Later sections were also roofed, generally with an arch to oviform. The form of the channel was a mixture of stone and brick in the lower half, with a sandstone arch roof.

The form of the open channels was generally a convict period shallow V profile which assisted in improving the flow of the stream in the late 1850s work commenced in covering the Bridge Street- Hunter Street section of Tank Stream. This (and other) sewers discharged directly into the harbour a situation that created discontent as social attitudes changed. Yet by 1826 Tank Stream had become an unofficial sewer, it became an official sewer in 1857.

Other dams were later added within the catchment area of Lachlan Swamps now located within Centennial Park. : 1 Tank Stream was the main source of fresh water until the completion of Busby's Bore in 1837. It filtered through the soil between Pitt and George Streets before forming a definite channel near King Street and flowing to Sydney Cove. The Tank Stream rose in marshy ground roughly bounded by what is now Elizabeth, Market, Pitt and Park Streets. Its foundations may survive within the streambed under modern Bridge Street. In 1792 a stone arch bridge over Tank Stream was constructed, replacing existing wooden structures. These measures were ultimately unsuccessful. In 1795 orders were made to prevent the grazing of stock or cutting of trees within a 15m distance of the stream. Yet due to the increasing population number of buildings around the stream and the loss of trees as land was cleared, runoff increased, which included human and animal wastes and domestic products. Īs early as 1791 Governor Phillip enclosed Tank Stream with a fence in an attempt to prevent stock muddying the water and later, trenches were cut alongside the stream in an attempt to catch runoff before it could enter the stream. In 1790 Tanks were cut into the bedrock of the stream (hence the name), the number of tanks is believed to be three or four, and are thought to have held 20,000 litres and been 5m deep. On 26 January 1788 the new colony was inaugurated. Sydney Cove was chosen for settlement as it "was at the head of the cove, near the run of fresh water which stole silently along through a very thick wood". The colony had originally been planned for Botany Bay, on the recommendation of Sir Joseph Banks who had visited the area with Captain James Cook 17 years earlier, but when no fresh water was found there, Phillip sought a better site, and found it in the previously unvisited Port Jackson. The area was chosen by the commander of the First Fleet, Captain Arthur Phillip, R.N., in 1788 as the location for the New South Wales colony for similar reasons. Īlthough it was unable to consistently provide water in dry weather, the stream also played a role in dividing the settlement, with the eastern side being held for government and administrative functions and convicts living on the western side. The stream is thought to have given the Aboriginal people fresh water, fish and other resources.

Excavations around Tank Stream have uncovered aboriginal flake stone artifacts made from water-worn pebbles. The catchment area around Tank Stream provided "a range of environments- marine, estuarine, rock platform, creek, open forest, wetland" all located within a short distance and able to provide a range of food and material.

The Gadigal (or Cadigal) people were the Aboriginal group most commonly accepted to have lived around the Sydney Cove area prior to European arrival. The history of Tank Stream incorporates aboriginal use of the land the history of European settlement the natural forming stream as a water supply and its later use for waste disposal and as a part of the stormwater system.
