Clawson’s Housing Stock — Why Older Infrastructure Matters

Clawson is a small city — just under 3 square miles — bordered by Troy to the north, Royal Oak to the south and west, and Madison Heights to the east. Its residential character closely resembles Royal Oak’s: densely built postwar bungalows and ranch homes on modest lots, with a mature tree canopy that has had six decades to establish root systems in and around aging clay sewer infrastructure.

Most of Clawson’s residential sewer laterals were installed when the homes were built in the 1950s and 1960s — clay tile pipe that is now 60–70 years old. Clay tile pipe has bell-and-spigot joints every 4 feet, and those joints are where tree roots enter. The silver maples and elms that were planted in Clawson’s postwar neighborhoods are now mature, with root systems that span front yards and extend across the underground paths of sewer laterals. Root intrusion at aging clay joints is the dominant sewer failure mode in Clawson — the same pattern seen throughout Royal Oak’s adjacent neighborhoods.

🏠 Clawson’s Plumbing Context

Because Clawson’s housing stock is a decade older than most of Troy’s, the sewer lateral picture is closer to Royal Oak’s than to Troy’s newer subdivisions. The good news: the same trenchless repair approach that works well in Royal Oak — camera inspection confirming root intrusion, CIPP lining sealing all clay tile joints permanently — applies directly to Clawson’s laterals.

🔌 1950s–60s Clay Laterals

60–70 year old clay tile with bell-and-spigot joints every 4 feet — the same infrastructure profile as Royal Oak’s postwar neighborhoods. Root intrusion at joints is the primary failure mode.

🌿 Mature Tree Root Pressure

Silver maple and elm root systems established over 60–70 years. Root intrusion that started as hairline entry at a clay joint grows to a full blockage within a few growing seasons if untreated.

🔌 Cast-Iron Branch Drains

The interior branch drain lines (kitchen, bathroom, laundry) in Clawson’s older homes are also cast-iron — accumulating scale and grease buildup over decades that requires hydro jetting rather than snaking to fully clear.
