Project Name: Southeast Atlanta Green Infrastructure Initiative (SAGII) Phase 3 – Connally Vault

The Connally Storage Vault project is a key component of Phase 3 of the Southeast Atlanta Green Infrastructure Initiative (SAGII) program. This underground passive storage tank will address combined sewer capacity issues by providing detention and managed release of combined storm and sewer flows. The vault is designed to intercept and detain the flows in the West Connally (84-inch inverted teardrop shaped brick sewer) and East Connally (78-inch circular pipe) combined sewer trunk lines. The location of the proposed 7.8 million-gallon vault is between Connally and Ami Streets, bounded on the north by Georgia Avenue. The storage vault will provide a direct reduction to the surface flooding that has historically impacted this community.

The scope of this project includes:
Installing a 7.8 million-gallon combined sewer storage vault upstream of the Peoplestown Junction Box.

Justification:

• Captures stormwater to reduce runoff and overflows in the community
• Protects public health and safety
• Adds aesthetic enhancements for the corridor and surrounding neighborhoods
