Overview
Muharraq Sewage Treatment Plant is an advanced facility on Muharraq Island, Bahrain, serving 400,000 people. It treats 100,000 m³/day using activated sludge with deep-bed filtration, with 95% capacity utilization.
Muharraq Sewage Treatment Plant is a major wastewater facility located on Muharraq Island in the Muharraq Governorate of Bahrain. It serves a population of 400,000 and is operated under a BOOT concession by Almar Water Solutions and Samsung Engineering, owned by the Ministry of Works. The plant employs advanced treatment using activated sludge with deep-bed filtration, achieving a high capacity utilization of 95% of its designed capacity of 100,000 m³/day. As an advanced treatment facility, it meets stringent standards for water reuse, aligning with Bahrain's water scarcity management strategies. All treated effluent is reused for landscape irrigation and aquifer recharge, contributing to groundwater conservation and reducing demand on freshwater resources. This reuse supports urban greenery and agricultural activities in the arid Gulf region, mitigating the environmental impact of wastewater discharge.
Environmental context
Bahrain is an arid island nation with limited freshwater resources, relying heavily on groundwater and desalination. The Muharraq plant's treated effluent is entirely reused for landscape irrigation and aquifer recharge, preventing nutrient-rich discharge into the surrounding marine environment. This practice helps protect the sensitive coastal ecosystems of the Arabian Gulf, including coral reefs and seagrass beds, from eutrophication and pollution.
