Cotati's Sewer Line
Specialists
Cotati is a tiny college-adjacent town of 7,500 residents directly south of Rohnert Park, notable for its rare hexagonal historic Plaza laid out in 1893 — one of only two six-sided town plazas in the United States. The residential inventory is concentrated in the 1950s–2000s with a small original hexagonal townsite at its core. Old Town and the blocks immediately surrounding Cotati Plaza contain pre-1940 homes with original clay or Orangeburg sewer laterals. The mid-century expansion along Page Street, East Cotati Avenue, and Henry Avenue produced 1950s–70s Orangeburg pipe now well beyond service life. The 1990s–2000s added Liman Way and Stage Coach Glen with modern ABS or PVC. Cotati's high concentration of Sonoma State University rental housing in older blocks means many sewer lines have seen heavy multi-occupant use. The City of Cotati Planning Department administers all sewer permits and Repipe Champions handles those filings on your behalf.
Repipe Champions specializes exclusively in pipe replacement, including full sewer line repipe and trenchless CIPP lining. We serve every Cotati neighborhood with online inspection booking, same-day estimates, and next-day scheduling available.
Every sewer project we complete is permitted, city-inspected, and backed by our 30-year parts and labor warranty. We handle all permitting through the City of Cotati Planning Department — Building Division on your behalf.

Sonoma County homes have two paths to a fully restored sewer line. We assess both options at every free estimate and recommend the most cost-effective solution for your specific situation.
Sewer Line Repipe
Full excavation and replacement of your existing sewer line with new Schedule 40 PVC pipe. The most durable, longest-lasting solution, particularly for severely deteriorated or root-damaged lines.
Trenchless Sewer Lining
A cured-in-place pipe (CIPP) liner is inserted and expanded inside your existing sewer line, creating a seamless new pipe within the old one, without digging up your yard, driveway, or landscaping.
Does Your Cotati Home
Need Sewer Work?
These are the most common signs of a failing sewer line in Sonoma County homes.
Slow Drains Throughout
When multiple drains in your home run slow simultaneously, the problem is almost always in the main sewer line, not individual fixtures.
Sewage Backups
Raw sewage backing up into your tub, shower, or lowest fixtures is a sign of a blocked or failed sewer line requiring immediate attention.
Unusually Green Lawn
A strip of exceptionally green or lush grass over your sewer line is a classic sign of a slow leak: the sewage is fertilizing the soil above.
Sewage Odors
Persistent sewage smell in your yard or home often indicates a crack or separation in the sewer line allowing gas to escape.
Root Intrusion
Tree and shrub roots naturally seek moisture and nutrients in sewer lines. Once roots enter, they grow rapidly and can cause complete blockage.
Home Built Before 1980
If your Cotati home was built before 1980 and has never had a sewer camera inspection, scheduling one is a prudent first step regardless of symptoms.
We Know Cotati
Sewer Systems
Cotati is a tiny college-adjacent town of 7,500 residents directly south of Rohnert Park, notable for its rare hexagonal historic Plaza laid out in 1893 — one of only two six-sided town plazas in the United States. Its residential inventory is concentrated in the 1950s–2000s with the small original hexagonal townsite at its core. Old Town and the blocks immediately surrounding Cotati Plaza contain the city's oldest homes — pre-1940 cottages and 1900s–20s structures with original clay or Orangeburg sewer laterals. The mid-century expansion along Page Street, East Cotati Avenue, and Henry Avenue produced 1950s–70s homes with Orangeburg now well past service life. The 1990s–2000s buildout added Liman Way and Stage Coach Glen with modern ABS or PVC. Cotati's proximity to Sonoma State University in adjacent Rohnert Park drives a high concentration of student rental housing, much of it in the older central neighborhoods.
🏗️ Cotati Sewer Pipe Context
Cotati's Old Town and Plaza-area homes from the early 1900s have clay or Orangeburg laterals at or beyond end of life. Mid-century Orangeburg along Page Street and East Cotati Avenue is failing in the typical end-of-service window. Liman Way and Stage Coach Glen from the 1990s–2000s have sound modern ABS or PVC. The high concentration of student rental properties in the older central neighborhoods means many sewer lines have decades of heavy multi-occupant use.

Cotati Sewer Permit

A permit is required for all sewer line work in Cotati. Unpermitted sewer work creates serious liability at resale and can void homeowner insurance coverage for related water damage.
