The ladder you replace this year is the one someone will climb down for 20 years.

A reservoir ladder at the end of its life, a broken cast-iron hatch, rusting fall protection bars: we make what replaces them, in composite, which doesn’t rust. You price each structure in workwith., our pro portal, and we submit our invoices via Chorus Pro, the French public-sector invoicing platform.

01 — Your situation

Equipment at the end of its life, on this year’s programme.

You are responsible for your local authority’s reservoirs, treatment plants and pumping stations. You keep them when contracts change. You replace their equipment as your programme goes on: the reservoir ladders this year, the pumping station hatches next year.

You choose the equipment and you request the quote. Then your elected official signs, and your finance department or your stores department places the order. The quote goes round your departments.

On the ladder, nobody will read the quote.

A technician will lift the cover, raise the bars, then climb down. What they will have under their feet and under their hands is decided on your quote.

02 — Your structures

The structure stays damp, the equipment no longer rusts.

A reservoir or a pumping station never really dries out. On metal, corrosion always comes back in the end, and you have to replace it again. Composite doesn’t rust.

Reservoirs, tanks, treatment plants

What we see
The original ladder is reaching the end of its life, in a damp tank, in contact with water intended for consumption.
What composite changes
Our drinking water ladders don’t rust, and their material is ACS-certified: the certificate ships with every ladder. For hatches, we offer a double nested cover with 2-point locking.

Wastewater

Pumping stations, wastewater treatment plants, basins

What we see
The cast-iron hatch is heavy, or broken. The metal bars are eaten away, or there are none. And H₂S attacks metal.
What composite changes
The hatch opens with one hand, and the optional fall protection bars fit inside its frame. The ladder stays sound, with no repainting, and so does the guard-rail around the basins.

Fall protection bars

Under the hatch, the bars.

Replacing the hatch is the right time to add what’s missing underneath. The fall protection bars are optional: they are ordered with the hatch, in the same estimate, and fit inside its frame. For our T1-Std hatches, they come in four sizes, from 600 × 600 to 1,500 × 800 mm. For a chamber or shaft in civil works, we make a module that is cut to fit on site. And at 1,200 J, the bag does not pass through.

03 — Your project

A quote for every structure, an invoice via Chorus Pro.

In workwith., our pro portal, you price one structure, then the next. As the programme moves forward, the home screen shows where each project stands and what it needs from you. And each one has its own account manager.

    01

    Price at your rates

    You do the pricing yourself, at your rates. You configure your ladders to the height of the structure. For a hatch, you choose the size and, on the T1-Std 600, 800 and 1000, the position of the hold-open stay. Fall protection bars and guard-rails are added to the same estimate. Your account manager checks it, adapts it to the structure and sends you the quote. If you have a schedule of unit prices (BPU) with us, they use the prices and item numbers from your schedule on the quote.

    Approve

    Once the quote is signed on your side, you approve it in Messages or by email: we are the ones who turn it into an order. Standard or configured equipment goes into production with no drawings to approve. For a structure that needs a design study, our design office uploads the installation drawings to your portal, with their revision. You approve them, or you leave a comment: production waits for your go-ahead.

04 — Who we are

Before you sign, documented proof.

We are idréva, a Normandy-based manufacturer of composite access equipment since 2015. A team that has been working with composite for more than twenty years, in our own factory in Rives-en-Seine since January 2025. You are choosing for other people: for the person who signs, and for the person who will climb down.

50 kg× 32.40 mTHE BAG DOES NOT PASS THROUGH
Diagram of the test: a 50 kg bag, dropped three times from a height of 2.40 m onto a fall protection grid resting on its frame. The bag does not pass through.

This is the impact test from the INRS ED 6076 method, the INRS document on pumping stations. On our fall protection grids and bars, the bag does not pass through. A third-party inspection body has validated it.

The test report is in the Documents section of your portal.

Drinking waterACS

The material in contact with the water is certified.

On our drinking water ladders, the material has passed the ACS migration tests, in an approved independent laboratory. The certificate ships with every ladder, and you will find it in your Documents.

Workshop exitSignal™ “Approved” label, with the number, date and signature

Only green leaves the workshop.

Every piece of equipment is inspected in our Rives-en-Seine workshop. Equipment that ships carries the green “Approved” Signal™; on the label, its number, the inspection date and the inspector’s signature. The rest stays with us. This inspection is photographed: you can see it in “Track production”.

The Signal™ programme
Standards
  • Our ladders comply with EN ISO 14122-4 and NF E85-016
  • Our guard-rail is designed to NF E85-015 and EN ISO 14122
05 — Why we do all this

The person who will climb down that ladder may not be on your team yet.

We will probably never meet them. Yet it is for them that you are replacing it, and for them that we make it in composite.

07 — Common questions

Replacing your ladders and hatches, in six questions.

Six short answers. For anything else, your account manager replies in the pro portal.

You create one estimate per delivery site, and each one becomes a quote. Your local authority’s sites are listed in Account and company: you prepare an estimate for each one, at your rates, with its preferred date. Your account manager checks each estimate and sends you the quote within 48 working hours. And each person in your local authority can have their own access, approved by your account manager.
