Phelan Piñon Hills Community Services DistrictWater System Hydraulic Model Update

This scope of work (SOW) provides a detailed description of the tasks and deliverables required to update the District’s water hydraulic model. The District updated and calibrated the water hydraulic model in 2010. The District requested updating the hydraulic model to enable their in-house staff to utilize this tool and plan for growth and optimize their water system operations.

The District’s goals in updating the hydraulic model are to:

1. Identify and resolve known seasonal low water pressures within their pressure zones 2. Identify the best location for additional groundwater well sources 3. Identify the most suitable location for additional water storage, if deemed needed

The District maintains and updates their water system Geographic Information System (GIS) database in-house. The District utilizes hand-held GPS devices to obtain field information to map their facilities. IEC recommends that the water system network be built by importing the most current GIS database files instead of attempting to update the old system network. This approach will expedite updating the water system network to obtain the minimum degree of completeness. After IEC collects and reviews the District’s current data files, IEC will provide a list of recommendations on data clean-up to expedite model build. Once corrected files are provided to IEC and the model is being built, the District will need to avoid making any updates to their GIS database to avoid synchronization errors.

Task 1 – Project Management and AdministrationIEC will hold a kick-off meeting with the District staff to establish the goals, needs, and desires of the model build, confirm project objectives, discuss approach and criteria, establish departmental contacts and lines of communication, and discuss data availability and accuracy for model input. IEC recommends using InfoWater as the modelling software and will provide the District with a complete description during the kick-off meeting to obtain input, address questions, and gain approval prior to building the model.

IEC will submit to District a Request for Information (RFI) in advance of this meeting. IEC will prepare a meeting agenda and submit to the District prior to the meeting. IEC will prepare meeting minutes and submit to the District following the kick-off meeting.

Our scope includes three (3) progress meetings at key milestones during the Project. Meetings will be held to resolve data issues, understand system operations, and items needing resolution during the Project. IEC will provide project status updates to the District weekly or monthly, depending on Project activity.

Task 2 – Hydraulic Model BuildData Collection & ReviewA data/document inventory will be maintained to log the data/documents received from the District, the date received, and if the data needs to be returned to the District. This inventory will be updated as new information is received. The log will be submitted along with the project status updates.

Build Model from GIS GeodatabaseThe GIS Gateway function will be used to import the District’s GIS layers of pipes, system valves, control valves, pumps, tanks, and wells. Table 1, on the following page, shows facility information typically available in GIS format used to build a water system model.

IEC will use existing elevation information provided by the District. It’s assumed that elevation and coordinate data for above grade water features like tanks, and pumps, were obtained by the District utilizing hand-held GPS devices. Other District-provided elevation sources, such as USGS will be utilized, as necessary.

Model Facility ID numbers will be changed to correspond to District standards.

Assumptions: GIS data provided by the District will have layers for facilities like Pipe, Pump, Tanks, Pressure Tanks, System Valves, Control Valves, and Wells to create a complete water system network. It is anticipated that the GIS, at a minimum, will have a complete record of pipe diameters, zone boundary valves (closed, control, check) identified, and a verified pressure zone boundary layer for reference. IEC will perform checks in the model for pipe connectivity, disconnected nodes, and parallel pipes as a measure of quality control. GIS data errors found outside IEC’s initial checks will be discussed with the District prior to project continuation. Once District makes corrections, a final GIS import for network build will be done.

Where relevant, previous model data will be referenced to get the most accurate data representing the system. The results of model checks will be provided to the District via technical memo.

Demand AllocationInfoWater’s Demand Allocator will be used to assign demand from meters to the model network via “nearest pipes” method. Water demands will be adjusted to include non-revenue water in the model.

Assumptions: Meter billing records are assumed to have correct customer categories, addresses which are geo-referenced, and can be “joined” and matched one-to-one to the GIS meter layer. If inconsistencies are found during demand allocation, IEC will discuss with District prior to project continuation. The demand allocation process will be documented via technical memo.

Diurnal Pattern & Facility Curves CreationUpon discussion with District, and depending on available data, Diurnal Curves for a maximum of three (3) zones will be created. Otherwise, a system-wide diurnal curve shall be provided.

Pump curves and valve curves, if available, will be added into the model. Where information is unavailable, IEC will discuss the recommended approach with the District prior to project continuation. The diurnal pattern(s) will be provided to the District via technical memo.

Build Scenarios, Selection Sets, Data Sets & Model SetupIEC will develop Average Day and Max Day Data Sets in the Model. For ease of navigation within the modeling environment, Selection Sets and Query Sets will be created upon discussion with District. This task will also include other general model setup activities.

Add Boundary Conditions & Operational ControlsAs part of the data collection and review process, IEC will compile the existing boundary conditions and operational controls and from the old hydraulic model and Master Plan for District review. IEC will collaborate with District staff to determine whether changes should be made prior to hydraulic model input.

Assumptions: District SCADA will be the primary source of operational control data. If there are manual or local changes that override SCADA controls on a daily or weekly basis, IEC will require a log sheet indicating those changes (e.g. facility, control setting, time) on chosen model calibration days. The table of boundary condition changes will be submitted to the District via a technical memo.

Task 3 – Model Calibration and VerificationEPS ValidationIEC will collaborate with the District to establish one (1) extended period simulation (EPS) scenario that will provide the most value as a validation scenario. IEC will collaborate with the District to determine the data sources available for verification. Upon preliminary comparison of model and field data, a plan shall be submitted to identify and prioritize adjustments to the model to enhance verification. The EPS verification results will be submitted to the District via a technical memo.

Fire-Flow ValidationIEC will work with the District to identify one location per zone for fire flow testing. Upon identification of the locations, IEC will develop a fire flow testing plan for review and comment by the District. Each location will be tested by flowing one (1) hydrant and recording static and residual pressures at two (2) proximate hydrants. The plan will account for the safe discharge of hydrant water at all locations.

Assumption: District will perform all field work related to this task.

Upon collection of suitable data from the fire flow tests, this field data will be compared to model simulation data. Hydrant nodes used in the comparison, both as flowing and as residual hydrants, will be identified in the model such that they can be queried for easy identification and comparison. Because the model is starting from a calibrated state, should adjustments (e.g. C-factors) be required to dial-in validation, IEC will discuss this with the District to focus on validation parameters that will improve validation while most accurately reflecting field conditions that have changed. The fire flow testing plan shall be submitted to the District along with the final calibration tables and figures via a technical memo.

SCOPE OF WORK

Task 4 – Prepare Executive Summary and Final DeliverablesIEC will compile the technical memorandums prepared for each milestone described in the tasks above and incorporate the District’s input, comments, and make one set of revisions. The technical memorandums will be finalized and the executive summary along with the final technical memos will be provided to the District in PDF format.

One set of District comments will be addressed and incorporated into the final deliverable. The final deliverable will be provided via PDF format and two (2) hard copies. Electronic data will be provided on a removable storage drive and will include project-related information.

Task 5 – Training and Technical SupportAfter the final hydraulic model validation is complete, IEC will organize and conduct a four (4) hour training session at the District. IEC will provide technical manuals and training material.
