SPLASH is the concessionaire appointed by the Selangor State Govenrment to develop SSP3 on a Build, Operate and Transfer (BOT) basis. The main components of the scheme are the construction of the Sungai Selangor Dam, the realignment of the Kuala Kubu Bharu – Fresers Hill Road, and the construction of the Rasa and Bukit Badong water treatment plants. Upon completion, SPLASH is required to operate the dam and treatment plants for the duration of the 30 year concession, commencing from January 2000.

SPLASH is also the concessionaire for the Sungai Selangor Water Supply Scheme Phase 1 (SSP1) which it operates and maintains. SSP1 is a project in Bukit Badong initiated by the Selangor State Govenrment and it commenced operations in 1993. It was handed over to SPLASH in 2000 under the same concession as the SSP3.
