ACTUAL COSTS AND CAPACITY OF GASWORKS. 



239 



Service laying. The total number of services laid was 

 510, the average length being 46 feet 6 inches, the average 

 cost per service i, 75. 6d., and the total cost ^710. 

 Nearly all the services are f-inch wrought-iron tubing, 

 steam quality. 



Summary of works costs. The costs are now sectionized 

 under heads (a) land, (b) buildings, (c) plant. With an 

 expenditure of about ^120, the producing capacity of 

 the retort bench can be brought up to 26,000,000 cubic 

 feet per annum, allowing 10 per cent, for contingencies, 

 and taking 200 times the maximum day's production 

 as the annual output. Similarly, the holder, with its 

 110,000 cubic feet capacity, will suffice for a 22,000,000 

 cubic feet output, the purifying plant is equivalent to 

 48,000,000, the scrubbing plant up to 24,000,000 cubic 

 feet, and the remainder of the works more commodious 

 still. If the works is taken to be equal to 22,000,000 

 cubic feet per annum, therefore, it is well within reason.
