Ajyal Sewage Treatment Plant, Al Khobar, Eastern Province, Saudi Arabia

Ajyal Sewage Treatment Plant is an operational wastewater facility located in Al Khobar, a major city in Saudi Arabia's Eastern Province along the Arabian Gulf coast. The plant serves the local population as part of the region's municipal wastewater infrastructure, supporting urban and industrial water management needs. As a Saudi Arabian facility, the plant operates under the country's national wastewater regulations, which align with Gulf Cooperation Council (GCC) standards for effluent quality and environmental protection. For agglomerations of this scale, secondary treatment is typically required, with advanced treatment applied where water reuse is prioritized. The plant's treated effluent ultimately discharges into the Arabian Gulf via local drainage systems. The coastal waters of the Eastern Province support diverse marine life, including coral reefs and fisheries, making proper wastewater treatment essential for protecting these ecosystems and maintaining water quality for recreational and economic uses.

The plant's treated effluent flows into the Arabian Gulf, a semi-enclosed sea connected to the Indian Ocean. The coastal waters of the Eastern Province host sensitive marine habitats, including seagrass beds and coral communities, which support commercial fisheries and biodiversity. Effective wastewater treatment is critical to prevent nutrient loading and protect these ecosystems from degradation.
