Barbados is poised to revolutionize its agricultural sector through a landmark infrastructure initiative designed to convert sewage into a sustainable irrigation resource. The Climate Resilient South Coast Water Reclamation Project, a five-year development program, will provide treated wastewater to farmers at government-regulated prices, potentially reducing irrigation expenses significantly.
Government officials confirmed that pricing structures for reclaimed water would be determined at the ministerial level, separate from the Barbados Water Authority’s purview. Current rates have already decreased from $1.80 to $1.00 per unit in recent years, with further reductions anticipated once the new system becomes operational.
Technical specifications reveal an advanced multi-stage purification process beginning with mechanical screening to remove solid debris. The wastewater will then undergo biological treatment, particle filtration, and reverse osmosis purification—utilizing technology similar to the Spring Garden desalination facility—to achieve the Ministry of Agriculture’s strict standard of 450 milligrams per liter of total dissolved solids.
Dr. John Mwansa, Technical Adviser for the Barbados Water Authority, emphasized the climate-resilient design elements: “The new treatment plant is being constructed four meters higher than existing facilities as protection against storm surges and rising sea levels.”
The comprehensive system includes a 25-kilometer transmission pipeline extending along the ABC Highway toward St. George Valley, with ultraviolet and chlorine disinfection preventing biological growth within the distribution network. During rainy seasons when irrigation demand decreases, excess treated water will recharge aquifers through five injection wells, creating sustainable water reserves.
Additional project components involve drilling new boreholes at Gibbons Boggs and upgrading the Bridgetown Sewage Treatment Plant to supplement water supplies toward the Botanical Gardens region. The Barbados Agricultural Development and Marketing Corporation will manage distribution through existing irrigation networks, though farmers won’t receive reclaimed water until construction concludes in approximately five years.
