Wawa Dam

Wawa Dam (also known as Montalban Dam) is a gravity dam constructed over the Marikina River in the municipality of Rodriguez in Rizal province, Philippines. The slightly arched dam is situated in the 360-metre (1,180 ft) high Montalban Gorge or Wawa Gorge, a water gap in the Sierra Madre Mountains, east of Manila. It was built in 1909 during the American colonial era to provide the water needs for Manila. It used to be the only source of water for Manila until Angat Dam was built and Wawa was abandoned. Due to insufficiency of water supply for Metro Manila, there was a strong clamor to reuse the dam.

Dam

A dam is a barrier that impounds water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for such activities as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions.

The word dam can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities.

History

Ancient dams

Early dam building took place in Mesopotamia and the Middle East. Dams were used to control the water level, for Mesopotamia's weather affected the Tigris and Euphrates rivers, and could be quite unpredictable.

The earliest known dam is the Jawa Dam in Jordan, 100 kilometres (62 mi) northeast of the capital Amman. This gravity dam featured an originally 9-metre-high (30 ft) and 1 m-wide (3.3 ft) stone wall, supported by a 50 m-wide (160 ft) earth rampart. The structure is dated to 3000 BC.

Wawa Inc.

Wawa Inc. is a chain of convenience store/gas stations located along the East Coast of the United States. It operates in Pennsylvania, New Jersey, Delaware, Maryland, Virginia, and Florida. The company's corporate headquarters is located in the Wawa area of Chester Heights, Pennsylvania in Greater Philadelphia. As of 2008, Wawa was the largest convenience store chain in Greater Philadelphia, and it is also the third largest retailer of food in Greater Philadelphia, after ACME Markets and ShopRite.

History

The Wawa business began in 1803 as an iron foundry. In 1890, George Wood, a businessperson from New Jersey, moved to Delaware County, Pennsylvania; it was here that he began the Wawa Dairy Farm. Wood imported cows from the British island of Guernsey, and bought 1,000 acres (400 ha) of land in the Chester Heights area; the corporate headquarters would later be renamed Wawa. Since pasteurization was not yet available, many children faced sickness from consuming raw milk. Wood arranged for doctors to certify his milk was sanitary and safe for consumption, which convinced many consumers to buy the product. The strategy worked, and allowed the Wawa dairy to grow. Demand for dairy products grew rapidly during the 1920s, and so did the company. Wawa began using the slogan, "Buy Health by the Bottle," and served customers in Pennsylvania and New Jersey, delivering milk to customers' homes.

Wawa (SEPTA station)

Wawa is an abandoned train station adjacent to U.S. Route 1 in Chester Heights, Pennsylvania. The station was a stop on the Pennsylvania Railroad's West Chester Branch (originally called the West Chester and Philadelphia Railroad). It later became a part of SEPTA's R3 West Chester line.

The station, and all of those west of Elwyn, was closed in September 1986, due to deteriorating track conditions and Chester County's desire to expand facilities at Exton Station on SEPTA's Paoli/Thorndale Line. Service was "temporarily suspended" at that time, with substitute bus service provided. Wawa Station still appears in publicly posted tariffs.

History

The West Chester and Philadelphia Railroad (WC&P) began constructing its rail line from Philadelphia in 1852 and reached Wawa in 1857. The remainder of the line to West Chester was completed in 1858. The WC&P merged with the P&BC in 1881, and both were controlled by the Pennsylvania Railroad.

Wawa Station was originally known as the Baltimore Central Junction Station, being the northern terminus of the Philadelphia and Baltimore Central Railroad (P&BC), later called the Octoraro Branch. Wawa Station was demolished shortly after service ended. Some concrete foundations remain, as do the concrete curb for the platform edge, and the pedestrian tunnel under the track.
