This reservoir was the first circular underground service reservoir locally built.  The characteristic of a circular appearance is that it can achieve the greatest area by the shortest perimeter, hence, reducing the cost of building the perimeter wall. 

At the time of its completion in 1904, the diameter of the service reservoir was about 46m, the height from floor to the vault was 6.85m, the storage capacity was 9,900m3, and the clearance between stone piers was 4m longitudinally and 3.7m laterally.

It would be difficult to construct the roof vault and the piers simply with bricks.  Cast in-situ cement concrete was the easy way to achieve the design span.  The loading from the topsoil and the concrete ceiling itself would be transmitted down to pentagonal profile granite spring blocks which run along in one direction, then down to the brick arches which imitate the Roman civil engineering works. 

The service reservoir was in such a unique appearance comprising a concrete floor, the 108 rusticated stone piers, the red brick arches, pentagonal profile granite spring blocks and the concrete roof which all came in different colours.

The site visit will be guided by officers from Water Supplies Department and concluded by a Q&A session hosted by the ICEHKA site visit representative.
