In the community of Piaseczno, residents were offered subsidies from the commune's budget for the purchase, assembly and construction of elements forming rainwater systems to retain rainwater and meltwater, e.g. absorbent wells, moguls, rain gardens, and retention reservoirs. It is a continuation of the financial support program for residents from the previous year.

Housing communities and natural persons can apply for financial assistance.

The subsidy regulations provide for the financing of 80% of the documented costs of the investment, but not more than PLN 5 000 for natural persons and not more than PLN 10 000 for other legal entities.

Subsidiaries are obliged to maintain the financed investment for at least 3 years. If this condition is not met, it will be necessary to return the subsidy in full with interest.

Applications could be submitted from February 1 to September 1, 2021 or until funds were exhausted. On September 17, due to the use of the provided budget, the call for applications for financing investments for collecting rainwater was suspended. Any information about re-launching the program will be posted here.
