Scope of Services

Municipal Subdistrict, Northern Colorado Water Conservancy District

Windy Gap Firming Project Nutrient Mitigation –

Fraser Tertiary Denitrification Design

Background

The following describes the scope of work for providing engineering services for the design of tertiary

dentification facilities at the Upper Fraser Valley Wastewater Treatment Plant (Fraser) related to

nutrient mitigations for the Windy Gap Firming Project (WGFP).

Permits for the WGFP require the Municipal Subdistrict, Northern Colorado Water Conservancy District (MS-NCWCD) to mitigate additional nutrient load to the Three Lakes System. As such, Black & Veatch completed conceptual designs in June 2017 for nutrient mitigation at four wastewater plants (Fraser, Granby, Three Lakes WSD, and Winter Park) whose discharges are part of the WGFP flows. Each plant had an opportunity to partner with MS-NCWCD to construct the tertiary treatment facilities to assist them with current and future regulatory demands. Fraser, under regulatory demands for metals discharge compliance partnered with MS-NCWCD to construct a tertiary phosphorous and metals removal process that is currently under construction (2019 Metals and Phosphorous Project). A separate tertiary nitrogen treatment process was designated for future design, construction, and tie-in to the overall tertiary treatment system. Black & Veatch prepared a conceptual design for tertiary denitrification facility (9 November 2017). Black & Veatch’s conceptual design recommended construction of a tertiary denitrifying moving bed biological reactor (MBBR) process. Scope of Services Black & Veatch’s (Consultant’s) services will include preliminary design for the following anticipated project elements:

• Tertiary Denitrification MBBR Facility – includes a standalone building with three MBBR basins (two anoxic, one aerobic); MBBR treatment equipment (media, sieves, mixers); solids collection/ thickening process; solids pumping; process piping; electrical equipment for treatment equipment, pumping, and building systems. Flow to the MBBR facility will be delivered from the tertiary pump station under construction as part of the 2019 Metals and Phosphorous project. Equalized secondary effluent flow will be treated in the MBBR facility for nitrogen removal before being treated in the 2019 Metals and Phosphorous facility. MBBR biological solids will be separated from the flow prior to conveyance to the 2019 Metals and Phosphorous facility. Thickened solids will be conveyed to the solids storage basin in the 2019 Metals and Phosphorous facility.

• Chemical Storage and Feed Facilities – includes the chemical storage and feed equipment to be housed in the new chemical feed building currently under construction as part of the 2019 Metals and Phosphorous project. The space reserved for the new carbon storage and feed equipment will require buildout of the secondary containment for this chemical.

Windy Gap Firming Project pg. 2 Fraser Denitrification Design Exhibit A

• Blower Facilities – includes blower equipment, associated electrical equipment, and process for the MBBR aerobic process. The blower facilities will be located in the existing tertiary flocc/sed/filter building.

• Site Work – includes site grading to allow the MBBR facility to hydraulically fit with the 2019 Metals and Phosphorous facility; yard piping connections for all liquid, solids, and chemical flows between the MBBR facility and existing facilities.

The following documents will be provided to Black & Veatch as background documentation from Fraser:

• Wastewater Treatment Plant Expansion Drawings, 2002 (PDF and AutoCAD)

• Metals and Phosphorous Treatment Modifications Drawings, 2019 (PDF and AutoCAD) Task Series 100 – Project Management and Coordination Meetings Task 101 – Project Management

• Prepare a Project Management Plan (PMP) to identify the scope, schedule, budget, project team, and deliverables expected as part of this assignment.

• Establish a project Quality Assurance and Quality Control (QA/QC) program. Implement the QA/QC plan for all deliverables listed. Provide monthly project status reports including work completed, work anticipated, deliverables, budget/schedule status, and change tracking.

Task 102 – Project Meetings

• Conduct project progress/coordination meetings to coordinate the work. A total of three meetings are anticipated for the scope of work described in Attachment A.

Task Series 200 – Preliminary Design A preliminary design of the tertiary denitrification MBBR facilities will be developed under this task. This task will include:

• Geotechnical Services

• Survey Services

• Treatment process design

• Preliminary facilities design

• Cost estimating Task 201 – Geotechnical Services Consultant shall provide, through a subcontract with Lithos geotechnical engineering services. The services will include:

• Confirmation with Fraser for all boring locations prior to authorizing sub-consultant to

perform work.

• Initial geotechnical exploratory work, including four soil borings, penetration tests,

soundings, subsurface explorations, laboratory tests of soil samples that are required to

provide information for design, and other field and laboratory tests and analyses that are

required to provide design information. Rock coring is not included.

• An initial geotechnical report by a qualified geologist or geotechnical firm interpreting the

data collected from the exploratory work and laboratory testing and making assessments of

the site conditions and foundation recommendations that can be anticipated from this

initial exploratory work.

The deliverable for this task is and initial geotechnical report.

Task 202 – Survey Services Consultant shall gather recent existing survey information and drawings from Fraser. Any additional

survey to establish the location of existing surface features, the approximate location of buried

infrastructure, existing ground contours, and horizontal and vertical control for the entire site is being

deferred to final design. The surveying scope of work, accomplished using the services of a sub-

consultant, Rocky Mountain Surveyors, is to survey the locations of the geotechnical soil borings. All

contract documents will be based on the Highlands Ranch Datum that has been used historically at this

site.

The deliverable for this task is surveyed locations of the geotechnical soil borings.

Task 203 – MBBR Process Design Consultant shall conduct a process design of the tertiary denitrification MBBR system. Consultant and MS-NCWCD will agree on the effluent targets to be the basis for sizing prior to beginning process design. Additionally, Fraser will provide all available and relevant historical secondary/final effluent water quality data from the past 5 calendar years (2015-2019). Effluent parameters of interest include flow, temperature, pH, solids parameters (TSS, VSS), organics parameters (COD, BOD, sCOD, ffCOD), nitrogen parameters (NHX, NO2, NO3, TKN, TN), and effluent phosphorus species (Ortho-P, TP). Only then will the design proceed using these effluent targets with the historical effluent water quality data to determine process design criteria. Process design criteria include a process block diagram, the numbers of basins and their configuration/size, MBBR media properties, MBBR media fill fraction of basins, media retention sieve loading criteria, instrumentation requirements, supplemental carbon alternative selection, chemical dosage requirements, mixer requirements solids production rates, aeration demands, and the process requirements of any other major equipment deemed necessary. Consultant will coordinate with MBBR equipment suppliers to confirm the process design and to receive preliminary equipment quotes. Solids removal design will include clarifier configuration/size, clarifier overflow rate, and target solids concentration. The deliverable for this task will be a Process Design Technical Memorandum.
