Page 2: PIPES Program0E70FC86-94C4... · Strategic Goal 1: Adopt infrastructure maintenance and modernization strategies that maximize performance, reduce risk and ensure reliable service

Purpose and Effects

of the Program The proposed Program is intended to reduce

inflow and infiltration (I/I) as well as service calls

by providing financial incentives to property

owners to repair or replace their sewer laterals.

The reduction in I/I will reduce the risk of Sanitary

Sewer Overflows (SSOs) throughout our service area,

as well as illicit discharges at the Water Quality &

Resource Recovery Plant (WQRRP).

What Is I/I

I/I can enter into

Into WCW’s sewer

system as a

result of

several sources.

Page 6: PIPES Program0E70FC86-94C4... · Strategic Goal 1: Adopt infrastructure maintenance and modernization strategies that maximize performance, reduce risk and ensure reliable service

Background/DiscussionThe Program

aims to provide I/I

relief, especially

in the high I/I

(red) areas.

Page 7: PIPES Program0E70FC86-94C4... · Strategic Goal 1: Adopt infrastructure maintenance and modernization strategies that maximize performance, reduce risk and ensure reliable service

Proposed Program

Components

Incentive disbursements are available in varying amounts up to a maximum of $4,500 & will not exceed 50% of the lowest submitted bid.

Laterals longer than 100 feet, deeper than 10 feet or located in high I/I areas have higher disbursement eligibility.

Page 8: PIPES Program0E70FC86-94C4... · Strategic Goal 1: Adopt infrastructure maintenance and modernization strategies that maximize performance, reduce risk and ensure reliable service

Proposed Program

Components

1 incentive disbursement per property

owner, per property located within WCW

boundaries.

No incentive disbursements will be

provided for construction performed prior

to receiving pre-approval.

Page 9: PIPES Program0E70FC86-94C4... · Strategic Goal 1: Adopt infrastructure maintenance and modernization strategies that maximize performance, reduce risk and ensure reliable service

Proposed Program

Components

Applicants must submit an application, a

video inspection letter, a sewer lateral

inspection form & at least 3 construction

bids with non-collusion forms (one per

contractor).

Page 10: PIPES Program0E70FC86-94C4... · Strategic Goal 1: Adopt infrastructure maintenance and modernization strategies that maximize performance, reduce risk and ensure reliable service

Recommendation

Authorize the General Manager to commence the

PIPES Program.

Approve an amendment to the current Biennial

Budget to reflect an allotment of $400K for FY 2021.

Report

Page 48: PIPES Program0E70FC86-94C4... · Strategic Goal 1: Adopt infrastructure maintenance and modernization strategies that maximize performance, reduce risk and ensure reliable service

Project Highlights

The following challenges were encountered:

Unforeseen subsurface conditions (boulders

significantly obstructing trench paths)

Setting up bypasses to maintain continuous wastewater

collection and transport services during construction

Page 49: PIPES Program0E70FC86-94C4... · Strategic Goal 1: Adopt infrastructure maintenance and modernization strategies that maximize performance, reduce risk and ensure reliable service

Project Highlights

Lessons learned:

Draft specifications to clearly delineate between

additive items and base items. Both were needed;

therefore, the project scope was completed despite

this issue.

Page 50: PIPES Program0E70FC86-94C4... · Strategic Goal 1: Adopt infrastructure maintenance and modernization strategies that maximize performance, reduce risk and ensure reliable service

Fiscal Impact

Total project budget amount was $1,700,000

The total project expenses were $889,039

Emissions Categories• Scope 1 –– Direct emissions are generated by sources within WCW’s

organizational boundaries and within the ownership or control of WCW.

• Scope 2 ––Includes emissions that occur at sources owned or controlled

by entities other than WCW, but result from activities located within WCW’s

organizational boundaries. Associated exclusively with purchased or acquired

electricity, steam, heating, or cooling.

• Scope 3 –– Indirect emissions related to WCW operations, which are

generated by sources outside WCW’s financial or operational control. Includes

all indirect emissions not covered by the Scope 2 category.

• Biomass Combustion or Biogenic CO2 (BC) –– Directly

emitted carbon dioxide (CO2) from combustion of renewable biomass that is

considered a part of the short-term carbon cycle. Similarly, biogenic CO2 that

arises as a part of the organization’s value chain is categorized BC.

Highlights• Largest Sources of Emissions–– The Biosolids storage lagoons

and residual effluent Nitrogen.

• Fugitive Emissions –– Fugitive emissions of Methane (CH4) and

CO2 created by wastewater collection systems.

• Process Emissions –– Plant Processes estimated at 7% of Scope 1

plus Scope 2 emissions.

• Electricity -- Electricity consumption estimated at 6%.

• Fleet -- WCW vehicles and equipment each estimated at 4%.

• Onsite Energy Projects – Existing Biogas recovery and a solar

photovoltaic (PV) systems reduce emissions.
