To enhance our water sustainability and meet growing water demand, PUB embarks on a variety of development projects each year. Environmental consideration is an important part of our planning and evaluation process, especially for infrastructure projects which are located within biodiversity areas.

PUB carries out detailed environmental studies on developmental projects where necessary, in accordance with the Urban Redevelopment Authority’s Enhanced Environmental Impact Assessment (EIA) framework, to determine and mitigate any potential impact on the environment. We keep our stakeholders in mind throughout the planning and project implementation process. Hence we also engage nature groups and community stakeholders throughout the entire Environmental Studies process.

Details of the various projects being developed by PUB are listed in the table below. Our environmental study reports are available for reference, and you may also provide feedback for each ongoing project, where available.
