Water & Sanitation Sector Working Group

13th September 2004

Water & Sanitation Issues Bangladesh Flood Emergency


Flood immediate impact on water sanitation
Flood – immediate impact on water & sanitation

  • 200,000 GoB tubewells plus maybe 1.8 million private wells underwater

  • Other water sources (ringwells, PSFs, underground RWH tanks, etc.) also out of action

  • Urban areas, esp. Dhaka – contamination through leaking pipelines & underground tanks, major city drainage problems, sewerage system inoperable, mixing of storm water & sewage

  • Sanitation facilities under water, collapsed – maybe 3 million latrines affected

  • Affected population with limited access to safe water and sanitary method for excreta disposal, especially in flood shelters

  • Major risks of diarrhoea outbreaks, possible major epidemic, such as cholera


Initial response to flood
Initial response to flood

  • GoB main response through DPHE – 14,252 tubewells raised, 93,790 tubewells disinfected, 824 new tubewells & 2,185 latrines installed in flood shelters. Financial support from UNICEF

  • DWASA maintained water supply in Dhaka as far as possible, including making free water available for bulk supply by NGOs (DSK, CARE, etc.) for distribution in slum areas

  • WPTs, bleaching powder provided by several agencies (UNICEF, WHO, UNFPA, NGO Forum)

  • NGO response in project areas by NGO Forum, CARE, WaterAid partners, etc.


Problems encountered
Problems encountered

  • WPT was not available in country – needed importing, process was slow

  • Access to flood affected areas to carry out disinfection, distribute WPT was difficult due to damaged transport system

  • Limited sanitation solutions in flood-affected areas. With concentration of populations in shelters, available land and buildings, few available latrines rapidly filled, plus open defecation inevitably occurred.

  • Water & sanitation facilities not planned for in many flood shelters, so had to be hurriedly installed once flood had hit

  • Too few trained tubewell mechanics


Post flood response short term
Post-flood response – short term

  • Continue disinfection programme for tubewells, including training of emergency tubewell mechanics.

  • Assessment of flood damage – underway at present, including water quality analysis with ICDDRB

  • Repairs to damaged water supply systems – tubewell repair and replacement, clean-up & repair of other technologies, esp. in arsenic affected areas. Clean-up of urban pipelines & repairs to damaged pumping systems

  • Replacement of damaged household latrines

  • Environmental clean-up


Post flood response longer term
Post-flood response – longer term

  • Mapping of shelter locations

  • Installation of improved water & sanitation facilities at suitable flood shelter locations – raised tubewells, RWH tanks, raised latrines

  • Review standard designs of tubewell platforms, latrines, etc., in light of floods

  • Review designs for, & choice of, safe water options in arsenic-affected flood-prone areas

  • Review emergency preparedness on annual basis, including stocks of emergency supply items such as WPT, water tanks, jerry cans, mini treatment plants etc.

  • Dhaka city – urgent need for improved urban planning and implementation, especially on drainage & sewerage


Organisation of post flood activities
Organisation of post-flood activities

  • UNICEF focal agency for UN Flash Appeal – expected to receive approx $5 million (DFID, Japan, German Natcom)

  • Key partners – DPHE, DWASA, NGO Forum, DSK (other NGOs under coordination of NGO Forum)

  • DPHE has prepared PCP for approx. $50 million
