Do we need permit from HDB to install Fish Tank ?

[minsmarine]

I was reading at another form and happen to understand that larger tank ( in term of weight > 600Kg ) need to get permit from HDB.

I just calculated simple way let say 150x60x60 tank (5'x2'x2') tank just water alon is already 540Kg. Does it make anysence ?

However, there was clause saying that "FOUR LEGGED RACK OR CABINET", so I believe most of us here need no permit from HDB.

Just wonder any reefer here exceeded limit (600Kg) and cabinet wit four legged.

Or your guys cabinet come with 6 or more legged ?

My cabinet is flat on the floor and my fish tank >600kg

[ryz]

flat on the floor translates to a single legged aquarium? :lol:

Yup a single big and long leg...

[minsmarine]

Bigger than elephant leg than, just wonder any reerer here has >400 kg and 4 legs ?

Actually the position of the tank will be more of a concern, e.g. don't put a heavy tank at the balcony. The balcony might give way...

Yes, legally you will be required to get the permit. I think the max permitted size without the permit is 4ft x 1.5ft x 1.5ft or something like that (it's in their website)

Even if you put your tank on a purpose built cabinate.

However, the permit application is relatively painless. Just submit your tank plan with your floor plan marking out where you want to position the tank. I got a positive reply in around 3 weeks.

What is ur tank size?

Mine is already there for the past year and if apply, all of some funny reasons, the answer is negative, then wat? I have to remove the whole, is it?

Too bad last year my designer never apply for me... nevermind lah. Anyway, the HDB officer come to my house before, and saw the tank. He did not said anything, except that he commented that the fish tank is nice...

Hoo Hoo, if HDB doesn't approved vincegoh's tank, than we are going to see more on market place Wish HDB does not approve so we could get cheap cheap second hand equipments , corals , fish etc (....... JUST KIDDING OK ) )

You never know,one of these day it may happen(touch wood)

Actually to date how many reefers with tank 5 ft and above apply for permit?

[shiraz]

as long as your tank is near a wall, which in turn would be near a horizontal support beam, it would be fine..

u actually can put your tank at the balcony.. provided u don't live in an old flat and the balcony was 'added on' to the flat.. the balcony in this case is a cantilever structure...not able to support much weight.. a king size bed with 2 ppl sleeping on it is about the most it can take..

Well, HDB design loading is 1.5kN/m2 for uniform distributed load (a patch loading) and 1.4kN for concentrated load (point loading).

Do your own maths

Geez, me maths graduate but gave back all the formula to the lecture 16 years ago.

And I don't think all of us here are maths grad.

Appreciate what it excetly mean

Well, I suppose it depends on the type of stand u r using.

For example, if you are having a 5' x 2' x 2.5' tank on a 4 legged stand.

Convert to metric unit will be 1.524m x 0.6096m x 0.762m.

Thus, volume = 0.708m3

AS we know the density of water is 1000kg/m3, therefore the total weight of the tank is 708kg.

Weight per leg (of the stand) = 708/4kg = 177kg = 1.7kN

HDB regulation is 1.4kN, hence not good!

Thus, to overcome this, use a cabinet that is seating on continuous "stand". Example for my case, it is the footprint of the tank. This will satisfy the above criteria.

As for the patch loading, if the loaded area is not near to other heavy stuff, the combined floor area (within the beams or walls) should be able to satisfy the 1.5kN/m2.

Wooo great info. Thank lot.

BTW, I understand 1L of nature water is 1Kg. Actually same as your figure Cheer

[minsmarine]

Wait a minute, we are not considering the sump yet, so mean for 5 footer, than it lot above 1.5KN.

Ya, the calculation have not take the sump into consideration yet. But usually point load govern, not patch load 'cause e.g. if the floor area where u place ur tank is confined with an area of 3m x 3m = 9m2 (within beams or structural walls like bomb shelter), that means total load for the area must not exceed 1.5 x 9 = 13.5kN (where the 5' tank weight is 7kN + sump).

So usually quite safe.

I see, thank for unlightening me.
