Manly facts that change a plumbing job
Mostly apartments
At the 2021 Census, 76.8% of occupied homes in the suburb were flats or apartments and 11.3% separate houses. 51.4% were rented.
Pools go to the sewer
The Manly Development Control Plan 2013 says every swimming pool and spa must be connected to the sewerage system.
Two conservation areas
The same plan has special controls for the Manly Town Centre Heritage Conservation Area, including The Corso, and the Pittwater Road Conservation Area.
A lagoon catchment
Manly Lagoon is one of four coastal lagoons on the Northern Beaches that open and close to the sea. Council has a flood study (2013) and a risk management plan (2018) for it.
Pool and spa plumbing
Under the Manly plan, a pool or spa drains to the sewer, and a pool also needs its own rainwater tank, big enough to top it up when needed. Both shape the plumbing for a new pool or spa. Check the current rules with Northern Beaches Council before you build. For a pool that's losing water, see pool leak detection; for the tank, rainwater tanks.
Heritage and conservation areas
Manly sits in Northern Beaches Council's Manly Ward, and planning here still follows the Manly Local Environmental Plan 2013 and Manly DCP 2013. If your building is in the Town Centre or Pittwater Road conservation area, ask Council what needs approval before external work such as new downpipes or a stormwater line across the front.
Roots from a Council tree
Northern Beaches Council says wear and tear on sewer and stormwater pipes is the landowner's to fix, including clearing chokes, and that clearing roots from a pipe is not a repair. If a Council tree is blamed, it wants evidence before any repair starts: a plumber's report on pipe type, age and condition, a plan of your sewer marking the blockage, camera footage showing root ingress, and Sydney Water's sewer service plan.
Where a repair can't be done without removing or badly damaging a Council tree, and there's no alternative such as relining, re-routing or directional boring, Council will consider removing it. Owning the tree doesn't make Council automatically liable.
Flash flooding
Council says flash floods come when heavy rain overtops creeks or the stormwater network runs out of capacity; they arrive with little warning and recede fairly quickly. Lagoon flooding is different: after heavy rain or an ocean storm surge, the lagoon rises and spills onto the low-lying land around it. Council also has a Manly to Seaforth flood study (2019). For drainage on your block, see stormwater or blocked drains in Sydney.
What we would do
If roots from a street tree keep blocking your sewer, stop paying for clearing alone. Get camera footage, a plumber's report on the pipe's type, age and condition, and a plan of your sewer showing the blockage, and send them to Northern Beaches Council before any repair. That's exactly what Council asks for. Then we'll match you with a drain specialist who can put that evidence together.
