Africa Water Week --nearly one billion people around the world have no access to drinking water，that lack of clean water association with un-proper hygiene and shortage of toilets kills 3.3 million a year．And this is a common problem in many parts of the developing world，but its effect is not widely known，according to experts at the Pulitzer Center on Crisis Reporting．
   As part of the World Water Day tradition，the center is screening films about international water issues at the Environmental Film Festival in Washington，D．C．The films describe a variety of conflicts over water．
   "The challenge in presenting these films，" says Peter Sawyer，project coordinator at the Pulitzer Center on Crisis Reporting， "is to share with a wider audience the urgent issues surrounding water．" "Our goal for this screening is to just get these issues out there，" he says． "We don't feel that they attract public attention and we think that they should because they are really important．"
   In Dhaka's Challenge，filmmaker Stephen Sapienza explores one of the fastest growing cities in Asia．He says one-third of the 15 million people in the Bangladeshi capital live in places where safe water is limited．Each year 400，000 newcomers join Dhaka's urban poor．City water from Dhaka's Water and Sewer Authority （WASA） comes at a price，available only to land owners．The film records how a non-profit group helped change the law to give the same equal water rights to the urban poor．
   Diabalok Sing Ha，who is the group's founder，said， "A win-win situation actually occurred because Dhaka WASA wanted their incomes and on the other hand，poor people wanted the service and they immediately see the economic advantage of getting Dhaka WASA water supply because that is cheap，so they immediately buy in．"
   "My story was just trying to point out that these problems are solvable on some level even if you have to start small and it's possible in the long run to save many lives，" says Sapienza．
