 | | Sanitary Sewer Program Management & Planning (EPMC- IIIA) - This planning allows WASA to assess the sewer system to determine if it is in adequate structural condition, and has sufficient capacity to meet current service demands and planned growth. |
 | | This program includes large diameter sewers that may be required to serve new development, replace undersized sewers, or replace or rehabilitate large diameter sewers that have reached their useful life or are in need of major repair. |
