Does the buyer or seller pay for the repairs?

In practice the seller. Because they can’t sell to anyone without fixing it. But it’s negotiable.

But the buyer gets the benefit of the repair. I'd probably push for at least a 50:50 split (or, have the line inspected before listing the house for sale, and if it needs repair add that to the asking price).

I use to live on a property in a development. On my property were a pair of big willows. The trees were large and healthy, well over 50' tall. That was strange, because the region is high desert with little water, and I made no effort to irrigate them. One morning in spring, after I'd been living there about 15 years, the neighborhood streets flooded. There were geysers of water shooting up from manholes. Turns out,…

No OP, but likely the easement allowed them to do it. Just like the power company will trim your trees without asking.

Not only trees in cities do that. A lot of clogged home sewers are caused by trees that wanted more to drink. Once the sewer line is fully blocked, they've arrived in paradise. Now there is a constant supply in the permanently filled sewer line.

Or at least, constant supply for the several hours it will take to call a rooter company and clear the drain line. Ironically, the tree would have better results if it only partly blocked the drain. I wonder if trees might ever evolve to strike that kind of balance, or if there's not enough selection pressure for that to happen.

Sure, but it seems like trees are quite dumb, they don't think that much ahead.

The city where I live estimates that we lose somewhere between 25% and 30% of drinkable water to leaky infrastructure. We've had something close to a drought this summer -- unseasonally long periods without rain. You can see the young trees on the streets and trees in the middle of large parks suffer from it - wilted leaves and leaves dropping earlier than usual. BUT, large old trees seem to be thriving - full canopi…

Austin is close to 50% leakage. Now up to 110gal/day per connection in 2024. https://www.kxan.com/investigations/city-of-austin-pipes-lea...

I did some back of the envelope calculations and it looked to me that the leakage would fill Lake Austin from empty to the brim. That’s a lot of water

This is one example of why I've stopped listening to climate change alarmists. Instead of doing the grunt work of local utility maintenance, it's so much easier to blame "climate change". The climate may be changing, but it's a convenient excuses to not do anything.

Another example - in NYC a few years back, several people died when floodwaters entered their basement homes.

Mayor De Blasio: Climate change.

Local resident: you guys didn't clean out the drains, it's all clogged.

Or as Anthropic's Safety team would write: "Trees conspire to take down human race by sabotaging the underground water network."

With a Botany of Desire angle:

Trees have led the humans to channel water and irrigate them so they survive even in dry and isolated soil, and provide shade for urban areas in exchange.

I'm not sure if I understand your logic. People who advocate to stop climate change (alarmists?) literally never use is as a convenient excuse "not to do anything." If you could provide an example I'd be happy to take that statement back.

Instead, the point is that, due to climate change, we're having more and more instances where something as trivial as a clogged drain can lead to people drowning in their basement apartments.

EDIT: On reflection, the so-called "climate change alarmists" who say you should "not do anything" are probably shills for big corporations, who want to save money on risk mitigation by saying there's no point because it's too late to mitigate the risks of climate change.

That’s really high. There’s either a big problem in your city, or they are making generous estimates to justify asking for more capital. 10-15% is more typical. In my region, the street trees are usually getting sewer water. Residential service in older houses are usually clay pipes with lead solder that the tree infiltrates. It’s not a problem until the clay pops and roots clog it. It varies a lot by region and juri…

As others have mentioned here in Austin there are several creek beds that flow beautiful crystal, clear water during the droughts. It's because the pipes leak that much. Treated drinking water as it turns out is quite beautiful flowing down an otherwise dry creek bed.

> Maple trees need to consume around 50 litres of water per day. Since street trees can’t get much of this from rainwater, which falls on concrete and drains into the city’s sewers, Poirier says the most likely explanation is that it is coming from Montreal’s leaky pipes, which lose 500 million litres of water per day. I feel like this is burying the lede. What can be done to reduce leakage?

Seems like a better question is, why didn't we design our urban and suburban hydrology to water those trees , instead of shunting rain to an already overburdened storm system? This…

Because it’s cheaper not to do it.

No: the ditch company had the easement and the right to deal with their ditch and its problems. They dealt with me fairly and covered all the costs: I feel pretty fortunate that no serious damage to my or other peoples property occurred. That part was luck.
