Water tank drain pipe

This is a better shot of Richard Kilburn, this time tamping concrete.

We decided to remove the low wall and threshold stone steps at the main entrance in order to provide a more stable base for the curtain glass wall and entry staircase. In so doing we exposed the cast iron pipe that once took water from the tank when it was necessary to drain it. The pipe, sprayed blue here, was soon to be concreted in (below) but hopefully there will be room inside the building to preserve a stump of the vertical pipe. The stone wall will be rebuilt to the level of the screen wall's base.
