We know which water treatment technologies and manufacturers best fit your site. Then we run a competitive tender and calculate each offer’s payback from all its savings and costs, not just the price.

What our clients say
“External wastewater handling was costing us a lot. Caskade gave us a comparison with clear figures, and we chose the solution that fits us best.”
Owner, resort & campsite, South of Spain

From our manufacturer panel
Have you considered the technical options? International manufacturers? Three examples:
Showers that filter and recirculate their own water, and basins that send handwash water to the toilet cistern. Fitted room by room, no central plant.
A compact unit treats water from showers and basins and feeds it back to the toilets.
A containerised plant outdoors treats mixed wastewater for gardens, pitches and green areas.
Caskade gets you real vendor proposals tailored to your needs and compares them on what matters: payback, net returns and technological fit.

Supplier C · Option C
Supplier D · Option D.1Based on a real Caskade Eval, with figures adjusted. Supplier names hidden. Payback excludes running costs; 5-year net gains include them.
A commercial laundry in Oslo wanted lower water use. An inline process-water filter that recycles laundry water cut use per kg of textile by 37%, saved about 4 million litres in one year, and brought payback to 0.8 years as local water prices rose.
A 4-star beachfront resort and campsite at the Costa Dorada is spending significant amounts on water yearly. A Caskade Eval is currently comparing options for on-site reuse. A modular and containerised solution from a German manufacturer promises to amortise in 3.5 years.
A resort & campsite in the South of Spain lacked access to a sewer and paid for wastewater disposal via tanker trucks. A Caskade Eval showed that more than 70% of the wastewater can be recovered with a centralised wastewater treatment unit from a German manufacturer supported by circular showers.
A galvanic parts manufacturer faced rising hazardous waste disposal costs from heavy-metal plating effluent (Cu, Cr, Ni). A vacuum distillation unit now recovers 97% of the water as clean distillate and cuts hazardous waste volumes by 97% (zero liquid discharge).
Free first assessment
Free. We show you which solutions could work on your site, whether they pay off, and say so plainly if the answer is not yet.
Free first assessmentFree
You get: the solutions that could fit your site, how much of your water you could reuse, and what that could save as a share of your water bill, where your data allows. If nothing pays off yet, we say so.
Caskade EvalFixed fee
Priced, comparable proposals ranked by payback, and a decision you can defend. We only go ahead if the free first assessment shows it makes sense.
Offers from 3–5 manufacturers
Real offers with prices you can use as you see fit: choose with figures in hand, take them to your board or finance team, negotiate, or go straight to the manufacturer you pick.
You spend months comparing documents from the first three manufacturers you found.
You get: one quote for their system.
Quotes are free because they’re designed to sell one solution. Running costs (operation & maintenance, consumables, energy) rest on different assumptions and leave out different items, so quotes can’t be compared line by line. A pilot goes further: it’s smaller than the full plant, but it needs the same connections to your site. You integrate one system before you’ve seen the alternatives, and it tests only one technology from one manufacturer.
You get: a choice among the few brands they represent.
Distributors typically hold exclusive contracts with a handful of manufacturers and earn a margin on what they sell. Anything outside their catalogue, including most newer technologies, never makes the list.
You get: an engineering report, rarely with real prices.
Consultancies are built for complex engineering and priced accordingly. Their reports seldom include vendor proposals, and their supplier networks are small.
You get: 3 to 5 priced proposals on one baseline, ranked by payback, in weeks, not months.
Ever heard of recirculating showers? Or electrocoagulation? From a database of 500+ specialised manufacturers across countries, we preselect the best-fitting solutions and run a structured tender between the top candidates.
We fill the data gaps and handle questions and follow-ups with manufacturers. Our Evaluation Engine runs a total cost of ownership analysis for each proposal, including running costs and delivery. You get a clear comparison, with proposals and prices attached, that will be useful in future conversations.
Our manufacturers know they’re competing against different technologies, not just similar products, so they price accordingly. Pick the shortest payback, the highest net return or the lowest investment, with financing options included where available, then continue with your chosen manufacturer, figures in hand.
Start saving without paying the full investment upfront: financing, subsidies and deductions can spread or reduce the cost of your solution.
Some manufacturers already include leasing or deferred payment in their offer. Where they do, we include it in your Caskade Eval.
Caskade helps you identify and apply for the subsidies and tax deductions that may apply to your project.
Get your solution through leasing or a rental with a purchase option, via specialised banks and lessors. Caskade arranges it with them for you; we are not the lender.
These are just some of the industries that pay the most for water or are most exposed to supply risk.
