Incomparable offers
Each vendor starts from different assumptions: COD, guarantees, cost structure. The result isn’t a real comparison — it’s a set of proposals that are hard to cross-check. The decision ends up depending on who presents best.
Every water treatment vendor has a favourite technology. We don't.
Every site and effluent is different. And yet, manufacturer proposals are built to sell a standard solution, not to compare the options.
EvalAgua finds the optimal solution for each site and effluent, evaluating 5+ technology routes and 30+ manufacturers on one baseline.
What’s at stake
A 15-year decision should be based on differentiated data — not the first offer that arrived.
⏱
The pilot trap
Some subsidised pilot projects close the evaluation too early. After months of testing a solution, switching stops being a real option — even if it isn’t the best one.
👤
If the installation underperforms, the OEM isn't in the room — you are.
If the installation underperforms on output, reliability or O&M cost, the approval chain wants to know why you chose this vendor, at this price, over the alternatives. Without a documented comparison, the exposure is yours.
Why EvalAgua
The only part of the chain built to compare solutions, not to sell one.
250+ vendors in Europe 1k+ treatment products 5+ reuse applications 5+ technology routes
A justified recommendation
Deliverable: 2–5 manufacturer offers compared, with one or more recommended solutions.
Find the optimal solution for your site and effluent.
We evaluate each option using the same starting data — not a proposal built around a solution you already decided on. The result is a document you can verify and take to any manufacturer.
We maximise value, not just reuse.
We identify where reuse really pays off — before comparing technologies and vendors. More reuse doesn’t always mean more value.
We use the best available data.
If your plant has an active WWTP, we use your lab data from 3 to 18 months to capture variability and load peaks. If not, we coordinate sampling and lab analysis.

Why choose EvalAgua Evaluation
Compare first. Decide with confidence.
Defensibility
A comparison across all relevant technologies and OEMs on one shared baseline
Choose with better information and defend your choice.
Clarity
Start the OEM conversation informed
A documented comparison means you arrive at the selected OEM with a clear rationale — and a spec that reflects what you actually need, not what was easiest to sell.
Speed
All routes compared in parallel — not one vendor at a time
No need to brief five vendors, nor wait for proposals. You arrive at the selected OEM with the work already done.
With EvalAgua
What you don't have to do
Translate between incomparable proposals from different OEMs
Explain your plant from scratch to five different vendors
Build the internal case for your finance direction
Sectors
Who benefits most from on-site water treatment:
WWTP retrofit possible
You already treat your wastewater? Don't let that value go down the drain!
Make use of your existing treatment plant and append a purification device to reuse the effluent.
Industrial Laundries
Especially retrofit of mixed-brand washing machine fleets
Resorts & Golf Courses
Cut costs and keep your grounds operational during drought restrictions
Other
E.g. residential: water reuse solutions per building, per riser, or even per shower.
