# Poland expands flood management, adds river renaturation > Live situation record from CLSTR: https://clstr.news/situations/poland-expands-flood-mitigation-infrastructure > Updated: 2026-07-31T08:39:46.000Z. Sources: 39. Developments: 10. Poland’s climate‑adaptation programme is expanding flood management and river renaturation nationwide. New basins are being built in Kocmyrzów‑Luborzyca (≈1,900 m³, 85 % EU‑funded) with a 430‑day target, while tests at Racibórz’s retention‑tank led to plans for an extra basin to protect streets and a national road. Toruń is deepening the Kaszownik reservoir with a near‑10 million‑zł investment (over 6 million zł from EU funds) to increase flood‑mitigation capacity and public access. Projects also include rebuilding the Sieczka reservoir in Aleksandrów, modernising Starachowice’s Piachy Reservoir into a year‑round recreation centre, and installing piezometers around Lake Płotki to monitor its decline. Gmina Poniec is converting a dredged pond into a retention reservoir for the new Berlinek estate, and a 200 mm sanitary sewage network was approved in Gmina Szemud. The European Regional Centre for Eco‑hydrology highlights that river regulation peaked in 2003 (858.5 km) and fell to 47.4 km by 2023, prompting the State Water Management authority to promote blue‑green infrastructure and river renaturation to improve groundwater recharge and buffer flood and drought extremes. Recent contracts will modernise Pułtusk Pump Station No. 1, expanding its inlet and installing new pumps, and upgrade Jaworzno’s Bory estate water‑supply network by replacing 1,000 m of pipelines. ## Timeline ### 2026-07-31: Poland approves upgrades to Pułtusk flood pump station and Jaworzno water network Poland signed contracts to modernize Pułtusk’s flood pump station and upgrade Jaworzno’s Bory district water network, improving flood protection and water supply reliability for thousands of residents. 3 sources. https://clstr.news/cluster/poland-approves-upgrades-to-putusk-flood-pump-station-and-jaworzno-water-network ### 2026-07-26: Poland moves to renature rivers to reduce flood and drought risk Poland is reversing decades of river regulation—straightened channels and drained wetlands—that have worsened floods and droughts, shifting to renaturation and blue‑green infrastructure to restore natural water 7 sources. https://clstr.news/cluster/poland-moves-to-renature-rivers-to-reduce-flood-and-drought-risk ### 2026-07-25: Poniec municipality revamps silted pond into retention reservoir for new Berlinek estate Poniec, Poland is refurbishing a silted pond into a retention reservoir for the new Berlinek housing area, costing 184,500 zł with half funded by a regional environmental fund. 2 sources. https://clstr.news/cluster/poniec-municipality-revamps-silted-pond-into-retention-reservoir-for-new-berlinek-estate ### 2026-07-23: Poland revamps Starachowice reservoir and probes Piła lake decline Poland modernises the Piachy Reservoir in Starachowice with EU funds and sets up 11 piezometers at Lake Płotki in Piła to study its declining water level. 10 sources. https://clstr.news/cluster/poland-upgrades-piachy-reservoir-and-installs-monitoring-wells-at-lake-potki ### 2026-07-23: Poland expands water management measures amid drought and infrastructure upgrades Polish regions roll out new sewage, water‑use limits, river renaturation and retentive projects, while inspections crack down on illegal connections. 9 sources. https://clstr.news/cluster/polish-towns-advance-water-projects-to-improve-flood-control ### 2026-07-17: Polish Minister Hennig‑Kloska Announces Pending Permit for Gniezno Lakes Water‑Level Project Polish climate minister says a key environmental permit for a pipeline project to restore water levels in the Gniezno lakes is due soon, aiming to curb lake shrinkage and support local tourism. 2 sources. https://clstr.news/cluster/polish-minister-hennigkloska-announces-pending-permit-for-gniezno-lakes-waterlevel-project ### 2026-07-15: Polish towns roll out new water‑retention projects to boost flood protection Polish municipalities invest over €20 million in retention basins and lake upgrades to improve flood protection, while experts call for systemic water‑management reforms after the Bóbr River disaster. 9 sources. https://clstr.news/cluster/poland-advances-repairs-and-upgrades-at-racibrz-dolny-and-kaszownik-reservoirs ### 2026-07-10: Poland launches wetland and river restoration projects to boost water retention Lidl and WWF restore 30 ha of Polish wetlands to improve water retention and cut emissions, while Radom launches a 5 million‑zł river reconstruction to reduce flood risk. 2 sources. https://clstr.news/cluster/poland-launches-wetland-and-river-restoration-projects-to-boost-water-retention ### 2026-07-10: Polish towns build and renovate retention reservoirs to reduce flood risk Polish municipalities Stalowa Wola and Gmina Sońsk are building and renovating retention reservoirs to improve flood protection and climate resilience. 3 sources. https://clstr.news/cluster/polish-towns-build-and-renovate-retention-reservoirs-to-reduce-flood-risk ### 2026-06-30: Poland's Radom and Warsaw advance major water infrastructure projects Radom approves a large multifunctional reservoir for flood protection and recreation, while Warsaw recycles pool water for street cleaning, saving millions of litres each year. 6 sources. https://clstr.news/cluster/polands-radom-and-warsaw-advance-major-water-infrastructure-projects --- Cite as: Poland expands flood management, adds river renaturation.
