What are the advantages and disadvantages of having a water storage tank on a decked platform in the roof of a building?

Advantages:
*Space saving as ground space is not used
*Pressure, as its height ensures that every part of the house gets good pressured water at their tap
*Cheaper to install, than the other stand-alone type

Disadvantages
*Accessibility could be a problem
*If there is a leak, it could trickle down the walls or even into the rooms/compartments. If the Tank should burst, na big "kasali" be that!
*Piping is likely to be conduit/embedded and as such, difficult to repair, incase of a leak/fault/breakage
*May affect the aesthetics of the roof/building


Others can add their own opinion.

They tend to become eye sore with mould and algae growth over time.

Thank you sir.

I pointed these out to the guy and he said that the place would be tiled and they would use coal-tar to fill up any space.

Thanks for the reply.

Obviously, the disadvantages outweigh the advantages.

Yes all nice and neat in the beginning when everything is new but will he go up there to inspect and do proactive maintenance?

Most don't and that side of the house walls eventually grow algae.

There's one picture floating around here of an extreme one that is near collapse.

Out of sight = out of mind.

Rain rain go away, come back another day

I learned from this great properties section that when you use a mix ratio of 1:6 to get mortar for block setting.
It means 1 bag of cement to 12 headpan of sand.
Is there a way one could get to know the tonnage of that 12 headpan of sand?

Advantage
1.lower cost of platform, since it will placed on a decked part of the house which will not require the normal steel platform

2.lower cost of piping water from the tank to various part of the house

Disadvantages
1. Limited head (pressure) especially for higher building, the building at the top floor may lack the necessary height to provide pressure.

2 structural failure of building when not properly done. Since water in the tank will add considerable amount of load to the structural members that support it (slab, beams, columns and footing). If these members are not adequately design to carried the load, there may be excessive settlement or total collapsed of that part which may also affect other part of the building.

3. It impaired esthetics: having a big tank on top of the house may not really be good to the beauty of the house. This tanks may also lick to the floor there by causing paint to fall off etc.

4. It also limit the capacity of such tanks since the capacity will depend on the structural integrity of supporting structural members

This is what I hope to use. I hope to find an artisan that can create a circular one. Won't be this high as it's a bungalow.

is this cheaper than the concrete type? Saw one on a client site look solid

twinskenny:

It shouldn't be cheaper than concrete but it sure looks more befitting.

Brabus is teaching me to not "think of cost but value"

It's also secure because it won't be easy to access to pour nefarious chemicals in it and make everybody fall asleep in the compound. They they'll blame it on Juju after the robbers leave.

The free standing steel overhead tank is the best over a long period of time.

Little maintenance cost
You will get adequate pressure
Capacity is high and you don't need to worry about your building

EgunMogaji:
Some additional ideas to the ones that I shared previously and please none of the US/UK vs Nigeria stuff. It's getting old. If it can survive the harsher weather/temps in US then it can survive in Nigeria if the proper materials are used.

Oga EgunMogaji thank you for posting those pictures.. I would have commented but I think Nairaland Admin are trying to chase me out of here.. every message I write nowadays, even if the message just says "Hello" I get banned... you I may not be here too along anymore.

But that window burglary is the format approved by New York Govt to be used here. And on the side you can even have a form of lock that can be locked from the inside... padlocks are not allowed because when fire starts everyone goes into "Panick" mode that you will always forget the key to the padlocks. I wish this can be made for common man in Nigeria as this is far safer than those we have now.

Yes, there is a way... All you need to know is the density of the sand that you are using, the physical dimensions of the bucket or head pan used for the mix.

By following this simple procedure.
Get the diameter of the head pan or bucket
Get the height of headpan or bucket
Calculate the volume using nhd2/4
From the density, p=m/v... Get the m(mass)
Finally divide the mass in kg by 1000 to get the tonnage

A big no no, no one should ever try it,you will live to regret it.

How is this one better, in terms of "aesthetics" than the overhead concrete one?

This is even uglier, wastes "ground" space and the "stands" liable to rust and therefore collapse earlier, that the overhead concrete type.
It is also costlier.
Pressure is dependent on "Height above ground", (or exit of tap) so for same height, Pressure is same, whether stand alone or not
Capacity is a function of size of tank and[b] you will have same capacity[/b], if you use same tank size, irrespective of whether it is stand alone or not.
I agree that capacity translates to "weight" but you will also agree that "achievable capacity/weight" is also a factor of the "Iron stands" used in a stand alone type otherwise, it will crumble. If you make good Iron stands, then you can equally make a strong concrete deck (with appropriate columns/beams) along with your building

Anyway, each man to his own.

Surprise!
I used to think you were the "Chief Banner" around here?

Admin should relax o because l dont see any reason for "muscle flexing" around here.


I will make this Screen, Hajj ...and will post the pictures here for all to see.
Its easy to add that KeyLock to it. Even a Padlock sef though it wont look fine.

The thing about Key is such situation Sir, is to "make our families go through a fire/emergency drills, at least twice in a year.
Let even the smallest member of the family know EXACTLY what to do, in case of an emergency.

My children know where/what corner of the house to run to, if they hear gunshots ..or Thief! thief!!
We even have a song for it (Lie down, face side, in the Red corner if you can make it there).
'Security Door' Key never leaves a particular place in the house.
Extinguishers and fire blanket must never be removed but l check them whenever l can.

I agree, panic can make the brain numb.... only previous practice can give someone a fighting chance

Cost is the only advantage that tank placed on decked platform have over overhead tanks stand.

Space is not really a problem because the stand can be sited on a 2.1m c 2.1m plan.

The location can be at the back of the house closer to underground water source (bore hole). Most people consider the one mounted on top of the house ugly because it affect the floor of the roofing because some part of the roofing will need to be opened for such deck.

Steel structures carrying axial gravity land have more capacity than reinforced concrete structure. Such a steel platform can easily be built to carry a very large load than can't be achieved with a decked platform.

Pressure(head) increase with height, a tank on a decked platform will supply water to the upper part of the house of two storey building of say 3m per floor at a much lower head(pressure) than an over head tank of 8m high.

Hello guys...Please anyone know how much a 4" Galvanized pipe cost now? I need to build a scaffolding for two water tank (2500 each).

Thanks

Beauty is in the eyes of the beholder and some of us made the necessary sacrifices and bought enough land that we don't have to worry about fitting something with a 8X8 feet footprint

Costlier? Of course, I said so earlier. This is why I go to work every morning. So that I have money to buy what I want and not what I see

Yes, to each his own. I've made my choice and I am secure in the selection.

I am going to throw another design into the mix. I will attach the picture in the morning it's a freestanding concrete water stand.

The other idea that I'm considering is to have the burglary proof system be decorative steel shutters on the outside. So the windows won't even be accessible from the outside.

In my design, the Kitchen, the most common source of fire in the house, is on the outside wall and doesn't bother any bedrooms. Moreover I have another safety exit in terms of a 500 square foot courtyard right smack in the middle.

I'm just glad that folk are starting to think about these safety stuff. One can stop the underworld without sacrificing safety.

I'll show an example soon.

Here are some wild and outlandish window ideas that I have. It's not for everybody but I hope it can motivate others to think outside the box.

Definition of insanity is doing things the same way and expecting different results. The thieves in Nigeria probably knows the regular standard doors and windows and who to bypass them. Challenge them by doing things different so that it confuses and destabilizes them even if for a minute while you get out your trusty and well sharpened machete

Some of this might not work for all especially if you depend on windows for source of light and breeze in totality. I have a gaping hoel in the nodded of my house of that.

The last is the EWT that I sport wood for

Remember that the highest walls and strongest windows might not deter the most hardened criminal element, what you are trying to do is cause the robber to think of reasons to attempt on yours when he can go on to easier targets that poses lesser hassle.
