section 4 - existing conditions and needs - Martin County, Florida

4.12.3 Sewer System Needs
The majority of the residences/lots within the CRA boundary lack connection to a
centralized sewer system. The exceptions being the Manatee Creek and Murray Cove
neighborhoods, as well as an 8” inch sewer main of Bollard Avenue. There are some
private lift stations for some commercial and institutional buildings. In an effort to
connect the CRA to the South System, a comprehensive wastewater collection system
will have to be designed, permitted, and constructed.
4.13 WATER AND WASTEWATER SYSTEM LEVEL OF SERVICE DEFICITS
Areas currently not served by central water and sewer service are considered to be
deficient relative to the LOS definition. There are a number of areas serviced by 4” inch
and 2” inch diameter water mains. While these lines may be sufficient for providing the
daily needs of the customer, they are insufficient compared to the minimum 6” inch
diameter pipe needed to support basic fire service, unless a hydrant serviced by a 6”
inch line is in close proximity of the structure.
Figure 8, “Existing Water Piping”, delineates the existing central water piping system
within the CRA as reported by Martin County Utilities. The water piping shown in the
exhibit is limited to 6” inch diameter and larger. Areas shown in the exhibit which do not
have existing piping are considered to be deficient in accordance with the LOS
standards.
Figure 9, “Existing Wastewater Piping”, delineates the existing wastewater piping
system within the CRA as reported by Martin County Utilities. The gravity portion of the
sewer system installed does not have any known service deficits. According to the
March 2000 Forcemain System Hydraulic Analysis by Hutcheon Engineers, 100% of the
lift stations within the CRA boundary are able to deliver the required flows during peak
flow conditions.
4.14 LEVEL OF SERVICE RECOMMENDATIONS FOR WATER AND WASTEWATER
Level of Service (LOS) standards for the water and wastewater systems are identified
through a combination of engineering standards, utility purveyor policies, community
practices, and regulatory requirements as presented in Section 3. Throughout the CRA
area (as well as other areas of the County) there are large tracts of land lacking central
water service and rely on individual wells for their water supply. Similarly, there are
large areas which do not have access to a central sewer system and utilize on-site
septic systems to dispose of their sewage.
The intent of the CRA utility redevelopment process is to: provide central water and
sewer service to all parcels within the CRA; provide consistent quality potable water to
all residents; provide sufficient fire flow to respond effectively to emergencies; and,
eliminate operational and environmental problems associated with on-site treatment
systems. Accordingly, the basic LOS standard for all areas within the CRA incorporates
the following:
