46-721: A few of these tanks are still in service. The Indus Valley civilization (3000–1500 BC) made use of granaries and water tanks. Medieval castles needed water tanks for the defenders to withstand a siege. A wooden water tank found at the Año Nuevo State Reserve (California) was restored to functionality after being found completely overgrown with ivy. It had been built in 1884. Chemical contact tank of FDA and NSF polyethylene construction, allows for retention time for chemical treatment chemicals to "contact" (chemically treat) with product water. Ground water tank , made of lined carbon steel , may receive water from

69-438: A low center of gravity helping to maintain equilibrium for the transport vehicle, trailer or truck. A Hydro-pneumatic tank is typically a horizontal pressurized storage tank. Pressurizing this reservoir of water creates a surge free delivery of stored water into the distribution system. Glass-reinforced plastic (GRP) tanks/vessels are used to store liquids underground. By design a water tank or container should do no harm to

92-654: A non-intrusive means to inspect water tanks, allowing for detailed examination without direct human entry, thereby increasing operational safety and efficiency. Thermal imaging, on the other hand, is particularly effective in low-visibility and harsh environments, as it facilitates the identification of temperature anomalies that may indicate leaks, weaknesses, or other faults within the tank structure. This application of thermal imaging in structural health monitoring has been substantiated in recent studies,. Together, these technologies enable comprehensive diagnostics that surpass traditional inspection methods, ensuring water tanks meet

115-448: A planetarium projector and dome that has become a popular educational tool for the new observatory. Visitors attending a star party can see a short basic planetarium program on the night sky, and step directly outside and look up (or through a telescope) to see what was just shown to them inside. This is especially useful on cloudy nights, along with the classroom astronomy displays, AV presentations, and computer projected lectures. Despite

138-500: A variety of technology, beginning with pH strips and going to more sophisticated pH monitors, indicate pH which when acidic or caustic, some with output communication capabilities. Most of the algae growth occurs at an optimum pH,  between 8.2 - 8.7. pH level that is neutral or lower can help to reduce the growth of algae. Potential algaecide , shock product will help to clean swimming pools or water tanks from algae. In this process no need to use vacuum cleaner to remove algae. There

161-729: A water well or from surface water, allowing a large volume of water to be placed in inventory and used during peak demand cycles. An elevated water tank , also known as a water tower, will create a pressure at the ground-level outlet of 1 kPa per 10.2 centimetres (4.0 in) or 1 psi per 2.31 feet (0.70 m) of elevation. Thus a tank elevated to 20 metres creates about 200 kPa and a tank elevated to 70 feet creates about 30 psi of discharge pressure, sufficient for most domestic and industrial requirements. Vertical cylindrical dome top tanks may hold from 200 litres or fifty gallons to several million gallons. Horizontal cylindrical tanks are typically used for transport because their low-profile creates

184-882: Is a container for storing water , for many applications, drinking water, irrigation, fire suppression, farming, both for plants and livestock, chemical manufacturing, food preparation as well as many other uses. Water tank parameters include the general design of the tank, and choice of construction materials, linings. Various materials are used for making a water tank: plastics ( polyethylene , polypropylene ), fiberglass , concrete, stone, steel (welded or bolted, carbon, or stainless). Earthen pots, such as matki used in South Asia, can also be used for water storage. Water tanks are an efficient way to help developing countries to store clean water. Throughout history, wood, ceramic and stone tanks have been used as water tanks. These containers were all naturally occurring and some man made and

207-404: Is desirable that water tanks be cleaned annually to reduce delivery of algae, bacteria and viruses to people or animals. A safety based news article linked copper poisoning as originating from a plastic tank. The article indicated that rainwater was collected and stored in a plastic tank and that the tank did nothing to mitigate the low pH. The water was then brought into homes with copper piping,

The AAAP has been promoting popular astronomy in Western Pennsylvania for 75 years and

253-543: Is home to two permanent telescopes, including the Brashear 11-inch refractor. The Wagman Observatory hill, located in the northeast corner of Deer Lakes Park at 40°37′34″N 79°48′44″W  /  40.62611°N 79.81222°W  / 40.62611; -79.81222 , is an ideal location for an astronomical facility. At 1340 feet elevation, it is one of the highest points in Allegheny County , and one of

The Mingo Creek Park Observatory is owned and operated by the AAAP. The observatory was built in the spring/summer of 2004, and officially dedicated in August 2005. It has become

299-476: Is no causative link between the plastic tank and copper poisoning, a solution to the problem is to monitor stored rainwater with pH indicators and add appropriate treatment materials. Recent advancements in water tank inspection and maintenance have significantly enhanced system safety and longevity. Key among these technologies are remotely operated vehicles (ROVs) and thermal imaging, which have become instrumental in early detection of potential issues. ROVs offer

322-737: Is one of the larger astronomy clubs in the nation, with over 500 members. During monthly meetings, upcoming celestial events such as meteor showers , comets , occultations , and planetary alignments are announced, and observations and techniques are shared so that all members may benefit from the experiences. Each meeting also features a special speaker, sometimes an AAAP member, as well as outside experts from various fields. Past speakers have presented topics including meteorite hunting in Antarctica , cosmological modeling using supercomputers , and astrophotography with exotic equipment such as dry-ice cameras. The Nicholas E. Wagman Observatory

345-632: The Observatory, which was originally built in 1987 and expanded in 1995. It is the first and only amateur astronomical observatory in Western Pennsylvania dedicated to public education and enjoyment of the science of astronomy . Members use the facility for recreational and scientific observations, as well as scheduled public viewing evenings known as Star Parties , as well as recreational and scientific observations by members. During these events, visitors can view celestial objects through

368-461: The Wagman observatory being in a remote region of Allegheny County , light pollution remains an issue for astronomers who wish to view the stars. The Greene County Site is not affected as much by light pollution, and is located on a privately-owned cow pasture where AAAP members are permitted to use portable telescopes and equipment for astronomical observations. Water tank A water tank

391-452: The copper was released by the high acid rainwater and caused poisoning in humans. Since the plastic tank is an inert container, it has no effect on the incoming water. Good practice would be to analyze any water source periodically and treat accordingly, in this case, the collected acid rain should be analyzed, and pH adjusted before being brought into a domestic water supply system. The release of copper due to acidic water may be monitored by

414-573: The few such sites not already occupied by a radio mast , microwave relay tower, or water tank . he hill is believed to have been used as a lookout by local Indian tribes such as the Seneca , who used it to watch game and the activities of neighboring tribes. The observatory provides an almost 100% view of the sky. Additionally, its location in a relatively rural country park protects it from most commercial or residential development, which could cause excessive light pollution . The AAAP owns and operates
