Project Elements:

Filter Influent Pumping Station (FIPS) Pumps up to 343 MGD of Secondary Effluent

from the Secondary Settling Tanks (SSTs) to

Filters

One drum screen (and channel for future) for

bird and algae removal

3 duty and 1standby pump (6 pumps for buildout)


Project Elements: Granular Media

Filtration (GMF) Facility

Chemical mixing (coagulant, filter aid),

20 granular media filters,

During winter months (November-April) flows in excess of the filtration capacity

of 217 MGD will be diverted around filtration.

Seasonal Flow Diversion Structure

(SFDS),


Project Elements: Granular Media

Filtration (GMF) Facility

Filters are dual media, composed of anthracite and sand

Backwash supply system, and

Spent backwash equalization

tanks and pumps.

Project Elements: GMF

Support Building Layout

• Support building centered on

GMF structure

FTE Flash Mix Moved to South End of GMF• Filtered effluent (FTE) flash mix

was relocated to the south side of

GMF

– Based on flow separation (TM9)

– Flash Mix is now at 96” lines

near the flow meter vault


Project Elements:

Disinfection Contact Basins (DCB) Filtered effluent will be mixed with disinfectant (sodium hypochlorite) at filters and

conveyed to the DCBs.

One dedicated DCB (#4) will produce Title 22 effluent year-round for unrestricted reuse

DCBs (#1-3) will disinfect filtered and seasonal secondary effluent for river discharge

Unfiltered secondary effluent that is diverted during winter high flow events will be blended

with the filtered water and disinfected through DCBs (#1-3).


EOS Magnetic Flow Meters


TTF Construction Cost Estimate

• $340-$372 Million

$1.6M March 2018


Upcoming Projects (Continued)

Regional San Projects – Near-Term

PROJECT SUMMARY EST. COST ADVERTISE DATE

Extended Forecast

ESB-D Liner Replacement Replace existing membrane liner on Emergency Storage

Basin D. Anticipate new liner will be concrete, similar to

EchoWater FEQ project.

$22M 2019

RTP I/O Controller

Replacement

Replace old, obsolete plant control system

components. Design will follow system architecture

established for EchoWater processes, which is local

PLC controllers. This is expected to be a multi-year

project due to operational constraints.

$15M 2019

South County Ag Recycled

Water, Phase 1Construct new pump station and conveyance pipeline to

deliver tertiary treated wastewater to agricultural

interests in south Sacramento County. Anticipate

multiple contracts for first phase improvements.

$140M 2020

EchoWater Projects are Designed

using BIM

• BIM files may be available for

4-D (schedule) and 5-D (cost)

management.

• Responsibility for maintaining

model files to reflect changes,

and “as-built” conditions,

during construction TBD.

• Use of asset database for

submittals (shop drawings,

O&M information, etc.) TBD.
