Who is responsible for which part

Monrovia puts the whole lateral and its junction with the main on the owner. Section 13.12.040 provides that "All sewer laterals shall be maintained by the owner of the property served by such lateral in a safe and sanitary operating condition so that there is no seepage of waste at any point up to and including the junction of the sewer lateral and the sewer main".

The property owner
The lateral from the building to the main, the junction included. The same section defines the sewer lateral as the connecting line running from the Y connection at the main "to the private property line and extending to the structure to which it connects", and says the sewer main "shall not include sewer laterals".
What else is worth knowing
Nothing conditions the split, and the owner's duty is framed as a standard rather than only a pipe: the lateral must be kept so that "passage of waste through the lateral to the sewer main is free from stoppage and obstruction", which makes a blockage anywhere along it - under the street included - the owner's to clear. These sections govern property on the City's sewer; check the name on your sewer bill if you are not sure the City serves you.

What is required

  • When you askPermit

    Monrovia Municipal Code section 12.08.010 makes it unlawful to make "any excavation in or under the surface of any public place for the installation, repair or removal of any pipe, conduit, duct or tunnel or for any other purpose without first obtaining from the street superintendent a written permit to make such excavation and paying all fees for permit, inspection and trench resurfacing."

    What to do: Before a repair in the street, have the contractor apply to the street superintendent for the excavation permit. For a repair or a service connection the application does not need the usual plat - section 12.08.010 waives it for excavations "made for service connections for the location of trouble in conduits or pipes or for making repairs thereto".

    Why this matters

    The owner's lateral runs to and includes its junction with the main, so a repair under the street is the owner's - and it needs the street superintendent's written permit, with fees for inspection and trench resurfacing, before the pavement is opened.

Your other pipe has a different answer

The drinking water line coming into your property is a separate pipe, run by a separate authority, and who is responsible for it is decided separately. Your sewer lateral is yours to the main, fitting included; your water line stops being yours at the meter.
