The sewage treatment works that we operate are all licensed under the Water Pollution Control Ordinance, and some have additional control under the Environmental Impact Assessment Ordinance. Each month, self-monitoring results of the performance of the sewage treatment works are provided to the Environmental Protection Department for compliance check. In 2009, we achieved our target of full compliance of the license conditions.

During the construction of drainage facilities, three contractors were convicted of environmental offences in 2009. To promote responsible behaviour at our construction sites, DSD continued to operate the Construction Sites Housekeeping Award Scheme in 2009. All contracts that had an active construction period of six months or more within the assessment period (from January to October, 2009) were included in the Scheme. Each construction site was visited four times by senior or chief professional staff for assessment. The contractor and consultant/in-house site supervisory staff engaged in the contract were encouraged to work as a team to keep the site clean, tidy, hygienic and environmentally friendly.
