"With regard to direct water supply to the Walled City Mr. N.T. Whitworth (Chief Engineer/Distribution) stated that Waterworks would find no difficulty in providing separately metered supplies to the lower floors of the buildings on the periphery of the City. However, it would be diffiuclt to provide house service to higher floors due to lack of room at ground level for pump tanks and pumping installations. Space to accommodate a large number of separate meters might be difficult to find.
As to direct water supply to premises in the heart of the area, this is affected by the difficulty in pipe-laying as well as the complication in arranging for different types (i.e. domestic and trade) of supply. However, the purely technical problems can possibly be
A detailed survey would be required to establish feasibility."
overcome.
The technical problems seem to revolve around the questions of pipe-laying, supply to upper floors, and the capacity of the drainage system to handle the additional throughput once household service is provided. These problems must be known in detail before Government can commit itself to
providing a household service, but the indications so far are that these problems may not be insurmountable. These indications include:
(1) the existence of an already extensive system of
household water supply derived from artificial wells and (illegally tapped) Government mains. In the latter instance, random sampling/testing of supplies within the City area by WWO have shown fairly conclusively that "water from Government mains is being used on a broad basis, usage not being limited to particular areas, indicating that the internal arrangements for supply to the various premises are pretty well integrated" (WWO memo to CDO(KC), T.C. (6) of C/58/C II of 16th January 1974, copied to Secretary of Security).
(2) the existence of five meters serving charitable
organisations, a fact which demonstrates, at least to the minds of the Walled City's residents, the feasibility of more meters serving households.
(3) the fact that the Walled City's drainage can, with
continuing minor improvements undertaken by CDO(KC) and USD, still handle the present household effluence, and with the improvements proposed in this paper, there is no reason why it will not handle the increased load which will accompany a household water supply.
