Problem statement: Water tanks in Singapore are compartmentalised, and each building has a single tank which has internal partitions to ensure constant water supply to buildings even during cleaning and maintenance. However, building occupants experience temporary water disruptions as compartmentalisation problems create water leakages, resulting in having the entire tank being shut off in order to carry out works. Therefore, instead of having multiple compartments in a single tank, multiple tanks are needed to supply water reliably.
Purpose statement: The aim of this report is to propose to the Housing Development Board (HDB) the implementation of two water tanks connected in parallel to supply water to each building, so as to eliminate the use of unreliable compartments while maintaining redundancy. This will reduce the occurrence of water disruptions and improve the reliability of water supply.
