At the middle of the 90s, Espirito Santo's urban water supply coverage level had reached about 87%. However, the increasing discharge of raw domestic wastes into the rivers has degraded the fluvial water quality, which serves as water supply sources. Also, a widespread coastal pollution has been observed since. The increasing level of water pollution is still a permanent cause of water-borne diseases and infant mortality. On June 28, 1994, the World Bank approved a US$154 million loan to the State of Espfrito Santo for the Espfrito Santo Water and Coastal Pollution Management Project (Loan 3767-BR). Loan 3767-BR closed on 30 June, 2003 having disbursed just under US$112.5 million and only partially achieved the water and sewerage coverage and institutional development targets established at appraisal. Locally, the project changed names under successive State Governments (it was referred to locally as "PRODESPOL" between 1994 and 1999 and "PRODESAN" between 2000 and 2003). The State Government in office since January, 2003 has now requested an additional World Bank loan in the amount of US$36 million to complement the activities carried out over the past 9 years in order to reach the project's original development objectives. This new phase of the project is referred to locally as the "AGUAS LIMPAS project", though it, like its predecessors (PRODESPOL and PRODESAN) carries out activities identified and appraised under the integrated Espirito Santo Water and Coastal Pollution Management Project. Additional financing for this existing project seeks to guarantee that the resources already allocated are optimized and that the expected economic, financial, social and environmental results are consolidated. The remainder of this document uses the local nomenclature (PRODESPOL "project", PRODESAN "project" and Aguas Limpas "project"). Executive Summary 3 Espirito Santo Waters and Coastal Management Project: Aguas Limpas Project This report is structured as follows: * Section 2 gives an overview of the public administration in Espirito Santo State concerned by the World Bank Contract BR-3767; * Section 3 describes the sanitation systems implanted by PRODESAN and its impacts in the sanitation system in Greater Vitoria; * Section 4 gives a description of the proposed Aguas Limpas Project as a complement to PRODESAN Project; * Section 5 gives a environmental characterization of the project areas; * Section 6 makes an environmental evaluation of the PRODESAN and Aguas Limpas Projects; * Section 7 gives a description of the institutional strengthening activities proposed to IEMA ( Environmental Control Institute) and CESAN (State Water Company); * Section 8 proposes an Environmental Management Plan as a complement to the activities mentioned above; and finally, * Section 9 describes the two public consultation recently promoted by the state government to present and discuss the Aguas Limpas Project. 1.2 Public Administration in Espirito Santo The principal actors in the political -administrative structure of Espirito Santo, with respect to the World Bank Contract BR-3767 are: i) SEPLOG: the Department of Planning, Budget and Administration; ii) SEAMA: the Department of Environment and Water Resources; iii) CESAN- the Espirito Santo Sanitation Company; and iv) IEMA - the State Environmental Institute. CESAN was created in 1967 and is a mixed state-private corporation in which the state government has a majority in voting stock options. CESAN operates in 52 of the state's 78 municipalities. Prior to the PRODESAN project, the company provided Executive Summary 4 Espfrito Santo Waters and Coastal Management Project: Aguas Limpas Project treated water to 1,765,653 inhabitants and sewage connections to 378,403 inhabitants. IEMA, created in 1988, is an autarky with administrative and financial autonomy whose mission is to protect the environment and the management of water resources in the state, from a perspective of sustainable development with social justice. During 2003, Espirito Santo promoted significant institutional advances on environmental issues, reactivating the State and Regional Environmental Councils (CONSEMA and CONREMAs) and the State Water Resources Council (CERHG). The inauguration of the PRODESAN public works in 2003 initiated the environmental recuperation of the Vitoria Bay, of the coastal region of greater Vitoria and of the principal water sources that supply the capital and nearby municipalities (the Santa Maria da Vitoria and Jucu Rivers). 1.3 The Sanitation Systems Implanted by PRODESAN Public works implanting sanitation systems, inaugurated in the final days of 2003, will result not only in an improvement in the population's quality of life, but also in a substantial reduction in pollution, leading to an indisputable gain for the environment. Prior to PRODESAN, the PRODESPOL project (1994-2000, financed also by the World Bank) initiated the implantation of sanitation systems in the municipalities of Greater Vitoria. At that time, part of these systems was executed, with emphasis on wastewater collection. In 2001, PROEDSAN elaborated a single Turn-Key contract to put into operation part of the works that had been implanted by PRODESPOL, and to build four sewage treatment plans in the metropolitan region. The contract's strategy, using the Turn- Key mechanism, was a very successful experience, fully reaching its objectives and correcting the main errors identified during the PRODESPOL project. The system was completely implanted and currently is in operation. Executive Summary 5 Esptrito Santo Waters and Coastal Management Project: Aguas Limpas Project The PRODESAN project also constructed the Domingos Martins Sewage Treatment Plant, using previously existing sewage collection, freeing this mountain municipality from a large level of pollutants that were degrading the region's rivers.

The number of people benefited with sewage treatment grew from zero to 2,405 in the city of Domingos Martins. In Vitoria, there was an increase of 124% in the number of people benefited with treated sewage. In Cariacaica, Vilha Velha and Guarapari the increase was even greater, 392%, 626% and 333% respectively.

The gravity sewers and transmission mains of the implanted systems are not completely operating. That is, in the urban areas of these systems there are areas: Executive Summary 9 Espfrito Santo Waters and Coastal Management Project: Aguas Limpas Project - with full implantation (operating networks) - with inoperative networks, requiring complementation - that are unattended. The implantation of networks in the entire urban area will increase significantly the sanitation services in these regions, leaving however some treatment plants working over capacity and others with excess capacity. The program of joining the system finds itself at the beginning of 2004 in development, and must be increased in the immediate future. However, to evaluate the over capacity and idle capacities of the existing treatment plants, we presumed the program to promote increased domestic sewage collection to be concluded.

Bandeirantes and Araghs I Cariacica and Vila Veiha Treatment Plants These two plants, built by PRODESAN, have the capacity to fully attend the population foreseen in the Aguas Limpas Project, without requiring any expansion. The Ara9as system will have substantial excess capacity (33,536 inhabitants) while the Bandeirantes system will have a residual capacity of 5,443 inhabitants. Aeroporto I Guarapari Sewage Treatment Plant The Aeroporto Treatment Plant, also built by PRODESAN does not have the capacity to attend the population foreseen in the Aguas Limpas Project. Therefore, a study should be conducted for a specific treatment system, which could be obtained through the expansion of the Aeroporto plant or with the construction of another plant elsewhere. Executive Summary 1 DATES FOR THE WORKS HORIZONS OF GREAT VITORIA SANITATION SYSTEM 1.4 Complementary System of PRODESAN: The Aguas Limpas Project The Aguas Limpas Project is not only a proposal to expand sewage collection and treatment services. It also intends to expand state action on environmental and water resources issues more generally, leading to governmental actions of environmental quality recuperation, according to the below table. Utilization of installed capacity of sewage treatment plants Since the existing construction and equipments in pumping stations and sewage treatment plants have excess capacity, it is possible to increase the sewage network. In doing so, the existing system will be optimized, improving as well the quality of life of the population and promoting substantial pollution reduction, with important gains for the environment. Expanding coverage of sewage services Some regions of Greater Vit6ria that are not benefiting from the PRODESAN projects would obtain their own sewage treatment installations. This is the case of the following locations: Manguinhos, Nova Almeida, Praia Grande, Guarapari-Centro, Jucutuquara and Viana-Sede. Improvements in Water Supply Security The security of the water supply system in Greater Vict6ria depends on the implantation of reservoirs in the following places: (1) Santa ClaraNVit6ria; (2) PedreirasNit6ria; (3) GarotoNila Velha; (4) Araq,csNila Velha; and (5) Morro do Pico/CariacicaNiana. In addition, some improvements in the potable water production systems are needed in Carapina/Serra, CacarocaNila Velha and Guarapari, as well as the implantation of aqueducts in the lges-Boa Vista/Vila Velha section and the Planalto-Civit-Serra/Serra sections. Institutional Strengthening of CESAN and IEMA The operational and financial strengthening of CESAN will promote the reestablishment of its self financing capacity, expanding investments, with a multiplier effect on employment and income generation in the state economy. The strengthening of IEMA will provide this management agency with more appropriate conditions for exercising its functions, to promote sustainable development. Implantation of the Environmental Management System Accompanying the above mentioned institutional strengthening, the implantation of an environmental management system is planned, allowing for the preservation and recuperation of river and sea water quality. These actions in the Greater Vit6ria water and sewer systems will lead to important improvements in the quality of life of the population and a substantial reduction of Executive Summary 12 DATES FOR THE WORKS HORIZONS OF GREAT VITORIA SANITATION SYSTEM pollution in water bodies. The population that will be benefited with the improvement efforts in water supply is expected to be about 1,330,000, while the population attended by sewage treatment will grow by more than 350,000. In addition to the PRODESAN sanitation works utilizing installed capacity, there are some works to expand coverage. In this category, there are four interventions that are already being discussed with environmental agencies, which will bring notable improvements in the water quality of local beaches. The Manguinhos and Nova Almeida systems were well defined in the Master Plan for Sanitation for the municipality of Serra. The location of the sanitation plant is close to the urban area, in a pasture area without human occupation or apparent environmental restrictions with respect to public works. The Viana and Guarapari Systems resulted from preliminary studies and should require additional efforts. The Jucutuquara system is a result of a study during the PRODESPOL period. It includes coverage expansion works for Vit6ria, with the implantion of a collection networks and pumping stations, taking sewage to the Mulemba treatment plant.

Despite high levels of urban occupation, these basins still have 10% of their areas covered by natural forest reserves and approximately 15% of their areas used by agriculture. The environmental system includes 25 Protection Areas in these basins. The Jucu and Santa Maria da Vitoria rivers provide the entirety of water supply for Greater Vitoria, a region that includes about 50% of the state population, as well as the most important industrial and commercial complex. 1.5.1 Attending Environmental Policies With respect to environmental policies, the new projects and the improvement of existing projects can be thus characterized: 1.5.1.1. Environmental Assessment (OP 4.01) The new sanitation and water supply systems will follow the same procedures adopted by other undertakings financed by the World Bank already in operation. For this end, the projects are concerned with fostering the involvement through prior consultations of the environmental management agency (SEAMA/IEMA), starting with the design phase and selection of location alternatives and continuing through installation and operation phases. 1.5.1.2 Natural Habitats (OP 4.04) The Aguas Limpas Program is located in the Vit6ria Metropolitan Region. There are no habitations in the new sanitation systems areas, normally pasture areas. Improvements in sewer systems (network expansion) will involve public works in the urban area. Executive Summary 1 5 Espfnto Santo Water and Coastal Pollution Management Project: Aguas Limpas Project Similarly, the new water supply projects are located in the basins where already implanted projected operate, in non occupied areas, with no social or environmental impacts detected. 1.5.1.3 Resettlement (OP 4.12) For all sewage projects, the following considerations apply: i) Sewage networks/ouffalls/transmission mains The entire sewer networks will be located on public lands, with no interferences in private properties, eliminating concerns about dislocation or resettlement of residents or of removal of land improvements. li). Pumping Stations The selected areas for locating the pumping stations are situated on public lands (parks, public gardens, municipal lands) or private lands that are currently unoccupied and uninhabited. iii) Sewage Treatment Systems All the location alternatives considered for treatment units are in non occupied areas so that there will be no need to resettle residents or remove land improvements. The water supply projects include expected improvements plants that have existed for more than 20 years, in areas owned by CESAN, so that there will be no need to resettle residents or remove land benefits. With respect to pipelines and reservoirs placed in public areas, these will also involve no interferences in private properties, eliminating concerns about dislocation or resettlement of residents or removing land improvements. 1.5.1.4 Cultural Property (OPN 11.03) With respect to the existing sewer and water systems that will be improved, these were subjected to environmental studies, are licensed and in operation. With respect to the areas where new sewer and water supply systems will be implanted, there is no indication that these are located on archeological sites or areas of cultural or historical importance. Executive Summary 16 Espirito Santo Water and Coastal Pollution Management Project: Aguas Limpas Project 1.6 Environmental Evaluation of the PRODESAN and Aguas Limpas Project Water quality monitoring on Vit6ria's beaches has been conducted at 23 places since 1986, without interruption. In the other Greater Vit6ria regions, monitoring was initiated in 2002. W > i $=. s z The recent initiation of operation of four Kd - sewage treatment plants in Greater Vit6ria and another in Domingos Martins wvIrclRL - ,i i-9 ihas not yet had measurable impacts. The 'T0 VllORIA ,09^,J¢#t l F----short time that these plants have been operating does not allow for temporal correlations of the water quality of *- -. ;¢- . ;L;- receiving bodies of water. However, it is possible to affirm that the receiving bodies receive today a smaller pollution - , t:" l > load, thus initiating a cycle of de-pollution of the region's river waters, of the Vit6ria P j bays and adjacent coastline. In a few Localizac,o dos pontos de monitoramento months, it will be possible to measure the impacts of the PRODESAN projects in the levels of bathing water quality standards (balneabilidade) of the region. For a more detailed analysis of water quality for the Jucu and Santa Maria rivers, Vit6ria bay and the coastal region, a hydrodynamic model will be implanted, permitting simulation of contaminant transportation in Greater Victoria's water bodies, including in the municipalities of Baia de Vit6ria, Gurarapari, Manguinhos and Nova Almeida. The model will simulate in an integrated fashion the river, estuary and coastal areas of the regions of interest. With this, it will be possible to characterize through simulations, the environmental situation before and after PRODESAN and the Aguas Limpas Project. It will also be Executive Summary 17 Esptfto Santo Water and Coastal Pollution Management Project: Aguas Limpas Project possible to simulate the analysis of alternatives for the release of treated sewage for new sewage plants in the greater Vit6ria region. The Aguas Limpas Project intends to contribute to IEMA's and CESAN's management and technical capacity, principally with respect to water resources and environmental management. To do so, an institutional strengthening program was designed (Item 1.7), as well as an environmental management plan (1.8), which was later perfected in meetings with World Bank consultants. The environmental evaluation of each new project will have an environmental monitoring (specific subproject), as detailed in section 8 (§ 8.2). All the works need a detailed environmental evaluation before their implementation. These environmental evaluations have to be previously approved by the World Bank. Thus, the following two sections (1.7 and 1.8) are interrelated, seeking to expand state actions in the environmental and water resources arenas, as a continuation of government efforts to recuperate the environmental quality of the state. 1.7 Institutional Strengthening of IEMA and CESAN The Institutional Strengthening Program is about the development of structural subprojects that are internal to each of the two agencies and involves the following Subprojects.

The Integrated System of Environmental Information sub-project has this end. In the collection of environmental and water resources data, it will be necessary to redimension and complement the existing qualitative and quantitative monitoring network in the Espirito Santo river basins. This issue is addressed in the Environmental and Water Resources Monitoring Network sub-project. The improvements in Environmental Licensing sub-project will incorporate one of the most important command and control instruments of the environmental system, improving registers of potentially polluting activities, establishing criteria to expand municipal environmental licensing and other measures that will allow for the modernization of the sector. With respect to water resources management, there will be a specific sub-project that will help the state in, among other activities: the consolidation of a registry of water users based on secondary information, the implementation of a system of concession of water use rights, the implementation of criteria for charging for bulk water use rights, and in the development of criteria for the adaptation of environmental classifications to water rights criteria. There will also be efforts to build environmental and water resources capacity. The sub-projected dedicated to strengthening the environmental capacity of CESAN includes specifically the tasks of (i) water source management in the metropolitan region; (ii) sewage treatment plant residue management; and (iii) the implantation of ISO-14000 in two sewage treatment plants. In this sense, CESAN has taken on two commitments with the World Bank: Executive Summary 19 Esplrito Santo Water and Coastal Pollution Management Project: Aguas Limpas Project i) Commitment with respect to sewage treatment plant residues: CESAN, as part of the conditioning factors for environmental permits for the operation of sewage treatment plants (Mulemba, Bandeirantes, Arac,s and Praia do Morro) will, before initiating the physical interventions of the Aguas Limpas Project, approve together with IEMA the treatment and final destination of the sludge produced by the respective plants. ii) Commitment with respect to SGA-ISO-14000: CESAN is commited to concluding the implementation of the SGA in the two pilot units (Carapina water treatment plant and Bandeirantes sewage treatment plant) with ISO certification within two years after beginning the contract activities. 1.8 Environmental Management Plan The second section, "Environmental Management Plan" deals with sub-projects where both of the agencies (together with the UGP and other agencies) work in an integrated and cooperative fashion. The Environmental Management Plan was conceived as a complement to the activities mentioned in the last section. It deals with sub-projects where both CESAN and IEMA, together with the UGP and other agencies, work in an integrated and cooperative fashion. The intention is to create an Environmental Management System that will work through various agencies, CESAN and IEMA among them, performing a central role. This system has nine sub-projects, as the illustrative chart below shows.

An engineering consulting firm will be hired by the UGP to finalize designs for works, produce bidding documents and supervise construction from a technical and environmental standpoint. 1.8.2 Social Communication Program The Social Communication Program will involve principally actions related to the coexistence of the population with the works to be carried out. The objective is to inform the target community about each stage of construction so as to minimize the disruptions caused by the physical interventions of the Program. We hope that the target community will give greater support to the construction process in the locale and to the conservation of the basic sanitation systems implanted. This is related to section 1.8.9 on the Environmental Construction Manual. 1.8.3 Sanitary and Environmental Education Program The program intends to carry out educational activities on sanitation and environment with organized civil society, NGOs and students in the area affected by the Aguas Executive Summary 21 Espfrto Santo Water and Coastal Pollution Management Project: Aguas Limpas Project Limpas Project. It intends to increase consciousness with respect to the importance of environmental sanitation and rational water use for improving quality of life. 1.8.4. Program to Promote Connecting to the Sewer System The Program to Promote Connecting to the Sewer System intends to develop informative and educational activities, to promote perceptions of the importance of treated water and the adequate disposal of domestic sewage. These actions will also demonstrate the importance of connecting to the system, providing guidance on the correct way and deadlines for doing so. On this occasion, clients will receive communication on the financial costs of maintain the services that will be provided. 1.8.5 Program to Eliminate Crossed Connections This sub-project has the following two objectives: (i) the identification, registration and transference to the sewage networks of lines connected to the storm drainage system; and (ii) the identification, registration and elimination of rain water running into the sewage collection network. 1.8.6 Sewage Master Plan for the Vit6ria Metropolitan Region The last Sewage Master Plan for the Vit6ria Metropolitan Region (1978) is now out of date, obliging CESAN and IEMA to confront demand increases without adequate planning. Thus, in the same manner that the Bank promoted the updating of the Sewage Master Plan for the Serra Region, in 1998, a sub-project will update the plan for Greater Vitoria. 1.8.7 Hydrodynamic Modeling Program This section presents a summary of the minimum requirements for a computational modeling system to be used in the context of Aguas Limpas Project. The system is intended for environmental simulations of hydrodynamic circulation, water quality, and transport of contaminants in water bodies. The following minimum requirements must be present in the modeling system: Integrated simulation of rivers, estuaries and coastal waters: Executive Summary 22 Espfrto Santo Water and Coastal Pollution Management Project: Aguas Limpas Project The modeling system must be capable of simulate rivers, estuaries, bays and coastal waters within the same modeling domain. Sub-models transferring data one to the other are not acceptable. Dealing with regions with complex geometries: Due to the previous requirement, it is desirable that the modeling strategy be based on discretizing techniques capable of mapping domains with complex geometries. For that, it is recommended that the models use finite elements, or curvilinear grids for horizontal discretization, and D coordinates for the vertical direction. Similar techniques may be accepted. "Finite Differences" models, with retangular grids will only be accepted if they facilitate automatic alignment and are capable of fulfilling item 1 above. Minimum set of models in the system The system must contain at least the following models: Hydrodynamic Model: it can be a constant density 3D/2DH hydrodynamic circulation model. The model must accept inputs of variable discharges in points, cross section of rivers or distributed along shorelines. Must also comply with variable wind fields in time and space, variable tidal conditions along open boundaries, prescription of coastal currents, and consider the possibility of variable bottom stress in time and space. The Water Quality Models: a set of dedicated Eulerian transport models for the coupled simulation of water quality parameters like generic contaminants, salt, temperature, DO-BOD, nitrogen compounds, and biomass. Simulations can be applied for 2DH flows or for selected layers of 3D flows with a given thickness. Lagrangian Transport Model, deterministic mode: a general purpose advective diffusive transport model with kinetic reactions for selected layers of 3D and for 2DH flows. This model is especially suitable for simulation of plumes of ocean ouffalls or clouds that are initially small to be well resolved by the discretizing mesh of the associated hydrodynamic model. These are usual situations in modeling plumes of outfalls and oil spills. Executive Summary 23 Espfdto Santo Water and Coastal Pollution Management Project: Aguas Limpas Project The Lagrangian Transport Model, probabilistic mode: the user can produce maps of isolines of probabilities base on N events or for a period of time T. Examples of required results are isolines of probability of visitation of a plume/cloud with concentrations above a given limit; ditto with lifetime below a given value; determination of critical events, e.g., the first event or first time in which a plume or cloud touches the coastline, etc. The interfaces should be user friendly in a Windows XP environment, permitting the flow of data among system parts and generating tables with reports, maps and graphics. 1.8.8. Plan for Alternatives for Treatment and Final Disposal of Sewage Treatment Sludge CESAN shall elaborate a plan for Sewage Treatment Sludge and submit it to IEMA before implementation, in order to satisfy the environmental conditions included in the recently installed Operation Permits of Sewage Treatment Plants. In the context of the Aguas Limpas Project, CESAN has made a commitment to the World Bank to finalize the Plan for Alternatives for Treatment and Final Disposal of Sewage Treatment Sludge with its own funds. The agreement is that the beginning of the physical interventions of the Aguas Limpas Project depends on CESAN fullfilling this commitment, described in section 7.8.1 of chapter 7 of the main report. 1.8.9. Environmental Construction Manual Many of the impacts promoted by the infrastructure is inherent to the construction phase. Among other impacts, it is worth citing: (i) increase in noise and dust levels and motor gas emissions; (ii) temporary closure of roads, sidewalks and building access; (iii) traffic detours; (iv) the circulation of strangers in neighborhoods; (v) heavy vehicle traffic; (vi) harm to public equipment; (vii) treatment and final disposal of solid and liquid residues, etc. These impacts can be minimized through adequate construction criteria and methods, which the state government will include in the construction bidding regulations as requirements for the execution of contracted services. Executive Summary 24 Espftto Santo Water and Coastal Pollution Management Project: Aguas Limpas Project 1.9 Public Consultation. The state government promoted two events to present and discuss the Aguas Limpas Project, with widespread dissemination in the local media (radios, newspapers and television). The most discussed and prioritized themes were: (i) Treatment and final disposal of the sludge produced in the Sewage Treatment Plants; (ii) Population support for the sewer system; and (iii) Elimination of crossed connections. All these issues are discussed in Chapters 7 and 8 of the main report.
