Water abstraction for irrigation in Germany: permits and records

Irrigation in Germany requires a water permit. How farms measure, record and document abstracted volumes for levies and inspections.

PhytAI editorial teamPublished 6 min read

Key points

  • Permit: every abstraction for irrigation from groundwater or surface water requires a water permit from the lower water authority.
  • Duration and volume: in Lower Saxony, according to the Chamber of Agriculture, permits are usually limited to 20 years; the annual volume is assessed over a rolling ten-year period.
  • Drought: general orders can restrict irrigation times; according to Land & Forst, breaches can be fined up to 50,000 euros.
  • Bavaria: since 2026 a water cent of 10 cents per cubic metre applies; farms with their own well should have documented their meter reading on 1 July 2026.
  • Schleswig-Holstein: abstracted volumes must be declared every year by 1 March for the water levy, supported for example by measurements and field records.

Dry summers have made irrigation routine in many regions of Germany, not only for potatoes and vegetables. As water demand grows, so do the obligations: anyone abstracting groundwater or surface water needs a permit, must stay within the permitted volume and, in several federal states, must declare or pay for it every year. This article explains what the permit covers, how farms can measure and record abstraction properly and which state rules are new in 2026.

The water permit

According to the Chamber of Agriculture of Lower Saxony, water is a common good, not private property. Every abstraction for irrigation therefore requires a water permit, whether the water comes from a well or from a river, ditch or lake. The lower water authority at the district or independent city is responsible.

For the application, the chamber typically lists:

  • a description of the project
  • a calculation of water demand, in Lower Saxony prepared by the chamber according to guideline DWA-M 590 with climate, soil and crops
  • maps and site plans of the irrigated areas and planned wells with sensitive landscape features and biotopes
  • usually a hydrogeological assessment or a drawdown calculation
  • after drilling, the well construction profile and the log of soil layers

The permit sets duration, abstraction volume, abstraction point and conditions. According to the chamber, permits in Lower Saxony are usually limited to 20 years. The annual volume is averaged over a rolling ten-year period: more may be abstracted in dry years and correspondingly less in wet years. Exceeding the ten-year average can have serious consequences.

Measuring and recording

Because the permit sets a volume, the farm must be able to show how much it actually abstracted. The details, such as whether a calibrated water meter is required and when volumes must be reported, are set out in the permit and in state water law. Read the permit carefully and keep its conditions where irrigation is planned.

The following records per abstraction point have proven useful:

  1. Master data: name, location, permit reference, permitted annual volume, expiry
  2. Meter readings: at the start and end of the season, on larger farms also monthly
  3. Meter replacement: final reading of the old meter, initial reading of the new one, date
  4. Irrigation runs: field, crop, date and estimated volume per run
  5. Annual overview: measured annual volume and utilisation of the permit

The sum of individual irrigation runs is a plausibility check but does not replace a meter reading. If the two differ significantly, this can point to a faulty meter, a leak or forgotten runs.

Restrictions during drought

During pronounced dry periods, districts can restrict water abstraction by general order. According to a Land & Forst report from May 2026, such orders affect stationary and mobile irrigation systems, for example through time windows or temperature limits. Climate-adapted methods such as drip irrigation and stored rainwater from cisterns were not restricted in the reported case. Breaches of a general order can be fined up to 50,000 euros. In summer, check your district's announcements regularly.

Bavaria: water cent since 2026

Bavaria has levied the water cent since 2026. According to the Bavarian Farmers' Association, it amounts to 10 cents per cubic metre of groundwater abstracted. Those affected include agricultural and forestry businesses with their own well. The free allowance is 2,500 cubic metres in the short year 2026 and 5,000 cubic metres per year from 2027. The association recommended documenting the meter reading on 1 July 2026, for example from water meters or pump data; the authorities' request was announced for autumn 2026. Anyone who did not record the reading on the reference date should clarify with the water authority how the volume can be evidenced.

Schleswig-Holstein: declaration by 1 March

In Schleswig-Holstein a levy on abstraction from groundwater and surface water is charged under the Water Levy Act. The district of Dithmarschen describes the procedure: anyone abstracting water declares every year by 1 March the volume abstracted, the purpose, such as field irrigation, and the abstraction point. Measurement results, operating logs and field records are named as evidence. A payment request is only issued if the calculated levy exceeds 200 euros in the calendar year.

Other federal states

Other states also charge abstraction fees or require volume reports, with different deadlines and free allowances. The relevant state water act and your permit are decisive. If in doubt, ask the lower water authority or your chamber of agriculture.

Water in quality schemes

Besides quantity, quality matters. QS-GAP and GLOBALG.A.P. require a risk assessment of irrigation water and water analyses for fruit and vegetables. This is independent of the water permit and mainly affects vegetable and fruit farms.

Common mistakes

  • irrigating from a new well before the permit is granted
  • meter reading at the start of the season forgotten, annual volume only estimated
  • meter replaced without noting the readings
  • permit conditions kept only in a folder, not used for planning
  • the district's general order overlooked in midsummer

Water abstraction in PhytAI

PhytAI keeps abstraction points with their permit: reference, permitted annual volume and expiry. Meter readings are recorded per point, which gives the measured annual volume and the utilisation of the permit. Irrigation runs are assigned to an abstraction point as a field operation, so field, crop and volume remain traceable. PhytAI does not yet offer a state format for reports or levy declarations; the figures can be exported. The sum of field operations does not replace a meter reading.

Frequently asked questions

Do I need a permit for drip irrigation? The permit requirement is tied to abstracting water, not to the technique. Anyone abstracting groundwater or surface water for drip irrigation generally needs a permit; exceptions are governed by state law.

How long do I have to keep meter readings? This depends on the permit and state law. With an assessment over ten years, it makes sense to keep annual volumes for at least that long.

What happens if I abstract more than permitted? This can have regulatory consequences and put the renewal of the permit at risk. Talk to the water authority early if a higher demand is emerging.
