Sewer networks - Hydroplan
Being the veins of the urban wastewater cycle, sewer networks perform a vital task in society. Sewers are invisible but nonetheless represent an enormous capital.
Due to their invisibility and relatively long expected lifetime, sewer systems often donít get the attention they deserve, with all related consequences. Sewer collapses and flooding can have serious financial, socio-economic and environmental impacts. To prevent this there are several preventive measures available like cleaning, inspection and rehabilitation of sewers.
Aquafin has developed a risk-based engineering methodology, Hydroplan, which allows for asset managers to integrate risk assessment in their asset management practices in order to increase cost-effectiveness and decrease nuisance for the customers. Hydroplan searches a balance between investments in preventive and curative actions and will in time reduce the financial impact.
