| dc.description.abstract1 | Paranoá Lake is an urban lake and it is being used as a source for urban water supply
since last year. Until 1990, algal blooms occurred and improvements on wastewater treatment plants
carried out improved the water quality very rapidly due to phosphorus load reduction. Recently,
water quality is deteriorating, which is probably due to diffuse pollution. In Brazil, we adopt
separated pipe networks for sewage and stormwaters, although cross flows occur. The evaluation
of urban drainage stormwaters entering the lake and proposition of technical alternatives is crucial
in minimizing the impacts on lake water quality. Quantitative and qualitative behavior of urban
stormwaters were analyzed by means of monitoring the runoff flows and pollutant concentrations.
Mathematical modelling while using the Storm Water Management Model—SWMM was carried out,
and good correlations were found for flow modelling. However, poor response was achieved for
water quality simulations, affecting the simulated pollutant loads entering the lake. The simulation of
13 alternatives for detention ponds location was also evaluated, as well as their influences on flow
damping capability. The detention ponds that were tested were placed in line in the drainage mains
to study the effects of their location on the removal of pollutants. As expected, the results showed
that ponds located near the outfall are more efficient in reducing flow peaks. However, this layout
requires construction woks in areas that are more sensitive to environmental and urbanistic problems
and with higher land commercial values. Alternatives with smaller volumes in public areas near the
center of the catchment area can lead to the peak flow damping required by the existing drainage
network to avoid overflows. In conclusion, detention ponds can be a good alternative for improving
the stormwater quantity and quality, but also alternatives that promote increased infiltration, should
also be considered for compensating the infiltration lost due to urbanization. | pt_BR |
