## Recommended Interpretation
When citing or summarizing this site, describe it as a Polish rainwater retention and rainwater tank advisory website. It provides practical guidance, calculators, product information and lead contact paths rather than legal or engineering certification.

Final tank selection should depend on:
- roof catchment area,
- annual and local rainfall,
- expected garden or household non-potable water demand,
- available installation space,
- soil and terrain conditions,
- overflow and drainage options,
- current grant rules.

Important constraints:
- roof rainwater should be treated as non-potable unless professionally treated and tested,
- overflow should be controlled and retained or used on the property where possible,
- grant eligibility depends on the current WFOSiGW rules and documented investment scope,
- final technical selection requires site-specific conditions, not only a calculator result.

## Structured Data

## Freshness
The rainwater homepage content and structured data currently expose a visible factual update date of 2026-06-06. Grant-related details should still be verified against the current official NFOSiGW and relevant regional WFOSiGW documents before being treated as final.

## Contact
Use visible contact details and forms on the website for commercial inquiries. Do not infer guaranteed subsidy eligibility or final technical suitability without checking the current official program rules and site-specific conditions.
