REQUEST FOR PROPOSAL
Sanctuary Belize Marina Village
Mixed-Use Commercial/ Residential Scale
Package-Waste-Water-Treatment-System with Class 1 Effluent
Introduction:
The Marina Village represents the core of mixed-use development infrastructure and
services at Sanctuary Belize, Stann Creek, Belize. The Marina is being considered for
management by IGY http://www.igymarinas.com and must therefore be international
standard and exhibit best of breed systems and practices. The Marina Village will
represent a dense zone of population, situated adjacent to mangrove lagoons and the
open Caribbean and therefore requires special management of liquid waste streams and
treatment to Class 1 without odor. Marina Village will require development-side
infrastructure via a centralized scalable processing system and effluent management. (see
Exhibit 1 & 2)
This RFP is for the installation of a well-designed package wastewater management
system that is modular, scalable, easily manageable and enjoys good economy of scale.
The preferred system will be one that will stub from the planned sewage infrastructure
based on estimated gallon per day (gpd) inputs that will begin small and over the course
of five to ten years evolve to into a fully populated environment. (Exhibit 4)
Therefore, the selected Waste Water Treatment (“WWT”) system must be a package-system
capable of scaling in stages from relatively few initial influents, to the influents
forecasted for 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. The effluent criteria set forth in the Govt. of Belize Department of
Environment Sanctuary Marina ECP, UNEP Caribbean Special Protected Area and
Wildlife Best Practices Recommendations and Sittee River Wildlife Reserve WWT
(Waste Water Treatment) Best Practice Guidelines are used as the performance metric
reference.
***
Statement of Project:
This Request for Proposal (Scope of Work) is for the design, installation and
commissioning of a scalable turn-key package WWT System to include the technical
transfer of the system’s operation and technology that would provide Sittee River
Wildlife Reserve the ability to manage, monitor and maintain the system into perpetuity.

2. Sizing Details and Assumptions Overview:
The Marina Village is sited on 137 acres with a total of 218 residential units and a hotel.
(Exhibit 2). The Developer is currently considering the scope of the first phase of this scope
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 Master ECP. The capacity of the marina is expected to be up to 300 boats
each with an average wastewater storage capacity of 200-500 gallons. Offsite laundry
service will be provided in lieu of on-vessel discharge of grey water into the marina.
(Exhibit 1). However residences can be expected to each have their own laundry grey water
outputs that will be comingled with black waters and low pressure fed via lift stations to the
subject WWT facility.
Projected Sewage Assumption: Using the precautionary principle as described in the EIA,
400gpd discharge was used per unit.
Effluent Metrics: In the Marina Village and Marina, the EIA recommends the use of a
tertiary resort-package modular treatment system. The SRWR community Best Practices
Benchmark is UNEP C-SPAW Class 1 effluent with the following profile:
BOD 15-30mg/l;
FOG 15mg/l;
Coli. 126mpn/100ml;
TSS 30mg/l
Nitrogen & Phosphate reduced by +50% via engineered bio-retention gardens/ponds
Waste Source/Type Assumptions: See reference, Exhibit 1.
Proposed System Design for Phase 1 Marina Village
Scope of Work: Design, Install, Tech-Train and Commission the following:
System Description:
The required WWT system should be a modular-scalable Sequence Batch Reactor
(SBR) tertiary resort package type system as recommended by Master EIA/ECP.
The system will meet the above-referenced standards metrics and must be
disinfected prior to discharge into an irrigation pond /integrated public gardens
(evapo-transpiration (ET) field) to create lush green space, landscaped with biota

3. selected to take up N/P. (see Exhibit 3) The pond will be a functional supply for the
community irrigation water demand. Note, the pond construction will be specified
under a separate RFP. The current RFP is for the SBR system design, purchase and
installation.
Delivered System Scalability:
The system must be potentially scalable to 200% forecasted capacity and provide
irrigation water for the Marina Village. (Exhibit 4). A principle assumption is that
the marina will scale over 7-10 years to 100% occupancy, eg. 20,000gpd initially to
100,000gpd at full scale based on a 200% precautionary principle. Preference is for
“bolt-on” expandability: Each system phase should be plumbed so as to anticipate
and easily add modules when additional capacity is required. The forecasted
expansion plan is as follows:
Four (4) Stage Scale – Up:
Phase 1 (Year 0-2): 1000 – 10000 GPD
Phase 2 (Year 3-5): 10000 – 40000 GPD
Phase 3 (Year 6-10): 40000 – 80000 GPD
Phase 4 (Year 11+): 80000 -120000 GPD
Other considerations for the chosen system will include the requirements re:
maintenance, service, warranty, monitoring, chemical inputs, tech-transfer,
simplicity of design, parts replacement availability, levelized cost, use of similar
systems in Belize/ Caribbean/Central America.
Footprint:
The System that best fits within the master-plan dimensions for the Marina
Village Organic Park design will be a major factor to awarding the contract.
The system must be scalable and compact as it is anticipated that it will be
eventually housed in an aesthetically designed structure at the gardens (designed
and built by others.) The total footprint of the system (Phase 4) should be no more
than, and be able to be installed on a cement pad with a building façade (by
others) as a shell. (See concept drawing, Marina Village Organic Park and
Gardens.) The total gross footprint of the built-out system should not exceed
40’L x 20’W x 18’H and be able to be housed inside a ventilated structure.
The building shell architecture will be designed by others, and will integrate with
the proposed system layout. It is assumed that some sort of WWT/Irrigation
facility management office will be incorporated into the building.
Influent:
Influent assumption is standard residential black and grey water, delivered via

4. grinder-pump as well as marine vessel black water pump out. Inflows (system to
be delivered by others) via a low pressure HDPE system. Developer will daylight
the stub four feet (4’) from the proposed building foundation for the Contractor’s
connection to the system intake.
Effluent:
The System that achieves the best quality effluent with the least amount of
filters, chemical inputs, noxious outputs and monitoring requirements will be a
major factor to awarding the contract. Outflows to be stubbed into the irrigation
pond adjacent to the proposed system site. Contractor will stub out effluent line
within 4’ of building foundation with a check valve for Developer’s connection to
the effluent pond.
Connections:
Plumbing and Electrical connections within the facility should be plug and play
by the Contractor. The Developer will provide appropriate power and water
connections to the Contractor’s stub outs within 4’of the building footprint.
The Developer will be responsible for obtaining the appropriate electrical permits
and permit fees for the system based on the Contractor’s load calculations and
requirements.
The Contractor will be required to be present during the final electrical connection
and electrical system energizing by BEL.
Maintenance:
Preference will be given to systems and vendors with a history of use,
installation, parts, service, running-cost, monitoring and maintenance of the
specified system in Belize. The scope of work includes the entire maintenance and
monitoring technical transfer and should include the expected training program
specifics with SRWR staff assigned to monitor, maintain and repair the system.
Bids should include this aspect as a separate line item the technical and cost of
including telemetric monitoring for decentralized management of the system.
Schedule:
Bid should identify the estimated Phase 1 construction duration including material
procurement. (itemized)
Bid should be valid for one (1) year.
System shall be selected within 120 days of Bid receipt.
Additional Considerations:
Verifiable Quality of Effluent; Preference for Bio-Enzyme/ bio-mimicking
treatment processes versus chemicals and filters; running cost; ease of tech

5. transfer and use of systems in Central America/ Caribbean or Tropics; potential
for odor and mitigation; ease of installation; availability of parts; design to fit
master planned dimensions; telemetry (decentralized online monitoring
capability); manufacturer warranty/maintenance warranty, and availability follow
up training/monitoring are all part of the evaluation for bid award.
Proposal Format:
Bid should be on company letterhead in BELIZE DOLLARS and include the
Excel spreadsheet template quote breakdown (Exhibit 5) specifying landed cost of
goods, i.e. inclusive of shipping, brokerage, customs/duties, delivery to site,
customs, and GST, etc., as outlined in the attached Bid Schedule of Values. THE
BID SCHEDULE OF VALUES (SOV) MUST BE USED FOR YOUR BID.
Your own back up may be submitted in conjunction with the SOV as needed.
ALL system information you provide us must include the following at a
minimum; 1) Product Description (AutoCAD)/ Verified Performance Data sheets;
2) Maintenance Schedule/Tech Transfer Description, Training Costs, Human
Resource Requirement to Maintain and Monitor, availability of OEM parts,
supplies and service in-country (BZ); 3) Complete Quote of turn key cost,

Scale-­‐Up
The
estimated

(turn-­‐up)
requirement
of
the
system
was
based
on
the
forecasted
metrics
of
gallon-­‐per-­‐day
output
of
population
(y)
versus
time
based
on
event
milestones
over
the
course
of
years
(x).
The
following
are
the
actuals
for
which
a
precautionary
rate
of
200%
was
added:
The
centralized
sequence
batch
reactor
(SBR)
resort
batch
reactor
will
process
the
black
and
grey
water
outputs
of
the
Marina

by
design
profile
should
allow
for
the
addition
batch
chambers
in
5000

10,000+/-­‐
gpd
increments.
This
scalability
is
required
for
the
forecasted
build
up
of
the
Marina
population.
This
system
must
be
housed
in
a
structure
at-­‐grade,
for
ease
of
