Jos Water Services Corporation (JOWASCO) was established in 1975 to provide clean and reliable water services to the residents of Jos and its environs. The corporation's initial focus was on building the necessary infrastructure to meet the growing demand for potable water.

In 1985, JOWASCO expanded its operations to cover more areas in Plateau State. The corporation also introduced new water treatment technologies to improve water quality and distribution efficiency.

During the mid-1990s, JOWASCO faced challenges due to rapid urbanization and increasing population. To address these challenges, the corporation initiated several projects aimed at upgrading existing infrastructure and increasing water production capacity.

By 2005, JOWASCO had become a key player in the water sector in Nigeria, setting standards for water management and service delivery. The corporation also began focusing on customer service and launched programs to engage with the community more effectively.

In 2015, JOWASCO celebrated its 40th anniversary. The corporation marked this milestone by unveiling new water projects and renewing its commitment to providing sustainable water services. The corporation also embraced digital technologies to enhance its operations.

In 2023, JOWASCO launched a series of initiatives focused on sustainability, including water conservation programs and the adoption of renewable energy sources for its operations. The corporation continues to lead in water management and service delivery in the region.
