Cogem acquires TD eau: its point-of-use water treatment network reaches Provence

How COGEM, the point-of-use water treatment specialist based in the Lyon metropolitan area, acquired the business assets of TD eau's site in Gémenos (Bouches-du-Rhône) in spring 2024 — the need, the approach, the stakes and the macroeconomic reading of a local acquisition in which the real assets are the customer base, the installed equipment and the maintenance contracts.

The acquirer

COGEM, the consolidator of point-of-use water treatment

Founded in 1996 and based in Vaulx-en-Velin, in the Lyon metropolitan area, COGEM is a French company specialising in the sale, installation and maintenance of point-of-use water treatment solutions — water purified where it is actually used, in homes as well as in businesses and public buildings. A private company, it builds its model on long-term service: sale, installation and then maintenance, with control over every stage of the equipment life cycle and lasting customer relationships. Its published strategy is to build a territorial network by integrating specialist regional players — a series of acquisitions carried out in 2024 across several French regions, from Gradignan to Reims and Arles, in which the Gémenos deal is the Provence milestone.

TD eau, water treatment expertise — the Gémenos business

TD eau has been a water treatment specialist for more than twenty years, focused on point of use — the same trade as the acquirer — serving homes, multi-occupancy buildings, commercial premises and industry, with a range covering filtration, water softening, drinking water treatment, reverse osmosis, iron removal, nitrate removal and Legionella control. Its model combines design and engineering, installation and maintenance, built on the two economic pillars of the trade: maintenance contracts, which protect customers' investment and generate recurring revenue, and equipment rental, which covers equipment, servicing and warranty in a single monthly fee. The deal concerns specifically the business assets (fonds de commerce) of its Gémenos site in the Bouches-du-Rhône — the deed, registered in spring 2024, transfers the business, its customer base and its local footprint to an acquirer in the same trade, with continuity of service to customers as the very logic of the structure.

The rationale for the deal

Why this acquisition, and why this target

For COGEM, the challenge is that of any local service business: you cannot serve a territory without being there. Point-of-use water treatment lives on maintenance rounds, fast call-outs and local recommendations — so a catchment area is better bought than built, and it is bought in its purest form: the business assets, meaning the customer base, the maintenance contracts and the goodwill, without the liabilities of a company. "To progressively strengthen its territorial network and its service offering", says the group's communication: after Gradignan in the south-west, Reims and Arles, the acquisition of the Gémenos business sets the Bouches-du-Rhône milestone — the Aubagne–Aix–Marseille arc — in a 2024 series that, business by business, is building national coverage of the same trade.

The strategic rationale: acquiring the catchment area in its purest form — the customer base, the contracts, the local footprint

On the target side, TD eau's Gémenos business offered exactly what the investment thesis was looking for: the same trade — point of use, down to the vocabulary; more than twenty years of expertise covering the seven families of treatment solutions, from water softening to Legionella control; a twofold economic base of recurring maintenance contracts and equipment rental — revenues that transfer with the business and can be measured before they are bought; and a prime location: Gémenos, at the junction of Aubagne, Aix-en-Provence and Marseille, in a region where hard water makes treatment a long-term equipment need. The fact that acquirer and target share the same trade did the rest: for the business's customers, the new owner speaks the same technical language — continuity of service as a given.

The macroeconomic reading

Local point-of-use water treatment is consolidating, one business at a time

This deal illustrates a discreet but methodical consolidation: point-of-use water treatment — softeners, filtration, reverse osmosis — is driven by structural trends, from growing awareness of water quality and hard mains water in many regions to the health requirements of commercial and multi-occupancy buildings, including Legionella prevention; yet it is still served by a fragmented base of regional installers, where value lies in portfolios of maintenance contracts and installed customer bases. Consolidation advances one unit at a time: through purchases of business assets, the instrument that transfers the customer base, the contracts and the goodwill without taking over the company — the acquisition closest to the ground that business law offers.

The deal's reach is domestic and modest in size, but structuring in its method: from the Lyon metropolitan area to the Bouches-du-Rhône, a specialist founded in 1996 adds the Provence milestone to a published 2024 series — Gradignan, Reims, Arles — that is gradually building a national network in the same trade. For the customers of the Gémenos business, private households and professionals alike across the Aubagne–Aix–Marseille arc, the deal is first and foremost a promise of continuity: the same service, the same equipment maintained, a new owner from the same trade — and for the market, proof that national consolidation of point-of-use water treatment can be built quietly, one maintenance contract at a time.

The adviser's role

Collaboration Capital's added value on this buy-side mandate

On this deal, Collaboration Capital acted as buy-side adviser. Acquiring the business assets of a local service company plays out in four stages — and in point-of-use water treatment, where the assets are customers and contracts, each stage has its own yardstick.

I

Understanding the mandate

The scoping starts from the trade's sales channel: at point of use, customers come from local recommendations, the installed equipment base and the maintenance contracts that bring the technician back year after year — value is territorial by nature. For a serial consolidator, the relevant acquisition unit is therefore not always the company: it is often the business assets — customers, contracts, goodwill — bought area by area, against a simple but demanding brief: exactly the same trade, a catchment area that complements the existing network, and recurring revenues that can be measured before the acquisition.

II

Target sourcing and assessment

Local water treatment is an archipelago of regional installers that industry classification codes lump together with plumbing and HVAC. The real filters are those of recurrence: the share of maintenance contracts in the business — the revenues that transfer with the business assets; the density and age of the installed base; the customer mix between homes, commercial premises and multi-occupancy buildings; technical coverage — from softeners to reverse osmosis and Legionella prevention; and the fine-grained geography of the catchment area: in Gémenos, the junction of Aubagne, Aix and Marseille, in a region where hard water structurally sustains demand.

Off-market channel

Off-market sourcing

Collaboration Capital's technological edge lies in its method for identifying targets: semantic clustering and machine learning algorithms, rather than industry and administrative classification codes. Official activity codes put companies into boxes that cannot answer an acquirer's overall objective — they ignore the real activity, the distribution model, the customer profile and the business model. Semantic analysis, by contrast, reads what companies actually do and maps those that match the acquisition thesis in all its dimensions, including — above all — those that are not for sale. In the market for this deal, that is what singles out, among installers that classification codes merge with plumbing, the point-of-use specialist with recurring maintenance contracts — the business worth acquiring.

On-market channel

On-market sourcing

The same infrastructure applies to the visible market: the technology extracts the acquisitions and disposals completed in the client's target sector — and, above all, it identifies the dealmakers who led them: lawyers, auditors, financing banks and investment funds, assessing how specialised each one is in the sector concerned.

Collaboration Capital thus identifies the dealmakers who are genuinely active in the target sector, finds their professional contact details — emails and phone numbers — and reaches out to present the client's acquisition project. This is how the on-market channel is fed: it gives the client access to the disposals circulating in the market, when they circulate, through the people who circulate them — an active channel for local service businesses, whose sales go through local networks and specialist listings as much as through intermediaries.

Combined, these two channels raise the level of the sourcing game: Collaboration Capital's technology infrastructure becomes a genuine game changer for acquisition projects. It is designed for ambitious companies that want to base their external growth on this high-end infrastructure.

III

Direct approach and introductions

Approaching the owner of a local service business means dealing with a simple reality: the customer base is a personal relationship, built job after job, and selling it commits the owner's word as much as their assets. A sale of business assets offers flexibility here — selling the business without necessarily selling the company — and the pitch rested on a shared trade: a buyer who speaks the same technical language, from sizing a softener to maintaining a reverse osmosis unit, who takes over the maintenance contracts in order to honour them, and whose series of acquisitions, published region after region, shows that integrating local businesses is its core skill.

IV

Negotiation through to closing

Structuring an acquisition of business assets has its own grammar: a precise definition of the scope transferred — the customer base, the maintenance contracts and their transferability, the goodwill, stock and service equipment; an audit of recurrence — the age of the contracts, their renewal rate, dependence on key customers; then the protective formalities of a French sale of business assets, from prior notice to statutory publication — the Gémenos deed followed that path in spring 2024. Continuity of service to customers was treated as the substantive clause of the deal: the same trade on both sides, equipment maintained without interruption — the condition for the customer base, the asset actually bought, to stay.
