Taxing for stormwater drainage systems.
This article evaluates the possibility of creating a tax for urban drainage in order to make the system self-financing. Average costs of implementation and maintenance of the services were used to individualize the charges and definition of the tax. The conventional drainage system was evaluated along with a source control alternative, water detention in tanks on the lot. The magnitude of the values being charged varies in function of the impermeable surface and the density of the urban area. Preserving creeks in natural conditions and using source control approach, are all options with the advantages of lower investment and smaller burden for the users.
