Waste water services in a shopping center include restrooms, shops, food areas, restaurants and the public market. Wet stalls, semi-wet stalls and carinderia or eateries contribute to the majority of the waste water from the market. High Biochemical Oxygen Demand comes from unconsumed food. Cleaning operations in the meat, poultry and fish sections also contribute to waste water. As with solid waste, the LGU must demonstrate that sufficient drainage exists to handle the additional waste water generated by the project.
