BACAU

- 2 - PRESENT SITUATION

• Sewerage
• Several sections of large main collectors are in
  bad shape, collapsed and leaking
• Groundwater is lower than the sewers so
  exfiltration leads to groundwater pollution and
  high contamination risks
• Some areas are frequently flooded due to
  insufficient sewer capacity
• One of the neighbourhoods across the river uses
  a wastewater pumping station that needs urgent
  rehabilitation.
• No investment in sewerage in MUDP2.

- 2 - PRESENT SITUATION

• Waste Water Treatment Plant
• The plant can treat only 50 of the incoming
  flow the rest is send directly to the
  Bistrita River
• Siret River
• The treatment efficiency is less than 36
• The inlet works are not functioning properly -
  40 efficiency
• The biological treatment is way below EU and
  national standards - 25 efficiency
• The sludge management is not proper.

- 2 - EU DIRECTIVES

• The measure is intended to cover for 240,000 PE
  for compliance with EU Directives
• surface water quality 75/440/EEC
• urban waste water 91/271/EEC
• hazardous waste 91/689/EEC
• civilised sewerage for 180,000 inhabitants

- 3 - PROJECT DESCRIPTION

• rehabilitation of the Bacau sewerage system -
  applying to the damaged sections of the trunk
  mains
• rehabilitation of a wastewater pumping station
• rehabilitation of the Waste Water Treatment Plant
  to fully treat the incoming flow at required
  parameters
• introduction of a proper sludge management

• For the sewer rehabilitation
• direct - 180,000 inhabitants connected to the
  main sewers to be rehabilitated
• indirect - 220,000 inhabitants of the city by
  decontamination of groundwater

• For the WWTP
