Introduction

The proposed Ecuador Guayaquil Wastewater Management Project (“the Project”) involves four main components as follows: 1) Installation of Household Connections; 2) Rehabilitation of Sewerage Network; 3) Wastewater Treatment Plant and Disposal Facilities; and 4) Project management and administration, including communication plan and management of social, environmental, and safety issues. These components are described in more detail below.

The overall Project impact is expected to be positive due to the improved effluent quality that will be discharged into the Guayas River and the reduction of untreated wastewater that is presently leaking from the existing sewer system and affecting shallow ground and surrounding surface water bodies, like the "Salado" Estuary.

The proposed Project has been classified by the World Bank, per OP/BP 4.01, as an Environmental Category A due to the type and size of the Project Component Three, the construction of the WWTP. This Component requires the expropriation of a 40.74ha area which is host to one resident, a radio antenna and a shrimp production facility. Because expropriation has been taking place prior to World Bank engagement a Remedial Resettlement Action Plan has been prepared, which when implemented, will ensure the expropriation process is in conformity with the World Bank’s policy on involuntary resettlement. Related to Component Three, an Environmental and Social Impact Assessment (ESIA) has been developed by an international consulting firm1 with the support of a local environmental consulting firm2, under supervision of the Empresa Municipal de Agua Potable y Alcantarillado de Guayaquil (EMAPAG EP). The remaining sections of this document present an executive summary of the March 2015 ESIA for Component Three prepared by the mentioned consulting firms.

Project financed works in Component Two have relatively moderate potential negative environmental impacts and can be readily mitigated with standard measures, and even less impacts are associated with works in Component One. For Components One and Two, an Environmental and Social Management Plan (ESMP) was developed for each component and includes an assessment of potential impacts and proposed mitigation and monitoring measures. Component One will finance the installation and rehabilitation of household connections in specific areas of the City of Guayaquil, where household toilets discharge directly to the estuary or to reportedly poorly constructed and maintained pits or septic tanks, which contributes to the degradation of the Estero Salado. The works involve establishing a connection from an existing sewer line on the street to a house, and the potential environmental impacts are relatively minor. Component Two involves the rehabilitation of the sewerage network in “La Chala” basin and will improve sewer efficiency by reducing infiltrations and contribute to the reduction of the contamination of the Salado estuary from domestic wastewater. The works should have relatively minor to moderate potential negative environmental impacts during construction (for example, generation of noise and dust, minor traffic disruption, disposal of waste) and can be readily mitigated with standard measures established in the ESMP. Even less impacts are associated with works in Component One. The ESMPs include a “chance finds” procedure and natural habitat protection measures to be used if needed given the proximity to the works and the Guayas River and the Salado Estuary. The draft ESMPs for Components One and Two were disclosed and consulted in January 2015, and

Project Components

1. Component One: Installation of household connections (US$18 million, with US$2.8 million of IBRD loan financing). This Component will finance the installation and rehabilitation of household connections in specific areas within the southern districts of the City of Guayaquil.3 These districts are equipped with a dense sewerage collection network which, although requiring rehabilitation of main collectors to reduce infiltration, reaches and could serve almost all inhabited areas. Nonetheless, despite a broad network coverage, just 82 percent of the households in the area are currently actually connected to the system. Most of the remaining 18 percent (around 30,000 families) are poor households located in Suburbio Oeste, Isla Trinitaria, Sector Guasmo and Casco Central sectors, which are riparian areas of the Estero Salado estuary, where household toilets discharge directly to the estuary or to reportedly poorly constructed and maintained pits or septic tanks, which contributes to the degradation of the Estero Salado.4 Although many houses have a sewer passing in front, these households have not been connected—despite a legal mandate to do so—mainly because of the cost of the connection fee.5 Under the Project, household connection costs—including the cost of required indoor works like piping, flooring, and others—will be partially subsidized and financed by EMAPAG EP (clients will pay EMAPAG EP the nonsubsidised segment in installments through the water bill). In parallel, a communication campaign will be launched to inform the beneficiaries about the initiative and its benefits and to promote improved hygiene and maintenance practices required to ensure the proper functioning of the condominial sewer system. The design of this Component has been developed based on previous successful experiences with connection campaigns led by EMAPAG EP, which managed to increase effective access to piped sanitation up to 98 percent in other districts of the city with high poverty rates.6

2. Component Two: Rehabilitation of sewerage network (US$37 million, 100 percent financed by IBRD). This Component will finance the rehabilitation of the sewerage network (including sections of the primary, secondary and tertiary network) in La Chala basin (Suburbio Oeste area), which, as stated above, is riparian to the Estero Salado estuary. The main collectors in this area have been identified to require urgent rehabilitation to reduce wastewater losses and enable their effective collection function. This Component of the Project aims at reducing

3 With regard to the potential minor expansion of the secondary and tertiary networks which might be required in specific neighborhoods within the area to enable the installation of household connections, EMAPAG EP has agreed to include these within Interagua’s annual network expansion targets. This will require coordinated planning with Interagua based on a plan for the connection of the different neighborhoods, which is already under preparation by EMAPAG. 4 To address the problem of domestic discharge coming from neighborhoods which are riparian to the estuary on the northern side, there are three ongoing projects managed by EMAPAG EP to connect around 25,000 households to the sewerage network currently under implementation. These projects, which combined the household connection component financed by the proposed project and the Guayaquil Ecológico program jointly financed by the GoE and the municipality of Guayaquil, are jointly expected to completely eliminate domestic discharge to the estuary. 5 This cost is US$500 and includes the cost of emptying and sealing of the septic tank or other on-site sanitation solution. 6 Once home owners in a specific neighborhood have agreed to be connected to the sewerage network, a contractor hired by EMAPAG EP will carry out the installation in close coordination and consultation with each home owner. Once the work is finished, the home owner will sign a certificate that they are satisfied with the works constructed and acknowledge their connection to the service. infiltrations in the south sewerage subsystem, thus contributing to reduction in the contamination of the Estero Salado estuary from domestic wastewater. It is estimated that of the total volume of wastewater collected and pumped in the pumping station of La Chala, approximately 25 percent corresponds to ground water infiltration,7 which also increases wastewater pumping and treatment costs. Also, some segments of the Suburbio Oeste sewer network that are meant to function as gravity mains get pressurized during periods of high tide, which again suggests a high infiltration rate.

3. Component Three: Wastewater treatment and disposal facilities (US$161 million, with US$58.5 million of IBRD loan financing). This Component will finance the construction of a new WWTP, called Las Esclusas WWTP, and associated pumping and transmission facilities to treat 100 percent of the wastewater collected in the southern districts of the city of Guayaquil within the design year of 2045. Wastewater generated in the south subsystem is currently collected in two sewer mains: (a) the Guasmo sewer main, which conducts an average flow in dry weather of 0.60 m3/s into the Guasmo H pumping station from where wastewater is pumped directly into the Guayas River through a 180 m long pipeline and an underwater outfall diffuser, and (b) the Parson’s Sur sewer main, which conducts 2.10 m3/s in dry weather into the La Pradera pre-treatment station (equipped with a mechanized pre-treatment, a disinfection system that is presently out of service and a underwater outfall diffuser). Therefore, wastewater is currently discharged into the Guayas River with very little or no treatment, failing to comply with the contaminants concentration thresholds established in the National Norm on Environmental Quality and Effluent Discharges (NCADE in its Spanish acronym).8 To address this situation, EMAPAG EP will construct, through this Project, a new WWTP, Las Esclusas WWTP, near the current point of discharge of the Guasmo sewer main, which will treat all the sewerage collected in the south subsystem.

4. Different technological alternatives for the wastewater treatment were analyzed by EMAPAG EP before the Bank’s involvement to develop the design of the treatment facility and these were discussed with the Bank during preparation. The Chemically Enhanced Primary Treatment (CEPT) option was retained after an alternative analysis was conducted since it will allow the municipality of Guayaquil to consistently meet the national regulatory authorized limits set for the Total Suspended Solids (TSS) below 100 percent and BOD below 100 percent and all other pollutant concentrations. CEPT is also considered a flexible technology which can easily be adapted to changes in influent operating characteristics or potential future stricter standards. The feasibility study commissioned by EMAPAG EP included a thorough analysis of 19 secondary treatment process alternatives, including aerobic and anaerobic processes,9 and there is sufficient area and several options to install secondary treatment in the future.

7 The storm drainage and sewerage systems are separate systems but there is infiltration of rainwater into the sewerage system due to the poor conditions of the network.

8 The NCADE sets the maximum limits for effluent quality standard at: BOD5 = 100 mg/L; SST = 100 mg/L; Total coliform =100 NMP/100 ml. The effluent discharged at Guasmo H does not comply with these limits as BOD and TSS concentration in the raw wastewater is very high. The effluent discharged at La Pradera does comply with the NCADE most of the time, given the high dilution of the water that arrives into the facility due to ground water infiltration into the sewerage system.

9 The secondary treatment alternatives analyzed had 19 processes, including aerobic and anaerobic solutions. The trickling filters process was selected as the most cost-effective and preferred option for secondary treatment. 5. Component 4: Project management and administration, including communication plan and management of social, environmental, and safety issues (US$5.4 million with US$4.2 million of IBRD loan financing). This Component will finance activities associated with overall project management by EMAPAG EP, including Project-related audits, monitoring and evaluation, equipment and training to strengthen the implementing entity, as well as individual consultants. It will also include support to EMAPAG EP related to the planning and management of environmental and social issues and safeguards. Specifically, this Component will fund: (a) a study to set up a system for the physiochemical, bacteriological, and limnologic monitoring of the Guayas River water quality;10 (b) a study to set up a system for the physical-chemical, bacteriological, and limnologic monitoring of the Estero Salado estuary water quality in relation with Project Components One and Two; (c) a master plan for the management and final disposal or reuse of the bio-solids which will be produced at the Las Esclusas WWTP and other planned WWTPs (Los Merinos, Asuncion City, and others); (d) communication campaigns and technical assistance for community development and training; (e) a Project Impact Evaluation (IE); and (f) an integrated urban water management study for the planning of development and infrastructure in a growing flood-prone area of the city of Guayaquil (Sistema Tres) which requires interventions in urban drainage and wastewater management.

10 The scope of this study is to be defined during project preparation and the objective is to enable monitoring of the Guayas River water quality at different points, which in turn will enable measuring of the benefits of the Las Esclusas WWTP and other future treatment plants on the water quality of the Guayas River.
