3 
per head ; while 700,000 gallons are delivered in the higher 
division of Wickham and part of Fortitude Yalley containing 
10,000 persons, being at the rate of 70 gallons per head. 
It may be remarked that in the former district the 50 
gallons includes street watering, while none of the streets are 
watered in the division where 70 gallons per head is consumed. 
The census of 1876 shows nearly 22,000 as the population 
of the Municipality of Brisbane, with 9,000 in the adjoining 
suburbs, making a total of 31,000, of whom only 16,000 are 
within the range of the present w r ater supply from Enoggera, 
leaving 15,000 unsupplied except by tanks and waterholes, which, 
as the population increases, are every day becoming more pre- 
carious and unwholesome sources. 
Thq.s while the Enoggera Reservoir is being drained at the 
rate of rilore than 40 per cent, above its capability of continuous 
supply, there are still 15,000 persons yet to be provided with 
w r ater, irrespective of the prospective increase of population, 
which from the census of 1876 may be computed at 13 per cent, 
per annum. 
Having thus ascertained that the water supply from 
Enoggera is inadequate for even the present requirements, the 
question to be considered is, from what source is the deficiency to 
be obtained ? 
On the northern side of the city the valley of Kedron 
Brook and the South Pine River present themselves ; but these 
watercourses occupy such depressed localities that it would 
involve the double expense of constructing storage reservoirs 
and pumping to raise the water to the higher portions of the 
city. The supply from Kedron Brook would be very small, and 
it would require at least 15 miles of main pipe to bring water 
from the South Pine River. 
To the south, the Logan River would supply a large quantity 
of the best water in the Moreton district ; but as it would have 
to be pumped from a level scarcely above high-w r ater mark, and 
conveyed a distance of 22 miles, the cost is an almost insuper- 
able objection. 
To the south-west of the city, the Brisbane River, above the 
tidal influence, presents a considerable volume of water of fair 
quality, which, though inferior to the Logan, is better than that 
from Enoggera. 
The valley of the Brisbane is so nearly level that the tide 
carries salt water about five miles above the junction of the 
Bremer River, so that the first point at -which fresh water could 
* be obtained is 16 miles from Brisbane along the shortest prac- 
ticable line on which pipes could be laid, the surface level rising 
to 170 feet above the river in several places, though there would 
not be much difficulty in reducing the level of the pipes to 120 
feet by a few short tunnels.
