Root Intrusion

Roots are a very common problem for sewer lines constructed prior to the early 1980's. This is because these sewer lines were built using VCT (vitreous clay tile) pipe. Clay tile pipe is a ceramic product dating back to the Roman aqueducts and is an ideal material for transporting water since it is inert. Clay tile pipe is also an ideal material for use in difficult environments since it is amazingly strong, having nearly a 3/4" thickness, and is virtually impervious to deterioration from normal use. However, its multiple joints are a downside. Clay tile pipe tends to leak water at the joints, making a wonderful water source for thirsty trees and shrubs.

Sag or Belly

A Sag or Belly is where the sewer pipe has lost positive slope going to its destination. Typically, sewers flow by gravity to where they tie into the city's main sewer.

Separations, Collapse & Cracks

Separations, Collapse & Cracks in a sewer pipe can occur from a variety of sources, including poor original installation, poor soil bedding, root penetration or structural deterioration due to the age of the pipe. In addition to structural impacts, these conditions allow exfiltration of household waste and infiltration of clean groundwater into the wastewater sewer system.

Debris / Grease

Debris / Grease debris can build up in a side sewer if there are structural defects or obstructions in the pipe (such as sags, roots or offset joints) that obstruct the flow of the sewer and if inappropriate items are flushed or poured down the drains. Or, if pipes are constructed at slopes less than the recommended ¼-inch drop per foot of pipe, the liquids won't be moving fast enough to carry away the solids in the pipe. If debris build up is severe enough, it can eventually fill a pipe and cause backups or slow-draining sewers.

Pipe Bursting

Pipe bursting is a method of replacing buried pipelines (such as sewer, water, or natural gas) without the need for a traditional open cut trenching. One or more pits are required to launch and receive the new pipe. Pipe bursting may also be used to expand pipeline carrying capacity by replacing smaller pipes with larger ones, or "upsizing." Extensive proving work by the gas and water industries has demonstrated the feasibility of upsizing sewer, gas and water mains and laterals.

Cured In Place Pipe(CIPP) lining:

A cured-in-place pipe (CIPP) is one of several trenchless rehabilitation methods used to repair existing pipelines. CIPP is a jointless, seamless, pipe-within-a-pipe with the capability to rehabilitate pipes ranging in diameter from 0.1–2.8 meter (4"–110"). As one of the most widely used rehabilitation methods CIPP has application in water, sewer, gas, and chemical pipelines.

Open Cut Construction:

This method of construction is the typical dig and replace that most people are familiar with. This is the most common method of repairing side sewers and consists of digging up the old pipe and replacing it with new pipe. Open cut may be less suitable for areas where there are significant surface improvements that a property owner wants to avoid disturbing and that are costly to replace or when side sewers are fairly deep.

Spot Repairs

If the majority of a pipe is good condition with little or no defects, a spot repair may be the most suitable and cost effective method for repair. The property owner should consider a full sewer replacement or rehabilitation if there are multiple defects throughout the pipe. It is generally less costly to hire a contractor once than to have a contractor mobilize to a site multiple times with repeated spot repairs.

Snaking

Snaking is more commonly performed to eliminate large objects accidentally introduced into a sewer system, non-biodegradable napkins, grease, oil or soap residue that collects on the pipe sidewalls, and roots. A drawback to this method is the damage that may occur in Plastic pipe, Orangeburg pipe and Deteriorated pipe regardless of composition. Snaking to eliminate roots is primarily a temporary solution and requires ongoing maintenance that may be frequent depending on how aggressive the vegetation is.
