which is expected to double from 30 million gallons per day (mgd) to 60 mgd by 2060. The project is expected to be completed in Q3 2022. Pandan Reservoir Pearl's Hill Service Reservoir The Pearl's Hill Service reservoir was first mooted in 1897 to provide additional storage capacity and increase water pressure. The project is described in some detail in a 1902 newspaper report which highlighted the rapid growth in water demand from 4.1 million gallons per day (average) in May 1900 to 5.4 mgpd in 1902. Built of granite and concrete at a cost of $300,000, it was 70 feet higher than the Wilkie Road reservoir which it replaced. The work was undertaken by Municipal Water Engineer Robert Peirce (engineer) and his assistant L M Bell. Upon completion there were concerns reported in the newspaper about the construction quality, stability and leakages from the reservoir. The structure of the reservoir on top of the hill rather than sunken into the hill (like Fort Canning reservoir) appears to have been the root cause of the public concern. When filtered water was first imported from Gunong Pulau in Johor, beginning in 1929, it was stored in Pearl's Hill Reservoir. South End Reservoir The South End Reservoir is a small service reservoir located to the south of Singapore Changi Airport in Singapore. Rainfall from the runways and surrounding green areas is collected in the reservoir and used for fire-fighting drills and toilet flushing. The reservoir supplies 28–33% of the airport's water and saves the airport around S$390,000 per year. It is linked to the Changi Creek Reservoir to balance flows during incoming tides and high rainfall. Yishun Pond Park The pond in Yishun Pond Park is a service reservoir which acts as a water catchment area. References Changi Reservoirs in Singapore
