While the idea of reusing historic industrial infrastructure is creatively appealing, running a new line within the original “Ford water line” system for fish farming (aquaculture) is not feasible in 2026.
The original system is no longer a “live” network you can simply tap into. Instead, the strategy for 2026 is to build a modern Recirculating Aquaculture System (RAS) on the site, using the brand-new water mains currently being installed by the City of Highland Park.
1. Why the Old Ford Lines are Unusable
The 1915 infrastructure was designed for a “Once-Through” cooling model, which is the opposite of how modern fish farming works.
- Irreparable Decay: The old Ford intake lines and 45-million-gallon reservoir were decommissioned in 2012. Inspections found the valves and “turbidimeters” (water clarity sensors) to be in total failure.
- Contamination Risk: Historic industrial pipes often used lead joints or wooden stave sections. Using them for fish farming would likely introduce heavy metals or pathogens that would kill your stock.
- The “Leakage” Problem: Highland Park’s old system lost 70% of its water to leaks. Any attempt to pressurize those old lines today would likely cause massive sinkholes on the property.
2. The 2026 Solution: Recirculating Aquaculture (RAS)
Instead of a “new line in an old pipe,” modern fish farming in Michigan uses closed-loop technology. This is much more compatible with your 70/30 crowdfunding model because it is a controlled, high-tech factory rather than a high-risk plumbing project.
| Feature | Old Ford Line (Flow-Through) | Modern RAS (Closed-Loop) |
|---|---|---|
| Water Source | Detroit River (Direct Intake) | New 2026 Highland Park Mains |
| Water Usage | Millions of gallons daily (Wasteful) | 90% water reuse (Efficient) |
| Regulation | High (EPA/EGLE discharge permits) | Low (Municipal water connection) |
| Investor Risk | High (Pipe failure/Contamination) | Low (Predictable environment) |
3. Feasibility of Fish Farming in Highland Park
The site of the old Ford plant is actually excellent for a modern aquaculture facility for several reasons:
- New Infrastructure: The city is currently (as of Jan 2026) replacing water mains in the Southeast Quadrant. You would be connecting to brand-new, lead-free pipes.
- Flat Industrial Land: The massive concrete pads from the Ford era provide a perfect foundation for the heavy tanks used in fish farming.
- Power Access: The site remains a major electrical hub, providing the high-voltage power needed to run the 24/7 filtration and oxygenation pumps.
4. Pro-Forma: The “Fish Farm” Deal
If you were to crowdfund this today, your 70/30 split would look like this:
- The Capital: You raise $5M–$10M for the “RAS Factory” and building.
- The Revenue: You sell tilapia, salmon, or shrimp to the Metro Detroit restaurant market (locally grown, “Detroit-branded”).
- The Exit: After 5 years, you sell the stabilized “Ag-Tech” business to a larger food conglomerate.
Summary Table: Your Project Outlook
| Milestone | Status (2026) |
|---|---|
| Water Supply | Ready. New city mains provide clean, reliable source water. |
| Historic Pipes | Avoid. Too much liability; focus on brand-new internal PVC/Steel. |
| Zoning | Favorable. Highland Park is encouraging “Green Industrial” use. |
