"Many semi-urbanized lakeside villages are facing the problem of surface water quality deterioration owing to uncontrolled discharge of stormwater or the interaction of onsite wastewater disposal systems with the surface water. Traditional stormwater BMPS (Best Management Practices) such as large-scale detention ponds may not be feasible solutions for these villages, due to their small size and limited resources. The current study investigates the potential of lot-level stormwater BMPs for land-restricted lakeside villages. Rear yard ponding, wherein roof runoff is removed by evaporation and infiltration, is being investigated in a lakeside village in Portland, Ontario. HEC-HMS is used to estimate the optimum baseline storage of stormwater for the existing drainage basin. The quantitative effectiveness of rear yard ponding can be obtained by comparing the integrated onsite storage provided by all applicable lots in the village to the baseline storage. The movement of phosphorus is also being monitored at a typical lot to investigate the potential of enhanced flushing of subsurface wastewater effluent by ponded stormwater"--Abstract.
