Problems of the Operation when managing Sewage
and Wastewater Treatment Plant

• - So far there are no wastewater treatment
  plants in our country, the outlets of the primary
  sewer network are into storage basins in Phnom
  Penh which are used as treatment plants.
• - The problem of storage basins mainly lies with
  thier progressire filling by silt and other
  solids brought in through the combined sewer
  system, direct runoff on street surface during
  flooding and sludge from septic tanks.

7

• - Municipality wastewater is primarily disposed
  of through a network of sewage drainage pipes
  that empty into retention basins known as Beong.
• - The wastewater in the basin is later pumped
  into rivers and lakes. In Phnom Penh, for
  example, there is a network of sewage/drainage
  pipes and 11 pumping station covering the 6 main
  catchment areas Beong Trabek, Beonk Salang, the
  Khmero Russian Hospital vicinity, Daun Penh New
  front of Basac, and Toul Kok.

CONSTRUCTION AND OPERATION OF SEWAGE

• Sewage and Wastewater Treatment Facility
• - Sewer network had been constructed until the
  end of 1960s with city development during this
  period, numerous channels and ditches were filled
  up and converted to sewer pipes.
• - The sewer network is now managed by DPWT.
• - The existing combined drainage and sewerage
  system consists of 150km of pipes network. 9km of
  canals, 4 retention basin and 11 pumping station,
  and covers 24km2 of inner dike area in Phnom
  Penh. The Drainage and sewerage system, due to
  absent of regular maintenance for 25 year, is in
  a bad condition and needs urgent attention.

11

• - Drainage and sewage Division of DPWT is in
  charge of operation and maintenance of the
  drainage pumping stations in the municipality of
  Phnom Penh.
• - Major repair of equipment in dry season.
• - Daily operation records includes the number of
  installed pumps, water level at pumping station.
• - Operation time (Start , End )

TO PROMOTE THE COOPERATION BETWEEN CAMBODIA AND
KOREA
We think that the - Korean Government
should send more investors to invest in
Cambodia. - Korean Government should send
technical assistants to help Cambodia,
especially in Phnom Penh.
- Korean Government should increase
the number of participants undertaking
training course about environment.
18
EXPECTATION FROM THE COURSE
- We had known about new technology in Korea
to improve their country. - We hope that
after finishing this course we can get more
experience on high technology to improve
our work in the country. 012 553 176 Sarey Vuth
