Water treatment systems in Spain
Water treatment is the first engineering decision on most Spain projects. Aquifer over-abstraction in Almería and Murcia, plus desalinated supply on the coast, makes recirculation, drain recovery and nitrate compliance the deciding factors in permitting and retail audits.
Capacity is sized on peak demand — about 65 m³/day per hectare — plus buffer storage for treatment downtime and back-flush losses. At $0.60 /m³, recovery and reuse of drain water usually carry a shorter payback than any other water investment.
Where reverse osmosis is required, factor the energy cost at $0.160 /kWh and design concentrate handling and discharge compliance into the layout from the start rather than after commissioning.
Do I need reverse osmosis in Spain?
Only when sodium, chloride or total salinity exceed what the crop and substrate tolerate. Aquifer over-abstraction in Almería and Murcia, plus desalinated supply on the coast, makes recirculation, drain recovery and nitrate compliance the deciding factors in permitting and retail audits. Blending treated and raw water is often cheaper than treating the full flow.
All figures are indicative planning ranges for feasibility work — not quotations. Final specification and pricing come from qualified suppliers and engineers.

Specifying water treatment for a client in Spain?
Consultants and agriculture EPC advisors working on Spain projects use us to shortlist water treatment suppliers, prepare the RFQ pack and compare the quotes on a like-for-like basis. You decide how involved we are.
Your client relationship stays with you — we work through you and never contact your client unless you ask.
What to confirm before you contact greenhouse suppliers
Suppliers can only quote comparably when the same facts are on the table. This is the information a serious water treatment systems projects in spain request needs — bring what you have, and we will mark the rest as assumptions or open questions before anything goes out.
- Crop, variety and target market (local retail, wholesale or export)
- Production target per year and planned expansion phases
- Growing method: soil, substrate, hydroponic or vertical
- Country, site location, altitude and land status
- Temperature, humidity, wind and solar radiation profile
- Covered area now, and the area you intend to reach
- Water source, availability, storage and water analysis
- Irrigation, fertigation and filtration/treatment requirement
- Cooling, heating, ventilation and shading requirement
- Grid supply, solar, backup power and energy cost
- Automation, sensors, monitoring and labour model
- Packing, pre-cooling, cold storage and export requirements
- Budget range, buyer contribution, financing need and timeline
- Permits, environmental requirements and internal approvals
How the process actually works
- 1Initial conversation — you describe the project in your own words, 24/7.
- 2Structured requirements — we organise what is confirmed, assumed and still missing.
- 3Project or RFQ brief — one comparable document instead of scattered emails.
- 4Human review — David and the team review qualifying projects.
- 5Appropriate routing — supplier discovery or financing-pathway context, where justified.
Next step
Human-reviewed project routing and financing-pathway discussion generally start from an expected total project value of about USD 250,000. Below that, use the planning guides and calculators — they are free and no request is required.
SeedMatch structures requirements, prepares RFQs and provides supplier-discovery and financing-pathway context. We are not a manufacturer, farm operator, EPC or engineering contractor, lender or pricing authority, and buyers are never connected to suppliers automatically. Sending a request does not guarantee a supplier, price, financing, yield, permits or delivery.
