Potable Water Approval in the GCC — What the Certificates Do and Do Not Buy You

Potable water pipe certification for the GCC: the claim nobody can source

Somewhere in almost every plastic pipe quotation sent into Saudi Arabia or the UAE there is a sentence like this: “Our material is WRAS approved, so it is accepted for potable water in the Gulf.”

We searched for the document that would make that sentence true. We could not find it.

This article ends with a clear statement of what WRAS, NSF/ANSI 61, ACS and KTW/DVGW actually are in law, what our plant holds, and why the leap from “we hold X” to “therefore we are approved in Riyadh” has no published basis we could locate on any official source. Our broader GCC import, documentation and SASO conformity picture sits on our Middle East market page — this piece deals only with the drinking-water-contact question that page deliberately left open.

United Kingdom: the law names no scheme at all

Buyers treat these four as interchangeable badges meaning “safe for drinking water.” They are not interchangeable, and two are not even legally mandatory at home. Start with the UK, the one quoted most often at GCC buyers.

The legal duty in England and Wales comes from the Water Supply (Water Fittings) Regulations 1999. Schedule 2, paragraph 2 states that “no material or substance … which causes or is likely to cause contamination of water shall be used in the construction, installation, renewal, repair or replacement of any water fitting” (UK Statutory Instrument 1999/1148, Schedule 2, legislation.gov.uk). Note what is absent: no approval scheme is named. The law bans a result, not a missing certificate.

Regulation 4 sets the quality duty — “Every water fitting shall–(a) be of an appropriate quality and standard; and (b) be suitable for the circumstances in which it is used” — and lists the conformance routes, including harmonised standards, British Standards or equivalent national specifications of an EEA state, or a specification approved by the regulator (UK SI 1999/1148, Regulation 4, legislation.gov.uk).

So the correct statement is: WRAS Approval is a voluntary scheme and one route among several to demonstrate Regulation 4 compliance. The regulations are mandatory; the scheme is not. Competing schemes market themselves as alternative Regulation 4 routes, but we are not going to list them as recognised on their operators’ say-so: we could not find a regulator-side document — from the Drinking Water Inspectorate or elsewhere in government — publishing an official list of accepted schemes, so we have no citable basis for naming any of them. Applying our own rule from further down this page, a scheme operator confirming that its own scheme counts is the same class of evidence as WRAS confirming WRAS counts. What is verified here is only what Regulation 4 itself says: the conformance routes are the ones listed in the regulation, and no scheme is named in law.

A sourcing note: we tried to quote WRAS’s own description of its approval scope from wrasapprovals.co.uk and got HTTP 403. The legal status conclusion does not depend on that page — it comes straight from legislation.gov.uk — but take any precise WRAS scope statement from WRAS directly, not from a supplier’s marketing.

United States: NSF/ANSI 61 has a narrower scope than people think

NSF/ANSI 61 establishes minimum health-effects requirements for contaminants imparted to drinking water from products, components and materials in drinking water systems. Its scope covers protective barrier materials such as cements, paints and coatings; joining and sealing materials such as gaskets, adhesives and lubricants; mechanical devices including water meters, valves and filters; and pipes, hoses and fittings (NSF/ANSI 61 standard record, ANSI Webstore).

The exclusions catch specifiers out. NSF/ANSI 61 explicitly does not establish performance, taste and odour, or microbial growth support requirements, and point-of-use and point-of-entry treatment devices are outside its scope (NSF/ANSI 61 scope statement, ANSI Webstore). It is a leaching-and-health-effects document — not a pressure rating, not a service-life statement, not a taste-and-odour clearance.

On legal force: it is a voluntary consensus standard, not federal law in itself. Enforceability comes from state-level adoption and from Safe Drinking Water Act section 1417, as amended by the Reduction of Lead in Drinking Water Act of 2011, which defines “lead free” as a weighted average of not more than 0.25% lead; the US EPA notes eight ANSI-accredited third-party certification bodies certify to that requirement (US EPA, lead-free certification marks guidance for pipes, fittings, fixtures, solder and flux; the page has moved, so search the EPA site rather than following an old link). We also received HTTP 403 from NSF’s own knowledge-library page, so the scope wording above comes from the ANSI Webstore standard record, an equally authoritative primary source.

France: ACS is genuinely mandatory — and is being replaced right now

France is the one case here where the approval itself is legally defined and mandatory. Article 2 of the Arrêté du 25 juin 2020 defines the ACS (Attestation de Conformité Sanitaire) as the proof of the sanitary harmlessness of a material or product concerning drinking water, delivered by a laboratory authorised by the health minister, with laboratories accredited under article R.1321-52 of the Code de la santé publique (Légifrance, Arrêté du 25 juin 2020). It is issued by a state-authorised laboratory, not by a private certifier running a scheme of its own design.

Now read that citation critically, because it does not cover our products. That arrêté is scoped to metallic materials and products in contact with water intended for human consumption. Plastics — PPR, HDPE, UPVC, PVC — fall outside its scope and are dealt with by a separate French text. So the paragraph above is a correct description of what an ACS is and who may issue one, but it is not the legal basis for an ACS on a plastic pipe, and we will not present it as one. We looked for the official source applicable to plastic and organic materials and did not manage to open and verify it ourselves, so we publish no clause or article number for it here. If your specification names ACS on a plastic pipe or fitting, confirm the applicable text and its current status with a health-ministry-authorised laboratory or your certification body. Do not accept the metallic-materials arrêté as the answer from any supplier — including us.

If your specification predates 2026 and names ACS, the regime is changing. The framework is being replaced by the harmonised EU regime under Drinking Water Directive 2020/2184 Article 11. Décret n° 2026-80 of 11 February 2026 restructures it: general entry into force 1 January 2027, conformity-assessment-body provisions in force the day after publication, and compliance moving to accredited bodies under EU Delegated Regulation 2024/370 with European positive lists (Légifrance, Décret n° 2026-80 du 11 février 2026).

Frequently misreported: existing ACS certificates are not immediately void. The décret provides that the attestations “sont valables jusqu’au 31 décembre 2032” — valid until 31 December 2032 — but only where all three of its conditions are met, and the first one is the gate: the attestation must still be valid on 31 December 2026. The other two are that the material has undergone no change altering its composition or sanitary characteristics, and that the substances, formulations or components it contains are already on the national positive lists referred to in article R.1321-48 (Légifrance, Décret n° 2026-80).

That first condition is the one that gets dropped in retelling, and dropping it inverts the meaning. The transition is not a blanket extension of every ACS ever issued: an attestation that has already lapsed before the end of 2026 does not ride through to 2032. So a supplier telling you ACS is already dead is wrong; one telling you it is unchanged and permanent is also wrong; and one waving a long-expired ACS certificate at you and pointing to “2032” is wrong in the way that actually costs you a submittal. Check the expiry date on the certificate itself before you rely on the transitional period.

Germany: the distinction almost every buyer gets backwards

German law sets the substantive requirement in the Trinkwasserverordnung 2023. Section 14 applies to “Werkstoffe und Materialien, die für die Errichtung oder Instandhaltung von Wasserversorgungsanlagen verwendet werden und die Kontakt mit dem Rohwasser oder Trinkwasser haben” — materials used in constructing or maintaining water supply installations that contact raw or drinking water — with four core requirements: materials must not reduce health protection, impair sensory properties, promote microbial growth, or release substances beyond the unavoidable (TrinkwV 2023 §14, gesetze-im-internet.de). Section 15 then makes the Umweltbundesamt assessment bases legally binding: “Zwei Jahre nach ihrer Bekanntmachung im Bundesanzeiger wird die jeweilige Bewertungsgrundlage rechtsverbindlich” (TrinkwV 2023 §15). The KTW-BWGL is one of those bases.

Here is the distinction. German law makes compliance with the KTW-BWGL binding. It does not mandate DVGW certification. TrinkwV §15 contains no mention of DVGW or any mandatory certifying body, and it recognises testing conducted in EU member states, EEA countries or Turkey (TrinkwV 2023 §15). DVGW says so itself: its guidance states these assessment bases must be complied with two years after publication per the Trinkwasserverordnung, and separately that “Zurzeit gibt es keine Zertifizierungspflicht” — currently there is no certification obligation — with conformity demonstrable via test reports or a declaration of conformity (DVGW, UBA-Bewertungsgrundlagen Kontakt mit Trinkwasser).

A gap we will flag rather than paper over: we could not open the Umweltbundesamt listing page for the Bewertungsgrundlagen (HTTP 404), so we cannot enumerate every UBA guideline or state each one’s individual binding date. The binding mechanism is verified from TrinkwV §15. Do not accept a per-guideline effective date from anyone without re-verifying it at source.

The four schemes side by side

Every entry in that table is sourced to a government legislation portal or a standards-body record, not to a certification consultancy. That is deliberate: the mandatory-versus-voluntary question is exactly where consultancy marketing is least reliable, because the consultancy is selling the certificate.

Now the GCC question — and the honest answer

The practical question: does holding any of the above get my pipe into Saudi Arabia or the UAE as a potable water product?

Our finding, stated plainly: we searched the official sources and found no published mutual-recognition clause for foreign drinking-water-contact certifications in the GCC. No GSO, SASO or MOIAT document we could open states that NSF/ANSI 61, WRAS, ACS or KTW/DVGW is accepted as a compliance route. What we checked, so you can judge the search rather than take our word: the GSO GCC Conformity Assessment Scheme page, the GSO conformity procedures page and homepage, the SASO ACAB (Acceptance of Conformity Assessment Bodies) page, the MOIAT “Issue Conformity Certificates for Regulated Products” service page, and a full-text search of the official SASO technical regulation PDF for pipes. Every one of them returned zero hits on the specific question of mutual recognition of foreign drinking-water-contact certificates. Several of those documents are substantial and we quote them below on other points — the null result is about the recognition clause, not about the pages being empty.

Be careful what a null result means: not finding a clause is not proof none exists — a document could sit behind a portal we could not reach, or in Arabic-language material we did not retrieve. What we can say is narrower: two independent search paths — the Saudi technical regulation on one side, the GSO conformity assessment scheme on the other — produce the same absence, and neither contains a clause that would let a foreign certificate stand in for the local route. That is a consistent absence across sources, not a positive statement by any regulator that foreign approvals are refused. Plan against the absence; do not quote us as saying the regulators have ruled on it.

A full-text grep of the official SASO Technical Regulation for Building Materials Part 5 (Pipes used in Water, Electricity and Gas Networks) for NSF, WRAS, ACS, KTW, DVGW, “mutual” and “recogni” returned zero substantive hits. The regulation instead cites SASO-adopted EN standards — for example SASO EN 1213 for potable water supply valves in buildings — and requires conformity assessment Type 3 per ISO/IEC 17067 via a SASO-notified body. Its definitions reinforce the point: a Certificate of Conformity is “a certificate issued by SASO or a notified body,” and a Notified (Approved) Body is one “approved by SASO in accordance with the Regulation of Conformity Assessment Bodies” — though conformity assessment must not discriminate between products on the basis of origin (SASO, TR Building Materials Part 5).

The Gulf-wide picture matches: GSO states that “only bodies which have been approved by the GCC Standardization Organization as competent and impartial and which are publically listed in its register may be called ‘Notified Bodies'” (GSO, Conformity Tracking System). And the technical regulations approved under the GCC Conformity Assessment Scheme cover general product safety, G-marking, toys, low voltage electrical equipment, and water consumption conservation products — the last being efficiency-focused, not drinking-water contact safety. No potable-water-contact materials regulation appears among them (GSO, GCC Conformity Assessment Scheme).

Three things we could not determine, stated as gaps

The defensible framing — what these certificates are actually worth to you

None of this makes a WRAS or DVGW certificate worthless in the Gulf. It changes what the certificate is for. The defensible position, and the one we will put in writing, is: NSF/ANSI 61, WRAS, ACS and KTW/DVGW are commercially persuasive evidence of material safety to consultants and EPC buyers, but they carry no automatic legal standing in GCC conformity assessment.

That produces two workstreams buyers keep collapsing into one:

• The regulatory route. Getting the goods legally onto the market, through SASO-notified or GSO-approved bodies and the conformity assessment procedure in the applicable technical regulation. A foreign potable-water certificate is not a substitute for it on any evidence we could find.
• The specification route. Getting the product accepted into the project consultant’s submittal. Here a recognised European or American drinking-water-contact certificate is genuinely useful, because the consultant is making a technical judgement about material safety and wants third-party evidence. This is where these schemes earn their keep in the Gulf.

Different gatekeepers, different documents, different failure modes. Clearing customs does not get you into the submittal; being in the submittal does not clear customs.

So strike this sentence from your own quotations: “WRAS approved, therefore accepted for potable water in Saudi Arabia.” If a supplier writes it to you, ask for the clause — regulation number, article, mutual-recognition provision. If they cannot produce it, they are repeating a competitor’s website, and you are about to build a submittal strategy on it.

What IFANNova actually holds, and what we will not claim

IFANNova is a French brand; our pipes and fittings are manufactured at our own plant, Zhuji Fengfan Piping Co., Ltd, in Zhuji, Zhejiang, China (per our catalogue). We do not claim Made in France — stating that plainly is a compliance position, not a marketing one.

Our plant’s certifications include SKZ, CE, WRAS, DVGW, SGS, TSE, GOST-R, ISO 9001 and ISO 14001 among others (per our catalogue). Certificate numbers, validity dates and exact scope coverage: Coming soon. That scope caveat matters most here: a potable-water approval attaches to a defined material, formulation and product family — not to a company. Until we publish the exact scope wording of each certificate, do not assume any of them covers the specific item in your BOQ. Ask which product families are in scope and we will tell you what we can and cannot evidence.

Our PPR PN20 material is described in our catalogue as non-toxic and suitable for drinking water, with recycled content capped at ≤10% (per our catalogue) — a material description from our own documentation, not a regulatory clearance, and we will not present it as one. Our HDPE PN16 pipe is marked “GERMANY STANDARD DIN8077/8078” (per our catalogue); we report the print legend and do not claim conformity to it, and for anyone reading the marking closely, DIN 8077/8078 is a polypropylene standard series whereas the series associated with PE is 8074/8075.

One hard limit before you plan around us: our pressure pipe production tops out at Φ110 mm (HDPE PN16 and UPVC 806 PN16 both Φ20–110; PPR PN20 only 20, 25 and 32 mm in 4 m lengths), and our PVC 902 range — pipe Φ32–110, 1902 fittings Φ32–160 — is non-pressure drainage, not a potable pressure line (per our catalogue). We cannot supply DN150–DN400 pressure mains. If your potable scope includes trunk or transmission mains, that portion is outside our production and no certificate discussion changes it. Full range detail is on the Middle East page.

What to do instead of assuming

Since we cannot give you a recognition clause that does not appear to be published, here is the sequence that protects a project. Confirm with SASO, MOIAT or your notified body whether your product is a regulated product in the destination market, in writing and against your exact HS code — we could not retrieve MOIAT’s regulated-products list, so do not budget on assumption. Confirm which conformity assessment route and which bodies are accepted, remembering certificates must come from bodies approved or notified by SASO or GSO. Ask the client’s engineer, in writing and before the order, which potable-water evidence they will accept in the submittal — that is where WRAS, NSF, ACS or KTW evidence genuinely helps. Ask your supplier for certificate scope rather than existence: number, validity, covered product family. And verify anything time-sensitive at source, since the French regime is mid-transition and German binding dates run per guideline.

If any of that comes back differently from what a supplier told you, believe the regulator and the consultant. That includes when the supplier is us.

Frequently asked, answered without hedging

Will WRAS or DVGW get my pipe approved for potable water in Saudi Arabia or the UAE? We searched the official sources and found no published basis for saying so, and the SASO and GSO texts we could open point the other way — both require bodies approved or notified by themselves. Confirm with your customs broker and a SASO-notified or GSO-approved certification body. We will not tell you it is sufficient when no regulator has said so.

Does IFANNova hold WRAS and DVGW? Both are listed among our plant’s certifications (per our catalogue). Certificate numbers, validity dates and scope coverage: Coming soon. Ask for the scope against your product list at enquiry.

What does a potable water approval cost in the GCC? We could not verify any GCC, Saudi or UAE registration fee, tax rate or certification cost for potable water products from an official source, so we publish none. Ask your certification body for a quotation.

Can you supply DN200 potable mains with a potable certificate? No — not because of the certificate, but because our pressure pipe range ends at Φ110 (per our catalogue).

Send the Enquiry

If your specification names a potable-water approval, send us the clause. We will tell you which of our product families we can evidence against it, which we cannot, and where the honest answer is that no published recognition route exists and you need your certification body’s confirmation instead. That is a slower answer than “yes, we are approved.” It is the one that survives a submittal review.
