Project Description:

 

 

 

 

 

 

 

The objective of the following legislative appropriations summary is to propose an increased role for the City of Coconut Creek in the state-wide effort to upgrade existing non-point source (NPS) management programs in accordance with the Clean Water Action Plan.  It is proposed that the City of Coconut Creek obtain state funding in order to implement in-house storm water/wastewater  modeling in cooperation with Broward County Office of Environmental Services (BCOES) and the South Florida Water Management District (SFWMD).  It is proposed that the city shall create the spatial geometric model of the existing storm water and wastewater features, fully attributed with required model parameters.  This creation process is proposed as a combined effort involving the implementation of a sub-meter GPS program and in-house digital mapping.  Once created, various storm water and/or wastewater loads are to be applied with custom peaking factors to the Total Maximum Daily Load (TMDL) contributions.  Open channel and closed conduit flows may be modeled, system adequacy determined, and flow hydrographs and stage-storage curves generated.  The City will then have a Geographic Information System (G.I.S.) interface to the U.S. Environmental Protection Agency's SWMM model, thereby integrating modeling and G.I.S. technology. 

The proposed project can be divided into three essential components:

1)         Implementation of a sub-meter accuracy GPS program for the collection of storm water and wastewater features

2)         Incorporation of physical system characteristics into a final functioning model

3)         Simulation of key scenarios in order to evaluate system adequacy and response to various imposed storm water/wastewater loads.

Services Provided/Benefits:           It is currently estimated that the City of Coconut Creek spends approximately $150,000 annually as a result of wastewater inflow and infiltration (I/I) during storm events.  These costs are incurred as a result of the fees imposed by Broward County for the treatment of this portion of the City?s total estimated 5.0 to 5.5 MGD (million gallons per day) of wastewater discharge.  The proposed project would provide a means by which to simulate wastewater inflow and infiltration during storm events, and hence, the delineation and assessment of I/I problem areas)The benefits of GPS technology are numerous, in addition to being essential for the successful implementation of this proposed project.  Approximate relative locations of the key features listed below, can be identified from final engineering as-built drawings and given precise positional locations via field visitation with a GPS receiver.

?          storm drains, storm water inlets and storm manholes

?          storm water outfalls to lake/canal outlets

?          culvert endpoints

?          sewer force main plug valves for line isolation

?          Sewer manholes

 

The resulting accurate digital mapping product will then be comprised of an updated inventory of structures.  The digital maps will be simple to update and correct and form the basis for system analysis and management.  A chronological history of activities and work orders performed on the system can be additionally related.

Physical system attributes are incorporated into the digital map via a combination of both field input at the time of GPS point capture and office input as per final as-built drawings.  The incorporation of this digital data into current storm water/waterwater modeling software results in the actual working model.  Once calibration and verification of the model is performed (comparing known flows with model predictions), the final functional model results.

Simulation of key scenarios in order to evaluate system adequacy and response to various imposed storm water/wastewater is the final goal of this proposed project.  The resulting reports will prove to be extremely useful at both the county and city levels.  Internally, the functioning storm water/wastewater model can then be utilized to assist in hydraulic analysis, management of line rehabilitation and I/I projects, management of storm water and sewer maintenance programs, and even emergency response requirements.

 

 

 

 

 

 

 

 

 

 

 

 

Measurable Outcome Anticipated:

 

 

 

 

 

1) identification of storm water handling capacity (i.e., system inadequacies), 2) creation a sub-meter accuracy digital map of existing storm water and wastewater point features to aide in emergency response activities, 3) provide detailed city-wide flow hydrograph and storage flow estimates to the Broward County Office of Environmental Services and the South Florida Water Management District.
