Murnane Service Reservoir was completed in 1956 to provide water storage. Decades later, the 22km Murnane Pipeline added another connection between this part of Singapore and the city. Its history explains a less visible side of Bukit Timah: the infrastructure that helps drinking water reach people beyond the neighbourhood.

A water-storage milestone in 1956
A water-supply study published by the Institute of Defence and Strategic Studies, now RSIS places Murnane Service Reservoir’s completion in 1956. It discusses the reservoir within the post-war expansion of Singapore’s water system.
The starting point is storage. Finding a source of water is only part of supplying a growing city; the system also needs places to hold water before it continues towards users.
The 1956 date makes Murnane part of a longer story than the recent construction associated with its name. A facility and a later pipeline can belong to different generations of work while contributing to the same basic task.
The National Archives also holds a north-west Singapore road map record whose description includes Murnane Reservoir alongside roads, railways and settlements. That is a useful starting point for placing water infrastructure back into the neighbourhood map.
What does a service reservoir do?
PUB’s explanation of service reservoirs says they store drinking water from treatment plants before it is piped to consumers. They provide a buffer as demand changes during the day. Conventional service reservoirs on high ground also help maintain water pressure through gravity.
Think about the difference between a steady supply into a system and people’s changing patterns of use. Households do not all turn on taps at a constant rate. Storage helps bridge the difference between incoming supply and the moments when more water is wanted.
This is why the word reservoir needs its full context. A service reservoir’s role in the drinking-water network differs from the image of a large open lake surrounded by walking paths.
The distinction is useful when planning an outing too. A name on a map can identify a working water facility without indicating a recreational destination.
The Murnane Pipeline connected the story to the city
In its 2021 account of the PUB Green Run, PUB explained that a southern section of the Rail Corridor had been closed for construction of the underground 22km Murnane Pipeline, intended to meet future city water demand.
PUB’s 2023 annual report records completion in December 2022 of the potable-water pipeline from Murnane Service Reservoir to the city.
This creates a surprising link with a familiar leisure route. A person walking the Rail Corridor is using a landscape with a railway past, while the water project adds another layer to its modern history.
The two uses are different, but both concern movement through the island. One transported people and goods; the other carries water. Remembering both helps explain why changes along a corridor can involve much more than its visible path.
A public walk that gives the water history context
Use NParks’ official Rail Corridor website to choose a current public walking route and check notices. The reservoir and pipeline history can accompany that walk without requiring entry to a water facility.
For an accessible historical starting point, read our Bukit Timah Railway Station guide. For a different outdoor route, the Murnane Trail guide concerns a hiking trail; it should be planned according to its own route and difficulty.
A good question for a family walk is: what makes this place useful even when we cannot see everything it contains? Paths and planting are visible, while much of a water network is understood through maps and explanations.
Murnane’s story gives an ordinary tap a neighbourhood connection. Storage, a long pipeline and the changing needs of a city all sit behind the simple experience of water arriving when it is needed.
