Case Study: Sustainable Toilet in TaikooHui, Guangzhou

This article is part of a series of selected ESG case studies submitted by participants in the 2017 GRESB Real Estate Assessment.

The installation of Eco-Toilet can greatly reduce the water consumption for flushing and to minimize the impact on the environment, especially on marine pollution.

Purpose of the project

Adopting the appearance of a grotto, the sustainable toilet intends to offer visitors “a contemporary abstraction of nature” experiencing water-saving approach in toilet experiences and to raise environmental awareness in the public realm.


We installed low flush water toilets and water-free urinals in the male bathrooms in TaiKoo Hui, Guangzhou. Bathroom faucets are equipped with energy efficient hand dryers, eliminating paper use altogether. In addition, a grey water system designed to collect wastewater from sinks for reuse as flush water in the toilets is used.


This sustainable toilet concept applied in the male bathrooms in TaiKoo Hui, Guangzhou. Plans are currently underway to install similar upgrades in the women’s bathrooms at TaiKoo Hui, Guangzhou.


The new toilets can reduce the volume of flush water by 5-8 litres per flush as compared to conventional toilets, and the water-free urinals are expected to save approximately 150 cubic metres of water annually. With this new system, we target water savings of 1,080 cubic metres annually.
