Abstract(s)
Nos dias de hoje, as atividades relacionadas com o abastecimento de água e
saneamento, encontram-se em processo de desenvolvimento exponencial, existindo uma
profunda mudança de paradigma, no sentido da qualidade, dos processos e do produto
bem como a observação de medidas ambientais cada vez mais rigorosas.
Dadas as constantes exigências a que se assiste atualmente, o consequente aumento
do investimento necessário, é essencial diminuir os gastos inerentes a esta atividade,
tornando-a cada vez mais eficiente, fornecendo o melhor produto ao mais baixo preço. Por
outro lado, a vertente social inerente ao abastecimento da água torna necessária uma
fatura mais baixa o que condiciona uma vez mais a necessidade de diminuir os
desperdícios, otimizando a relação gasto/lucro. Uma das áreas essenciais à eficiência é a
manutenção dos sistemas, com vista a manter ao máximo o seu tempo de vida útil,
diminuindo assim os gastos com equipamentos e infraestrutura.
As metodologias de eliminação de desperdício (Lean) ao longo de uma cadeia
produtiva vêm sendo cada vez mais adotadas como meio para aumento da qualidade do
produto. Sendo uma metodologia cada vez mais explorada, e tendo como base um
conceito de melhoria contínua, o Lean é uma ferramenta que tem vindo a sofrer alterações
no seu sentido de paradigma, transferindo a visão tradicional de aplicação aos sistemas de
produção para uma implementação nas atividades de serviços.
Assim, a implementação de uma metodologia Lean que seja particularmente sensível
à atividade de manutenção na área de serviços de abastecimento de água e saneamento
de águas residuais, pode constituir-se como uma tarefa inovadora e ao mesmo tempo
complexa, no sentido de evidenciar novas formas de manter esta atividade com o mesmo
nível de qualidade e quantidade a um custo inferior.
No caso particular da implementação da manutenção Lean numa Estação de
Tratamento de Águas, a inclusão de ferramentas tais como a Manutenção Autónoma, a
Engenharia de Manutenção, o TPM, o mapeamento da cadeia de valor pode permitir uma
diminuição dos custos associados de valores superiores a 80% no caso da manutenção
corretiva e 50% no caso da manutenção preventiva.
Nowadays, water supply and waste waters related activities are yet in an exponential development process, where exists a deep changing philosophy, looking towards quality, processes and products, never disregarding the increasingly strict environmental care. Due to constant actual demands and the consequent and needed investment increase, the reduction of related costs becomes essential in this activity, therefore also becoming more efficient, allowing a product delivery at the most lower price. On the other hand, the social aspect related to water supply also needs to lower the consumer bill, which walks side by side with the need to decrease production waste, in a cost/profit based relation. One of the essential areas on efficiency processes is system maintenance, aiming to maximize life time on all equipment’s and all infrastructures, directly resulting on lower costs. Product waste elimination methodology (Lean) all the way in to a productive chain is becoming to be more and more selected as mean to product quality increase. As an increasingly explored methodology, based on continuous improvements, Lean is a constant changing toll in its own philosophy, transferring the traditional view on productions system application to be implemented on service activities. Thus, Lean methodology implementation sensitive to services of water supply and waste water treatment maintenance area, may become, at same time, in to an innovating and complex task, as long as it seeks to highlight new ways to sustain this activity with same level quality and quantity at a lower cost. In this particular case of LEAN maintenance implementation in an Water Plant Treatment, adding tools as Self Sustained Maintenance, Maintenance Engineering, the TPM and the chain value mapping, may allow an association of cost reduction above 80% on corrective maintenance and 50% on the preventive maintenance
