    What it covers:
    connecting to the District's sanitary sewer system, which needs a sewer connection permit or a wastewater discharge permit

    West Valley Sanitation District's ordinance code states that "it shall be unlawful for any person to discharge or deposit any substance or connect to the district's sanitary sewer system without a valid sewer connection permit and/or wastewater discharge permit issued by the district pursuant to this code". It also provides that "the requirement to install a property line cleanout shall be imposed by the district for any work requiring a district permit, or when in the district manager's opinion, the lower sewer lateral has experienced a high frequency or severity of blockages, or when an existing property line cleanout is deemed not to conform with district design standards". As amended by Ordinance 156 (9 September 2026), the code also provides an alternative: the cleanout, which the code calls the "PLCO", is required "unless the property owner files with the district a properly executed district release of liability for the maintenance, cleaning, and repair of the PLCO and lower lateral".

Who is responsible for which part

The District's ordinance code says "the lower sewer lateral is owned by the district" - the run from the property line cleanout to the sewer main in the street. On who maintains it, the code says more than one thing. It says the District "will maintain" the lower lateral and "is generally responsible for the maintenance, cleaning, inspection, repair, and replacement" of it. But for lower laterals and cleanouts installed before 1 November 2026, a further sentence reads "the district may continue to maintain, clean, inspect, and repair existing lower sewer laterals", on conditions, and the code does not say how these fit together. Where your side ends is not fixed either. The code's definition puts it at the cleanout, the cleanout included, "unless otherwise provided by district ordinance or policy", and another section names both the cleanout and the connection at the public sewer. Without an approved, accessible cleanout, the maintenance of the whole run to the main is yours. Confirm with the District where your side ends and whether it will maintain, repair or replace the rest before relying on it.

The lower lateral: "the portion of a building sewer extending from the property line cleanout (PLCO) to the connection with the public sewer main", in the public right-of-way. The code says "the lower sewer lateral is owned by the district". Its provisions on maintaining it do not say the same thing. The lower-lateral definition says the District "is generally responsible for the maintenance, cleaning, inspection, repair, and replacement of the lower sewer lateral from the property line to the public sewer, subject to the provisions of this code". It then says that for lower laterals and PLCOs installed before 1 November 2026, "the district may continue to maintain, clean, inspect, and repair existing lower sewer laterals, provided such facilities were properly permitted, and installed in accordance with applicable standards in effect at the time of installation, and safely accessible". That sentence is a "may", and it leaves out replacement. The cleanout definition says "the district shall be responsible only for the maintenance, cleaning, inspection, and repair of the lower sewer lateral from the PLCO to the public sewer", and its copy of the sentence for existing laterals reads "shall may continue". Section 6.100 says the District "will maintain that part of each building sewer lying within a public right-of-way (lower sewer lateral) from PLCO to the public sewer". It also says that "if a properly installed, maintained, and accessible property line cleanout exists" the District will remove blockages, remove or treat roots, and carry out "repair or replacement of all, or a part of the lower sewer lateral" when "replacement becomes more economical than the maintenance being performed by the district". The other condition in that sentence, "when its condition is deemed, by the district manager", is left unfinished in the code. The code does not say how these provisions fit together, so ask the District what it will do for your lower lateral.
The property owner
The code's definition makes property owners responsible for "the upper sewer lateral from the building to the PLCO including the PLCO, unless otherwise provided by district ordinance or policy" - PLCO being its name for the property line cleanout. Section 6.100(C) adds "any PLCO installed in the public right of way" between the two halves. A new cleanout goes "approximately two (2) feet behind the property line", or, where the site makes that impractical, somewhere the District approves, such as behind the curb or in the sidewalk. Section 6.100(C) also states: "The owner's operation and maintenance responsibility is from the building to the connection at the sanitary public sewer, or the PLCO closest to the public sewer." That names a second end point, and the code does not say when each applies. Where no approved cleanout is in place and kept clear for the District's staff, "the maintenance obligation for the entire building sewer and any resultant backup or sanitary sewer overflow due to the lack of maintenance shall be the responsibility of the property-owner", and "responsibility for the repair or replacement of the lower lateral located within the public right-of-way shall be determined by the district manager on a case-by-case basis". Where the lateral connects to a public sewer in an easement, "the entire sewer lateral, including any cleanouts, shall be the responsibility of the property owner".

What decides which applies

Two things bear on this, and the code fully settles neither. The first is the cleanout. The code's cleanout definition puts the divide there: the cleanout "serves as the point of separation between the upper sewer lateral from the lower sewer lateral", and your side runs to it, the cleanout included, "unless otherwise provided by district ordinance or policy". Section 6.100(C) names two end points for the owner, "the connection at the sanitary public sewer, or the PLCO closest to the public sewer", without saying which applies when. Where "an approved property line cleanout has not been installed to access the lower sewer lateral, or has not been maintained to provide clear and unfettered access for district maintenance staff", the maintenance of the whole building sewer is yours, and the district manager decides case by case who repairs or replaces the lower lateral, weighing among other things "whether the failure could have been prevented through proper maintenance by the property owner". The second is when your lateral went in. For lower laterals and cleanouts installed before 1 November 2026, a sentence in the code's definitions says the District "may continue" to maintain them, on conditions. Elsewhere it says the District "will maintain" the lower lateral, and it does not reconcile the two. So ask the District where your side ends and what it will do beyond it before relying on either. One case is settled outright: where your lateral connects to a public sewer in an easement, the District "shall not be responsible for the maintenance, cleaning, inspection, repair, or replacement" of it, and the whole lateral is yours.

  • Before work on the pipePermit
    Who issues it:
    West Valley Sanitation District
    What it covers:
    connecting to the District's sanitary sewer system, which needs a sewer connection permit or a wastewater discharge permit

    West Valley Sanitation District's ordinance code states that "it shall be unlawful for any person to discharge or deposit any substance or connect to the district's sanitary sewer system without a valid sewer connection permit and/or wastewater discharge permit issued by the district pursuant to this code". It also provides that "the requirement to install a property line cleanout shall be imposed by the district for any work requiring a district permit, or when in the district manager's opinion, the lower sewer lateral has experienced a high frequency or severity of blockages, or when an existing property line cleanout is deemed not to conform with district design standards". As amended by Ordinance 156 (9 September 2026), the code also provides an alternative: the cleanout, which the code calls the "PLCO", is required "unless the property owner files with the district a properly executed district release of liability for the maintenance, cleaning, and repair of the PLCO and lower lateral".

    What to do: If the District requires a cleanout, the code gives you "up to three hundred sixty-five (365) calendar days from the date of issuance" where the permit is mainly for other work, and "sixty (60) calendar days" where the permit is specifically for the cleanout. The installation must be done by a contractor registered with the District. Ask which deadline applies when the permit is issued, not later. The code's alternative to the cleanout is "a properly executed district release of liability for the maintenance, cleaning, and repair of the PLCO and lower lateral", and it says nothing more about that release. Ask the District what filing one would mean for the maintenance of your lower lateral before choosing it.

    Why this matters

    That cleanout bears on where your side of the pipe ends. Without an approved one kept clear for the District's staff, the code puts "the maintenance obligation for the entire building sewer" on you, out to the main, and leaves the repair or replacement of the lower lateral under the street to the district manager, case by case. With one, the code's definition of the cleanout ends your side at it, the cleanout included, "unless otherwise provided by district ordinance or policy" - though another section names the connection at the public sewer as an end point too, without saying which applies when. Past the cleanout, the code says the District "will maintain" the lower lateral, but for one installed before 1 November 2026 another sentence says the District "may continue" to, and the code does not reconcile the two. So ask the District where your side ends and what it will do for yours. The code also warns that "if a blockage in the lower sewer lateral or receiving main sewer is found to be caused by the property-owner's maintenance activities, lack of maintenance activities, and/or FOG, all district repair, liability and or maintenance costs associated with removal of the blockage will be the responsibility of the property-owner" - clear your own line badly, leave it unmaintained, or send fats, oils and grease (FOG) down it, and the District's bill for clearing its own comes to you.

Assistance programmes

  • West Valley Sanitation District Private Lateral Replacement Program

    A loan, secured on the house, and interest-free: "an interest-free five-year term loan as a lien against your property, maximum amount of $3,500, is available for you as a homeowner to assist in replacing your failing, or failed building upper sewer lateral". Repayment is collected on the property tax bill and the lien released when it is repaid. Against a five-figure lateral replacement, $3,500 is a contribution rather than a solution - but it is interest-free money and the District waives its own permit fees for work done under the programme. The order is the District's and runs one way: application and CCTV, then approval, then thirty days to sign a contractor, then ninety "calendar days from the letter date to complete all the scope of work identified in the construction contractor's bid".

    Narrower than most, and the limits are worth reading before hoping. The District offers it "for homeowners with single family residential properties and limited to only one sewer lateral per property and one property per homeowner for the life of the District's Private Lateral Replacement Program (PLRP)" - so a landlord with several houses can use it once, and a flat or a duplex is outside it altogether. It is for a lateral already in trouble rather than one you want replaced before it fails: the loan assists in "replacing your failing, or failed building upper sewer lateral located on your property that connects to a District sewer main located in the public right-of-way". Money is not guaranteed by qualifying - "funding is available on a first-approved, first-served basis". There are deadlines once you are in: thirty calendar days from being notified of approval "to secure a contract with a construction contractor that meets the District requirements", and a CCTV inspection of the lateral is part of getting there.
