A booming plastic container market around the Saris area bustles with shoppers inspecting the selections. Water supply shortages have plagued the capital as an expanding population size's demand is unmet by the drops moving through the pipes. The Addis Abeba Water & Sewage Authority relies heavily on underground wells and surface water from the Legedadi, Dire and Gefersa dams. With the Authority digging 28 wells to meet the demand shortage, several parts receive water through the taps three days a week at most. A growing number of urbanites procure the services of water trucks that sell underground water sourced from the outskirts of the capital.
