On 14 July 1926 the Lord Provost officially opened the western extension of the Promenade and the diversion of the Pipe Street outfall sewer.
As he pointed out in his speech, the amenity of the foreshore would be greatly enhanced by the diversion of the Pipe Street outfall sewer and the western extension of Portobello Promenade would link up the seashore walk from Leith docks with the old Promenade, giving a continuous walk along the sea front of three and three quarter miles.
The Councillors who were present during the proceedings received unmistakable proof of the popularity of the beach: Great crowds of visitors lay about on the shore in the brilliant sunshine enjoying the cooling breeze which came on from the sea, and there were hundreds of bathers and paddlers in the water.
In the past the Pipe Street sewer had poured forth volumes of foul matter on to the beach. The scheme to improve the drainage had been before the Town Council since the year 1905 and powers were obtained from Parliament in 1906 to construct a new sewer, but lay dormant until 1924, when the matter was taken up seriously by the Streets and Buildings Committee and a Government grant was obtained which allowed the work to proceed.
The original sewer was constructed in 1859 and was 20 inches in diameter and 250 yards long. The total length of the new sewer, was 2062 yards. Of this 369 yards at the Seafield end were of iron, 30 inches in diameter. 1360 yards was 6ft by 4ft wide egg shaped concrete and 333 yards of three feet diameter concrete tubes. The large 6 ft by 4 ft portion was to act as a tank in which the sewage would be held in suspension when the tide was in and would automatically empty as the tide receded into the deep waters of the Forth. The gradient of the new sewer was 1 in 600.
The work had been of a very difficult and trying nature, owing to the tidal waters and had been carried out by the firm of Messrs Bain and Brown, at a cost of between £50,000 and £60,000.
The surface, which was initially only of ashes for the moment, would, after consolidation, be laid with something of a permanent nature. There was now a continuous walk along the sea front from Leith docks to Magdalene Bridge, a distance of three and three quarter miles. It was a great asset to the city.
I have nothing to say and I'm going to say it.
