Having read the thread re the probable enforcement of pump out holding tanks in Turkey..Can I move the discussion on to the technicalities of the process?
How is it carried out? is there a rigid pipe which will be dipped into the tank by the dockside unit which sucks out the waste ? If so what diameter will it be?
I ask this as I would be able to cut a hole in the deck directly above the tank fit a short pipe directly down to a new fitting on the tank,and obviously install a screw on deck fitting . At present the tank empties by gravity when I open the seacock....we always do this when there is an English yacht astern (ONLY JOKING!!!!!!!).
Anyway....what do we need to do if we want to keep the Turks happy?
 
Normal way is to have a dedicated pump out assembly. This comprises a solid pipe which reaches almost to the bottom of the tank attached by reinforced hose to a dedicated pump out filler cap on the deckhead somewhere.

The pump out facility should have a big vacuum pump which they hold into your deckhead fitting and Robert is your mother's brother.

Make sure you know which is your diesel filler cap and your holding tank pump out cap. Confusing them could be expensive at the pump out station and even worse if your trying to siphon some fuel out of the tank :)

There is a standardised 38mm pump out deck fitting to ISO 8099 (see Vetus catalogue p 105). You have a 38mm fitting on the top of your tank and a hose connecting the two. I have had two gravity tanks made and both are fitted with the outlet directly above the outlet to the seacock so that you can rod or direct a hose to clear blockages. Neither of my tanks (in different boats) have the deck outlet fitted because there are no pumpout facilities where they operate - but they are "pump out ready" and can be "pump out enabled" very easily (Don't you love my grasp of modern vocabulary!)

Hope this helps.
 
Thanks fellas...I will modify my tank as suggested and await the proposed pump out facilities....but won't hold my breath. (metaphorically speaking )for the new legislation to be enforced.
 
Exact deck fitting specification

Does anyone know the specification for the deck fitting. I assume that the pumpout station will screw onto this or press onto this.
I would like to have this part on my boat correct by making an adapter if the thread is not right.
It seems that you have to pay for the download in order to read the standard ISO8099:2001 standard.
Is 1 1/2" bsp the standard size or 38mm... could someone who knows comment.
 
The only place I can fit tanks is in the bilges, and only small ones at that, and direct pump out from there will not be possible. The tanks I have ordered are currently being made and I am going back to Turkey in a week or so to do some work on the system. I am going to fit a pump to empty the tanks and will plumb it so that it can pump out by means of a hose passed out of the boat. It is simply not possible to use 38mm hose in the confined spaces in the bilges, so pump out stations will just have to live with a slow rate of delivery.
If I find later that a specific fitting is needed to connect to pump out stations then I will put one on the end of the hose. I am also going to fit a diverter valve so that I can pump out via an existing seacock where permitted. I consider the latter to be an essential, because it is unlikely that pump out facilities will be available everywhere.

As for adding a deck fitting with a 38mm pipe to connect to the tank's outlets between them and the pump, that can only work on my boat if the pump out stations have an airtight connection to the fitting, and good suction. The pipe routing would be far too convoluted to pass a suction tube down it, and it would still need to be sealed against air ingress.

EDIT: I am talking about Grey water tanks here, I already have black water tanks with deck pump out fittings (which have never been used), but in both cases the fittings are directly above tanks via a short straight hose, and a rigid pump out tube would pass straight down to the bottom of the tank.

The Vetus fitting is described as having a 1 1/2" BSP thread. The Lesan catalogue describes two pump out sytems - "Probe" and "Screw" and suggests that both use the same attachment.

Guess you really need to see what pump out system they are using in Turkey. Lee Sanitation is probably the better source of information on fittings as they are the experts.

This may be the $64K question... will it be the same system in all places?

I am not in any great rush to modify the tank...will wait & see what the situation is next spring.

Thanks to everybodyfor all the info &advice.
 
Holding and Black watertanks 2

I think the solution is to fit a water treatment system inside the boat - A centrifuge to remove solid matter and compress it and also have a solid biological toilet sytem which you can mix the solids with and turn into compost at the end of the year . As for the water residue this this can be treated by evaporation under vacuum using the heat from the engine . Concentrate resulting will only require a small tank for disposal - possibly a bottle dropped once a week in the nearest bin
 
This will be the cheap option then, that doesn't mean a whole load of work and alterations to the boat!
Seems a lot of money for a couple of months cruising - if you staying in Turkey for ever maybe. For most liveraboards (meaning those who actually live on board 365 day a year not just for the summer or winter) this is an incredibly expensive idea.
 
For liveaboards in a marina, there is a cheap option. Install a small holding tank to take grey water. When it needs emptying put a big plastic jerrycan onto a folding trolley on the pontoon, and pump the tank contents via a hosepipe. Wheel the jerrycan to the nearest safe disposal facility (AKA the nearest toilet block). Cheaper alternative, just divert your basin waste directly to the jerrycan, but then you have to lug it up the companionway.

Really marinas need to do what caravan sites do in the uk, and install a dedicated drainage point for do it yourself grey water disposal.

EDIT: Caravanners use the things for waste water disposal. http://www.aquaroll.com/English/wastemaster.html

The only Marina with a pump out service we found this summer when cruising in Greece and Turkey was at Zea Piraeus.
The system was installed on all pontoons and the staff connected to a vacuum connector at the electric/water stand and then ran a pipe to the boat.They had a selection of fittings which seemed to fit all sizes of outlet.
We had to use gravity emptying for all the season apart from Zea.Yes WAY off shore.or at least well past the sewage outlet from the town
 
All well and good to say 'there is a cheap option. Install a small holding tank to take grey water.

Wheel the jerrycan to the nearest safe disposal facility (AKA the nearest toilet block)'.

I, like many would like to cruise this area of Turkey, but there is no way I could another holding tank into the boat - along with an additional electric pump to transfer it from the sinks, additional Y valves as well as new piping add into this cost of the materials. Then think about loosing a 250ltr fresh water tank (much more important to me than a bit of sh*t over the side! sorry for that but you need to be practical about these things) and ripping half the boat apart to fit it then put it all back together again, as we live aboard full time this would mean hotel accommodation for at least a week due it being impossible to live in this sort of mess.

Nothing practical about this law, unless you have a big boat, a new boat with a grey water tank fitted, or room to fit a new 'king huge black water tank with new pumps and plumbing.

I do agree with the what they are trying to achieve, but they should put their own house in order first, this must include all waste water from any housing, shop, taverna industry, etc, etc, etc, new or old and then ensure that every Turkish boat afloat has a black water tank fitted and is obeying the law. Until that happens they are taking the piss.

Reckon you are being a bit O.T.T about this.. There would be no need to "rip the boat apart" to fit a small grey water holding tank.And why would you want to loose( or even lose ) your 250 L fresh water tank to fit it.
I think that Norman E's suggestion warrants consideration.. A small tank under the sink with an outlet -pump-and hose fitting which could be emptied at the appropriate places.A flexible type tank in the bilge under the galley is also a possibility.
This might be sufficient to satisfy any regs. and keep the Turkish bods happy.
I agree with you about the waste water etc from non-yachties especially the large Gulet armada which seems to live in these parts and also with you that this law is not practical,but it is their country and they make the laws,so we will just have to get on with it.
Is there a company which makes holding tanks on the Turkish Stock market? Might be worth a punt!!!
 
Depends on what you class as small. Realistically anything less than 25-30lt isn't worth installing. Hereby lies the problem - I don't have the room to fit it. Under the Galley sinks is the 2" Whale bilge pump, no other accessible (for a tank/jerry can) space in the galley, or in the saloon. No other place to place a tank inside the boat due the 1980s IOR hull design.

Bilges won't take a 10lt can of water due to the web placements, anyway they are for wine! which as we all know is most important. So getting back to post, in order to fit a grey water tank I would need to loose a fresh water tank. No go there then!

But, as I have said on the other thread - watch this space until April when we all might have more idea of what's going to be happening.
 
With all these new tanks / pipes / joints / fittings / hot weather, going to be a lot of stinky boats about in turkey next year, might give it a miss.
