Alhambra’s Sewer Rules

Who Is Responsible for an Alhambra Sewer Lateral?

The owner of the property it serves, from the house all the way out to the city’s main. Alhambra’s 2025 sewer system management plan states that the city owns and operates no part of the private service laterals, and that property owners must maintain the entire length of theirs, every repair included, from the building to the connection with the city’s main line. The municipal code says the same thing in older language. It defines the house connection sewer as the horizontal piping that begins 24 inches outside the building and runs to its connection with the public sewer, and it requires the owner of the property served to keep it safe and sanitary. The stretch under the parkway, the sidewalk and the street is the owner’s as well.

The mains belong to the city, which owns its sanitary sewer system and runs it through the Utilities and Public Works Department: about 128.5 miles of gravity main between 4 and 36 inches in diameter, roughly 2,800 manholes and seven lift stations. City crews clean the mains with high-pressure jetting and aim to run a camera through the whole gravity system every three years. Alhambra is not served by the county’s Consolidated Sewer Maintenance District. From the city’s mains, wastewater flows into trunk sewers of the Los Angeles County Sanitation Districts that cross Alhambra; County Sanitation District No. 2, which takes in Alhambra, is one of the districts in their Joint Outfall System.

What the City’s Sewer Code Asks of Owners

• Replace a section, rebuild the stretch. If any part of an existing lateral between the lot line and the curb has to be replaced, the code requires that entire stretch to meet the standard for a new connection, and the same applies to the stretch between the curb and the main.

• Street trees. Public Works may remove a tree in the street or parkway that endangers a sewer lateral. If the lateral itself does not resist roots, the city can put off removing the tree until the owner replaces that lateral, at the owner’s own cost, with one that does.

• Backwater valves for low fixtures. Any plumbing fixture that sits below the level of the curb or the property line needs an approved backwater valve or trap between it and the public sewer, kept accessible in a box, and only those low fixtures may drain through it.

• Rain stays out of the sewer. Roof drains and yard drains may not be connected to the public sewer, and a new connection to a city sewer needs a permit from the Director of Public Works.

Digging in the Street

Any excavation in a public street, alley or sidewalk needs a written excavation permit from the Director of Public Works, applied for through the city’s permit portal, and the applicant has to show that it is the property owner or a licensed contractor holding a contract with the owner. The city sets the permit fees and insurance requirements, and the code does not name a particular license class.

Our own part of the job looks like this. We clear Alhambra laterals all the way to the city main. For a repair we turn to the trenchless methods first, and we dig only when the condition of the pipe rules them out. When a repair runs under the street, we handle that section as well, under the excavation permit Public Works issues, and finish the line at the main.

If Sewage Backs Up in Alhambra

• Stop using water. Every sink, toilet, shower and washing machine in the house drains into the same lateral, so each one you use adds to the backup.

• Look at the street. Sewage rising out of a manhole or running down the gutter points to a city main. Report it to the Utilities Customer Service Center at (626) 570-5061, open Monday through Thursday, and at other times to the police department’s non-emergency line, (626) 570-5151; the city’s sewer plan routes after-hours sewer calls through police dispatch to its on-call crew.

• Street clear, house backing up? Then the stoppage is usually in your own lateral, and that is a call to us. If the house has a cleanout, we clear the line from there; if it has none, we go in through the roof vent or through a toilet lifted off the floor, and we can add a cleanout once the line is running.

Alhambra’s Water

Where Does Alhambra’s Water Come From?

Almost everywhere in Alhambra, from the city itself. The Utilities Department runs its own water system, with about 18,000 service connections and about 83,000 customers by its count. Its report on 2025 says about 70 percent of the supply is groundwater pumped from the basin beneath the San Gabriel Valley and the other 30 percent is surface water bought through a Metropolitan Water District connection. The system has eight working wells, six reservoir sites holding 27.53 million gallons, 27 miles of transmission main and 128 miles of distribution main, and a water treatment plant, built in 2008, that filters and disinfects an average of 1.8 million gallons a day. On Los Angeles County’s water purveyor map, sampled at more than 800 points inside the city, nearly every point lies in the city’s own service area. A few blocks along the eastern and northern edges show other suppliers, including San Gabriel County Water District, Golden State Water and California American Water. Those lines are approximate, so your water bill is the final word.

The city’s water quality report on 2025 gives total hardness averaging 240 parts per million in its groundwater, in a range of 160 to 290, and 234 in the imported supply, in a range of 189 to 280. Those are the city’s figures for its own system.

The Meter, the Valves and Who Fixes What

Under the municipal code, the city’s responsibility ends at the water meter, and only city water crews may install the pipe between the main and the meter. The valve on that stretch belongs to the city, nobody else may turn it except in an emergency, and the department operates it on request at no charge for ordinary use. The same section requires every customer to install, at their own expense, a shutoff valve inside the property line where it can be reached in an emergency. If yours is buried, seized or missing, we replace it with a working emergency shutoff valve. A leak at the meter or a break in the street goes to the Utilities Customer Service Center at (626) 570-5061. If the meter keeps moving with every fixture off and nothing looks wet, call us to find the leak on your side.

Additional Information

In Alhambra, does the owner or the plumber take out the permit?

Either one, when you own the property. The Building Division at City Hall, 111 South First Street, issues the permits, and the city requires one for plumbing work such as piping, repiping and new or replacement fixtures. The permit counter is open Monday through Thursday, and applications and inspection requests go through the city’s permit portal. The Building Division’s own page says permits go only to properly licensed contractors and to people exempt from the state’s contractor license law under section 7044 of the Business and Professions Code, the owner-builder exemption. An owner who takes out the permit signs the city’s owner-builder declaration, which makes the owner the responsible party of record, along with a workers’ compensation declaration. So if the property is yours, we can pull the permit for you, or you can pull it yourself if you prefer.

What plumbing code is in force in Alhambra?

The city adopts Los Angeles County’s plumbing code, Title 28, by reference, and keeps its own administrative rules for permits and plan review. Those rules let a few small jobs go ahead without a permit: clearing a stoppage; stopping a leak when no pipe, valve or fixture is replaced; changing a household toilet, bathroom sink, tub or kitchen sink when the waste and vent piping stays; and hooking an appliance to an already permitted gas shutoff valve with a flexible connector. A search of the municipal code finds no earthquake gas valve requirement.
