The Southdown Grid LID project will assess the technical and financial feasibility of implementing communal, integrated water management systems on private property. This will involve aggregating properties together to share communal systems designed to achieve stormwater management and water conservation objectives, and to realize reductions in infiltration and inflow (i.e. stormwater ingress) to the sanitary sewer system.
To evaluate existing conditions and potential SWM retrofit scenarios a PCSWMM model was developed to represent 37.4 ha (92 ac) of I/C lands, consisting of thirteen (13) separate property parcels.
This presentation will provide an overview of the approaches taken:
The overarching goal of the aggregated stormwater retrofit study is to support the development of an approach which advances the wide scale adoption of distributed and decentralized stormwater management practices on private property through public/private partnerships.
