All the poles are in the sidewalk here. Stupid. I don't have to cut lawn around them though, so there's that I guess.
The project hasn't really moved to the actual roadway. There's trenching going on in support of new LNG lines. As well as continued utility pole work. New poles on right. Both efforts result in traffic backups in the area
I'm curious and not being critical - do residences use liquified natural gas in your area? I thought the temperatures and pressures required would prohibit it from residential use. Or am I misunderstanding your abbreviation?
Gas has been there for decades. We're good with propane. It's my understanding that when the gas lines were originally installed, free hookups were available. The previous owner opted to stay with propane, and it's fine with us. Hot water and kitchen cook top uses it.
Showing my ignorance?? When natural gas lines are in place, is not the gas in a liquid state? If it's allowed to change state, then that must happen elsewhere. Maybe, I just learned something!! New England could use more pipelines through the region however, NIMBY prevails.
Depends on type of line 8” ines from Canada are pressurized liquid, most residential lines 1”or so are in gaseous state.. so leaks smell Here being on a nat gas line (if available) are significantly cheapest BTU for heat, hot water, cooking and clothes drying. Cheaper then mini splits for heat and efficient water heaters. when appliances die, (including furnace) gas company offers free install with xx a month on bill which includes cleaning
LNG has to be kept at like minus 250 degrees F. Above that it turns back into NG. LNG is like 600 times less voluminous than NG - hence LNG ships, with the equip to keep it really, really cold. . Some of your NG may have come into Boston via LNG tanker, though. Your street mains may be at a higher pressure-like 15 PSI, then you have that little contraption on the side of your house that reduces it down to about 2PSI. Propane is different and can be turned into a liquid simply by pressurising it. (around 150 PSI but it depends on temperature) Hence you have propane in tanks in a liquid state. It is also quite dense and heavier than air so you have to be real careful with it on boats as any leaks will pool in the bilge. Same with tunnels - any leaks and the propane pools at the lowest spot. Also why you are not supposed to store propane tanks indoors - any leaks will end up on the basement floor, unpressurized, gaseous and invisible. Rather flammable.
Looks like they are setting up to do directional boring...fine if its done correctly, but contractors often cut corners and don't "pothole" (expose) them at every existing utility crossing (like they are required to)...that causes lots of problems, sometimes very big problems! Like here in NEO last week...contractor blew up the whole neighborhood! Twinsburg halts underground utility operations after gas explosion destroys 3 homes: Read the city's full statement 5 Northeast Ohio cities pause directional drilling after gas explosion Even if nothing like that happens, they can still push/shift water service lines, sewer service, gas lines, etc and cause problems that don't show up right away, until down the road, after they're gone...then even though it should be on them to fix, good luck holding the contractor's feet to the fire months (more?) after they're gone. Some cities do better with keeping track of these yahoos than others. But overall, it's been a major problem as this installation method gets more n more popular. Bottom line, if they are getting ready to do directional boring in your neighborhood, and you know where your service lines are, make them pothole (expose) them before drilling!! If you see one of these machines set up down the street from your house, get out there and make sure they have crossed their T's and dotted their I's! Not kidding...screwups with directional boring can be very serious! Cable/internet contractors are notorious for cutting corners with this stuff too!
No water/sewer lines to contend with. They've been using a backhoe to open up trenches over the gas line. Haven't seen anything close to a boring machine that your picture represents. FWIW it's National Grid that's involved.
