The Group strives to render good maintenance services to its rental properties so as to enhance the building life span for avoiding early demolition that leads to resources wastage. Contractors had been encouraged to use non-toxic and environmental-friendly materials in carrying out maintenance and repair works. Many blocks of the Group's residential and commercial buildings have been awarded the Certificate of Fresh Water Plumbing Quality Maintenance Recognition Scheme launched by the Water Supplies Department as a token of recognition that high quality fresh water is supplied to Tung Wah's tenants.

Some of the Group's properties have taken part in the Programme on Source Separation of Domestic Waste organized by the Environmental Protection Department (EPD) by placing waste collection bins on each of all residential floors to facilitate collection of waste paper, metals and plastics from tenants. Monthly reports on the weight of waste collected for recycling are submitted to the EPD for compilation of statistics in support of environmental protection. In addition, boxes have been placed in the Group's buildings to collect rechargeable batteries for environmental disposal.
