Remove Old Drainage Pipes and Install New Hybrid System

What happens here

Locate and remove the existing 3-inch white drainage pipes, which are likely compromised by root intrusion as indicated by the initial assessment. Install new 6-inch green solid pipes to serve as the main downspout lines. Simultaneously, lay down a separate French drain system using white corrugated pipe. This creates a 'hybrid system' where the hard pipe handles downspout runoff and the French drain collects groundwater. The French drain should be laid within the excavated trench, often wrapped in geotextile fabric. Both the solid downspout pipes and the French drain are routed towards the pre-existing cutout in the storm sewer inlet. The city's regulations allow only one connection point, so the French drain pipe is merged into the solid downspout pipe just before entering the storm sewer inlet. Avoid creating separate perforations into the storm sewer system unless explicitly permitted.

Goal: After excavation, remove the old 3-inch drain tile system. Install a new, larger 6-inch solid pipe for downspout connections and a separate French drain system (corrugated pipe) to collect groundwater, connecting both into the existing storm sewer inlet.
