Gestão dos serviços públicos de água e esgoto operados por municípios em Goiás, GO, Brasil
(2016-06) Arruda, Poliana Nascimento; Lima, Aline Souza Carvalho; Scalize, Paulo Sérgio
The characteristics of services provided and the regulations governing their cost both
contribute to the satisfaction of the consumer. Therefore, the aim of the study was to analyze
the quality of public water and sewage services in 21 municipalities of Goiás, to include
billing procedures and consumer satisfaction, and taking into account whether or not the
operations were regulated. To accomplish this, we conducted on-site visits to complete
questionnaires relating to our interviews with managers to obtain technical information and
with consumers to determine their level of satisfaction. It was observed that systems are managed by local authorities in ten municipalities, four by city hall departments or appointed
officials, and seven did not have any specific regulatory oversight. Seven municipalities had
no water treatment; of those, six had no specific regulatory oversight, revealing the lack of a
planned management system. In 57.1% of the municipalities, there was no sewage treatment
and sewage was dumped in soak pits. These had no governing body, and the price-charging
adjustments were established in three ways: i) approval of the project by the Town Hall
councilors; ii) decree by the mayor; and iii) analysis by the Municipal Sanitation Council
(CMS). The satisfaction of the consumers was related to economic, cultural and, especially,
political factors, and the existence of a management system improved infrastructure
conditions.
Avaliação de métodos para determinação de cloro residual livre em águas de abastecimento público
(2016-06) Soares, Samara Silva; Arruda, Poliana Nascimento; Lobón, Germán Sanz; Scalize, Paulo Sérgio
To assurance the drinking water quality, the disinfecting has to be guaranteed. In this sense, chlorination is the most widely used method, which promotes the inactivation and/or destruction of pathogenic microorganisms. The analytic methods more common for free available chlorine in drinking water are based on the DPD colorimetric method. In this way, the main core of this research is to compare the results obtained between two devices that can use two types reagents: visual and digital equipments; and powder and tablet reagents. Moreover, was analyzed whatever correlation between the others measured parameters: pH, turbidity, electric conductivity, fluoride, total coliforms and Escherichia coli. Were collected 40 samples in particular homes, which were distributed in six districts of three different areas of the city of Goiânia (Goiás, Brazil). The results were that the powder reagent had higher values than tablet ones, and that the measures of the digital equipment were lower than the visual disk. By other hand, was found one linear correlation between turbidity and the free available chlorine, and one soft inverse relationship between the fluorine and the electric conductivity.
Satisfação e percepção dos usuários dos sistemas de saneamento de municípios goianos operados pelas prefeituras
(2017-06) Lima, Aline Souza Carvalho; Scalize, Paulo Sérgio; Arruda, Poliana Nascimento; Baumann, Luis Rodrigo Fernandes
Meet consumer satisfaction as sanitation services is a tool to assist
in their management. This study evaluated consumer satisfaction
regarding the sanitation services directly managed by local governments
of 21 municipalities in the state of Goiás. In the evaluation of satisfaction
with the characteristics of all sanitation components, we used the interval
scale. We verified the perception of consumers in relation to the reality
of sanitation by comparing the results in the forms with the conditions
observed in visits to municipal agencies responsible for sanitation.
To that, 479 forms were applied with the people selected at random, and
the number of forms used in each city was obtained using the Neyman
allocation rule. It was found that satisfaction prevails for water supply,
collection and transportation of waste. However, dissatisfaction prevails
for urban drainage, waste disposal and all indicators relating to sewage.
Small portion of the population is expressed as indifferent, showing
consumer preference in positioning. It was observed that the perception
of consumers was consistent with the reality of the municipalities
perceived during the visits.
