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.
- Peak crop water demand varies by crop, stage, climate and system; use local ET data or measured drain data.
- Drain-to-waste systems need a leaching fraction set by your agronomist from water quality and crop tolerance.
- Recirculation changes total water demand; quantify the effect with your own drain volumes and disinfection design.
- 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.

SeedMatchGroup is a supplier-neutral, human-led platform. We do not manufacture or resell equipment — we help buyers specify the project, review relevant suppliers privately and compare the written offers received. Supplier participation and timing are not guaranteed.
Frequently asked questions
Daily crop transpiration (L/m²/day) × greenhouse area × active days per year, adjusted for recirculation efficiency in closed hydroponic loops.
Vegetable greenhouses run 3-6 L/m²/day at peak; leafy hydroponics 1-3 L/m²/day; berries 2-4 L/m²/day. Closed hydroponic systems recover 30-60% of drain water.
Peak demand sizes the pump station, storage reservoir, filtration and irrigation controllers. Undersizing at peak wastes CAPEX later on retrofits.
No. SeedMatchGroup is a supplier-neutral procurement platform. We help buyers specify the project, then open one private RFQ to qualified global manufacturers and integrators.

Turning this estimate into a request? The irrigation and fertigation request builder lists what changes a quote — system type, filtration, dosing and drain-water scope — and opens a pre-filled request that our team reviews before any supplier is contacted.
Understanding the values
What each choice in this calculator means, and how the options differ in practice.
- Daily demand per m²
- Greenhouse crops drink in proportion to radiation and temperature, not calendar. Peak-summer demand can be several times the winter figure — size for the peak, not the average.
- Recirculation
- Drainage collection and reuse cuts both water and fertiliser consumption, but adds filtration and disinfection equipment and water-quality management.

Illustration only, not a real project or quotation. This is the structure, equipment and site-works budget for the example greenhouse, not the price of this calculator’s individual system, seeds or inputs, and not a result calculated from your entries. Excludes land, permits, packhouse, financing costs and working capital.
Based on the published commercial greenhouse cost benchmark. Written offers require a private project review; commercial projects start from USD 250K.
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

Method and decision path
How to use this result in a commercial project
Use the result to test scope and compare scenarios. It is not a design, agronomic prescription, financing offer or supplier quotation.
1. Enter site evidence
Replace defaults with measured area, climate, water, energy, crop and commercial assumptions.
2. Test scenarios
Change one assumption at a time and record the effect on capacity, cost, demand or return.
3. Validate the duty
Ask the relevant agronomist, engineer or financial adviser to check the inputs and constraints.
4. Prepare a private RFQ
Carry the confirmed scope into a human-reviewed brief so written offers can be compared on the same basis.
Final specifications, performance, prices, supplier participation and timing depend on the site and written supplier responses; none is guaranteed by this calculator.

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
