In 1815, Philadelphia began sourcing its water via the [[Fairmount Water Works]] on the [[Schuylkill River]], the nation's first major urban water supply system. In 1909, the Water Works was decommissioned as the city transitioned to modern [[Sand filter|sand filtration]] methods.<ref>{{cite web |url=http://fairmountworks.com/our-story/ |title=Fairmount Water Works: Our Story |publisher=Fairmount Water Works |access-date=April 24, 2015 }}</ref> [[Philadelphia Water Department]] (PWD) provides [[drinking water]], [[wastewater]] collection, and [[stormwater]] services for Philadelphia, as well as surrounding counties. PWD draws about 57 percent of its drinking water from the [[Delaware River]] and the balance from the Schuylkill River.<ref name="PWD">{{cite web |url=http://www.phila.gov/water/aboutus/Pages/AboutPhiladelphiaWater.aspx |title=About Philadelphia Water |publisher=City of Philadelphia |access-date=April 24, 2015 }}</ref> The city has two filtration plants on the Schuylkill River and one on the Delaware River. The three plants can treat up to 546&nbsp;million gallons of water per day, while the total storage capacity of the combined plant and distribution system exceeds one billion gallons. The wastewater system consists of three water pollution control plants, 21 pumping stations, and about {{convert|3657|mi|km}} of sewers.<ref name="PWD"/>

[[Exelon]] subsidiary [[PECO Energy Company]], founded as the Brush Electric Light Company of Philadelphia in 1881 and renamed Philadelphia Electric Company (PECO) in 1902, provides electricity to about 1.6&nbsp;million customers and more than 500,000 natural gas customers in the southeastern Pennsylvania area including the city of Philadelphia and most of its suburbs.<ref>{{cite web |url=https://www.peco.com/AboutUs/Pages/CompanyInformation.aspx |title=PECO: Company Information |publisher=PECO Energy Company |access-date=January 29, 2017 }}</ref> PECO is the largest electric and natural gas utility in the state with 472 power substations and nearly {{convert|23000|mi|km}} of electric transmission and distribution lines and {{convert|12000|mi|km}} of natural gas transmission, distribution, and service lines.<ref>[https://www.peco.com/SiteCollectionDocuments/PECO_Investing_in_our_Community_Booklet.pdf "PECO_Investing_in_our_Community_Booklet"] {{Webarchive |url=https://web.archive.org/web/20180130204845/https://www.peco.com/SiteCollectionDocuments/PECO_Investing_in_our_Community_Booklet.pdf |date=January 30, 2018 }}. page 2.

====Natural gas====
{{Further|Philadelphia Gas Works}}
[[Philadelphia Gas Works]] (PGW), overseen by the [[Pennsylvania Public Utility Commission]], is the nation's largest municipally-owned natural gas utility. PGW serves over 500,000 homes and businesses in the Philadelphia area.<ref>{{cite web |url=http://www.pgworks.com/residential/about-us/about-pgw |title=PGW: About Us |publisher=Philadelphia Gas Works |access-date=April 24, 2015 |archive-date=April 18, 2015 |archive-url=https://web.archive.org/web/20150418135502/http://www.pgworks.com/residential/about-us/about-pgw |url-status=dead }}</ref> Founded in 1836, the company came under city ownership in 1987 and has been providing the majority of gas distributed within city limits. In 2014, the [[Philadelphia City Council|City Council]] refused to conduct hearings on a $1.86&nbsp;billion sale of PGW, part of a two-year effort that was proposed by the mayor. The refusal led to the prospective buyer terminating its offer.<ref>{{cite news |url=http://articles.philly.com/2014-10-28/news/55525996_1_concentric-energy-advisors-city-council-uil-holdings-corp |title=$1.86B sale of Philadelphia Gas Works is dead |work=The Philadelphia Inquirer |date=October 28, 2014 |access-date=April 24, 2015 |author=Maykuth, Andrew |archive-url=https://web.archive.org/web/20150512113604/http://articles.philly.com/2014-10-28/news/55525996_1_concentric-energy-advisors-city-council-uil-holdings-corp |archive-date=May 12, 2015 |url-status=dead }}</ref><ref>{{cite news |last1=Hepp |first1=Chris |title=PGW deal latest casualty in Philly's Nutter-and-Clarke soap opera |url=http://articles.philly.com/2014-12-08/news/56806983_1_uil-philadelphia-gas-works-community-meeting |access-date=May 25, 2015 |work=The Philadelphia Inquirer |date=December 8, 2014 |archive-url=https://web.archive.org/web/20150516023824/http://articles.philly.com/2014-12-08/news/56806983_1_uil-philadelphia-gas-works-community-meeting |archive-date=May 16, 2015 |url-status=dead }}</ref>

Southeastern Pennsylvania was assigned the [[area code 215|215]] [[area code]] in 1947 when the [[North American Numbering Plan]] of the [[Bell System]] went into effect. The geographic area covered by the code was split nearly in half in 1994 when [[Area codes 610, 484, and 835|area code 610]] was created, with the city and its northern suburbs retaining 215. [[area code overlay|Overlay area code]] 267 was added to the 215 service area in 1997, and 484 was added to the 610 area in 1999. A plan in 2001 to introduce a third overlay code to both service areas, [[area code 445]] to 215 and [[Area codes 610, 484, and 835|area code 835]] to 610, was delayed and later rescinded.<ref>{{cite web |url=http://www.nanpa.com/pdf/PL_332_v1.pdf |title=PA 445 Implementation for 215/267 NPA Rescinded – 445 NPA Code Reclaimed |access-date=January 31, 2007 |archive-date=February 11, 2007 |archive-url=https://web.archive.org/web/20070211153116/http://www.nanpa.com/pdf/PL_332_v1.pdf |url-status=dead}}&nbsp;{{small|(64.5&nbsp;KB) }}</ref> Area code 445 was implemented as an overlay for area codes 215 and 267 starting on February 3, 2018.<ref>{{cite web |url=http://6abc.com/home/445-philadelphia-suburbs-getting-new-area-code/3011823/ |title=445: Philadelphia, suburbs getting new area code (Pennsylvania) |date=January 31, 2018}}&nbsp;{{small|(1.1&nbsp;[[Mebibyte|MiB]]) }}</ref>
