Samoa: Sanitation and Drainage Project Supplementary Loan

Sovereign Project | 28314-023

Summary

The overall objective of the Project is to help improve Apia's environment and public health through improved drainage and sanitation infrastructure and capacity in urban management. Project objectives include (i) improved public health, (ii) improved environmental quality, (iii) improved surface and groundwater quality, and (iv) reduced frequency of flooding in specific low-lying areas. The Project also promotes private sector participation in the provision of urban services through the outsourcing of certain utility services to the private sector and further promotes private sector development through provision of improved urban infrastructure and environment for businesses.

Project Rationale and Linkage to Country/Regional Strategy

World Bank data for 2005 indicate that 100% of Samoa's population has access to improved sanitation facilities. The statistics for access to sanitation misrepresents the public health implications of the sanitation status of many living in the urban areas. In urban Apia which has a population of approximately 60,000, 75% of households have septic tank systems, but many are too small, rarely cleaned, and sometimes directly linked to the nearest drainage channel, polluting groundwater, surface streams, and the harbor. In the central business area (CBA) and special needs areas (those with special wastewater concerns) such as hospitals and major school compounds, less than 10% of wastewater is adequately treated. The hospital has a poorly operating treatment plant, as do most commercial centers and government complexes. Others have inadequate septic systems. The situation is exacerbated by the historical lack of urban management and the absence of effective town planning. Draft drainage or wastewater management plans have only recently been completed. Individuals have elevated their plots heights, reclaimed land in the mangrove area, and blocked drainage channels. The effect is a haphazard and cumulative nonfunctioning drainage system. Flooding after heavy rain is exacerbated and foul water flooding poses a health risk due to septage and latrine wastes being released to the surface environment.

Nearshore marine water and urban stream-water quality in Apia has been significantly degraded due to inadequate sanitation and wastewater management systems. Water quality monitoring data, which have been only intermittently collected, show definitive evidence of sewage contamination as evidenced by low dissolved oxygen saturation, high biochemical oxygen demand (BOD), high total nitrogen concentration, and high indicator bacteria concentration. Urban drains are often choked with litter and vegetation, foul smelling (indicating anaerobic conditions), and contain floating oil and sewage. Drains and natural watercourses are contaminated with sewage and, occasionally, industrial waste. Monitoring is done infrequently and usually initiated through donor-funded activities, including Asian Development Bank (ADB)-supported TAs.

Severe floods were reported in 1939, 1975, 2001, May 2003, and more recently in February and November of 2006. Minor localized flooding occurs frequently. The 2001 flood was particularly severe, estimated to have damaged some 1,300 buildings. Residential and commercial properties were flooded leaving a layer of mud when the water abated. In the low-lying areas, residents were forced to evacuate to higher ground. Stock and equipment were damaged and many businesses and schools were forced to close to clear up damage for up to several days. Traffic congestion and road damage from the mud and debris were severe, particularly near Fugalei Market. More than 28,000 people were affected by water cuts resulting from damage to water supply infrastructure. Some businesses not directly affected by the flood were forced to close because of the water supply cut. The estimated repair bill exceeded SAT11 million (US$4.3 million). Data for damages resulting from the 2006 is currently unavailable.

Impact High standard of environmental quality and public health in Apia.
Project Outcome
Description of Outcome Effective and sustainable sewage collection and treatment systems, and less frequent and severe floods in Apia, through the provision of adequate wastewater and drainage infrastructure, and effective wastewater and drainage planning and management.
