Executive Summary and System Recommendations for the Sanctuary Belize Marina and Village Surface Water and Waste Water Management Plan designed to suit and meet required levels of protection and mitigation per the Dept of Environment of Belize Environmental Compliance Plan (submitted and approved) and to meet international standard per UNEP Caribbean Special Protected Areas and Wildlife Act for which Belize is signatory. Areas include mixed residential WWT, land and sea fuel station systems and process, monitoring and protocol

1. MARINA WASTE WATER MASTER PLAN EXECUTIVE SUMMARY –JAN 2014
Waste Water Management Recommendations
MARINA
SECTION 1
EXECUTIVE SUMMARY
The Marina represents the core of mixed-use development infrastructure and services. It will likely
represent the densest zone of population therefore requires special management of waste streams.
Unlike R1 areas where the cost of WWM can be passed to the consumer through micro-systems, the
Marina village will require development-side infrastructure via centralized processing system and
effluent management.
Economically, well-designed waste water management systems can be modular, scalable and enjoy
good scale of economy. In the perfect world a system plugs and plays into an existing framework of
known gallon per day (gpd) feed in a fully populated static environment. However, the marina will
come to life in increments, starting with basic infrastructure for fuel dock, land fuel station, restaurant,
pump-out service, public restrooms and then condominiums. This first phase will roll out over a span of
2 years plus.
Therefore, the waste water system requirement demands a package-system capable of scaling from
relatively few inputs to the ability to manage the fully populated marina village. This must be done
without compromising effluent quality due to the density of population and sensitivity of the marine
ecosystem. Accordingly, Caribbean Special Protected Area and Wildlife best practice recommendations
were used as a reference and a guide.
Fundamental and critical to waste water management systems (large and small) is the minimum and
maximum amount of waste the system is designed to process. In the case of a 2 to 3 year population
growth curve, the chosen system must be able to treat all volumes from the initial quantity of waste,
i.e. the minimum a large scale system can process to specification. Accordingly, a modular scalable
system proved the most effective and cost effective mode of delivery. The counter proposals ruled out
were containerized systems and municipal centralized offsite treatment facilities.

2. The estimated scale-up (turn-up) requirement of the system was based on the metrics of gallon-per-day
output of population (y) versus time based on event milestones over the course of years (x):
Accordingly, even though residential and commercial infrastructure may ramp over the course of
months (commode, sink and slip count), actual waste inputs and initial waste streams (commode, sink
and head use) will likely be minimal, sporadic but increasing. For example, the first townhouses,
marine pump-out and marina public restroom/ kitchen etc, will generate only a few thousand gallons
per day. Townhouses may not be inhabited all year, and likely seasonally. Most centralized scale
systems have a turn-down-ratio that is unable to accommodate such small volumes. Therefore systems
offering an initial footprint that could be scalable were investigated based on the following factors 1)
modular 2) scalable-expandable 3) ability to meet best practice goals (positive natural capital impact)
4) flexibility to take multi-delivery inputs, pressurized and hard-line inputs 5) availability of service,
parts and warranty in country 6) vendor’s willingness to tech transfer the system maintenance,
monitoring and troubleshooting to Belizean work-force (social-impact value addition) 7) simplicity of
design, inputs and economy of scale
ENVIRONMENTAL IMPACT ASSESSMENT ASSUMPTIONS:
Scope Liquid Waste in Marina Village and Marina per the Environmental Impact Assessment
The Development’s ECP is governed by an EIA published in 2003 and updated in 2009. The EIA
forecasted that the Marina Village at complete build-out will be a total of rooms 939 for a total
population of 1409 with a total water consumption rate of 56,360gpd (EIA Table 3.1, 2009).
The Marina Village is sited on 137 acres (EIA Section 2.2.1, 2009) with a total of 218 residential units
and a hotel. (EIA Table 2.1, 2009) The Developer is currently considering the scope of the first phase of
this scope (Marina Village Town Plan, see Annex 2) and encompasses the fuel docks (land and marine),
76 multi-plexes, 13 townhomes, restaurant, public restrooms Development intends to equip the marina
with 150 slips in accord with the EIA Section 2.2.1.2, 2009 . The capacity of the marina is expected to be

3. MARINA WASTE WATER MASTER PLAN EXECUTIVE SUMMARY –JAN 2014
up to 300 boats each with an average waste water storage capacity of 200-500 gallons. Fueling service
will be available at a single point-of-service fuel station that will offer pump-out service via a mounted
pump-out with holding tank that pressure feeds to the mainline to the WWT plant. Offsite laundry service
will be provided in lieu of on-vessel discharge of grey water into the marina.
Projected Sewage: Using the precautionary principle as described in the EIA, 400gpd discharge was used
per person. The Development is requiring single family homes to include tertiary package systems that
can produce Class 1 output effluent (see Annex 1, Figure 1), with the exception of the Marina Village that
will have the centralized modular mainline system described herein.
In the Marina Village and Marina, the EIA recommends the use of a tertiary resort-package modular
treatment system. (EIA Section 4.2, 2009) Recommended post-treatment effluents are BOD 48; COD 119;
Nitrogen 3.2; TSS 90. The community Best Practice goal is SPAW Class 1: TSS 30mg/l; BOD 30mg/l;
FOG 15mg/l; Coli. 126mpn/100ml; (Annex 1) Nitrogen and Phosphates to be taken up through bio-process
gardens (engineered wetland) as has become the industry standard at Caribbean resorts. (Annex 3)

4. Proposed System Design for Phase 1 Marina Village
System Description: The waste water treatment (WWT) system is designed around a modular-scalable
Sequence Batch Reactor (SBR) tertiary resort package system as recommended by EIA Secion 4.2.2
Update (2009). The system outperforms the recommended standard and will be disinfected prior to
discharge to produce best-practice hygienic SPAW Class 1 discharge water to an irrigation pond and public
gardens (evapo-transpiration (ET) field) which will create lush green space, with biota taking up N/P. The
pond will be a functional supply for the community irrigation water demand. (Annex 3). The system
footprint will be potentially scalable to 200% forecasted capacity and provide irrigation water for the
Marina Village. A principle assumption is that the marina will scale over 7-10 years to 100% occupany, eg.
20,000gpd initially to 100,000gpd at full scale based on a 200% precautionary principle. The proposed
system is detailed in Section 2 of this Report.
Boat waste water will be managed via mounted and mobile commercial marine grade pump-out systems.
Wastes will be held at a central holding tank and forced to mainline lift stations to the SBR. In addition, a
Marina and Sapodilla Lagoon education program will be initiated and managed by the marina manager,
staff and prominent signs and notices to include: advising mariners not to pump-out, advising of pump-out
protocol; location of mounted pump out service center; location and scheduling procedure for mobile
pump out service dockside and/or boatside. The proposed system is detailed in Section 2 of this Report.

5. MARINA WASTE WATER MASTER PLAN EXECUTIVE SUMMARY –JAN 2014
Public Restroom waste water will be either tertiary treatment onsite package or forced main pumped to
lift station and ultimately the SBR. In either event the same critical quality effluent will be achieved and
irrigation water used locally for landscaping for further biotic uptake of nitrogen and phosphate.
The proposed system is detailed in Section 2 of this Report and Annex 1, Figure 1.
Storm water run-off at Fueling Station and Parking Lots have a high likelihood of hydrocarbon
(gasoline, diesel, oil) contamination. As such fuel station and parking lots will be graded to channel water
through drains leading to industrial interceptors and drain filter interceptors. These are standard in the
industry and will be monitored, maintained and filter cleaned by trained SRWR Belizean staff. (a positive
social capital/impact value addition) The proposed system is detailed in Section 2 of this Report.
Lastly, per the EIA Update, Section 2.2.5, 2009, a separate dry dock/ corporation yard outside the
Marina will be used for boat maintenance and servicing. No servicing of vessels aside from fuel up and
pump out will be performed in the Marina. The future dry dock facility and corporation yard will be where
bilge, maintenance and other services with a potential for high intensity waste discharge management will
be designed. Therefore, no system requirement is necessary to manage high density liquid waste or
hydrocarbon water contamination related to boat repair or bilge works in the marina area.

Hydrocarbon and Solids ‘Interceptor’ Tank
for Land-side Fuel Station Water Runoff Management
‘Hydrocarbon Interceptors’ collect surface runoff in areas prone to contamination by gas, oil
and petroleum grease. Once captured above or below the clarifying layer hydrocarbons
cannot re-enter the clarifying layer. Most gravity interceptors force the incoming wastewater
stream directly downward toward the floor of the interceptor under the guise of increasing
path length. However this causes a "valley-peak-valley" flow pattern that disrupts the pollutant
layers already stored in the interceptor, pushing them ever closer to the outlet.
Because pollutant layers are stored in
large quiescent zones in the Proceptor,
it is possible to have very large storage
capacities for fats, oil and grease. At full
rated flow, most Proceptor interceptors
and separators can hold between 45% -
50% of their volume in fats, oil, and
grease. See more at:

High Density Polyethylene (HDPE) was chosen as the
appropriate technology for waste water lines due to properties
that mitigate the risk of rupture that could cause contamination
in populated and ecologically sensitive areas. HDPE has
become recognized as a standard in the industry application for

11. MARINA WASTE WATER MASTER PLAN EXECUTIVE SUMMARY –JAN 2014
pressurized waste water installations. Cost effective, on-contour and seamless heat-welded
without couplings provides strength and ease of installation. The SRWR and Developer
procured the full compliment of equipment and technical training enabling installation,
maintenance and monitoring of its own potable and waste water line systems. This creates
a level of security regarding prevention of leakage or rupture due to the nature of HDPE
and the response time of a technically enabled SRWR workforce (a positive social
impct/capital value addition). HDPE is well known for its anti-corrosive, high pressure
tolerance, surge tolerance, cyclic resistant, seamless high flow rate. It makes it the
technically appropriate solution for forced main lift stations that will service an
approximately ¼ mile radius of the main Phase I WWT system. Commercial grade lift
station pumps at the Marina condominiums, mounted pump-out dock, public restrooms
and individual units will move waste water under pressure to the SBR package system
where it will be treated, disinfected and discharged into an irrigation pond, engineered
garden public green space. (see below)
SEQUENCE BATCH REACTOR PACKAGE WWT
The centralized sequence batch reactor (SBR) resort
batch reactor will process the black and grey water
outputs of the Marina Village and Marina pump out
effluents. The SBR is robust technology used throughout
the world and relies on bio-enzyme and natural
biochemistry to treat water for irrigation recycle. The
system contains no filters and requires no chemicals and
works off the natural cycle of aerobic breakdown of
organic wastes. Further the ‘batching’ feature feeds back
bio-enzyme charged water into the anaerobic portion of
the process and thus requires no de-sludging. Due to its modular by design profile, batch
systems easily allow for the addition batch chambers in 5000 - 10,000 gpd increments.
This is ideal for the forecasted build up of the Marina population. This system will be
housed in a structure at-grade, for ease of maintenance, installation and expansion.
11

12. The Marina will be a system mainframe of 10,000gpd able to gradually increase to 50,000gpd and
possibly 100gpd using the ECF-WWTS-Anoxic/Aerobic 10K modular framework.
Stage 1: Receiving/mixing tank - sized for short term expansion with adjustable injection to treatment.
This can be concrete or a battery of 5Kltrs Rotoplas tanks to meet inflow.
Stage 2: Anaerobic - sized specific for 10K gpd increments and grows with expansion (this stage is
critical as it eliminates all foul odors)
Stage 3: Aerobic - sized specific for 10K gpd increments and grows with expansion (flows control is
maintainable for micro organisms digestion)
Stage 4: Clarification - Sized for short term expansion
Disinfection - The type of disinfection will be decided once we know where the treated outflow will be
discharged.
Storage of treated water – may be stored for two days if repairs need to be facilitated at the discharge
lake but will otherwise be discharged into the irrigation lake daily.
Final design will consider the maximum footprint of the expanded platform, made from form concrete
and housed for aesthetics. Tanks will be high density polyethylene, industrial grade R-20, in a three
level platform.

13. MARINA WASTE WATER MASTER PLAN EXECUTIVE SUMMARY –JAN 2014
The envisioned system is currently in use and functioning to specification at resorts in Central America and Mexico . A social-impact
value addition to the system is its ability to be designed, installed and maintained in country by e based companies willing
to tech transfer the monitoring, maintenance and des ign capability to SRWR’s Belizean workforce.

Annex 1:
(Except from Sanctuary Belize Best Practices Executive Summary: Waste Water)
OVERARCHING FUNDAMENTALS OF THE WASTE WATER CRITERIA
Both Belize and the United States are signatories to the United Nations Environment Programme,
Caribbean Special Protected Waters and Wildlife Treaty that will come into effect in 2015. It will
impact the National and CBA waste water output protocols for residential, commercial and ecotourism
in Belize.
Specific to Belize were the findings that its “high water table encourages draining septic tank
effluent directly to canals and ocean for fear of contaminating drinking water supplies” .... as
well as leeching that is causing “high coliform counts in coastal waters.”.
The following excerpts from Article III of the Protocol explain some of the general obligations:
Each Contracting Party shall develop and implement appropriate national plans, programs, and
measures. In such plans, programmes, and measures, Contracting Parties shall adopt the most effective
means of preventing, reducing or controlling pollution from land-based sources and activities on their
territory, including the use of best available technology.
In its national plans, programmes and measures, each Contracting Party shall specifically include
effluent and water quality standards taking into account available national, regional, or global standards
and recommended practices and procedures adapted to national circumstances.

18. Annex 3
Comparable Reference: Carribean Hotel Package Plants
Several large hotels on Caribbean islands
represent a population density too high for
septic tanks to be efficient or economical. To
avoid pollution of nearby bathing beaches,
many of these hotels use small, extended-aeration
package plants.
Of the hotel package plants, the highest quality
effluent was noted at a wetland treatment
system for a medium-sized hotel. The treatment
process includes pre-treatment with screening
and settling. The wastewater then flows into a
three-tiered, free-water-surface wetland system
dug into a hill. The wetland effluent passes
through a filter and then is disinfected with an
ultraviolet lamp. Monitoring data showed that the effluent BOD and
suspended solids concentrations were typically less than 10 mg/L.
The extended aeration package plant is equipped with most of the processes
that an ordinary activated sludge treatment facility uses, but on a smaller
scale. All used a process sequence of screening, followed by an aeration
basin, followed by sedimentation tanks, followed by chlorine disinfection
before discharge or reuse for landscaping. At one of the hotels, an
equalisation basin was provided before the aeration basin. Sludge from the
sedimentation tanks was recycled back into the aeration basins, with the
excess typically wasted to a thickening tank. No design data were obtained
for these plants, but it is estimated that most were designed with capacity to
serve a population of 500 to 2,000.
