Planned Future Major Capital Expenditures REQUIRED to Protect
Public Health

¢ Over $85 million in upcoming capital investments are required over the next 5 -
15 years :
¢ Pump Stations Rehabilitation (Phase 2): $5.8 million

CMOM Plan (Capacity, Management, Operation & Maintenance): $5.2 million

Class A Biosolids: $5.0 million

Siphons Repair: $2.0 million

Green Infrastructure for Stormwater Control: $3.0 million

Sewer Infrastructure Program: $30.4 Million ($6 million annually)

compliance with its environmental permits issued by the US Environmental Protection Agency to avoid
costly fines due to permit violations as a result of failed infrastructure.
