Who pays for the sewer lateral in Lancaster, CA

Who is responsible for which part

The pipe is yours to the main, fitting and all: the code makes each owner responsible for "the entire house lateral up to and including the wye or tee in the city's main line", and defines that lateral as the part "within the street or right-of-way". If nobody can tell where a blockage is, Lancaster will dig to find out - and the answer decides the bill. Fault in the City's sewer is repaired "at no charge to the property owner"; fault in your lateral and you "shall reimburse the city for all costs necessarily incurred".

The property owner

The whole house lateral, including the fitting where it meets the main. Section 13.07.060 provides that "each property owner is responsible for the installation, repair and maintenance of the entire house lateral up to and including the wye or tee in the city's main line", and that each owner "shall keep his/her house lateral in good working order at his/her own expense". The code defines a house lateral as "that part of the sewer piping within the street or right-of-way which extends from the property or sewer right-of-way line to a connection with the main-line sewer" - so the length beneath the road is the owner's, and the City's own duty runs only to "any main line public sewer in a dedicated right-of-way". The owner is also "responsible for damage to any of the city's property comprising any part of the public sewer system which results from the owner's use, repair or maintenance" of it.

What is required

• Any timeWork required

  Because your responsibility in Lancaster runs "up to and including the wye or tee in the city's main line", a full lateral replacement reaches the City's main - and the code requires the City to be told first and to supervise that part: "if repair and/or maintenance of the house lateral extend into the main line sewer the director shall be notified prior to any work in the main line sewer being performed and that portion of the work affecting the main line sewer shall be performed under the supervision of the director". The owner is separately "responsible for damage to any of the city's property comprising any part of the public sewer system" resulting from their own use, repair or maintenance of the lateral.

  What to do: Ask your contractor whether the work will reach the main - for a full replacement the answer is yes - and if it will, notify the director before anything is booked, so the supervision can be scheduled rather than waited for. While you are on the phone, ask whether the City would rather investigate the fault itself first: where the location of a malfunction is disputed or cannot be seen from the surface, the City may open the street to find out, and if the fault turns out to be in its own sewer the repair is at no charge to you.

  Why this matters▸▾

  In Lancaster this clause catches every full replacement, because the fitting is yours. Two things follow. The notification is a prerequisite rather than a courtesy - work in the main without it is work the code did not permit - and it needs to be in the programme before a contractor is booked, not discovered on the day. And the damage clause means a contractor who breaks the main while connecting to it has created a bill that lands on the property owner, so it is worth knowing what your contractor's insurance covers before they start.
