PROJECT SCOPEThe Puerto Rico Aqueduct and Sewer Authority (PRASA) was founded in 1945 and provides water and sewer services to 1.2 million inhabitants distributed over 3,500 square miles throughout the island. PRASA owns, operates and maintains a vast and complex utility that consists of: 20,000 miles of pipe, 113 water ﬁlter plants, 249 water wells, 8 dams, 1,560 water tanks, 1,977 pump stations and 51 wastewater treatment plants, servicing major urban areas and remote rural locations. As indicated in PRASA’s Five-year Strategic Plan (2021-2025), the authority faces increasingly complex challenges such as: ﬁnancial constraints; aging infrastructure; sparsely populated areas distributed in zones with highly distinct conditions; vulnerability to severe weather events (droughts; two major consecutive hurricanes, earthquakes); and the COVID-19 pandemic. However, PRASA has developed a proactive approach to tackle these challenges by implementing a Capital Improvement Plan (CIP), which will ensure recovery and enhance resiliency while continuing to abide by its mission of providing high quality water and sewer service at the lowest cost possible. The Strategic Plan estimated that approximately $3.7B are needed for resiliency projects in addition to the $760 MM required to repair damaged infrastructure after hurricanes Irma and Maria in 2017. The Federal Emergency Management Agency (FEMA) through the Accelerated Obligation System (FAAST) has granted PRASA $4.2 B for permanent repairs and damage mitigation projects that will provide solutions to the challenges faced by PRASA within its infrastructure, as indicated in the 2021 FAAST Workplan. Of these projects, approximately $882MM have been assigned to water treatment plant projects, with approximately $400MM to be allocated in the near term (2021-2023). One of these high priority projects is the CIP 5379002 Floating Raw Water Intake at the Guajataca WTP, Quebradillas (FAAST-25), with a total FAAST estimated budget of $8.8MM. In 2020, PRASA issued an RFP/RFQ to secure the services of qualiﬁed engineering ﬁrms to serve as the Program Manager Consortiums (PMC). Arcadis Caribe PSC is one of the PMC and has been tasked to undertake some of the CIP projects under the FAAST initiative, Hurricane Maria 2017 at landfall.

15O3being one of these projects the New Guajataca WTP Floating Raw Water Intake. As such, the PMC has issued a request for proposal for Consultants to provide a technical and economic proposal for the required engineering and design services to complete this project.The Guajataca WTP Raw Water Intake (RWI) is located at PR-119 in the Municipality of Quebradillas. The raw water intake feeds the Guajataca Water Treatment Plant. The Plant obtains its raw water from the intake facilities at the Guajataca Reservoir. The overall Plant and intake location of the Reservoir are presented in the ﬁgure below.On Friday February 18, 2022, 300 PR sta conducted a site visit to obtain ﬁrsthand information regarding the project goals and improvement needs. This site visit was attended by the PMC and PRASA sta. 300 PR has compiled all information obtained from the PMC, as-built documents, and the site visit to develop the Project Scope items that are the foundation of our technical and economical proposal.

With a normal capacity of 34,200 acre-feet, and a maximum depth of approximately 65-feet, the Guajataca reservoir serves as a reliable water source for most of the population in Northwest Puerto Rico. The reservoir provides three raw intakes for the WTP (1) the freshwater intake tower, 2) a 2.0 MGD ﬂexible ﬂoating pipes & pneumatic pumps (currently out of service), and 3) a temporary by-pass/emergency pump station supplying raw water from the existing diversion channel near the WTP.The intake tower and ﬂoating intake pump ﬂows were directed from the reservoir to a PREPA-owned valve house via a 48-inch diameter and 12-inch diameter transmission pipelines, respectively. The existing pumping system includes a raw water ﬂexible ﬂoating pipe intake and a pneumatic vacuum pumping system. Upon suctioning from the reservoir’s ﬂoating intake system, raw water was conveyed via 12-inch ductile iron pipe (DIP) through a pneumatic pump station to the valve house. This 12-inch transmission pipe is approximately 480 meters in length, with underground and above-ground segments. At the valve house, water is diverted as needed to the WTP via 18-inch diameter pipe and the excess ﬂow continues through the derivation channel to serve the towns of Aguadilla and Isabela for potable water and irrigation purposes. The pictures included illustrate the current conditions of some key intake components.

17O3During dry/wet season variations in the water levels in the reservoir began to impact the raw water intake’s infrastructure. Particularly in the dry weather season, the levels in the reservoir would lower, and directly impact the existing raw water intake ﬂexible ﬂoating pipe. In 2016, the 2.0 MGD ﬂoating intake systemn at the reservoir became inoperable after frequent issues, leaving the WTP with only two (2) functioning water intake systems. Some of the major issues reported by PRASA that aect the raw water intake infrastructure were clogging, odor and excessive manganese concentration, causing continuous disruption to the system’s operations. As indicated by PRASA during the site visit, the main challenges the WTP faces are low reliability of the water intake facilities and raw water quality issues with high concentration of manganese, bad taste, and odor control issues when supplying the Plant with raw water from the intake tower. Furthermore, it was noted that during certain times of the evening, suspected ﬁsh spawning near the tower further complicated water supply reliability, as sta would have to disrupt operations for maintenance. When the prior ﬂoating intake was in use, variations in the reservoir’s water levels severely impacted their pumping capacity.PROJECT

Page 18

Therefore, the main objective of the project is to increase reliability of the Guajataca WTP raw water supply system with the installation of a new self-contained ﬂoating pump station with high eciency submersible pumps and related appurtenances that can adequately respond to varying water surface elevations in the lake. These eorts will in turn create a reliable source of raw water while minimizing potable water service disruptions, that were often caused by clogs and impaired water quality at the raw water intake. A new self-contained surface water ﬂoating intake pump station with high eciency submersible pumps and ﬂotation devices will provide a reliable water supply and greatly improve the WTP’s operating eciency. At the properly designated depth, the new pumps’ suction cone of inﬂuence will have to be designed and placed considering the Guajataca Lake’s historically low water surface levels, to ensure a safe and reliable water supply for the population it serves. Over this past year, it can be observed from USGS reservoir data that the water surface elevation varied as much as approximately 18-feet, as indicated in the graph included herein.Existing ﬂoating raw water intake

19O3PHASEO1Raw Water Intake at ReserviorRaw Water Intake at Derivation ChannelPROJECTSCOPEPHASEO2The following sections present a detailed list of scope items per main process element to consider in the project. Phase 1 - Raw Water Intake at ReserviorScope Items as Identiﬁed in the RFP:• Provide self-contained ﬂoating pump station with high eciency submersible pumps with a 3.5 MGD capacity, transmission pipes, and ﬂotation assembly• Provide discharge pipeline and appurtenances to transfer raw water from the ﬂoating pump station to the shoreline site• Provide a shoreline manifold to connect the discharge pipes from the ﬂoating station to a transmission pipe in the shoreline• Provide electrical building to house a new Motor Control Center (MCC) above the 100-year ﬂood level; include emergency generator unit (EGU) with a 5-day diesel reservoir capacity• Provide electrical infrastructure to supply power to the new electrical control room from the nearest PREPA infrastructure• Consider raw water quality improvement technologies for manganese, taste, and odor control• Provide ﬂowmeter and required I&C appurtenances for local and remote monitoring and control for the new raw water pumps station• Provide a transmission pipe from the shoreline connection manifold until the existing raw water inﬂuent pipe located near the PRASA Control Room in the lake shoreScope Items as per 2/18/2022 Site Visit:• As discussed with PMC and PRASA, the preference is to propose a submersible pump system with ﬂotation devices that can provide the 3.5 MGD water supply that is easy to operate, maneuver, and cost eective. This will be critical as performing maintenance to the existing pump and motors is a dicult task due to how inaccessible the equipment currently is. Dierent scenarios will be evaluated to determine pump intake placement in relation to lake depth, water level data, manganese & odor issues, and vulnerability to hurricane season, among others• PRASA indicated 900 gpm per pump could be achieved with quality surface water for best operating point, with a low of 600 gpm achieved when low water levels in reservoir are present This will need to be conﬁrmed based on capacity analysis to be conducted during the project.Proposed MCC Building AreaTypical Floating Pump Station SystemTypical Pipe Float Assembly

• The PMC indicated that the potential location for the new MCC would be located adjacent to road PR-119 at an elevated area southeast of the current intake area. The evaluation of ﬂood levels is critical to housing a safe and protected MCC and EGU area for the proposed submersible pumping system. • PMC and PRASA indicated that the new improvements to the raw water intake shall consider measures to reducing manganese, taste and odor problems as frequent issues at the raw water intake disrupt treatment operations. In general, manganese concentration is reduced by chemical precipitation, chemical adsorption and/or oxidation by aeriation. Of these technologies, aeriation will be the least disruptive to incorporate in the lake as it would not require the installation of a new treatment process. The other two options will be better incorporated at the plant level, which would not solve manganese control issue at the water supply system. Several aeriation technologies can be evaluated, such as surface aerators or bubbler systems, which would depend on the lake hydraulics and depth of water column. In addition, raw water quality analysis is recommended. As manganese concentration is seasonal, it would be optimal to conduct quality analysis during dry and wet weather conditions. However, due to the expedited nature of the project, water quality analysis can be done at the onset of the project and use the data collected to better inform the selection of the solution for manganese control at the water intake facilities. Water quality analysis shall evaluate: Mn, Fe, pH, suspended solids, turbidity and DO. Several options for odor and taste issues will be evaluated. Aerator feasibility will be considered at the intake tower and ﬂoatable pumps intake.• PMC stated the need for SCADA system for ease of operation and control of new raw water intake submersible pumps.• The PMC stated the proposed piping route from the new submersible pump intake to the WTP should be considered to avoid the existing emergency spillway. Phase 2 – Raw Water Intake at Derivation ChannelScope Items as Identiﬁed in the RFP• Provide a permanent secondary raw water source from the derivation channelScope Items as per 2/18/2022 Site Visit• The PMC stated that PRASA would like to make the secondary raw water source near the WTP more robust, by adding a structure to house a new 1.5MGD pump with appurtenances. This would include a permanent intake connection to the derivation channel for quick functioning should an emergency arise. The pump would be connected directly to an above-ground feeder pipe that connects to the WTP, for use when necessary.Additional Scope Items Include:• To consider treatment technologies to reduce manganese concentrations, and mitigate odor and taste concerns, it will be imperative to perform a representative water quality analysis.• Design of an aeriation system at the intake tower and the proposed submersible pump system.Existing Emergency Pump Adjacent to Derivation Channel

These result in a thorough quality plan that the PMC and PRASA can rely on with conﬁdence. We conduct constructability & O&M reviews during each design phase to implement straight forward processes for operators and accelerate construction without impacting operations. In addition to the deliverables, this Team will provide you with quality control documents at every milestone review, from conceptual design, all the way to the preparation of construction documents and speciﬁcations. If approved by the PMC, we propose the implementation Bluebeam Revu as our main tool to monitor and achieve the maximum quality that PRASA deserves. We will also integrate our quality assurance and quality control practices into the PMC and PRASA’s protocols for project delivery. Beyond just checking and reviewing of drawings, our quality program includes incorporating meetings with engineering and O&M sta to solicit and gather their input, which will lead to preparation of submittals that satisfy the needs of PRASA for the new Guajataca WTP Water Intake. Formal Design Workshops, deliverable review meetings and comments disposition management will allow the PMC, PRASA and 300 PR ensure that proper feedback is provided and implemented during the design process. In addition to developing a speciﬁc Quality Plan with the PMC and PRASA at the onset of this project, we will also request our expert Sub-consultants to complete and submit their Quality Assurance Plan, which will be aligned with 300 PR processes and quality expectations. DESIGN QUALITY CONTROL (QC) Each member of the project team is required to comply with the QC procedures. At speciﬁc milestones identiﬁed at the beginning of each assignment, reviewers will be required to document the review comments, sign-o on completion of the deliverable(s) and place a record of the review in the project’s quality review records ﬁle. Each member of the project team is encouraged and expected to inquire of the Design Manager regarding any tasks that may be unclear or require additional clariﬁcation. The Design Manager is to keep the designated QC reviewers for the project appraised of the project progress and is to ensure that all deliverables and work products receive timely reviews by the QC reviewers. Quality is paramount for 300 PR and all our sta members.PROJECT REVIEWS Prior to submittal of major deliverables, the Quality Assurance (QA) reviewer will conduct an independent review of the deliverable. This is in addition to routine QC reviews that are conducted throughout the design process. Any work that does not meet internal quality standards will be noted and changed accordingly. Subsequent to the reviews, the Design Manager will prepare documentation recording the basis of the reviews, the speciﬁc items that were reviewed, the ﬁndings of the review, and any follow-up required.

The following is the list of existing Quality Levels for the diverse utility mapping tasks possible under this discipline: Quality Level D – Typically referred to as the research and consultation of the diverse sources of records and maps and reporting them to the project owner or Engineer. Quality Level C – This level adds the survey of the assets based on the above ground evidence. This includes the location of poles, manholes, hydrants, etc., graphically represented in the context of existing records. Quality Level B – This level adds to the record research and land survey, the designation of underground assets by means of diverse forms of induction, including but not limited to sound and electromagnetic induction, ground penetrating radar, etcetera. Quality Level A – This level of survey adds the physical uncovering of assets for verification by various means including but not limited to hand excavation, vacuum excavation and others. This level provides the highest level of accuracy and is the most expensive modality of utility surveys The present task is proposed to Quality Level C accuracy. The result of the subsurface survey findings will be included in the project deliverables. Client to provide all historic information on site assets. Limitations and Disclaimer – Subsurface Utility Surveys (SUS/SUE) bring a significant benefit to asset owners, contractors, and other entities in the manner they point out existing underground assets to be conserved. SUS/SUE activities rely on the interpretation of an instrument generated signal in order to designate an asset. Signals are affected by soils type, humidity, contamination, and the proximity of other assets to the subject and locations with the effect of degrading the accuracy of the asset position. While it has been established that quality level D, C and B SUS/SUE studies render a return to investment ratio better than 10 to 1, there is no substitute to non-destructive excavation to accurately determine the location and depth of underground assets. Therefore, client shall perform its excavation with workmanlike methods and extreme care in the vicinity of survey marks, and assume any contingent, direct, and indirect liabilities as owner of the excavation.
