Study
on septic tanks impact
The Environmental
Protection Department has just commissioned a study to investigate
the impact of septic tank discharges on the receiving environment
in order to prevent potential pollution problems caused by
the increasing number of small scale housing developments
in unsewered areas.
The consultancy study will be conducted by Montgomery Watson
Hong Kong Ltd and is expected to be completed within 18 months.
It will cost $2 million.
Principal
Environmental Protection Officer, Dr Malcolm Broom said: "Septic
tanks and soakaways are the most commonly adopted on-site
sewage treatment and disposal systems for small scale housing
developments in unsewered areas.
"Such
systems if not sited, designed, and operated properly can
give rise to serious pollution problems.
"The
study will assess the impact of effluent discharges from septic
tanks on the aquatic receiving environment, and the consultants
will make recommendations on appropriate management and control
strategies for septic tank systems," he said.
