The municipal Government intends to increase the supply of water to the people of Semarang through a PPP project. The PPP scheme planned for the West Semarang SPAM project is to develop a clean water supply system with a capacity of 1,050 liters/second with a Build, Operate, Transfer project with a cooperation period of 25 years.

West Semarang SPAM is a SPAM development project planned as a SPAM pilot project with PPP funding schemes in Indonesia. West Semarang SPAM will solve the problem of the clean water crisis and land subsidence due to groundwater use in the city of Semarang. This project will use water from the Jatibarang Dam to resolve the problem of the lack of raw water supply in the city of Semarang, which has been relying on supplies from Kudus Regency.

The purpose of the project is to provide drinking water to 31 urban villages in 3 sub-districts with an estimated 60,000 families that have not been connected to the Drinking Water Supply System (SPAM) network in the West Semarang, Tugu, and Ngaliyan areas. This project is expected to resolve the clean water crisis and reduce groundwater use in the city of Semarang.
