Cambodias capital Phnom Penh enjoys a beautiful setting on the Mekong. The river provides both transport and income for the city's one million population. Now another, unlikely, stretch of water - Beung Cheung Ek Lake which receives 80% of the city's sewage - is offering economic opportunities for three and a half thousand lower income families through the cultivation of the edible aquatic plant - Morning Glory - which is widely consumed by the city's expanding population.
