Just be aware that sub standard practices are often still compliant due to the lax rainwater harvesting regulations but some will void the manufacturer's warranty. Unfortunately, manufacturer's installation recommendations are…

WA adopted the Plumbing Code of Australia (PCA) on 1 May, 2015 and has remained so since.
The PCA is Part 3 of the National Construction Code (NCC).
I can find no…

So basically it means that the Council's Permissable Site Discharge (PSD) requirement through a meshed 20mm outlet may not have been complied with and the current detention outlet could even…

Going by the photo of your unplumbed tank, I am wondering whether they have plumbed it like in the photo below? This shows a system that interconnects (loops) the infeed…

Unfortunately, council boffins who draw up these regulations often have no qualification or credible practical experience to do so as would appear to be the case here. This often results…

Hi r_13.
On Feb 16, 2019 you responded to a query/ suggestion that I made re possibly incorporating a rainwater tank with a retaining wall. Unfortunately, I have only now…

PCI is mainly for cosmetics. One of the most important final inspections that is rarely done is a CCTV forensic inspection of the stormwater and drains. This forum is littered…

It should be noted that Australian Standards are produced by Standards Australia, a non government not for profit organisation.
The NCC is a performance based document that references many AS as…

Australian Standards have no legal standing unless they have been legislated or referenced in a contract. As to what part/parts of AS 2870 applies to your contract and construction needs…

Unfortunately, it is still early days yet and the builder can say that they are proactive and waiting for movement to stabilise which is essentially correct. I would see the…

The above is absolute garbage. Heaved slabs do not settle back in their original position and the time frame is absurd.
Firstly, you need your own engineer to take slab levels…

Have you verified with the council?

Google would be your friend here. There are numerous studies concentrating on the amount of micro plastics in the food chain, the air we breathe and even the amount that…

Grey water needs to be used fairly quickly as it can't be stored for more than 24 hours.
You also need to pay attention to the laundry detergent composition before…

The builder, in my opinion and experience, is wrong. A slab also adds to a tank's height above the ground level, is he also disregarding this?
Does he also think that…

You're a surveyor yet you don't know?
The answer to life and all else is 42.

The black certainly stands out, particularly against the lighter colour. They need matching against the two clashing backgrounds. It would now be dangerous for a layperson to paint yet so…

Will they be painting those downpipes before handover?

Found the similar thread. It could be worthwhile reading through it.

Didn't you have a previous thread about this?

Spammers cannot promote/spam on the forum as much as they like. It helps the forum if spam is reported.
The spammer you responded to also spammed several other threads. Just…

Given that you have a need for both OSD and a retaining wall, have a look at the tanks in the link below. The tanks double as retaining walls and…

How high will the retaining walls be?

Many threads about this same problem.Have you done a forum search?
Pumped systems are pricey and problematic, try to cost a detention-retention system.

That would be a hard landing, a lot worse than the Iceland ones.

Most builders will charge for a variation. Ask, don't get caught out.

It's good.
I would never specify the use of flimsy SN2 pvc stormwater pipe in a charged system but it is probably included in the specs.
Not impressed with the…

You need to read the forum's terms of use before considering providing commercial information when you a member who is representing a business.
Have you considered becoming a paid advertiser…

Even IF the wall is on the boundary, the holes have been drilled into your building structure on your property.
So many disputes now about this type of situation.
