3^8 WATERWORKS OF EAST LONDON. 



have, so as to get lig^ht and air into the back rooms, placed the 

 kitchens, bathrooms, and pantries back to back at a distance of 

 10 feet from the main building-, and that they are approached 

 under covered ways. 



So as to make the 3-roomed cottages in block as compact as 

 possible, and to economise in walls, they have alternately two 

 rooms in front and one behind, and one room in front and two 

 behind. 



The party wall will be carried up above the roof level. 



As I say. we have attempted no architectural features. On 

 the other hand, our rooms, if erected, will be moderately large 

 and well ventilated. Moreover, we have provided good kitchen 

 accommodation and ample provision for bathing, and for the 

 storage of food. 



Sewerage Scheme. 



The Council obtained a Provincial Ordinance to carry out 

 the Sewerage Scheme in jqi2, at an estimated cost of £210,000. 

 This Act was repealed under the General Act No. 18 of 1914, 

 excepting so far as the rating powers under the Act of 1Q12 

 were concerned, which we retained. 



The scheme was designed to deal with sewage at the rate of 

 60 gallons per head oer day for twice the present population, 

 and at a maximum flow of twice the mean. It was proposed 

 to store the sewage between tides, and after thoroughlv screen- 

 ing it. discharge it below low-water mark during the first three 

 hours of the ebb tide, about 500 yards east of the Blind River. 

 The method of disposal was approved by the consulting 

 engineers, Messrs. John Fletcher and Cathcart, W. Methven, of 

 Durban, and also by the Government engineers. Nevertheless, 

 now that the scheme is being prepared in detail, I propose to sug- 

 gest a modification of the outfall and method, of disposal. 

 Briefly. I propose that the new outfall should be at Nahoon 

 Point, and that the sewage should be discharged below low-water 

 mark, after screening, at all states of the tide. 



Hospital Drainage. 



In 1914, in collaboration with the architects. Messrs. 

 Cordeaux and Farrow. I designed a water-borne system of 

 sewage for the Frere Hosoital. with a septic or liquefying tank. 

 The effluent is discharged into the First Creek sewer. The tank- 

 is built in two compartments. The system is still under the 

 control of my department. Immediately after the construction 

 of the works I caused the sewage to run for 24 hours into 

 alternative tanks. This time was ultimately increased to two 

 or three days, and we are now running it continuously for a 

 week, first into the one tank and then into the other. The re- 

 markable thing about this tank is. that from the time it was. 

 started until to-day it has never been sludged.
