Maintenance Margin: 150 USD

Municipal water access functions not as a public utility, but as a collateralized asset subject to automated margin call liquidation, where physical dehydration ensures bond market solvency.

wall text

In post-bankruptcy Detroit, municipal utility infrastructure operates under strict financialization protocols. This installation maps mark-to-market debt monitoring directly onto domestic plumbing. When residential accounts breach past-due limits, automated tracking triggers a maintenance margin call. Rather than a human administrative delay, the system acts like an automated brokerage liquidation: a motorized actuator engages the physical curb stop valve, severing water flow to enforce municipal bond solvency. The accompanying printouts format DWSD shutoff notices as algorithmic liquidation tickets, exposing how physical utility access is subordinated to debt obligations and secondary capital flows.

anchor facts used

In 2014, the city awarded a $5.6 million contract to private demolition company Homrich Inc. to execute mass water shutoffs.
Shutoffs are triggered automatically when a residential account is 60 days late or strictly $150 past due.
The Detroit Water and Sewerage Department (DWSD) leased regional infrastructure to the Great Lakes Water Authority (GLWA) for $50 million annually to satisfy bond debt.

mechanism

Mark-to-market accounting — DWSD billing databases are scraped daily to calculate the liquid equity of Detroit residential accounts, measuring balances against a strict financial floor.
1. Asset Monitoring
Maintenance Margin Breach Notification — A gallery-mounted thermal printer dispenses a physical blue tag for each account breaching the threshold, sequentially generating thousands of paper liabilities.
2. The Margin Call
Brokerage Asset Sell-off — A motorized mechanical arm actuates a physical solenoid valve, instantly stopping water flow to a hydroponic representation of the corresponding Detroit zip-code topology.
3. Forced Liquidation
Automated Clearing House (ACH) sweep — The diverted water volume is forcefully routed via clear acrylic tubing into a central, overflowing glass reservoir representing regional lease capital.
4. Capital Reallocation

curatorial qa (machine verdict, unedited)

SCORE 3/5 after 2 attempt(s)
READS: The curbside shutoff valve in front of Detroit brick bungalows, the digital metering hardware, and the mechanical wrench actuating to cut water flow.
FAILS: The blue glowing valve reads as generic sci-fi CGI rather than municipal automation. The mechanical arm appears abruptly without a structural rig, and the margin call financial transposition is entirely absent from the video without the printed artifact.
