Through a series of pumps and electricity, from the USGS Water Science School:
Let’s assume that you get your water from the local water department through pipes buried below the streets. In other words, you don’t have your own well in your back yard. Chances are that you get your water through gravity and pumps. Cities and towns build those big water towers on top of the highest hills and then fill them with water. So even if you live on a hill, there’s a good chance the water tower is higher than your house. Water moves from the tower, due to gravity, and goes down a large pipe from the tower to eventually reach your house.
Although gravity supplies the power to move water from the tower to homes, electricity is needed to run a pump to push water from the source.
In my city, those water pumps use a lot of electricity. It is the second largest city expense, using 5.4 million kWh and costing more than $500K a year. (Energy Action Plan, page 21)

I’ve got two maps for you. The first is the slippy map above from London Town:
I like the…hand-drawn feel of the map. Venues are shown in indicative locations rather than being geographically correct, as the details of London between the venues are missed out. This makes it a very poor map for navigating around London between the venues, but a good graphic illustrating just how many venues in London there are, and how they relate geographically to the major London landmarks. – Mapping London
Second, is the one you would pick up in the London Tube if you were going to the games. Created for the Olympics, the “London Summer 2012” map looks like a pretty cool brochure/souvenir for the games:
The maps feature key landmarks, the locations of Olympics related events (such as London Live) and shops, a selection of interesting museums and also more practical information such as public amenities, police stations and NHS walk in centres. The maps also include 6 discovery trails (round trips) to help explore different areas (such as the City; Spitalfields and Brick Lane; Regent’s Park; and the West End).

A milestone for Twitter today, according to the Paris-based analyst group Semiocast. The social network has now passed the half-billion account mark — specifically 517 million accounts as of July 1, 2012, with 141.8 million of those users in the U.S., still about half as many users as Facebook has but positioning it as the second-biggest social networking site.
And just as most of Twitter’s users are coming from outside the U.S., so are the tweets: the top three cities in terms of tweets, it says, are Jakarta, Tokyo and London.

This has become the world’s five-ring capital, a place where the Olympic flame is more like a raging beach bonfire, a place that increasingly produces more Olympic athletes in more sports on a more regular basis per capita than anywhere else maybe on the planet. The 2012 Summer Games begin Friday in London, and San Diego — a city of 1.3 million, a county of 3.1 million — can claim 80 athletes who either grew up here or currently live and train here.
And that doesn’t include another two dozen rowers who have wintered on Lower Otay Reservoir for the past several years, which would push the number north of 100 — or roughly one in five members of the U.S. Olympic team. San Diego County has roughly one-hundredth of the U.S. population.
Jarred Rome, a discus thrower who moved here in 2003 and like Schmidt is headed to his second Olympics, put it like this: “When you’re around greatness, you become great.”
There are race walkers and kayakers, a fencer, an equestrian dressage rider, a track cyclist who cut her teeth on the oval in Balboa Park. The U.S. women’s field hockey team relocated here in 2008.

Pushing ahead with plans to invest $304 million in Austin, Texas, Apple has secured a deal for three large patches of land adjacent to its existing campus, which — when developed — will expand its presence in the area and result in the creation of more than 3,600 jobs.
The State of Texas offered Apple an investment of $21 million over ten years via its Texas Enterprise Fund (TEF), followed by an $8.6 million grant investment from the City of Austin.
As part of its City deal, Apple would need to invest $56.5 million in new facilities and equipment by the end of 2015, with an additional $226 million investment coming by the end of 2021.

Metros with the Most Construction Permits in 2011
- Houston, TX – 31,271
- Dallas, TX – 18,686
- Washington, DC – 16,501
- New York, NY – 13,973
- Austin, TX – 10,239
- Los Angeles, CA – 9,895
- Phoenix, AZ – 9,081
- Seattle, WA – 8,664
- Atlanta, GA – 8,634
- San Antonio, TX – 7,127
More permits were issued in the Houston metro area than in any other metro, by far. Four of the top ten metros were in Texas. But this list is dominated by large metro areas, and we’d expect bigger areas to have more construction activity. Looking instead at the number of permits issued per 1,000 existing housing units…here are the top metro areas by construction activity:
Most Construction Activity (per 1,000 existing units)
- El Paso, TX – 15.36
- Austin, TX – 14.49
- Raleigh, NC – 13.66
- Houston, TX – 13.55
- Charleston, SC – 12.80
- Dallas, TX – 11.26
- Little Rock, AR – 10.53
- Baton Rouge, LA – 9.51
- Washington, DC – 9.44
- Columbia, SC – 8.74
