IRCDUS Septic to Sewer Conversion Evaluation
I. BACKGROUND:
On March 8, 2016 the Board of County Commissioners(BCC) authorize staff to further refine the ranking matrix
based on additional criteria, prepare cost estimates for the ranked areas and a TN/TP removal cost. On
November, 2013 the BCC approved two (2) sewer feasibility studies. The two studies targeted different
geographical areas in the unincorporated Indian River County. The study labeled "Summerplace" is located on
the north side of SR-510 between the Atlantic Ocean and Indian River Lagoon. The second area studied was
labeled "North Sebastian Area" generally described as having a western limit of US Highway 1, an eastern limit
of the Indian River Lagoon, a Northern Limit of Indian River Drive connection to US Highway 1, and the Southern
Limit as Main Street. During the same time many researchers were also studying the effects of Onsite Sewage
Treatment and Disposal Systems (OSTDS) nutrient loadings causing algae blooms in the Indian River Lagoon.
The capital cost of converting septic to centralized sewer is an expensive undertaking as shown in the two
feasibility studies. Therefore, Indian River County Department of Utility Services (IRCDUS) staff decided to
evaluate a ranking mechanism based on several criteria. The primary goal of the two feasibility studies were
conducted to address the health of the Indian River Lagoon (IRL). The North Sebastian study in addition to the
health of the IRL also focused to maximize economic development and job creation along the US Hwy 1 corridor
in Sebastian.
The goal of the evaluation is to prioritize the areas based upon various physical and environmental factors
and determine the feasibility of incorporating the proposed systems into the 10 year Capital Improvements
Plan. The responsibility of an un-biased ranking system utilizing the physical and environmental factors as
justification will be the responsibility of the CONSULTANT.
Upon completion of the prioritization and ranking of the areas, CONSULTANT will evaluate the installation
of sanitary sewer collection system and provide an estimated cost for the installation of the recommended
improvements to the nearest existing sewer. As the individual areas are evaluated,CONSULTANT will
calculate the wastewater flow rate for these areas.
The CONSULTANT will then prepare a report summarizing the findings of the study. The results of the
prioritization and rankings will be presented in a tabular format along with the preliminarycost estimates
for each of the top 30 ranked areas.

II. SCOPE OF SERVICES:
Phase I: Evaluation and Rankine
1. Initial Ranking (Aquatic Health)
CONSULTANT will review the existing analyses the COUNTY has performed, analyze existing historical utility
records, existing as-built's, utilize the Indian River County Utilities Geographic Information Systems' (GIS) data,
and utilize other maps, records, reports and documents pertinent to this study. The CONSULTANT will use this
data and develop a rational numerical indexing system of physical and environmental factors that influence the
potential discharge of nutrients from existing OSTDS and its migration through sub-surface and surface waters
to the Indian River Lagoon and its tributaries.The CONSULTANT will derive a mathematical formula and develop
spread sheets which enable a numerical analysis of these factors that will result in the ranking and prioritization
of the conversion of approximately 345+- geographic areas in IRC that currently utilizing onsite sewage
treatment and disposal system to centralized collection and treatment sewer utility system. It is anticipated that
the numerical prioritization will be based upon at least the following physical and environmental factors for
determining the initial ranking and prioritization:
• Population Density for Loading Concentrations
• Proximity to Surface Waters
• Location of the Community in Relation to the 100-year Flood Plain— FEMA Flood Plain
• Depth of the Ground Water Table
• Soil Conditions of the Drain Field —Soil Type
• Age of the Surface Water Management System
• Age of the Existing OSTDS
The soil type and water table will be determined by referencing published geotechnical data obtained from the
USDA-Natural Resource Conservation Service Soil Survey and other available information, and existing survey
or GIS data that may be provided by IRC. No new survey or Geotechnical field work will be obtained.
COUNTY staff has already prepared an initial/ preliminary evaluation and researched some of the parameters
mentioned-above. This information will be made available to the CONSULTANT in order to keep man-hour cost
down. However, it will be the responsibility of the CONSULTANT to verify the accuracy of the provided
data/information.
As part of the evaluation the study area will be restricted to the Indian River County Utilities Service area within
the Urban Service Area (USA). Furthermore, the evaluation will be limited to areas with clusters of existing
OSTDS and not large individual parcels with existing OSTDS.
The top 30 areas identified in this initial ranking (areas of highest priority to convert) will be included in further
evaluations as outlined below.
2. Sanitary Sewer System Evaluation and Cost Estimate
CONSULTANT will review various types of sanitary sewer collection and transmission systems, including gravity
sanitary main sewer collection system with conventional lift station, vacuum sewer collection system with
vacuum pits and pump station, and low pressure force main with individual grinder stations for each of the 30
2
areas and provide an estimated construction cost. The cost per unit (existing home site / or buildable lot) will
be determined for each geographic area.
3. Final Ranking
The CONSULTANT will derive a mathematical formula and develop a spread sheet which enables a numerical
analysis of the following data to arrive ata Final Ranking and Prioritization of the conversion of the 30 geographic
areas:
1. Aquatic health (results of the Initial Ranking)
2. Sewer System Evaluation and Cost data
3. Estimate the Total Nitrogen and Total Phosphorus removed /Cost per Ib. removed
4. Public health -Availability of a Public Potable Water Utility System
Phase II: Master Wastewater System data
CONSULTANT will provide estimated average and peak flows generated by each of the 30 priority areas to the
COUNTY (based on 10 state standards). This information will be provided for COUNTY's inclusion in its
development of its Master Wastewater System.
Phase III—Report Preparation
CONSULTANT will summarize the findings of the Analysis/Prioritization, Individual Area Sanitary Sewer System
Evaluation, and the Master Wastewater System Evaluation in a report.The report will include a summary of the
approach used to determine the priority areas to be converted from onsite septic system to sanitary sewer. A
table of the priority rankings for the areas of the study and the estimated construction costs for each of the
areas will be provided as an appendix to the Report.
CONSULTANT will evaluate the total nitrogen (TN) and total phosphorus (TP) removed from the conversion of
septic to sewer for each of the 30 priority areas and compute a cost per pound for TN/TP removal. CONSULTANT
is to compare these cost per pound removed to other projects such as the existing Algal Turf Scrubber (Osprey
Marsh, Egret Marsh) projects, Spoonbill Marsh, PC main projects and any other innovative TN/TP removal
projects. The COUNTY will provide the CONSULTANT with TN/TP removal numbers for the projects installed
and operated by the COUNTY.
