SECTION 1
PURPOSE OF AMENDMENT
Introduction
The City of Sanford, City of Lake Mary and Seminole County entered a Tri-Par[y
Agreement regarding use of reclaimed water and surface water augmentation from the
St. Johns River. The Tri-Party Agreement resulted in the supply of an additional 1.113
billion gallons/year of reclaimed water/surface water to the City of Lake Mary and
Seminole County to meet irrigation demands in the I-4 Corridor and to reduce
groundwater withdrawals.
Currently, the surface water augmentation treatment capacity has been increased from
3.65 MGD to 7.3 MGD. Combining available reclaimed water and surface water
augmentation only from Sanford, in excess of 15 MGD of alternative water supply is
available. Seminole County is expanding their reclaimed water system to include
residential irrigation and as such, needs additional and more reliable supplies. The
Cities of Lake Mary and Sanford will also benefit by increased and more reliable sources
of reclaimed and augmentation water supplies, decreasing the use of groundwater
sources and conserving it for drinking water supply. In addition, expansion of recharge
will reduce the impacts of groundwater withdrawals for the Tri-Party.
1.2
Purpose
The purpose of this study is to evaluate expansion of the reclaimed/surface water
augmentation system to maximize the use of this alternative water supply and conserve
our groundwater supplies. The study will result in a Regional Plan for use of reclaimed
water / augmentation water from the St. Johns River. In order to be eligible for funding
of system expansion through the District, a plan must be prepared and adopted as part
of the Regional Water Supply Plan.
The Plan will identify projects in the City of Sanford, City of Lake Mary and Seminole
County for expansion and increased reliability for the system. After adoption of the plan
as part of the Regional Water Supply Plan, the listed projects would be eligible for
various funding sources such as Stag Grants, Florida Forever Special Appropriations,
District Funding, etc.
SECTION 2
PROFESSIONAL ENGINEERING SERVICES
2.1.
In order to optimize the use of the supply of reclaimed water and surface water
augmentation and plan for system expansion, the Tri-Party together with the St.
Johns River Water Management District, have agreed to prepare a Regional
Reclaimed Water and Surface Water Augmentation System Expansion and
-2-
Optimization Study. Under this Agreement, the ENGINEER is to provide the
following services in connection with the Study:
2.1.1. Consider each entity's current plans or needs for reclaimed water. The
Engineer will obtain and evaluate all current Master Plans.
2.1.2. The Engineer will evaluate available resources including:
City of Sanford North Water Reclamation Facility (7.3 MGD)
New Sanford South Water Resource Center (2.0 MGD)
Greenwood Lakes Wastewater Treatment Plant (3.5 MGD)
Northwest Regional Water Reclamation Facility (2.5MGD)
Sanford Reclaimed Water Augmentation System (7.3 MGD)
2.1.3 Identify additional cost-effective uses of reclaimed/augmentation supplies
based on current Master Plans, potential users and available supplies.
2.1.4
Evaluate potential recharge basins. The St. Johns River Water
Management District will utilize the Regional Groundwater Model to
determine the benefits to groundwater supplies based on the additional
recharge and reclaimed/augmentation water application as identified in
the plan. Evaluate development of recharge basins along Rinehart Road
and at the Greenwood Lakes rapid infiltration basins and within the
Heathrow and Timucuan stormwater systems to mitigate the impacts of
groundwater withdrawals from the Greenwood Lakes Water Treatment
Plant, Heathrow Water Treatment Plant, Lake Mary Water Treatment
Plant, Sanford Main Water Treatment Plant and Paola Water Treatment
Plant.
This project will maximize the use of reclaimed and surface water
augmentation supplies available to the City of Sanford, Seminole County
and the City of Lake Mary and will allow for development of recharge
basins to reduce the impacts from current and future groundwater
withdrawals.
2.1.5
Identify potential users of reclaimed water within the Study area as shown
on Exhibit 1. The Engineer will evaluate average daily and peak hourly
flows for the customers. We will utilize an aerial base map and show all
user groups and determine flow demands for the user groups.
2.1.6 Identify flow rates for potential recharge basins including, but not limited
to:
Stormwater ponds at various car dealerships and the Sam's Club
on Rinehart Road.
Stormwater ponds at Woodbridge Lakes, Williston Park and
Wallace Court on Rinehart Road.
Stormwater ponds within HIBC.
-3-
Stormwater ponds within Heathrow subdivision.
Stormwater pond within Timucuan subdivision.
Greenwood Lakes WWTP rapid infiltration basins.
2.1.7
2.1.8
The Engineer will coordinate with SJRWMD Staff for modeling of the
reclaimed irrigation sites and recharge basins to determine capacities and
the benefits, on a regional basis, of recharge on available groundwater
supplies. The regional model will optimize the location for recharge
basins and establish the reduction of impacts caused by groundwater
withdrawals due to reuse and recharge. The modeling will determine
additional safe yields of groundwater supplies based on the increased
reuse and recharge as identified herein.
Based on the optimum locations for the use of reclaimed water and for
recharge and the average daily, maximum daily and peak hourly flows,
the Engineer will update the regional hydraulic analysis of the distribution
system. The Engineer will coordinate with the Tri~Party to develop a
schedule for use of the available water supplies to maximize the use of
the infrastructure:
Filling of storage facilities at Mayfair, Timacuan, Heathrow,
Alaqua, Alaqua Lakes and Magnolia Golf Courses to occur during
the day
Filling of storage at repumping stations at Mayfair, Greenwood
Lakes, and Hanover to occur during the day
Recharge basins to be filled during the day
Irrigation of commercial and residential establishments, etc.,to
occur at night, 2-3 times per week based on a developed schedule
This operating schedule and how the compliance with the schedule is
enforced will be a key to maximize the use of the reclaimed augmentation
supplies. Based on the hydraulic analysis, required system
improvements will be identified including, but not limited to, the following:
2.1.9
Distribution system improvements
Storage
Pumping station upgrades at all pump stations supplying the
distribution system.
Based on increasing use of the surface water augmentation facilities,
reliability of the system will need to be increased to ensure that reclaimed
water is available when needed. In addition, increased reclaimed water
augmentation supplies will be needed to meet all of the future demands
within the Tri-Party area.
The Engineer will evaluate the augmentation treatment system to
determine improvements needed to allow the augmentation system to
operate at times when the Sanford North WRF effluent does not meet
-4-
2.2
reclaimed water standards. Currently, the waters are blended after
filtration, so if the effluent is out of compliance, no water can be delivered
to the reclaimed water system. These improvements would increase the
reliability of the system by having two independent treatment trains
supplying water to the reclaimed ground storage tanks so if one tretment
train is out of compliance, water from the other train source can still be
delivered to the reclaimed water system.
Improvements to storage facilities and the reclaimed water distribution
pump station atthe Sanford North WRF will also be evaluated.
2.1.10
A desktop evaluation of the impacts of the increased use of water from
the St. Johns River for reuse and recharge on groundwater quality will be
prepared. We will utilize available water quality data for the St. Johns
River and groundwater supplies in the analysis. No additional water
quality testing will be provided. Impacts from rainfall and stormwater
runoff will be considered. The St. Johns River Water Management
District will provide any groundwater modeling in support of the desktop
analysis.
2.1.11
Available supplies to be delivered beyond the boundaries of the Study
Area, as shown in Exhibit 1, will be evaluated to determine if further
expansion of the Tri-Party Regional Reclaimed Water System should be
evaluated. Recommendations regarding further expansion of the system
will be included based on the results of this study and input from the Tri-
Party members and the District.
Based on the above, the Engineer will prepare a Final Report including, but not
limited to, the following:
Study Area
Reclaimed Users
Discharge Basins
Current and projected flow rates for the system
Distribution system / improvements/hydraulic analysis
Available reclaimed and augmentation supplies
Recommended system improvements
Opinion of probable construction costs for all potential
improvements
Operating schedule for reclaimed/augmentation water use
Desk Top Evaluation of water quality impacts from increased
augmentation use
Modeling results provided by the District including the estimate of
the increased groundwater supplies available to the Tri-Party
based upon implementation of system improvements. Long-term
safe yields will be estimated to allow increased long term
allocations under each party's CUP based on the study and
District input.
