duty flexible sections that were inserted as necessary to allow changes of direction, and I think that a lot of the offshore pipe would have had to have been flexible to allow the barge to be easily moved around to suck up sand and water from different areas of the sea bed. |

Looking East towards Joppa
This gives a record of the location of the activity. Joppa lies at the eastern end of Portobello Beach

The Beach End of the Pipe
The pipe is in situ, but not yet operating. There appear to be two outlets but I only ever saw one working.

The Initial Low Pressure Feed of Water
|
This was presumably to test the pipe's integrity. The man perched on the sand above the pipe gives an indication of the size of the pipe's nozzle and baffle. Cockenzie Power Station can be seen in the background. |

Pumping at increased Pressure
Water pressure has been increased, but the flow doesn't appear to contain much sand yet.

Pumping at Full Pressure
Maximum mix of sand to water. The position of the barge is in roughly the direction of Cockenzie Power Station.

Beach Regrading "Following the replenishment exercise in 1988, there was a 'beach regrading' exercise in 2011. This involved moving the existing sand back along the beach a bit, but not the importing of any new sand. You can't ever hope to beat the power of the sea, it seems." The Groynes "I think that the present groynes along the length of the beach were built not long after this replenishment exercise, to prevent or reduce further erosion or migration of the sand."
