Viability of creating a water agency in the Grande river basin, Bahia

The work was developed from the analysis of the viability of creating a water agency in the Grande river basin, located in western Bahia, Brazil. The charging mechanisms of five different water agencies in Brazil were applied to the basin. The simulations showed the possibility of an average annual collection in the basin of over R$ 2.2 million, which would provide a median value above R$ 160,000 per year for administrative costs of the agency. Thus, considering that the median value of the annual administrative cost to state agencies is close to R$ 300,000, the collection provided by the mechanisms studied would not initially allow the creation of a water agency for the Grande river basin. However, the adoption of one of the existing water agencies would be a more appropriate alternative for the implementation during a shorter period of time, given the technical and operational structure within which the current agencies function.


INTRODUCTION
The water agencies are part of the National System of Water Resources Management (SINGREH), being its creation authorized by the competent water resources council, upon request of the river basin committee, once its financial viability is ensured by charging for the use of water resources (BRASIL, 1997). Working as the Executive Secretariat of the Watershed Committee (CBH), the agencies carry out technical, financial and administrative functions, as well as the joint development within a model of shared management of water resources .
The Brazilian experience shows that the country has private entities created or selected to be Water Agency, such as the Paraíba do Sul River Basin Water Management Association (AGEVAP), the PCJ Agency Foundation, the Executive Association of Support for the Management of Hydrographic Basins Peixe Vivo (AGB PEIXE VIVO), the BioAtlantic Institute (IBIO-AGB Doce), the Foundation of the Alto Tietê River Basin (FABHAT), the Araguari River Basin Agency (ABHA) and the Vale do Itajaí Water Agency Foundation .
There are also various public bodies eventually in water agency functions, such as the National Water Agency (ANA), the Department of Water and Power of the State of São Paulo (DAEE) and the Water Resources Management Company of the State of Ceará (COGERH). In ANA (2014, p. 26), […] this model of public bodies with agency function, has made possible the necessary basis for the implementation of committee-agency systems, decentralized and supported by funds raised by charging for the water use.
The imposition of water agencies and charging for the use of water resources takes on greater importance in areas where there is intensive use of water, as occurs in the Grande river basin, located in the west of the state of Bahia. Thus, the object of the present study was to analyze the feasibility of creating a water agency in the Grande river basin in order to provide subsidies for the discussion and the creation of an agency for the basin.

Study area
The Grande river basin ( Figure 1) shows an area approximately 78,500 km 2 , corresponding to 13.9% of the area of the state of Bahia (ALMEIDA; MOREIRA; SILVA, 2014). The Grande river produces the third largest water source flowing into the São Francisco river basin (PEREIRA et al., 2007); however, there are conflicts over the use of water, which demand an adequate management of its water resources (ALMEIDA; MOREIRA, 2013).
The Grande River Basin Committee (CBH-Grande), created by Decree nº. 11,246, October 17 2008, includes 17 municipalities in the western part of the state of Bahia. In 2015 the CBH-Grande approved the creation of the Technical Chamber of Granting and Collection and is developing its plan of water resources, important steps for the establishment of charging for the use of water resources in the basin.

Survey of data on the granting of rights to use water resources
Considering that the use of water resources subject to the granting of rights of use of water resources will be charged and considering that the Grande river basin only has rivers within the state domain, the data regarding the granting of the basin were obtained with the Direction of Regulation (DIREG), of the Institute for the Environment and Water Resources (INEMA), once INEMA is the managing body of water resources of the state of Bahia. The data were made available by physical means (Official DIREG no. 02764/2015) and in digital format.
The information provided includes the number of the process, the type of impound, the purpose of the use, the municipality of the grant, the location coordinates, the number of the ordinance, the date of publication in the Official Gazette of the State of Bahia (DOE-BA), the flow granted and the type of release of use (concession, authorization or dispensation). A preliminary treatment was performed in the data that consisted of the pre-processing of the grants and the consistency analysis.
The pre-processing comprised the analysis of the database provided by DIREG, which corresponded to the grants issued by INEMA until September 2015. The concession of water resources in the state of Bahia is granted in cases of public utility, and authorization is granted in other cases. Considering that the concession of a grant may have the maximum period of validity of 30 years, while the authorization is of a maximum of four years (BAHIA, 2007), an analysis was carried of the grants whose concessionary orders were issued from September 1985 and authorization as of September 2011, were issued. The grants of other years were discarded.
The consistency analysis for the current grants was made through the identification of possible failures, such as the existence of extreme or null values. In the case of inconsistency, the values were updated based on the DOE-BA's concession granting research.

Analysis of the viability of creating a Water Agency in the Grande river basin
In order to analyze the feasibility of creating a water agency in the Grande river basin, the amounts charged for the use of water resources were evaluated, including the maintenance costs of an agency, and the legal requirements for charging in the Grande river basin.
The amounts that can be charged were calculated considering current concessions in the basin as of September 2015 and the parameters and equations obtained in CEIVAP (2014) Based on data for charging, the resources collected and the maintenance cost of each of the respective agencies, the percentage representation of the administrative cost of the agencies in relation to the resources collected from the charging of water resources was calculated.
The representativeness of the administrative costing of water agencies was analyzed, based on the limit for resource use established in art. 22 § 1 of Law nº. 9,433/1997 (7.5% of the collection), the resources that could be made available for the administrative cost of an agency in the Grande river basin were calculated.
An analysis of the resources available for administrative costs of a water agency in the Grande river basin was carried out, compared to the average cost of the basin agencies under study. It was analyzed whether the proceeds from the collection in the basin would be sufficient to bear the costs of setting up an agency or adopting a pre-existing agency.
Considering that the institution of charging and a water agency, in addition to financial matters, demands the fulfillment of legal requirements, the perspective of the institution of the charging for the use of water resources in the Grande river basin were evaluated, considering the existence of the water resources plan and the creation of technical commissions to study and implement the charging.
Considering that the Grande river is state-owned domain, the legal requirements for the institution of charging under the Thus, the creation of the river basin committee, the drafting of the basin water resources plan by the river basin committee, and the approval of the basin plan by the competent Water Resources Board are requirements for the institution of charging (BRASIL, 1997;BAHIA, 2005BAHIA, , 2009).

RESULTS AND DISCUSSION
The values charged and collected, the administrative costs and the representativeness of the administrative costs of the Association for the Management of Waters of the Paraíba do Sul River Basin (AGEVAP), the PCJ Agency Foundation, the Executive Association for the Management of the Hydrographic Basin Peixe Vivo (AGB PEIXE VIVO), the BioAtlantic Institute (IBIO-AGB DOCE) and the Alto Tietê River Basin Agency Foundation (FABHAT), for the year 2015, are presented in Table 1. In the charging of resources, the effective transfer of the managing body to the agencies, the income from financial investments and the balance of the previous year were considered.
Considering the values presented in Table 1, it is important to note that AGEVAP was created in 2002 to be the executive The same situation happened with AGB PEIXE VIVO, which was created in 2006 to act as a water agency for the Velhas River Basin Committee (CBH-VELHAS), subsequently incorporating another tributary of the São Francisco river, CBH-PARÁ and, finally, the CBHSF.
The figures presented in Table 1 show a federal average collection of over R$ 49 million and administrative expenses of the agencies of two million, representing 4.8% of the water use charging. At a state level, the results show an average collection above 16 million and an average administrative cost of 570 thousand, representing 4.5% of the charging resources. In general, considering federal and state river basin agencies, there is an average collection of 33 million and administrative costs of 1.3 million, which represents 4.7% of the resources collected from the water use charging.
In view of the extreme amounts of charging and collection shown in Table 1, where there is a federal collection of R$ 80 million, and the other R$ 20 million, the median allowed to represent the reality of the distribution of values. As a result, the average administrative costing of the agencies was R$ 1,917,465.56 (Federal), R$ 316,048.59 (State) and R$ 1,263,161.41 (federal and state agencies).
It is important to note that Peixe Vivo Agency/CBHSF, among the federal basins, presented the highest administrative cost. This factor can be justified by its higher collection and, mainly, by the coverage of the São Francisco river basin.
At the state level, the CBH-MPS and CBH-Piabanha stand out because they have the lowest administrative costs, which can be explained by the fact that these committees have formalized a management contract with AGEVAP, taking advantage of the existing administrative, technical and operational capacity of the agency.
It should be noted that it is common for a single water agency to manage the resources of more than one basin, such as AGEVAP, which works with CEIVAP and four affluent committees to the Paraíba do Sul river (CBH Médio Paraíba do Sul, Commitee Piabanha, CBH Rio Dois Rios and CBH Baixo Paraíba do Sul and Itabapoana), including the Peixe Vivo Agency, which represents CBHSF, CBH-VELHAS, CBH-PARÁ and CBH-VERDE GRANDE.

The amounts collected from the charging for the use of water resources must be used for, in addition to the financing of projects and works included in the water resources plan of the basin, the payment of implementation expenses and administrative costs of the organs and entities that are members of SINGREH, including the water agencies, but limited to 7.5% of the total collected (BRASIL, 1997).
Even the values of administrative costs between the basins taken as example being quite distinct, the data provides a reference for the analysis of the feasibility of implementing a water agency in the studied basin.
It is important to emphasize that the basins used as reference are in regions where there is a greater diversification of the water uses among users, which differs from the reality of the Grande river basin, where there is the predominant use of irrigated agriculture. Table 2 presents the resources that can be charging considering different mechanisms and the maximum administrative cost that could be used to pay implementation expenses and administrative costs for the creation of a water agency to provide administrative, technical and financial support to the Grande River Basin Committee (CBH-Grande).
The simulation presented in Table 2 shows an average collection of more than R$ 2.2 million, which would make resources available in the average of R$ 170,000 for administrative costs of the agency. The mechanism of the state of São Paulo was disregarded in the analysis, in view of the extreme values generated and their inapplicability to the reality of the Grande river basin, due to the lack of a specific coefficient for agriculture.
Considering that the average administrative cost of state agencies is close to R$ 600 thousand (Table 1), the collection provided by the mechanisms studied does not initially make it possible to create a water agency for the Grande river basin, considering the generation of resources for administrative costings in the order of R$ 170 thousand, on average, not reaching this level, in addition to the costs to implement the infrastructure necessary for the proper functioning and maintenance of qualified technical staff.
The simulated value of charging by the CBHSF mechanism was different from the CEIVAP and PCJ mechanisms, but similar to the CBH-DOCE. The factor that justified the difference in the calculated amounts was the coefficient for irrigation, animal husbandry and aquaculture (Kt), whose value of 0.025 lowers substantially the collection by the CBHSF and, consequently, the available value for administrative costings.
Considering this aspect, the mechanism used in the São Francisco river, of which the Grande river is its affluent, is what gives less collection potential. Therefore, the Grande river basin committee should consider the implications of adopting such a mechanism.
The resources for administrative costing derived from the simulation of charging by the CEIVAP mechanism, and mainly by the PCJ, reach levels similar to the median cost of the state agencies and may enable the creation of a water agency to exercise the function of executive secretariat of CBH-Grande, or the adoption of one of the existing agencies, which is an easier alternative to be implemented in a shorter time, given the pre-existence of technical and operational structure of functioning.
In the case of the option to create the water agency, the authorizations by the Water Resources Board and the institution of the charging are required to guarantee the financial viability for the maintenance of the agency (BAHIA, 2009;BRASIL, 1997). The Grande river basin has an operation committee, but has not yet implemented the charge for the use of water resources.
In order to implement the charging, approvals of the Water Resources Plan by the Grande River Hydrographic Basin Committee (CBH-Grande) and the Bahia State Water Resources Council (CONERH) are required. In Bahia, CBH-Grande has one of the most advanced processes for the charging institution, since this committee is finalizing its Water Resources Plan (CBHSF, 2015). In addition, another important stage for the charging was implemented, with the creation of a Technical Chamber of Granting and Charging by the basin committee in the second half of 2015 (BAHIA, 2015).
The institution of the charging in the Grande river basin can provide benefits to the users of water of the basin due to the better management of the water resources and the accomplishment of projects that promote the environmental recovery. On the other hand, the collection is still poorly seen by the water user segments, which would require better disclosure of their objectives so that it can fulfill its role as a rational water use and to obtain financial resources to finance the programs and interventions included in the water resources plans.
It is important to note that the simulated charging values may have been underestimated due to the possibility of users in the basin using water without the respective grant. As an updated and representative grant database affects charging calculations, the charging mechanisms used may not have been sensitive to the actual use of the water in the basin. Therefore, in order to implement the charging, campaigns are needed to register users of water resources in the basin.
In Moreira et al. (2012, p. 12), it is necessary a […] greater control over the uses of water without the respective legal instrument, since the abstraction of water without its authorization compromises the actions of the managing body with regard to the quantitative and qualitative control of the water in a basin, as well as to charging for the use of water. Viability of creating a water agency in the Grande river basin, Bahia 6/7 Regarding the applicability of the mechanisms used in the study, it is worth highlighting the fact that they were developed and are being adopted in regions with significant differences in relation to the conditions of the Grande river basin, in which there is the intense use of water by the agricultural sector. Thus, in order to carry out the charging, it is necessary, within the framework of CBH-Grande, to discuss a mechanism appropriate to the conditions of the basin.
In addition, for the creation of a water agency, it is necessary to consider the impacts that the financial noncompliance by the user segments could generate in the maintenance of the agency. Although the historical data of the charging in the country shows that the value of the collection is close to the amount charged, representing 96.2% (ANA, 2015), in case of higher noncompliance can compromise the functioning of the water agency.
Thus, considering the amounts that can be charged and estimated values for administrative costing, it is verified that the financial viability for the adoption of an existing agency can be assured by the institution of the charging for the use of water resources in the Grande river basin.

CONCLUSION
From the analysis of the results, it can be concluded that the collection provided by the charging mechanisms for the use of water resources studied does not initially make it possible to create a water agency for the Grande river basin. However, it would allow the adoption of one of the existing water agencies, given the pre-existence of technical and operational structure of functioning.
