SCOPE OF WORK
WASTEWATER AND SCADA SYSTEM MASTER PLAN
FOR THE CITY OF PEARLAND
The purpose of the overall Project is to prepare and update a Wastewater/SCADA master
plan for the City of Pearland (City) wastewater system. Some of the principal tasks in this
master plan include: develop a hydraulic model for the wastewater system; use the model
to identify existing capacity deficiencies and future capacity requirements for the
wastewater system; and develop a phased Capital Improvement Program, including
budget estimates, for implementing the required capacity improvements to the
wastewater system. The Project will also develop recommendations for immediate and
future needs for the wastewater system to implement a City-wide SCADA system.
SCOPE OF SERVICES
1. PROJECT 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 IA - 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 flow monitoring data 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 including:
· Existing wastewater modeling files, if any,
· 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 wastewater 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 collection lines, pump stations, wastewater
treatment plants (WWTPs), lift stations, 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 thc flow monitoring 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
collection system network 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 thc City's GIS manager
to plan for the City incorporation of any additional data generated by others at a later
date. Only the information available in accordance with the schedule of the project will
be incorporated into the master plan.
Deliverable: Database (Inventory of Facilities and Components) 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 wastewater 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 for operations and SCADA.
Deliverable: TM on preliminary assessment of facilities operation, SCADA and
recommendations for performance testing. A database will be provided for the
components required for modeling and for development of SCADA for 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 wastewater 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
(WWTP, and primary lift stations) 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 SCA_DA 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 (WWTPs and principal lift stations).
Deliverable: TM with recommendations for immediate requirements for the
implementation of a Central Hub SCADA system for principal facilities. It will include
prioritized schedule 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 -Wastewater Production Data
Task 3A - Land-use information integration
Montgomery Watson will compile ]and-use data provided by the City as necessary for
estimating existing and future wastewater flows 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 ETJ
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 wastewater 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 "polygon" 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 with the collection system to develop wastewater flows.
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 Wastewater Design Criteria
Montgomery Watson will review available flow monitoring and water use data to
develop factors for estimating base wastewater flow (BWF), groundwater infiltration
(GWI), rainfall-dependent infiltration/inflow (RDI/I), and peak dry and wet weather
flows. City provided flow monitoring data collected by the City from studies in the last 3
years on the major trunk sewers to the WWTPs, temporary meters placed in various areas
of the collection system, and treatment plant flow data will be used for this analysis.
Analysis of dry weather flows will focus on refining the unit flow factors for BWF and
per capita flows currently used by the City. Unit flow factors will be developed for each
of the consolidated land use categories (see Task 3A) to be used to develop collection
system wastewater flow projections. The development of unit flow factors and water
conservation impacts will be coordinated closely with City staff.
Recommendations will also be developed for appropriate design criteria (e.g., recurrence
frequency and type of design storm, anticipated RDI/I contributions from future
development, etc.) for evaluating collection system capacity requirements.
Data from the City's meters will be used to assess groundwater infiltration (GWI), both
on a seasonal basis as well as the short-term effects from rainfall events that may have an
impact on the WWTP system.
The results of the flow analyses and recommended design flow criteria will be
summarized in a Technical Memorandum for review by City staff. The recommended
criteria will be approved by the City's engineering department before proceeding with the
modeling work under subsequent tasks.
Deliverable: TM on flow evaluation and recommended design criteria.
Task 4 - Select and Update Existing Wastewater Model (Task 2)
Task 4A - Select Collection System Model and Develop Model Netw~)rk
The first step in this task will be the evaluation of hydraulic model options for the
wastewater system for the Project and for future use by City staff. Montgomery Watson
will identify up to three viable model options for evaluation and discussion with City
staff. The models will be reviewed with respect to compatibility with City data and
mapping formats; capability to provide the level of~hydraulic computation appropriate for
the City's system; user friendliness; flexibility for modeling future changes in system and
service area characteristics; costs for software and annual support; and availability of
technical support and future upgrades. The model options will be summarized in a
Technical Memorandum and discussed with City staff at an informal workshop. City
staff will make the final selection based on the information and recommendations
provided by Montgomery Watson. If the City selects to purchase the modeling software,
the license will be made available to Montgomery Watson for the project completion. If
the City selects not to purchase a model, Montgomery Watson will prepare the model on
an in-house model of its choice and will provide the City with the input/output files. The
cost element of this proposal is based on selection of a model from the recommended
Montgomery Watson's list. Otherwise Montgomery Watson will evaluate the conversion
of the data to the selected model and its impact on the proposal.
Deliverable: TM on model evaluation and recommendations.
Task 4B - Develop Model Network Files.
Montgomery Watson will build the required model network files using the City's existing
GIS files and additional data developed from information provided by the City. It is
assumed that the existing network graphics (AutoCAD, GIS and as-built files) can be
used by shifting and/or rubber-sheeting to match the City's current base map coordinate
system. New manhole numbers will be assigned using the City's current Cityworks
numbering system. These numbers will be assigned to the manholes in the existing
model database, as well as to any additional existing sewers added to the model. Data on
pipe diameters, lengths, rim, and invert elevations will be transferred from the existing
files to a database to be linked to the existing GIS system, and any facilities that are not
yet in digital form will be added based on information on the City's sewer maps and
available as-built drawings. It is anticipated that the model will include all 8~inch and
larger sewers.
In addition to the network data, a digital sewer subbasin map will be developed for the
model. It is anticipated that some digitizing of sewer subbasins may be necessary for this
effort. Additional sewer subbasins for new areas of development will be added to the
subbasin file. The subbasin map and the digital land use map created in Task 3A will be
processed using a polygon overlay process to quantify the land use categories in each
subbasin for use in developing flow inputs to the model.
Deliverable: Collection system model with existing facilities.
Task 4C - Verify and Validate Model.
Flow input files for the model will be developed using the land use data and design flow
criteria developed under previous tasks. A multi-step process will be used to verify and
validate the model. The first step is the verification of system connectivity and validation
for dry weather conditions. This step will confirm the unit flow factors and diurnal
curves used for estimating dry weather flows. The next step is the validation for wet
weather flow conditions. In this process, the model will be run for one or more actual
storm events for which flow monitoring data is available. Based on these model runs,
parameters in the model used to simulate RDIJI flows will be adjusted so that the model
simulated flows are in reasonable agreement with the monitored flows.
Deliverable: Validated collection model with existing system
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. Data should be
collected to allow validation for both dry and wet-weather periods. If the data available
from the City is insufficient, then a field monitoring program will be developed.
Requirements for location of equipment and duration for field monitoring for flow
quantity and flow depth testing will be identified for the wastewater collection system.
Deliverable: Field monitoring program
Task 5B - Collect Field Monitoring Data
MW will coordinate with City crews and personnel for the field monitoring efforts.
Monitoring for the wastewater system should include a period of two weeks without rain
as well as at least two rain event~ in order to have sufficient data to evaluate dry weather
profiles as well as RDI/I in the existing system. The time required to obtain the required
data will be vary depending upon weather conditions.
Task 6 - Master Planning of Future System
Develop Wastewater System Capacity Requirements
In this task, the hydraulic model will be used to determine collection capacity
requirements for peak dry and wet weather conditions. Model scenarios will be mn for
both existing and build-out conditions, as well as for the 5- and 10-year development
scenarios. The model runs will identify the capacity deficiencies in the existing system
and the required system capacity to serve current and future development.
The quantities of wastewater produce will be analYZed and the ability of the collection
system to provide transmission of the flows to the existing facilities or alternative
treatment locations. Treatment facilities will be evaluated for adequacy; treatment
capacity under existing flows and future flows; and pumping stations will be evaluated
for adequate capacity. The future systems will also be evaluated based on their ability to
maintain control of wet weather flows without overflows. All of these analyses will be
based on the established system criteria.
Deliverable: TM with wastewater allocation and maps with model runs for 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 plan 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 location of potential wastewater treatment facilities will be evaluated to minimize
cost of transmission to the facilities and for the number of required facilities. A
recommendation will be made for the a cost-effective solution to develop and provide
these treatment 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
permitting 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 wastewater 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
wastewater 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 future facilities (lift stations)
will be provided. The CIP will recomend new facilities for providing services to the
growth 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 integration to the main control system.
Montgomery Watson will provide the City with standard SCADA design parameters,
logic flow diagrams and operational procedures for future lift stations. 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 implementations for lift stations.
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 address new wastewater flow characteristics) 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 models but
does not cover the engineering of collection systems. The service provided under this task
would entail on-site consultation and advice from a MW engineer experienced in systems
design.
Task 1112 - 12onduct Refresher Training
Additional training in the use of the modeling software will be provided to the City after
the final report for the project is submitted to the City. 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 montl~ 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 - Coordination with TWDB and Other Agencies
Four meetings will be scheduled with TWDB to cover the elements of work and get
approval of the presented information and master plan report. This plan is an integral part
of the development for the City of Pearland.
Task 12C - 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.
