Smithfield began as Chisholm's Bush, after James Chisholm's 2,118-acre grant. In 1836 John Ryan Brenan bought 1,650 acres he called Donnybrook, sale yards opened in 1841, and the next year the area was renamed Smithfield Market, Town of Prospect; the markets closed in 1845 but the name stayed. A school followed in 1850, and the Coleman Home slab hut from about 1880 is thought to be the oldest surviving slab hut in Fairfield City. The rural township only really grew after the Second World War, when Housing Commission projects and private developers' estates filled in the paddocks. Prospect Creek divides the suburb between Fairfield City to the south and Cumberland Council to the north, where Smithfield shares the Smithfield-Wetherill Park industrial estate. At the 2021 census 77% of homes were separate houses, about one in ten townhouses or semis and one in ten flats, and 43% were rented.

Smithfield's drainage has been engineered more than most suburbs'. Blind Creek, once an open gully through the suburb, was mostly piped in the late 1980s and now runs underground as the Smithfield Main Drain. Prospect Creek, on the northern edge, flooded badly in August 1986 and again in April and May 1988, and Fairfield City Council has studied it repeatedly since, with a Prospect Creek Flood Study in 2004 and a floodplain management plan review in 2010. Away from the creek, the bigger risk is overland flow: the Smithfield Overland Flood Study (2011) covers a 292 hectare catchment through Smithfield, Fairfield Heights and Fairfield West, and the Smithfield West Overland Flood Study followed in 2016. Underneath is Western Sydney's shale clay, mapped by the state for its potential salinity. North of the creek, the industrial estate brings a different kind of plumbing: workshops, warehouses and food businesses with trade waste and backflow obligations.

Every part of Sydney has its own plumbing character, shaped by the age of the housing, the ground it sits on, and the weather it takes. Here is what we are called out for most often around Smithfield.

Council's overland flood studies map where water runs across Smithfield when the street pipes are full. A block in one of those paths needs its own pits, grates and stormwater line clear, with downpipes connected rather than spilling onto the ground, so roof and yard water gets away as soon as the system can take it.

Most of Smithfield's houses went up in the decades after the war, so their sewer lines are now sixty or seventy years old, laid in shale clay that swells and shrinks with the weather. Joints open, roots move in and sections sag. A drain that blocks again soon after it was cleared usually has a fault a camera can find.

Factories and workshops north of Prospect Creek often have testable backflow devices that must be checked every year, and food businesses need a grease arrestor serviced on schedule under their trade waste agreement. We test and maintain backflow devices and clear blocked commercial drains.

Common Questions

Fairfield City Council's Smithfield (2011) and Smithfield West (2016) overland flood studies and its Prospect Creek studies map the risk. Check the council's flood maps for your address. We can make sure your own stormwater drains as well as it can.

In an older house it is usually roots or a joint that has moved in the clay. Wipes and grease cause the rest. A camera inspection tells you which, and whether relining or replacing a section will stop it coming back.

Both. Prospect Creek is the boundary: the residential suburb south of the creek is in Fairfield City, and the industrial area north of it is in Cumberland Council.

Yes. We test and certify backflow prevention devices, repair or replace them when they fail, and lodge the results as Sydney Water requires.

Yes. Our phones are answered 24 hours a day, 7 days a week, including weekends and public holidays, and we send a licensed plumber out after hours for problems that can't safely wait, such as a burst pipe, sewage backing up or the only toilet blocked. There is a $0 call-out fee.

It depends on the job. You get a fixed price quoted before we start, and there is a $0 call-out fee.
