Established in 1989, DSD is one of the eight departments under the Environment, Transport and Works Bureau. As at March 2004, the Department had 1,911 staff.

A Safe Workplace
We place the highest priority on safety and health at work. To ensure our staff are well protected when performing daily duties, we have implemented various safety measures and organized training courses and seminars on occupational health and safety for staff. In order to promote good housekeeping at our sites for the protection of our staff as well as the community, we also launched a departmental-wide "Construction Sites Housekeeping Award Scheme" in January 2004.

We actively participate in charitable activities to help the needy groups. The activities that the department has participated in 2003-04 includethe Community Chest's Green Day, Dress Casual Day, Skip Lunch Day, DSD Charity Walk, Sower's Action Challenging 12 Hours Charity Marathon, Oxfam Trailwalker etc. Our Volunteer Team has also organized and participated in a number of service events in 2003-04, such as visit to the Precious Blood Children's Village, collection of second-hand English books and toys for needy children, Oxfam Rice sale and Scarf-knitting
