No open ended svp's, in high rise buildings

[Plouasne]

Just wondering what other posters think about the idea of non vented soil stacks, the tallest building in Dubai is supposed to be like this, I believe that its an Australian "idea", stub stacks off the main stack with an AAV stuck on top of it and inside an enlarged section of pipe, a "bladder" to take up the forward compression of air

The idea is that there is no roof penetration, which could leak rain water into the building

Apart from the looks of the things, (I saw some photos of them fitted in Hong Kong) bloody ugly, I am wondering about the build up of drain smells, etc, because the drains are not ventilated in any way

Another snippet of information, I came across was the enterprising Indian drivers of the septic tank emptying tankers, got fed up with waiting to dump the load at the local sewerage works, so started to dump the loads down the local storm drains, which wasn't found out until the rains came then a few hundred thousand litres of raw sewerage got washed out and onto the beaches

The sewage thing happened back in January,so hopefully sorted out now,it must have cost them millions to clear up as there was thousands of tons dumped,you could say the biggest dump anyone had seen


And they were still charging 5/7 star prices to stay out there

Not funny for the marine life and coral reefs though and e-coly flying about


Would add in the interests of racisam,it was not only indian drivers but philipino,yemini and other nationalities also

Its a shame that they spoiled it I was out there in '65, only 5 miles of black top road then, I was with the RE's doing a badger distillation plant, at a place called Mirfa, miles and miles of sand one side and the Persian gulf the other, and bugger all else apart from a Trucial Oman Scouts (army) tented camp

Thats where I learned to walk (well run like the clappers) on water, being chased by a bloody great shark does tend to make you move a bit faster than normal

Respest Plouasne,you were one of the pioneers
My father worked in the oil construction bussiness,was in the middle east about same time,Das island,Emerates ,ended up starting his own construction firm in Bahrain, in early 70's,went out there for 4 years as a teenager,then came back,as you know,you have to have an arab bussiness partner and think my dad picked wrong one but he did ok, then did a few years in saudi in the early eighties working.
What transportation did you use to get out there in the sixties ?
Ps I was always corrected out there and told to name it the Arabian gulf...My first experiance of political correctness )

Bit of a long story really Puddle, but to cut it short, after doing an apprenticeship and a few year on the tools, plus being in the TA, I joined up was in the Royal Engineers
For the Trucial Oman Scouts, I was up country in Aden at the time, flown by the RAF to Bahrain first for a stopover then to Sharjah, then in the back of a 3 toner for 5 hours across the dessert
The aircraft were Avro Argosy twin tail boom, on the way back the flyboys forgot to collect the sandwiches so did a diversion to a camp where there was a bit of a "do" going on in the Oman and a lot of the boys there wore beige berets, if you get my drift, and to avoid any nasty incoming stuff, the pilots when airborne went straight up vertically, for the first 5000 feet, then gave us a sightseeing trip along the coast, pointing out the sharks in the water, and there were hundreds of them just off the coast

many soil stack instalation types ,from 2 pipe, single pipe,with anti syphon pipework,garche,vacum ,it goes on and on depending on country you live in pakistan has the most stringent sanitary laws on paper but some of worst in practice.think how lucky we are in gb

 

[Plouasne]

Ahhhhhhhhhhhhg,

The Garchy system, I did that on the Barbican, and a few other places

we should form the last of the plumbers who new the dinasours

Not all the old dogs are dead yet, what about 4" lead soil stacks

I remembered a tale from way back in '58, a Shoucksmiths (sp) apprentice plumber came into the tech one day saying "I'm working on a new type of gutter", what is it we all asked, "plastic" he replied, "cannot half earn a bomb on bonus" (because the bonus was still priced on cast iron guttering) no f***ing good 'cos it don't hold water"

Dave, just to give you a little bit of my work experience,nothing much out of the ordinary

12" Cast Iron drainage for the main rainwater drain, Jumbo jet servicing hangar Heathrow all hot poured lead joints, in the ground,
12" Cast Iron Tyton jointed fire main Enfield, (where Taylor Woodrow design engineer, forgot or didn't know about "Thrust Blocks" on the change of direction)
4" copper soil stacks luxury flats next door to Madam Tausauds (sp),
4" polythene chemical soil stacks, just across the road from the other job, spelter brazing loose flanges on 6" copper Old Bailey,
4" PVC solvent welding water mains,
4" Cast Iron caulked lead water mains,
6" cast Iron sewerage sludge main,
apart from the rainwater drain, copper, and polythene soil stacks , all the other cast iron was tested to 200psi for an hour,
I have also done 150mm Blue Poly water main, flat plate fusion but welding, and electro-welding the branches, 63mm yellow gas, but welding and hot iron saddle joint welding
I have also done a spell in a design office as a trainee draughtsman, but could not stick being cooped up all day long

And just for the hell of it raised 28mm and 40mm copper stop ends out of scrap copper tube, just to show the French that the English were better than they were, the French way of a stop end was either a dog rough purse hard solder end or a piece of copper hard soldered over the end of the tube and ground to shape

Yeah, but other than that what have you done !!

You don't really want to know do you ??, a not very civil, civil serpent, "mercenary" for HMG amongst other things

 

[HTB]

I've done ground runs on an Argosy if that helps, it jumbed the chocks when we put all 4 to max (which we shouldn't have done but it was fun). It was twin boomed with 4 Dart engines which had a vey high pitched whine thus earning it the nick name "the whistleing wheelbarrow".

 

[Plouasne]

Did you ever hear about the accident between a VC10 and a dumper??

Brize Norton, back in '66, 1 Troop 50 Field Squadron Royal Engineers were tasked with removing, parts of the bomb dumps at the airfield, and the route involved crossing the runway, temporary crossing lights had been set up on the one way only crossing, but this idiot decided that it was quicker to go in the reverse direction and was crossing the runway, just has a VC10 came in to land, the result was a tail dragging on the runway, when the pilot applied more power to abort the landing

the good old daysssssssssssssss i remember them well

The Installation you saw in Dubai is an engineered system using a Positive Air Pressure Attenuator (PAPA) in conjunction with AAV's The PAPA was developed after extensive research into positive an negative transient pressures in SWV stacks at Heriot Watt University The practical application of this research is a good example of how traditional plumbing methods can be improved by proper scientific research.
