Greenhouse Water Consumption Calculator.
Estimate annual m³ water demand, peak daily draw and storage sizing for a commercial greenhouse or hydroponic project. Supplier-neutral scoping tool for irrigation and pump-station RFQs.
How much water does a commercial greenhouse use?
Greenhouse water demand equals daily crop water use (L/m²/day) × area × production days, plus leaching fraction and system losses, giving annual m³ and the peak-day flow used to size storage and pumps.
- Typical protected tomato/pepper demand is 3–6 L/m²/day at peak.
- Add a 15–30% leaching fraction for drain-to-waste systems.
- Recirculation with disinfection cuts total water demand by 20–40%.
- Peak-day flow, not annual volume, determines pump and reservoir sizing.
Estimate only — not a quotation. Outputs are indicative planning ranges based on the values you enter and typical commercial benchmarks. Real pricing, specifications and lead times vary by country, site conditions and supplier, and are confirmed only in written offers collected through a private RFQ.
Project inputs
Closed hydroponic systems recover 30-60% of drain.
Values are indicative. Local climate, crop and irrigation regime shift results — always calibrate with agronomist and hydraulic-engineering input.

What can change the result?
This is a preliminary planning estimate based on the values you entered. The variables below usually move the outcome most, and should be confirmed with an agronomist, engineer and supplier offers before final design.
- Crop and cultivar — water, climate and support requirements differ per crop
- Local climate: temperature, humidity, radiation and wind exposure
- Greenhouse type and technology level (tunnel, naturally ventilated, high-tech)
- Irrigation design, emitter spacing and application efficiency
- Water source, allocation and seasonal availability

Procurement answers behind these numbers
A model output only holds if the scope, contract route and delivery terms match the assumptions. These reference answers cover the commercial decisions that move the figure.
- Turnkey EPC vs separate equipment packages
- What belongs in a greenhouse equipment specification
- Normal payment milestones in equipment contracts
- Which Incoterms to use for greenhouse and irrigation equipment
- How long a commercial greenhouse takes from order to handover
- What is normally the owner's scope on a greenhouse project

Running these numbers for a client project?
Agronomists, greenhouse and irrigation consultants use this calculator for feasibility, then hand the project to us for supplier shortlisting, RFQ preparation and quote comparison. You stay client-facing and we work through you.
Your client relationship stays with you — we work through you and never contact your client unless you ask.
