Pipeline Replacement Project

Why we need to replace the force main

Silicon Valley Clean Water

We have a Problem we need to Solve

• Our purpose for existing is to…– Protect Public Health– Protect the Environment

• We have an old, leaking pipe– Sewage into streets or bay– We have to do something– Doing nothing is not an option• From both a legal and ethical standpoint

The Problem we need to Solve

• Reinforced Concrete Pipe– Useful life = 50 years (insert ref)– Our pipe is 45 years old– Originally Designed for gravity flow (low pressure)– Currently Operating at 2.5 times design pressure– 64 leaks so far; rate of leaks increasing– Leaks are time-consuming and expensive to repair

Leak Repair

…from small disruption and impact

…to large

Pipe Repair Costs

• Each repair costs from $300,000 to $600,000• A small repair will take 3-5 weeks to complete• A large repair could take 3 weeks to several

months• So far we’ve had 64 of leaks at a cost of $xxx• Costs do not include potential regulatory, civil,

and even criminal penalties

Aging Infrastucture

• In the U.S., it is estimated that aging infrastructure will cost $xxx,xxx,xxx,xxx

• SVCW, alone, is replacing aging infrastructure at a cost of over $500 million

• In our immediate area other large projects– San Jose is spending $xx billion– San Francisco is spending $xx – Sunnyvale is spending $xx

Aging Infrastucture

• American Society of Civil Engineers give U.S. a grade of “C-/D check” for wastewater systems
