In the Colombian town of El Encano, municipal authorities warned that more than 200 tourism‑related businesses face closure unless a new wastewater‑treatment plant, costing roughly 10 billion pesos, is built to meet environmental court orders.
Río Negro’s government began upgrades on the Valcheta irrigation canal, installing 344 m of reinforced concrete to reduce seepage and improve water delivery for agriculture and local water supply.
The Buenos Aires province’s Directorate of Hydraulics, together with the municipality of Dolores, replaced gate leaves and installed counterweights on regional canals to improve drainage and prevent flooding.
Finally, in Peru’s Arequipa region, the Casa Grande dam construction is set to start on 30 November, funded through Obras por Impuestos by local firms, aiming to secure water for about 33 000 residents and support family agriculture in the Yura‑Yuramayo basin.
