SCOPE OF WORK
WATER AND SCADA SYSTEM MASTER PLAN
FOR THE CITY OF PEARLAND
The purpose of the overall Project is to prepare and update a Water/SCADA master plan
for the City of Pearland (City) water system. Some of the principal tasks in this master
plan include: develop a hydraulic model for the water distribution system; use the model
to identify existing capacity deficiencies and future capacity requirements for the water
system; evaluate different water sources to meet future demands and develop a phased
Capital Improvement Program, including budget estimates, for implementing the required
capacity improvements to the water system. The Project will also develop
recommendations,for immediate and future needs for the water system to implement a
City-wide SCADA system.
SCOPE OF SERVICES
1. PRO,]ECT DESCRIPTION
The Services to be performed by ENGINEER shall be as follows:
The tasks included in Montgomery Watson's Scope of Services for this Project are
described below. Where applicable, deliverables are indicated after each task description.
Technical memoranda (TMs) will be prepared in draft form for review by City staff.
Final TMs, including revisions to address City's comments and/or incorporate additional
information, will be completed as part of preparation of the Master Plan Report.
Task 1 - Information Gathering
Task lA - Review Existing Reports and Documents
Montgomery Watson will compile and review information relevant to the project
provided by the City, including land use planning documents; the City's existing
infrastructure mapping; existing master plans; as-builts and construction documents.
Additional information to be evaluated includes water production and consumption
records and information available in other pertinent reports and/or studies available from
the staff. After review of the documents, key items as well as the limitations of the data
will be discussed with City staff.
A list of the information to be submitted or made available by Pearland in order to start
this project includes:
· Existing water modeling files,
· Infrastructure maps,
· GIS data for land-use, zoning, planning and tax maps, data libraries for GIS tables,
· Previous master plan documents,
· As-Builts and construction plans for wate~ infrastructure, and
· Design standards and operations.
Task lB - Integration of Existing Information and Documents into Project
Databases
Montgomery Watson will collect and integrate information on the existing systems in
order to update the databases for the needs of the master plan. Information to be
evaluated includes maps and construction documents of the existing systems and data on
all existing physical facilities including pipelines, pump stations, storage tanks, wells,
connections to other systems, and SCADA. Information on population distribution as
well as projections for the study years will be incorporated into the mapping system for
later integration with the demand information. The collected data will be reviewed and
supplemented with information gathered from discussions with the City's engineering
and Public Works staff. The information required for use in the master planning effort
will be stored into databases and maps within a GIS, to allow easy linking and integration
to further modeling and mapping which will be conducted for this and any future
projects.
Montgomery Watson will coordinate with the City in the preparation of table structures
and forms for the integration of information on survey and GPS work from collection of
distribution system networks being currently performed in Pearland by others. The data
gathered by others will be available in accordance with the schedule of the project as per
preliminary meeting between all entities involved in these efforts. Montgomery Watson
will prepare the system database structures in coordination with the City's GIS manager
to plan for the City incorporation of any additional data generated by others at a later
date. 0nly the information available in accordance with the schedule of the project will
be incorporated into the master plan.
Deliverable: Database for all of the components of the information in land use and
facilities as needed for development of this master plan.
Task lC - Interview and Field Investigation of Facilities
Montgomery Watson will complete a preliminary assessment of facilities in the field and
their operations. The analysis will be based on interviews with field and engineering
personnel. A field visit to each of the existing water facilities will be completed in order
to obtain and verify facilities information compiled and necessary for the evaluation of
their operations and requirements for SCADA implementation. Data will only be
collected for equipment which is readily accessible. Collection of field information does
not include pulling or testing of pumps in the system.
Montgomery Watson will prepare a database in coordination with the City's GIS team for
the facilities information compiled which is necessary for establishing parameters for
modeling and SCADA implementation. A TM will be prepared with the deficiencies and
problems encountered during the field assessment.
Deliverable: TM on preliminary assessment of facilities operation and recommendations
for performance testing. A database will be provided for the components required for
modeling and development of SCADA of the facilities.
Task 2 - Immediate SCADA Recommendations for Principal Facilities
Montgomery Watson will complete a TM for the definition of the SCADA system
approach for principal water facilities and its integration into a system-wide SCADA to
be planned in a subsequent task. The TM will include recommendations for SCADA
equipment and codification of programs for the facilities selected as principal (Water
Plants) and an approach for incorporation these facilities into a central SCADA control
program. The data gathered in the field evaluation as well as the information from the
City's operations staff will be used to prepare this TM.
Montgomery Watson will prepare a cost estimate for the implementation of the upgrade
and placement of the SCADA and its associated improvements for the principal facilities.
This memorandum will focus in the definition of the central hub for SCADA and its
principal on-line facilities (water plants).
Deliverable: TM with recommendations for immediate requirements for the
implementation of a Central Hub SCADA system for principal facilities. It will include
prioritized schedules and budgetary estimates for the hardware, software for upgrade
requirements of the principal facilities to be implemented in the next fiscal year. A cost
analysis of the implementation will be presented per element of the program for
budgeting purposes.
Task 3 - Water Demand Data
Task 3A - Land-use information integration
Montgomery Watson will compile land-use data provided by the City as necessary for
estimating existing and future water demands in the system. These tasks will be
coordinated with the Planning department of the City and consultants that are working on
this information.
A consolidated land-use map prepared by the City in digital form will be used. The map
incorporates the land use from all relevant planning documents, including the City's ETS
and future planning zones. In using the digital map, it is assumed that the City's existing
GI$ land use maps can be used for this purpose with minimal changes. These existing
digital files will be "rubber-sheeted" to match the base map coordinate system currently
used by the City's consultant in the survey and GPS work.
The land use categories shown on the various planning maps will be consolidated into a
set of common categories that can be used for water system planning. After review of the
planning documents, Montgomery Watson will present a set of categories for review by
City staff for the Master Plan update. The final categories will be approved by the City.
Each land use "polygoff' shown on the digital map will be tagged with the appropriate
land use category that can be used for compiling the data through a GIS polygon overlay
process to develop water demands.
Discussions will be held with the City planning staff to identify the expected timing of
development for different portions of the service area, and separate layers will be
developed to display 5-year, 10-year, and build-out land-use. This information will be
used to develop the phased capital improvement program in subsequent tasks of the
Project.
Deliverable: Consolidated digital land use map in GIS format showing existing, 5~ and
10-year development, and build-out land uses in the City's service area.
Task 3B - Develop Water Design Criteria
System criteria will be defined for use in evaluating both the existing and future systems.
Criteria of importance include maximum and minimum acceptable pressures, maximum
acceptable pipeline velocities and headlosses, minimum acceptable chloramine residual,
emergency storage volumes, emergency power requirements, and fire fighting
capabilities. Fire fighting requirements will be identified as per the Fire Marshall and any
additional City or State requirements.
Diurnal fluctuations are the time-varying patterns of demand experienced by water users.
The summation of all time-varying demands of all users within a particular area gives the
total system time-varying demand for that area. Conversely, the hour-by-hour system
demand experienced, as determined by development of a mass-balance of all facilities
supplying water to or withdrawing water from the system, depicts the total hourly
variation of consumer demands, assuming that there is no unaccounted-for water. As long
as unaccounted for water is a small percentage of the total, it is typically accounted for by
modeling to match water production data instead of consumption data. This provides
conservative hydraulic results and assumes that all unaccounted-for water is spread
equally throughout the system. Diurnal curves for each land-use type service area will be
developed for an hourly basis if sufficient data is available. The data received with
historical information on the long-term (will need to be for last five years at a minimum)
metering pattems will further help determine the definition of diurnal patterns for the
different user types. The principal criteria to be determined are average day, maximum
day, and peak hour. These scenarios will be integrated with the developed diurnal curves
in order to verify the mass-balance calculations and further integration into the model for
Extended Period Simulation calibration later in the project.
Deliverable: TM on flow evaluation and recommended design criteria.
Task 3C - Develop Water Blending Potentials Problems from City of Houston
Connections.
Evaluate the impact on water quality of blending surface water taken from City of
Houston and groundwater from wells in the Pearland system. The evaluation will
consider the two existing connections with the City of Houston plus one additional future
connection at one of two locations in Pearland and current and future projected
groundwater plants in Pearland. Potential solutions to any projected water quality
problems will be evaluated including segregation of portions of the City of Pearland
system and conversion of the Pearland system disinfectant from free chlorine to
chloramines. Recommendations will be provided for resolving any identified potential
problems including system modifications, schedule and capital costs.
Deliverable: TM on blending and recommendations for City of Houston and City of
Pearland Connections.
Task 4 - Update Existing Water Model
Task 4A - Validate Existing Water Model System
The current WaterCAD model will be converted to H2ONET. The conversion will
address apparent model errors but does not include field confirmation of such information
as pipe connectivity, diameter, and material. It is important that the existing model be
verified and corrected as necessary since subsequent model calibration and system
evaluation tasks depend on having a complete and accurate network model as the starting
point. This proposed task would verify the attributes of pipes currently in the model as
well as add additional existing pipes to the model based on information gathered in Task
1 from the City. All pipe material information obtained shall be incorporated directly into
the computer model for easy future reference and use. This task also includes adding
piping to accurately reflect pump station header piping, storage tank headers, and other
related piping that is currently represented in the model in simplified form. Descriptions
of operational parameters, in both text and logic formats, will be provided for the entire
system and for each controlled facility. Operational parameters include valve settings and
controls for pumps, tank levels, and plants. This task will also include incorporating
pump characteristics as collected in Task 1. The diameter, bottom, minimum, and
maximum water elevations for each tank will be included as available. In addition,
elevated tanks with non-cylindrical shapes will have their depth versus volume curve
input for accurate modeling. Altitude valves will be modeled where appropriate, as well
as tank piping that allows for water fill and withdrawal from the tank.
Deliverable: H2ONET modeling Software and Model files with existing facilities.
Task 4B - Validate Existing Model Water Demands
The allocation of demands throughout the existing system model is critical to the accurate
representation of system hydraulics. If demands are modeled differently than where they
are actually occurring, then the model predictions will not accurately reflect actual
conditions. This task includes allocating the annual average water billed during calendar
year. Demands will be allocated using billing records, updated population allocation
zoning information, or other suitable method depending on availability of suitable data
from the City. Water produced (pumped) will be compared with water billed to determine
the "unaccounted-for" water loss. This water loss may be due to un-metered construction
water, illicit water taps, fire hydrant tests and flushing programs, and other unaccounted-
for water types.
Deliverable: TM with water loss and distribution of water demands.
Task 4C - Evaluate Adequacy of Existing System for Pressure
The existing system will be evaluated using the updated model for its ability to meet the
system criteria defined in Task 3C. Analyses will be conducted to determine the
adequacy of the existing system for peaking and emergency purposes; ability of storage
tanks to replenish on a daily basis; and adequacy of pipelines to convey sufficient water
at acceptable pressures to City customers.
Deliverable: Validated H2ONET model for existing system w/pressure mapping
Task 5 - Perform Field Monitoring (Optional)
If the existing information from previous monitoring records is not sufficient or the
model can not be validated with the existing data, collection of additional monitoring data
may be required. If additional data is required, this optional work task may be
authorized.
Task 5A - Develop Field Testing Program
Data utilized to validate the model must be sufficient for this purpose. If the data
available from the City is insufficient, then a field monitoring program will be developed.
Requirements for location of equipment and duration will be identified in the distribution
system for collection of field monitoring for flow, pressure and tank volumes (ground and
elevated) for the water model.
Deliverable: Field monitoring program
Task 5B - Collect Field Monitoring Data
Field monitoring data for the water model system validation are typically gathered during
the summer, and data is most beneficial if gathered at flows near maximum day
conditions. MW will coordinate with City crews and personnel for the field monitoring
efforts. It is anticipated that between 3 to 5 days of flow monitoring data on the water
system will be necessary to provide the data necessary to successfully validate the water
hydraulic model.
Task 6 - Master Planning of Future System
Develop Water Demand Projections and Water System Requirements
This task involves the determination of water demands anticipated for future systems in
build-out conditions, as well as for the 5- and 10-year development scenarios.
Information developed in previous tasks will be used to evaluate future production and
consumption to determine average day, minimum day, maximum day, and peak hour
demands on a system-wide basis. Future demands will be determined based on all
available information from the City Planning Department, the Texas Water Development
Board, and any additional specific development information available. Projections will be
based on normal annual scenarios.
The future system projected total demands will be allocated throughout the future system
model based on planning information and on specific large water user information. Water
use patterns identified for the existing system will be evaluated and confirmed for
applicable use for future systems. This information will be utilized in the allocation of
water demands for the future system.
The quantities of water available to meet the futura demands will be analyzed and the
ability of the distribution system to provide flows at required pressures during peak hour
conditions and during simultaneous maximum day and fire events will be evaluated.
Supply sources will be evaluated for adequacy; storage tanks will be evaluated for
adequate capacity under operational, emergency, and fire fighting; and pumping stations
will be evaluated for adequate capacity. The future systems will also be evaluated based
on their ability to maintain a minimum pressure. All of these analyses will be based on
the established system criteria. The results of the model runs will be displayed on maps
for discussion with City staff.
Deliverable: TM for demand allocation and maps for pressure distribution for each
future development scenarios.
Task 7 - Capital Improvement Program
Task 7A - Develop Basis of Budget Level Cost Estimates
Representative unit costs for each type of facility will be developed from recent City
projects and cost data compiled by Montgomery Watson based on projects in similar
areas. In addition, costs for other improvements will be developed as necessary based on
system recommendations. These cost will be utilized in the CIP to develop the estimated
cost for each phase of the Program.
Deliverable: Unit cost rate per facility tables.
Task 7B - Develop Capital Improvement Program
This task will develop specific capital improvement projects required to address the
existing system deficiencies and future capacity requirements identified in Task 6. In
developing proposed capital improvement projects, Montgomery Watson will review and
build upon the previous master plans for the City. A proposed phasing plan for the
Capital Improvement Program (CIP) will be developed based upon when facilities are
projected to be required to relieve existing system capacity deficiencies or provide
service for anticipated new development. The potential impact of water conservation on
the sizing and/or timing of CIP projects will also be addressed.
The potential water supply alternatives for the City will be evaluated to determine the
necessary projects to integrate the potential alternatives. The scenarios to be evaluated
are; raw water from Gulf Coast Water Authority (GWCA), treated water from GWCA,
treated water from the City of Houston and a combination of receiving treated water from
both utilities. A recommendation will be made for a cost effective solution to develop and
provide these supply alternatives to the different users in the City.
Projects recommended for construction in the first five years of the CIP, or major future
projects will be presented with proposed alignments. From projects to be constructed in
the first 5-year phase, a list of high priority capital projects to be subject to more detailed
analysis will be selected jointly by MONTGOMERY WATSON and City staff. For these
projects, potential alternative alignments will be investigated, available utility maps will
be obtained to identify any significant potential utility conflicts ("fatal flaws"), and key
perrrdtting and easement requirements will be identified. Recommended alignments will
be selected based on cost, constructability, potential environmental impact, and other key
considerations.
Budget level cost estimates will be prepared for each recommended capital improvement
project. Costs will be based on unit cost data developed in Task 7A.
Deliverable: Proposed CIP schedule, CIP Project Summary sheets, and costs;
conceptual plan for highest priority capital improvement projects.
Task 8 - SCADA Master Plan and Standards
Task 8A - SCADA Planning and CIP.
Montgomery Watson will prepare a draft plan for the SCADA requirements associated
with the new and existing facilities required under the water master plan. The plan will
include definition of the logic of installation and control systems for the preparation of
the system into an automated control process, The cost associated with coding and
implementing SCADA in the principal facilities was presented under Task 2. This task
will extend that planning to the existing facilities and the new ones defined by the water
master plan. This system does not include the actual code and implementation of the plan.
Deliverable: Draft and final SCADA master plan update reports
Task 8B - SCADA Standards of Design and Implementation.
A standardized approach for SCADA implementation for its futura facilities (tanks, pump
stations, and elevated tanks) will be provided. The CIP will recomend new facilities for
providing services to new demand areas in Pearland. In addition to the logic and control
process to be developed for the central SCADA control unit, new facilities should be
designed and constructed with a compatible control and communications to allow
ihtegration to the main control system.
Montgomery Watson will provide the City with standard SCADA design parameters,
logic flow diagrams and operational procedures for future water plants, pump stations
and well facilities. These standards will have basic conceptual design approach as well as
control and operations outline specifications for PLCs and equipment.
Deliverable: Standard design documents for SCADA implememations for pump
stations, elevated tanks, and ground storage tanks.
Task 9 - Prepare Master Plan Update Report.
A draft Master Plan Update Report will be prepared to summarize and present the results
and recommendations of the study. It is anticipated that report sections will correspond
to the tasks in the Scope of Services, and the TMs will form the basis for relevant report
sections as well as be included in the report appendix. Report graphics will utilize the
digital maps developed for the project. Five (5) copies of the draft report will be
prepared for review by City staff. City's comments on the draft report will be
incorporated into the Final Master Plan Update Report. Ten (10) copies of the Final
Master Plan Report will be provided.
Deliverable: Draft and final master plan update reports
Task 10 - Implementation of Information System and Digital Model
Montgomery Watson will provide the City with the information gathered under this
project and developed by this master plan on a format which is compatible and fully
integrated with the City's GIS. The current GIS system for the City operates under an
ArcView platform. A meeting will be held with the City and its GIS consultant at the
beginning of the project to define the logic plan for the applications to be developed for
the master plan for compatibility with the City's GIS.
The scripts written for modeling will be provided to the City for integration into their
current GIS platform. The interface between the users and the GIS data is under
development (GISMO) by the City's GIS consultant. Montgomery Watson will
coordinate with the consultant during the project in providing sample data for testing and
evaluation of the upgrades that the City will need to implement to allow incorporation of
the master plan data into their system. The final delivery of data will be coordinated with
the City's consultant for incorporation to their system. Any support for incorporation of
the data into the City's GIS or for associated training is not included as part of this scope
of work but can be provided to the City under a separate task if desired.
The model software selected by the City will be integrated by using common databases
with the City's GIS. A meeting between Montgomery Watson and the City's GIS
consultant at the beginning of the modeling task will take place to prepare a TM with the
database libraries for the modeling information so the City's GIS can be prepared by their
consultant to received all of the modeling information developed for the master planning
effort.
Deliverable: TM with data libraries and routines used for the integration of the master
plan information and the modeling systems to the City's GIS program.
Task 11 - Training and Support
Task llA - Model Training.
Training will be provided for City staff on the use of the model developed, and the
methods used to modify model inputs to analyze any anticipated changes or interim year
evaluations. This training will include instruction in how to use the computer model,
methodologies utilized in setting up and configuring the City's existing and future system
models, and hands-on modeling training for City staff. Three days of training for the
model has been included. Handouts for the trainings will also be provided.
Task liB - Additional Engineering Assistance
A limited amount of engineering assistance (forty hours total) in the application of the
models will be provided to City staff for a period after the initial training. The purpose is
to assist City staff in applying the model (for example, to analyze system improvements
needed to incorporate a new water source) so that they can be effective and efficient in
finding solutions to problems. This engineering assistance is separate from the staff
training. The training in Task 1 lA addresses the details of how to use the model but does
not cover the engineering of distribution system. The service provided under this task
would entail on-site consultation and advice from a MW engineer experienced in systems
design.
Task 1 lC - Conduct Refresher Training
Additional training in the use of the modeling software will be provided to the City after
submittal of the draft final report. This training will be a two-day total refresher program
with the City staff. The purpose of this follow-up training is to refresh City staff on
model use and to present additional model techniques that may be useful.
Task 12 - Project Management and Quality Control
Task 12A - Project Management.
Monthly progress meetings will be held with City staff to review project status and
discuss project issues. Montgomery Watson will prepare and distribute minutes of each
meeting. Montgomery Watson's project manager will monitor project budget, labor hours
expended, and schedule on a weekly basis throughout the project, and prepare monthly
status reports describing the work completed during the previous month and summarizing
the status of the project. Invoices will be prepared monthly for submittal to the City. The
budget for this subtask is based on attendance at monthly progress meetings and a project
duration of up to nine months.
Deliverables: Meeting minutes; monthly status reports.
Task 12B - Quality Control.
Quality control will include checking of data and calculations, as well as review of
proposed criteria and recommendations by a committee composed of Montgomery
Watson senior personnel in the area of master planning and design who are not involved
in the day-to-day work on the project. This "criteria committee" will meet formally at
least twice during the Project, and will also review all key deliverables including TMs
and the draft Master Plan Update report.
