Woodland Is Replacing 70-Year-Old Pipe. Yours Is the Same Age

The City of Woodland is in construction on CIP 25-01, the 2026 Water and Sewer Replacement project, with completion expected this winter. Crews are removing roughly 5,400 feet of failing water distribution line, the kind that runs behind the sidewalk instead of under the street. The city puts the age of that water infrastructure at 59 to 71 years. The sewer pipe under the same blocks runs 70 to 97 years old.

A second project is already designed. CIP 26-02 covers Beamer Street between Elm and East, plus First and Second Streets between Beamer and North. The water mains there are 65 to 85 years old. The sewer pipe is 94 to 126 years old, meaning some of it went into the ground around 1900.

This is the eleventh year of an annual program. Woodland maintains about 300 miles of water main and 200 miles of sewer main, and engineering staff rank streets each year by how often they break and leak. For homeowners on those streets, the work is good news. It is also incomplete news.

Woodland is replacing the public side of the system. The main in the ground and the public portion of the service connection. What happens past that point belongs to the property owner, and it covers two separate lines: the water service that runs from the meter into the house, and the sewer lateral that carries waste from the house out to the city main.

"People watch the backhoe go by and assume they got a new pipe," says Joe Weins, who founded Yolo Plumbing Inc. in Woodland in 2011. "They got a new main. The line from the meter to their water heater is the same line that was put in when the house was built. Nobody replaced that."

The ages line up. If the city rates the main on your block at 70 years old, the private line feeding your house is usually within a few years of the same vintage, installed by the same crews, out of the same material.

When Woodland built its service line inventory for the federal lead rule, staff went through decades of development plans, replacement records, and building permits. The finding on lead was reassuring. The city identified no lead service lines anywhere in the system, which matches the statewide result. The inventory also recorded what customer-owned lines are made of: copper, plastic, and galvanized steel.

Galvanized steel is the one worth paying attention to. It does not pose a lead concern in Woodland, but it corrodes from the inside out. Scale builds on the interior wall, the usable diameter shrinks, and flow drops off slowly enough that most people adjust to it without noticing. Yolo County's hard water speeds that process up.

On the sewer side, older Woodland neighborhoods were built with vitrified clay pipe laid in short sections with joints every few feet. Clay does not rust. It cracks, and it separates at the joints.

"Clay soil here swells when it gets wet and shrinks when it dries out," Weins says. "That moves the pipe. Then you have a gap at a joint, and every mature tree on the block knows exactly where the water is."

Root intrusion through a joint in a clay lateral is one of the most common sewer calls in Woodland and Davis, and it tends to show up right when the rain starts.

Most private-side failures announce themselves well before they become emergencies. On the water line, the signs are pressure that has dropped off over several years, rusty or brown water after the house has sat unused, or a water bill that climbs without any change in habits. A damp spot in the yard between the meter and the house that never quite dries out is a strong signal on its own.

On the sewer side, the pattern to watch for is drains across the house slowing at the same time, gurgling from a tub or floor drain when a toilet flushes, or a backup that clears and then returns a few months later on a predictable schedule. That last one usually means roots rather than grease.

A camera inspection settles the question. A plumber runs a line into the lateral and shows the condition of the pipe, the joints, and any intrusion. For a house built before 1970 that has never had the lateral looked at, that inspection is worth scheduling on its own rather than during a backup.

There is one piece of advice Weins gives that has nothing to do with the condition of the pipe at all.

"If the city has the street open in front of your house, that is the cheapest your side is ever going to be," he says. "The hardest part of replacing a lateral is getting to it. If the trench is already there and the restoration work is already happening, you are in a completely different cost position than you will be in two years when everything is paved back over."

That window is narrow. Once a block is finished and repaved, the next homeowner who needs a lateral replaced pays for the full excavation and the street repair on top of the pipe. Property owners on a scheduled street can contact the city's Public Works Department to confirm the timeline for their block, then have their private line evaluated before crews arrive rather than after they leave.

Timing matters for a second reason. Yolo County gets its water in a concentrated winter stretch rather than spread across the year, which means saturated soil, more ground movement, and more pressure on the joints in an old clay lateral, all arriving in the same few weeks. Fall is the practical window. A camera inspection in October costs the same as one in February and is considerably easier to schedule.

"The calls we hate are the ones that come in at nine at night during the first real storm," Weins says. "Almost every one of those was visible on a camera six months earlier."
