   Since ground and ambient installation conditions as well as crew skills can affect the success or failure of a cure cycle, testing is performed by 3rd party laboratories in normal cases and should be requested by the owner.

3. Utility location - Wikipedia

   en.wikipedia.org/wiki/Utility_location

   Location by these technical means is necessary because maps often lack the pinpoint precision needed to ensure proper clearance.

   The decision to build a combined sewer system or two separate systems is mainly based on the need for sewage treatment and the cost of providing treatment during heavy rain events. Many cities with combined sewer systems built their systems prior to installing sewage treatment plants, and have not subsequently replaced those sewer systems. [2]

   Orangeburg was a low cost alternative to metal for sewer lines in particular. Lack of strength causes pipes made of Orangeburg to fail more frequently than pipes made with other materials. The useful life for an Orangeburg pipe is about 50 years under ideal conditions, but has been known to fail in as little as 10 years.

   When underground sewer lines are laid close to the ground level (this may be at the depths of less than 0.75 metres (2.5 ft) or 2 metres (6.6 ft) depending on local regulations), an inspection chamber is used as an access point instead. [6] [7] Inspection chambers allow access to sewer lines without requiring a person to get in them. [6]

   There are two methods used to install a slipline: continuous and segmental. Continuous sliplining uses a long continuous pipe, such as HDPE, Fusible PVC, or Welded Steel Pipe, that are connected into continuous pieces of any length prior to installation. The continuous carrier pipe is pulled through the existing host pipe starting at an ...
