A water-law permit and report - the basics

Knowledge base · August 3, 2026

Many forms of using water - abstraction, discharge, damming, certain works - require formal water-law consent. For those running an activity connected with water, this is an important context in which monitoring also often appears.

This is an informational article - in a specific case always consult the current regulations (the Water Law) and, if needed, the help of a specialist.

What a water-law permit is

It is a kind of water-law consent required, among others, for:

• water abstraction (surface or groundwater),
• discharging sewage into water or into the ground,
• damming and retention, certain works and water structures.

Water-law consents are issued by Wody Polskie.

How long a permit lasts - a worked example

Validity periods are not discretionary: they are set by statute. In Polish water law (the Water Law Act of 20 July 2017, Journal of Laws 2017 item 1566) they run as follows:

The period runs from the day the decision becomes final. The practical consequence for monitoring is the same in every jurisdiction that works this way: with a discharge permit the renewal cycle is a handful of years, and the application for the next period rests on the supporting report - so the measurement series from the whole period is evidence, not an archive.

Check the equivalent provision in your own country - the structure (a permit for a fixed period, a supporting report, renewal on the basis of that report) is common; the numbers are not.

What the water-law report is for

The water-law report is a document (a descriptive and a graphic part) that forms the basis for issuing the permit. It describes, among others, the scope and manner of using the water, the structures and the impact on the aquatic environment - that is, it provides the authority with data for its decision.

The contents of the report are also defined by statute. In the Polish example it consists of a descriptive and a graphic part, and the descriptive part contains, among others, the identification of the installation, the purpose and scope of the intended use of water, a description of the water structures, the type of measuring equipment, the characteristics of the impact on waters and the legal status of the properties.

Note the item “measuring equipment”: the way of measuring is declared in the report itself, so the later monitoring is not free-form - it has to match what was declared.

Extending the permit

Only some permits can be extended, and the deadline is rigid. In the Polish example, Art. 414 of the Water Law allows a further period of validity to be set for permits for water services (among others water abstraction and sewage discharge), special use of water and long-term lowering of the groundwater table (Art. 389 points 1-3). This does not apply to permits issued without a period (the last row of the table above).

The Act describes the deadline like this: the permit does not lapse if the operator files an application for a further period “within 90 days before the expiry of the period” for which it was issued (Art. 414 para. 2). How to count that deadline in your case, confirm with the Wody Polskie unit that issued the permit. ⚠️ Whoever misses the deadline cannot extend the permit - they must apply for a new one, in the ordinary procedure.

You attach the report on the basis of which the current permit was issued, and a statement that the information in it remains current (Art. 414 para. 3). This is not a formality:

• if the authority finds that the data in the report are out of date, or one of the grounds for refusal in Art. 399 para. 1 applies, it refuses the extension (para. 6);
• an incomplete application has to be completed within 14 days, otherwise it is left unexamined (paras. 4-5).

The further period has its own maxima (para. 7) - under the general rule shorter than for the first permit:

• general rule: at most 20 years;
• discharge of sewage into waters or into the ground: 10 years;
• industrial sewage with particularly harmful substances into someone else’s sewerage: 4 years;
• extraction of stone, gravel, sand and cutting of plants: 5 years.

An application filed in time keeps the existing permit in force until the final decision, including a refusal (explanation on gov.pl, “Zgoda wodnoprawna krok po kroku”, 2024).

For monitoring, the conclusion is simple. A statement that the report is current is worth only as much as the data that back it. Collect them throughout the validity of the permit: when you apply for a further period, you will use them to show that nothing has changed, or to document what has. Better to know this before the deadline than from the authority.

Where monitoring comes in

Permits often impose control obligations - e.g. monitoring the quality and quantity of discharged sewage or of water in the area of impact. Then systematic, reliable data and its reporting become part of the obligations, and its credibility (see QA/QC) - crucial.

In practice

When monitoring is an obligation, what helps most is order in the data: fixed points, units, guidelines and readiness to export for reports. LimnoLog keeps measurements in this structure, lets you mark guidelines (e.g. the permissible values from the permit) and export the data to Excel for the report.
