I. INTRODUCTION

The City of Palo Alto (City) owns and operates a Regional Water Quality Control Plant (RWQCP) which treats wastewater from six communities. The RWQCP has a permitted dry weather capacity of 39 million gallons per day (MGD), annual average treated flow of 1 9 MGD, and a wet weather capacity of 80 MGD.

The RWQCP produces approximately 230 million gallons of tertiary -treated recycled water annually with much of the demand occurring May - August. The City’s objective for this Advanced Water Purification System (AWPS) project is reducing the total dissolved solids (TDS) concentration in recycled water from about 810 mg/L to 450 ± 50 mg/L. In 2019, the recycled water produced at the RWQCP had an average concentration of 810 mg/L TDS.

This Scope of Services is for the detailed design of an AWPS located at the RWQCP to initially provide 1.125 MGD of permeate, with provisions for future expansion to produce 2.25 MGD of permeate in a subsequent construction phase. The AWPS will be designed to consist of Ultrafiltration (UF) or Microfiltration (MF) followed by Reverse Osmosis (RO) treatment processes as well as all chemical storage / feed systems and ancillary components as defined herein. The AWPS will be designed to be fed disinfected recycled water from the RWQCP for initial construction. In the future expansion to 2.25 MGD, it is anticipa ted that the AWPS will be fed disinfected final effluent. The produced permeate from the AWPS will be blended at an appropriate ratio with the existing tertiary -treated recycled water in order to achieve an instantaneous TDS concentration of 450 ± 50 mg/L. RO concentrate will be blended with RWQCP final effluent prior to discharge through the RWQCP’s outfall pipeline. In addition, the AWPS design will include provisions to also serve as a test bed (i.e. pilot skid) to conduct research and operational studies that would inform future efforts to develop water reuse in Santa Clara County.

The AWPS Facility will be owned by the City and operated and maintained by the City’s RWQCP staff. The AWPS Facility will be funded by the City, the City of Mountain View (Mountain View) and the Santa Clara Valley Water District (Valley Water) (Mountain View and Valley Water are referred to together as the “Agency Partners”). It is the City’s goal that all public utility connections to the AWPS Facility will be metered separately and can be isolated physically from the core infrastructure of the RWCQP. exis ting infrastructure. A new electrical service will be established for the AWPS with the City’s Electrical Utility that is sized for the initial 1.125 MGD project, and the expansion to 2.25 MGD. Flexibility to add an in -pipe type UV reactor for disinfection will be included in the electrical loads and site plan.

The City, as the lead agency, with participation by Mountain View, Valley Water, and the project Consultant Black & Veatch, has prepared this Scope of Services that includes all necessary tasks Docusign Envelope ID: 95F7AAB9-B304-4056-8493-45AA9A046B20 DocuSign Envelope ID: C433F245-C478-46FF-98D9-0F923BDBB478

Docusign Envelope ID: 95F7AAB9-B304-4056-8493-45AA9A046B20

Contract No. C21178333
8 CONSULTANT shall establish the finished floor elevation of the AWPS at 14.0-ft above sea level.

CONSULTANT will verify that this is above the FEMA Base Flood Zone Elevation for this site and will prepare equipment installations above the flood zone accordingly. CONSULTANT shall incorporate in the design any additional pertinent requirements from the City of Palo Alto Sea Level Rise Policy.

Incorporating the City Sea Level Rise policy will require the finished floor elevation to be approximately 14.0 feet NAVD88.

The design shall consider the turning radius for chemical delivery trucks from within the RWQCP to the AWPS Chemical Storage Area. CONSULTANT shall include a pavement restoration design for those RWQCP areas impacted by construction. CONSULTANT shall inclu de in the design repaving around existing facilities at the north end of plant impacted by excavation and construction.

CONSULTANT shall route all stormwater from the site to the RWQCP’s headworks.

1.2 Process Mechanical Design

• Reverse Osmosis (R.O.) Cleaning system
• Blending station to produce enhanced recycled water
• Pilot test bed area & sampling points throughout the process. • Motor Control Center design
• Fire Protection System design for the building(s)
• Medium Voltage and Low Voltage Power Distribution system design • Instrumentation and Control system design
• Access platforms and stairs for accessing equipment
• Other required ancillary systems identified in the City’s Preliminary Design Report

CONSULTANT shall confirm the RO permeate storage requirement for the initial 1.125 MGD and for the future AWPS expansion to 2.25 MGD capacity and coordinate with the City for selection of the tank material.

CONSULTANT shall evaluate needed blending facilities for reverse osmosis permeate and the existing tertiary-treated recycled water currently produced at the RWQCP under initial and future expansion conditions. CONSULTANT shall explore alternatives for blending facilities including those specified in the Preliminary Design Report as well as other possible locations and try to avoid the use of underground areas that are highly congested with existing utilities.

CONSULTANT shall include in its evaluation all facilities (including additional storage and in -situ Docusign Envelope ID: 95F7AAB9-B304-4056-8493-45AA9A046B20

Contract No. C21178333
9 automated instrumentation) needed to blend the purified water with the existing tertiary -treated recycled water. The AWPS PDR blend ratio is based on a 1:1 blending ratio between these sources; however, in reality this will not work, and the City needs the ability to vary the blending ratio to meet a much greater turndown ratio. This is especially true in the wet weather season when recycled water usage typically drops. This critical design aspect needs CONSULTANT to review the existing controls of the Recycled Water Reclamation Plant Feed Pumps and hypochlorite dosage control strategy as it relates to incorporation into the new blending strategy. Consideration should be given to retrofit the pumps’ constant speed motors with inverter duty motors and VFD controls, and modification of the hypochlorite injection control and feedback loop. CO NSULTANT shall provide details on automated valves, flow meters, controllers, and other equipment to provide the City flexibility to operate and increase or decrease the blending ratios depending on production and demand of enhanced recycled water. CONSULT ANT shall also provide details on the operational aspects of blending and blending percentages, such as rotating equipment trains, returning permeate to the head of the system, etc., such to minimize enhanced recycled water production during those periods of low demand.

CONSULTANT shall design blending facilities for RO concentrate into the RWQCP outfall line. The current RWQCP NPDES Permit (Order R2-2019-0015) authorizes blending up to

0.2 MGD of reverse osmosis concentrate from the planned AWPS with fully treated effluent prior to discharge, thus slightly increasing the concentration of the discharge.

CONSULTANT shall design a pipe stub out and isolation valve to the plant effluent line for a future pipeline and pump station that will convey treated effluent to a future regional recycled water facility, to be located within the City of Palo Alto and owned by Valley Water. The tie-in point might consist of a valve vault for connections to a pump station, which would convey the water to the future facilities. Space should be allocated to locate a future pump station in close proximity to the piping tie-in point.

1.3 Structural Design

CONSULTANT shall provide a structural design that is in accordance with all jurisdictional requirements including the 2019 California Building Code. Seismic design requirements shall apply to the building / canopy structure as well as non-structural components. CONSULTANT shall include field verification of existing infrastructure for design of proposed structural improvements under this project.

CONSULTANT shall design the AWPS to be constructed on a concrete slab with canopies over AWPS filter and membrane equipment.

CONSULTANT shall conduct a geotechnical study at the project site to properly characterize the soils and groundwater conditions, and develop recommendations including foundation design for the AWPS, permeate storage tank and ancillary facilities. CONSULTAN T should anticipate that a pile supported slab is required. CONSULTANT shall evaluate if a pile supported slab foundation is the best option or provide a more suitable solution provided the detailed geotechnical study. For more details about the preliminary foundation design refer to the Geotechnical Desk Study – Advanced Docusign Envelope ID: 95F7AAB9-B304-4056-8493-45AA9A046B20
