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
