Abstract

 

The threat of water scarcity and the progressing technology in sewage treatment plants promote the reuse of recycled wastewater. While the practice itself is beneficial, there are still issues to be solved to utilize its full potential. This study focuses on identifying the bottlenecks or limiting factors in implementing the practice on a building scale. An office building was researched to reveal its water usage pattern. The building introduces a sewage treatment plant so the sewage can be recycled into usable freshwater. The analysis indicates the produced recycled wastewater has not been fully utilized until now. While the volume of the water demand is greater than the recycled wastewater, several factors hinder the total utilization of the reclaimed water. The recycled wastewater is mostly more than enough to cover the water usage for both gardening and toilet flushing, the usages still leave an excess of water for other purposes. Because of the constraints in water quality, finance, and public reception, the excess reclaimed water is yet to be optimally utilized. Firstly, the quality of the reclaimed water is not very convincing to be used for non-flushing human usage and cooling towers. Secondly, the high cost of the investment and the overhaul of the plumbing system (for old buildings) deters the practice of reusing the reclaimed water. Thirdly, many people still have terrible perceptions about reused wastewater thus they would hesitate to utilize it even if the reused water is technically fine.
