City planning program to inspect homes for sewer system problems

July 3, 2013


Residents in East Lawrence may get an odd knock on their door later this year: A city-hired inspector who wants to look at your sump pump and perhaps even make a video of your home’s sewer pipe.

It is the latest effort by city officials to shore up a leaky sewer system and avoid tens of millions of dollars in improvements down the line.

“This will be a different type of program for us, but we think it will be an important one,” City Manager David Corliss said.

Here’s the problem: When it rains the sewer pipes in the older parts of town allow large amounts of water to seep into the sewer system. That water shows up at the city’s lone sewage treatment plant and puts a strain on the plant’s capacity during wet weather. The Environmental Protection Agency already has put the city on notice that the city may have problems in the future meeting the EPA’s wet weather treatment regulations.

Rather than spend $40 million or more to make improvements at the sewage treatment plant and to pump stations throughout town, the city is looking to spend about half that amount on an eight-year program aimed at reducing the amount of water that seeps into the sewage system in the first place.

“You can either catch it before it gets in there or you can build a system to treat it and get it out,” Mayor Mike Dever said. “I think the way we’re doing this will be a good thing.”

But it is going to involve inspectors entering about 1,500 homes, primarily in East Lawrence. Inspectors will be looking for problems such as sump pumps that drain into the city sewer system, down spouts that drain into the sewer system, exterior stairway drains that flow into the sewer system, faulty sewage service lines and a host of other similar issues.

City officials are working out the details of the program, but Corliss said his recommendation will be that the city create a fund to pay for any improvements needed at a person’s home. Homeowners wouldn’t be responsible for the fixes. For example, in other communities that have done this — Columbia, Mo., and Springfield, Mo., are a couple — cities have contracted with a host of local plumbing companies that create a set price for correcting certain types of problems. An engineer told the city this week that a standard sump pump rerouting, for example, may cost about $2,000.

With prices like that, the project won’t be cheap. City officials are prepared to spend a significant amount to reduce the amount of stormwater entering the sewer system. The city’s wastewater master plan has budgeted about $19 million over eight years to address the infiltration and inflow problem, said Dave Wagner, the city’s director of utilities.

Not all of that $19 million, however, will be spent on repairing the faulty sewer systems of homeowners. A good portion of it will be used to place special liners in the main sewer lines that run across the city. A breakdown on how much money will be spent specifically on addressing problems with private systems versus addressing issues on the public system hasn’t been determined yet.

But city commissioners this week got the ball rolling on the project by approving a $1.2 million contract with TREKK Design Group to design and implement the inspection program, along with other tasks.

TREKK officials are estimating that 1,450 buildings — primarily in the eastern city limits north of 23rd Street, south of 11th Street and east of Haskell Avenue — will need to be inspected. Past testing projects indicate that about 600 houses and buildings will need some sort of repair work.

At times, the testing will be fairly extensive. Inspectors in some cases will use closed circuit television cameras to film the inside of a sewer pipe to determine if there are breaks or leaks.

In addition, TREKK plans to inspect about 500 manholes and do smoke testing on about 100,000 feet of sanitary sewer lines.

Now that the contract has been approved, city officials will start developing a program to reach out to homeowners to begin asking for permission to make inspections on the property.

“We know this is going to take a large outreach effort,” said Mike Lawless, the city’s assistant director of utilities. “We know we can’t just knock on the door and expect to get in on the first try.”

Wagner said he hopes some testing can begin in 2013, but he said the inspections will extend well into 2014. In future years, other areas of town — primarily east of Iowa Street — also may be targeted for the inspections.

City commissioners unanimously approved moving forward with the project, which has a goal of reducing the infiltration and inflow problem by about 35 percent.

The infiltration and inflow project is one of two major sewer system projects underway in the city. Design work also is underway on a $64 million sewage treatment plant south of the Wakarusa River. While this infiltration and inflow project isn't eliminating the need for that plant, it is eliminating the need for some improvements at the city’s other sewage treatment plant along the Kansas River.

Future rate increases will help pay for both projects. Corliss’ recommended 2014 budget calls for about a 5 percent increase in the combined water and sewer bills of Lawrence residents.

Should be real interesting where entire blocks in Brookcreek neighborhood are built on a slab!

There is a document on line entitled, Handbook: Sewer System Infrastructure Analysis and Rehabilitation, which is a 22 year old, peer reviewed EPA study looking into this subject of how to best test and repair sewers, why do it to begin with, the economies of various methods, etc

It would be nice if it were a 2013 updated version,..... but government has been gotten out of your life............or whatever !?

Maybe 25 years ago or so they did a program in Johnson County where that county actually installed a brand new sump pump pit, pump and plumbing into all homes with out a sump pump set up, for no immediate cost ( that cost shows up in the long term rates.....but was still much cheaper than expanding their sewage treatment plant that all would have to be paid for, for having to treat all of that "wet basement" leak in water, that it did treat back then, or might have to treat, from a dry basement, that it was assumed, would leak in the future )

Now, spending $2,000 to disconnect an existing sump pump pit from a buildings city sewer line and piping all of the water straight back to the outside, sounds "a little way pricey", to me !

Must be the same engineer who estimated the new farmland water main work before the bids came in much lower?

As important as the work itself or the money spent or saved, would be to work out the "reasonable security concern issues" that people do and will have, concerning strangers entering their homes, to do these inspections and or repairs .

What have other towns done with security issues ?

George_Brazziler above, expressed some sane thoughts regarding this whole thing, as this is a get home free card, on a homeowners sewer maintanance costs . The homeowner can save thousands that they might have to spend in the future, when things deteriorate on a troubled sewer line, by letting the city check it out and fix it now if need be ....and the public saves the cost of an expensive sewer treatment plant expansion to meet peak rainfall flows of infiltrating water into sewer lines .

Many older sewers are clay tile pipes that break because of ground movement or due to thirsty tree roots that break into them and then expand doing more damages that are costly to fix .

Broken sewers also cause sink holes in yards and under streets .

Water flows out of breaks and carries dirt away as it drains back into the broken pipes causing unseen caverns in yards or under streets that can cave in .

I have seen holes under major six lane streets in KC, that were big enough to swallow a full sized dump truck, that were caused by years and years of a broken buildings sewer line simply carrying away the dirt beneath the roadway .

If you are already having to pay some sewer rooter company to come out every so often to clear your main sewer line of tree roots you ought to be thrilled if the city will fix your problem by repairing your line with out handing you a huge bill that is payable on receipt.

P.S. Nothing in this world is perfect but some things are cheaper imperfections than other things are .

I take it that those of you complaining about the Google ads either missed the story this was comming or you're willing to pay to read LJW online. The realism is online newspapers are losing most of their home delivery subscribers and need to find ways to offer free online service to readers and still survive. The Google questions were the solution for LJW. The alternative is paying for an online subscription.

the little questions are a real pain LJW.

At times, the testing will be fairly extensive. Inspectors in some cases will use closed circuit television cameras to film the inside of a sewer pipe to determine if there are breaks or leaks.

---I say:

we're paying for this video, so run it on cable channel #25 when the city commission is not in session!

even run it live while the cameras are in the hole!

could be exciting live action video! who knows? plus, POV video on helmets of the inspectors as they enter the homes.

Good idea the city is getting ahead of this. A community 2 hours south of Lawrence did not get ahead of the issue and the EPA leveled fines against them. In return the residents of that community now have a 10 dollar EPA fee on their water bill. That community is Parsons. And it is a prime example why getting in front of a EPA warning is a good idea it also shows what happens if you do nothing to fix the problem.

While in the homes how about checking for mold. Some rental properties are subjecting tenants to such an experience...... so I'm told.

Is there a regulation to protect tenants if landlords refuse to correct the situation?

While they are at it , the inspectors should look for drugs, too.


oneeye_wilbur 9 months, 2 weeks ago

I thought the city had been relining the sewer lines the past years?

Also if the city is footing the bill why are we paying more in fees?

Corliss must think we are dumb!

Here's a question. What's up with the questions? Fixing old sewer line is a good idea.

When is the city gonna stop with this garbage? Who sits around and dreams this stuff up?

Gonna have to amend my sign: No solicitors OR inspectors!


George_Braziller 9 months, 2 weeks ago

If they're going to run a camera up the line I say bring it on. It would save me the $340 it's going to cost to see if it's possibly just a bad connection to the main sewer that was recently made or if I'm going to have to spend about $7,000 to have the entire line replaced.

Not exactly comfortable with some random person the city hired, to come poking around my house. Especially with a new baby at home. I'm sure you can figure out if there are any sewage problems, without invading the small amount of privacy we have left.
