Hi All,
I am looking for a septic supplier to supply a tank to Dungarvan, Co. Waterford. I tried using the septic tank pricing thing on the website but no one got back to me. Not a whole pile of septic tank suppliers coming up on google either! So I'll throw it out there, anybody have any contacts for me?
Cheers,
Joe |

Hi Joe,
I'll drop you a call over next day or so and explain the little issues surrounding EN12566-1 and the certification of Septic Tanks.

Hi Thomas,
Different People have different views on which material is best for a septic tank.
Obviously the suppliers of plastic / fiberglass tanks will tell you they are better than a concrete tank; and suppliers of concrete tanks the oppositte.
One of the key things to remember with regards to a new septic tank, is the installation of the tank is extremely important.
Poor installation with any tank will will result in problems.
If you choose a plastic tank/fibreglass tank. Then lean mix concrete back fill is advisable.
More so if there is the possibility of an elevated water table in your area.
A sound firm footing or base is needed for both types of tank.
Remember when the tank is full that is a significant weight.
My own preference are concrete precast tanks. One single unit that does not require joining of elements below the liquid level.
I can give you some contacts if you want?

Guys. The Balmoral HydroClear STP is CE marked to 97% pollutant removal, is manufactured from polyethylene and has no moving parts to break down or need replaced.
Some answers to queries:
1. Whether any tank requires to be backfilled with concrete depends: A] on the level of the water table on site and B] a concrete base stabilises the tank from 'sinking' over a period of time.
2. Someone said they requested a quotation but no one got back to them - I received no request so maybe it was posted in the 'wrong' area; contact me and I'll price accordingly.

Hi All,
Perhaps I can shed some light on some of the queries.
A) I totally agree with all the comments made by Ronan O'Halloran. Good solid advice. If I may just add a comment in relation to the back fill material around plastic/fibreglass tanks. When you are installing and back filling around the tanks make sure you follow the manufacturer’s instructions. Some manufacturers recommend 20/30N concrete and others recommend leanmix standard. My own preference is as per Ronans, Precast Concrete Septic Tank that is EN12566-1 Certified.
B) Henry of Balmoral tanks has mentioned the Hydroclear sewage treatment plant. This is a seconday wastewater treatment unit and NOT a septic tank. I don’t know if Balmoral have an EN12566-1 certified septic tank. Perhaps Henry can let us know?
One other thing to keep in mind is that all secondary wastewater treatment units that are to be installed in IRL need to be EN12566-3 certified AND have been tested in accordance with EPA CoP which means the influent testing parameters has to be between 300/500mg/l. In short don’t buy a secondary wastewater unit unless you have a cover letter stating that it has been tested and is in compliance with EPA CoP standards.
Perhaps Henry can also tell us if the Hydroclear STP has been tested to the correct influent range as stated above?
C) The reason that the request a quotation was not forwarded to the septic tank companies is very simple. SiteAssessor.com is no longer forwarding quotation requests to companies that do not comply with the various EN12566 and CoP regulations. SiteAssessor.com is currently compiling a list of units suitable for use in Irl so if you know of any then please let them know info@siteassessor.com and they will list them.
I hope this helps.

Hi Joesph and others. The new regs are very clear on Septic tanks. They have to be EN12566-1 certified. Killarney Plastics Tricel P6 septic is EN12566-1 certified and will be available in about 3 weeks. Its worth waiting, as you may be asked to remove any other tank put in.
Tricel also have a range of wastewater treatment systems, P6, P9, P12 etc all certified to EN12566-3.
look at the site for details of the new septic tanks www.tricel.ie |

Hi Thomas / Ronan
Yes you will get different views on the materials used in manufacturing tanks. Concrete tanks tend to be 100mm thick to give them the strength required to hold wastewater and not break.
GRP tanks like the Tricel tanks only need to be 5mm thick as the materials are so much stronger. So neither is better or worse, just that the GRP tanks are more durable and easier to get into sites, especially wet ones.
When you test to to EN12566-3 (for a wastewater treatment system) or EN12566-1 for a Septic tank, the test-house test for efficiency, structural strength and watertightness. Have a look at the cert here
http://www.tricel.ie/downloads/european_certification_sewage_treatment.pdf
There is a list of all 7 of the current Irish certified systems (not companies) at

Hi All,
For future readers I'd like to clarify a point that Con made in a previous posting ref Septic Tank installation: "It’s worth waiting, as you may be asked to remove any other tank put in."
In my opinion this is not actually correct. If your Septic Tank is not En12566-1 certified then dont worry so long as the installation complies with part H of the TGD.
This is what Part H of the Technical Guidance Document states on Page 3
In a nut Shell if your house has commenced after June 1st 2011 then I would install an En 12566-1 Certified tank (where a septic tank has been specified)
BUT
If the construction of your house has taken place before May 31 2011 OR If you have been granted planning permission before May 31 May 2011 and the house is substantially complete before May 2012 then a septic tank that is not EN 12566-1 certified will be sufficient.
The point above is only a point of clarification.
I would like to make the final point in that if you are going to spend your hard earned money then make sure the tank you purchase is EN 12566-1 certified. At least you know the tank has gone through a testing process and is fit for purpose in an IRL context.
Con has listed a website that is in Germany called PIA. This test house has listed Irish WWTU units on their website that have gone through their test house and are suitable for use in Ireland. It is important to note that there are also other European wwtu systems that have been tested in PIA and are currently for sale in Ireland but have not yet been listed on the PIA website.
Also as far as I know PIA is only one of a few testing houses. I know from talking to the lads in SiteAssessor.com they have been contacted by a few WWTU companies who have not been tested in PIA but have the valid EN12566-1&3 certs. SiteAssessor.com will be listing the new certs over the next few weeks. If you have a valid cert then send it into the lads info@siteassessor.com and get them to list it on the website.
If I am incorrect about any of the above details then please let me and other viewers know.
Thanks
Tim |

Hi Tim, thanks
FYI: PIA gmbh are updating their site daily, and there is another Septic tank tested & certified to EN12566-1 on the site from today. This is suitable for Ireland.
I agreed that PIA are not the only test house (sorry if I was misleading) but we know for sure that the systems tested by PIA meet the Irish standards if they are on their Irish certs list. Unless other test houses follow PIA, how can we be sure the systems pass the EN12566 (1 & 3). Systems must meet both EN12566-3 and the Irish standards to comply with Building regs part H going forward.
Regarding valid certs, the most importing thing is that the EN certificates are in fact valid and can be validated.
Most people in Kerry & Cork remember the Bio company that said it had the European cert, but it was in fact a cert for "the thread strength for the sole of a shoe" and nothing to do with WWTS. |

Hi Con and others,
The advice you have given is excellent. People reading this thread have to realise just because the tank they are purchasing is EN12566-(1 or3) certified it does not mean that it is suitable for use in Ireland. As one staff member of the Kerry Site Assessment Unit put it "If a person wanted they could get a wheely bin certified but that does not mean it is suitable for use in Irl as a WWTU".
So Con is correct.... make sure that the unit you are purchasing has an "EN certificate and are in fact valid and can be validated."
On a separate note Con perhaps you can answer me a question or two. When it comes to septic tanks and calculating the nominal capacity would I be correct in saying that the min requirment for Irl is a septic tank with a nominal capacity of 2.6cu.m (4PE) and anything less is unsuitable for use in Irl.
The EN12566-1 certs which list the results only record whole number increments for nominal capacity. As you can see from the two certs that are listed the nomincal capactity is 3cu.m whcih only equates to 6PE. What would happen if a Septic tank had a nominal capactiy of 3.2cu.m would the testing houses only record this as 3cu.m and in turn would this not be misleading both the homeowners and engineers???
Would it not make more sence to list the septic tanks nominal capacity without rounding down or better again would it not make more sence to list the septic tanks population equivalent and take all the hard work out of it for us homeowners?
thx and sorry about all the questions but you as as a company with two certified tanks (Killarney Plastics Tricel) are probably the best man to ask.

Hi Tim / all
Reference the sizing of Septic Tanks in Ireland we must look to the EN12566-1 standard.
Page 4
Part 3: Nominal capacity (NC) is the numerical designation of the volume of a septic tank, expressed as an integer in cubic meters.
Part 4: Septic tanks are classified by preferred sizes (NC) on the basis of a minimum nominal capacity of 2m3 with nominal capacity differences of 1m3 between two consecutive sizes.
In summary: The smallest Septic Tank suitable for Ireland will be a 3000 litre Septic tank.
Note: As capacity can only increase by a full M3, you will have to round up the systems to the nearest m3, ie
P6 (3000 litres),
P13 (4000 litres),
P20 (5000 litres),
P26 (6000 litres) etc. |
