University Preparatory Academy ( UPA ) is a charter school located in San Jose, California , United States. Its charter was approved by the Santa Clara Board of Trustees. UPA opened in the fall of 2007 as a middle and high school , offering grades 7–12th. As of 2020, approximately 650 students attend UPA with a 21:1 student-teacher ratio.
64-542: In 2020, UPA was ranked the 120th best high school in the nation and the 13th best in California by U.S. News & World Report . UPA was founded as University Preparatory Academy in 2007. Graduation standards are more rigorous than at other high schools, requiring more AP units than is mandated by California laws. UPA's campus is located near downtown San Jose in the Willow Glen area. It shares its campus with

Adults may be tempted to dispose of toilet paper , wet wipes , diapers , sanitary napkins , tampons , tampon applicators, condoms , and expired medications , even at the risk of causing blockages. The privacy of a toilet offers a clandestine means of removing embarrassing evidence by flushing such things as drug paraphernalia , pregnancy test kits, combined oral contraceptive pill dispensers, and
192-493: A broader term, because it refers to any water after it has been used in a variety of applications. Thus it may also refer to " industrial wastewater ", agricultural wastewater and other flows that are not related to household activities. Blackwater in a sanitation context denotes wastewater from toilets which likely contains pathogens that may spread by the fecal–oral route . Blackwater can contain feces , urine , water and toilet paper from flush toilets . Blackwater
256-478: A building's plumbing either into a sewer , which will carry it elsewhere, or into an onsite sewage facility . Collection of sewage from several households together usually takes places in either sanitary sewers or combined sewers . The former is designed to exclude stormwater flows whereas the latter is designed to also take stormwater. The production of sewage generally corresponds to the water consumption. A range of factors influence water consumption and hence

This tradition involves buying similar, very small, Christmas trees and placing them in the front yard ten feet from the sidewalk with multicolored lights. People and businesses in the neighborhood generally make significant decorations every year, both within the neighborhood and in the Lincoln Avenue business district, drawing visitors from all around
512-559: A dry creek bed, known as the "Dry Creek," and opened up Willow Glen for greater southwest expansion. Willow Glen neighborhoods are almost exclusively composed of custom or semi-custom homes in a diverse range of architectural styles. Many architect-commissioned houses can be seen in the neighborhood, including Victorian, Neoclassical (Queen Anne Cottage and Neocolonial), Colonial Revival, Craftsman, Mission, Prairie, Spanish Eclectic, Eichler Homes , and Tudor. In recent years many smaller houses have been replaced with larger houses. Dancin' on

Students can audition to perform in the theatre productions or apply to be on technical crews or part of the band for musicals. Below is a list of some of UPA's previous shows. University Preparatory Academy holds schoolwide events. Such events include: Willow Glen, San Jose Willow Glen is a district of San Jose , California , in Santa Clara County . Willow Glen
640-748: A flowrate of 190 L per person per day. A United States source published in 1972 estimated that the daily dry weight of solid wastes per capita in sewage is estimated as 20.5 g (0.72 oz) in feces, 43.3 g (1.53 oz) of dissolved solids in urine, 20 g (0.71 oz) of toilet paper, 86.5 g (3.05 oz) of greywater solids, 30 g (1.1 oz) of food solids (if garbage disposal units are used), and varying amounts of dissolved minerals depending upon salinity of local water supplies, volume of water use per capita, and extent of water softener use. Sewage contains urine and feces. The mass of feces varies with dietary fiber intake. An average person produces 128 grams of wet feces per day, or
704-568: A form of final disposal or of treatment, or both. Land disposal alternatives require consideration of land availability, groundwater quality, and possible soil deterioration. Sewage may be discharged to an evaporation or infiltration basin . Groundwater recharge is used to reduce saltwater intrusion , or replenish aquifers used for agricultural irrigation . Treatment is usually required to sustain percolation capacity of infiltration basins, and more extensive treatment may be required for aquifers used as drinking water supplies. Before

#1732802068887768-592: A median dry mass of 29 g/person/day. The median urine generation rate is about 1.42 L/person/day, as was determined by a global literature review. The volume of domestic sewage produced per person (or " per capita ", abbreviated as "cap") varies with the water consumption in the respective locality. A range of factors influence water consumption and hence the sewage flowrates per person. These include: Water availability (the opposite of water scarcity ), water supply options, climate (warmer climates may lead to greater water consumption), community size, economic level of
832-461: A result of past disinfection . Sewage may contain microplastics such as polyethylene and polypropylene beads, or polyester and polyamide fragments from synthetic clothing and bedding fabrics abraded by wear and laundering, or from plastic packaging and plastic-coated paper products disintegrated by lift station pumps. Pharmaceuticals , endocrine disrupting compounds, and hormones may be excreted in urine or feces if not catabolized within
896-702: A treatment plant per day: One peak is at the beginning of the morning and another peak is at the beginning of the evening. With regards to water consumption, a design figure that can be regarded as "world average" is 35–90 L per person per day (data from 1992). The same publication listed the water consumption in China as 80 L per person per day, Africa as 15–35 L per person per day, Eastern Mediterranean in Europe as 40–85 L per person per day and Latin America and Caribbean as 70–190 L per person per day. Even inside
960-623: A variety of techniques. Traditional techniques involve filtering, staining, and examining samples under a microscope. Much more sensitive and specific testing can be accomplished with DNA sequencing , such as when looking for rare organisms, attempting eradication , testing specifically for drug-resistant strains, or discovering new species. Sequencing DNA from an environmental sample is known as metagenomics . Sewage has also been analyzed to determine relative rates of use of prescription and illegal drugs among municipal populations. General socioeconomic demographics may be inferred as well. Sewage
1024-439: Is a type of wastewater that is produced by a community of people. It is typically transported through a sewer system . Sewage consists of wastewater discharged from residences and from commercial, institutional and public facilities that exist in the locality. Sub-types of sewage are greywater (from sinks, bathtubs, showers, dishwashers, and clothes washers) and blackwater (the water used to flush toilets , combined with
1088-444: Is almost universally accepted as the community's northern border. The Guadalupe River was the original eastern border of Willow Glen during its time as a municipality. The Los Gatos Creek originally served as a natural western end for the community, until 1866, when extreme flooding of the creek caused it to naturally cut a new channel running far west around what was traditionally considered Willow Glen. The reshaped creek left behind
1152-693: Is an order of magnitude estimate rather than an exact percentage because, aside from variation caused by dilution, solids may be defined differently depending upon the mechanism used to separate those solids from the liquid fraction. Sludges of settleable solids removed by settling or suspended solids removed by filtration may contain significant amounts of entrained water, while dried solid material remaining after evaporation eliminates most of that water but includes dissolved minerals not captured by filtration or gravitational separation. The suspended and dissolved solids include organic and inorganic matter plus microorganisms. About one-third of this solid matter
1216-418: Is commonly collected and transported in gravity sewers , either in a sanitary sewer or in a combined sewer . The latter also conveys urban runoff ( stormwater ) which means the sewage gets diluted during rain events. Infiltration is groundwater entering sewer pipes through defective pipes, connections, joints or manholes . Contaminated or saline groundwater may introduce additional pollutants to
1280-454: Is discharged into a water body (river, lakes, sea) or land, its relative impact will depend on the assimilative capacity of the water body or ecosystem . Water bodies have a self-purification capacity, so that the concentration of a pollutant may decrease along the distance from the discharge point. Furthermore, water bodies provide a dilution to the pollutants concentrations discharged, although it does not decrease their mass. In principle,
1344-403: Is discharged untreated, its nitrogen and phosphorus content can lead to pollution of lakes and reservoirs via a process called eutrophication . In raw sewage, nitrogen exists in the two forms of organic nitrogen or ammonia . The ammonia stems from the urea in urine . Urea is rapidly hydrolyzed and therefore not usually found in raw sewage. Total phosphorus is mostly present in sewage in

#17328020688871408-526: Is distinguished from greywater , which comes from sinks, baths, washing machines, and other household appliances apart from toilets. Greywater results from washing food, clothing, dishes, as well as from showering or bathing. Greywater (or grey water, sullage, also spelled gray water in the United States) refers to domestic wastewater generated in households or office buildings from streams without fecal contamination, i.e., all streams except for
1472-553: Is known for its historic downtown, dining and shopping, and is one of the most expensive neighborhoods to live in San Jose. Willow Glen was originally an independent town, until it voted to be annexed by San Jose in 1936. The neighborhood began in the mid-1800s as Rancho de los Coches and Rancho San Juan Bautista , Mexican land grants adjacent to the San Jose pueblo . Don Antonio Suñol , who owned Rancho de los Coches and built
1536-674: Is low, the strength of the sewage (or pollutant concentrations) is much higher than that in the United States where water use per person is high. Household income and diet also plays a role: For example, for the case of Brazil, it has been found that the higher the household income, the higher is the BOD load per person and the lower is the BOD concentration. Typical values for physical–chemical characteristics of raw sewage in developing countries have been published as follows: 180 g/person/d for total solids (or 1100 mg/L when expressed as
1600-698: Is suspended by turbulence , while the remainder is dissolved or colloidal . For the situation in the United States in the 1950s it was estimated that the waste contained in domestic sewage is about half organic and half inorganic . The organic matter in sewage can be classified in terms of form and size: Suspended (particulate) or dissolved (soluble). Secondly, it can be classified in terms of biodegradability : either inert or biodegradable. The organic matter in sewage consists of protein compounds (about 40%), carbohydrates (about 25–50%), oils and grease (about 10%) and urea , surfactants , phenols , pesticides and others (lower quantity). In order to quantify
1664-408: Is typically found in sewage. Pollutants may be toxic or non- biodegradable waste including pharmaceuticals , biocides , heavy metals , radionuclides , or thermal pollution . An industry may treat its wastewater and discharge it into the environment (or even use the treated wastewater for specific applications), or, in case it is located in the urban area, it may discharge the wastewater into
1728-402: Is usually near neutral, and can be in the range of 6.7–8.0. Sewage consists primarily of water and usually contains less than one part of solid matter per thousand parts of water. In other words, one can say that sewage is composed of around 99.9% pure water, and the remaining 0.1% are solids, which can be in the form of either dissolved solids or suspended solids . The thousand-to-one ratio
1792-577: The Roberto-Suñol Adobe , is considered to be the founder of the community. "Willow Glen" was named for the marshy wet area between the Guadalupe River and Los Gatos Creek , which were abundant in willows and cattails, unusual for the rest of the region. By the 1860s the small unincorporated community needed its first school, and Willow Glen Elementary School was founded in 1863 on land donated by Ira Cottle. Much of Willow Glen
1856-480: The United States are estimated as follows: 365 L/person/day (for one person households), 288 L/person/day (two person households), 200 L/person/day (four person households), 189 L/person/day (six person households). This means the overall range for this example would be 189–365 L (42–80 imp gal; 50–96 US gal). Sewage can be monitored for both disease-causing and benign organisms with
1920-589: The anal area in the shower or bath. The overall appearance of sewage is as follows: The temperature tends to be slightly higher than in drinking water but is more stable than the ambient temperature. The color of fresh sewage is slightly grey, whereas older sewage (also called "septic sewage") is dark grey or black. The odor of fresh sewage is "oily" and relatively unpleasant, whereas older sewage has an unpleasant foul odor due to hydrogen sulfide gas and other decomposition by-products. Sewage can have high turbidity from suspended solids. The pH value of sewage
1984-493: The human waste that it flushes away). Sewage also contains soaps and detergents. Food waste may be present from dishwashing , and food quantities may be increased where garbage disposal units are used. In regions where toilet paper is used rather than bidets , that paper is also added to the sewage. Sewage contains macro-pollutants and micro-pollutants, and may also incorporate some municipal solid waste and pollutants from industrial wastewater . Sewage usually travels from

2048-408: The "per person organic matter load" has been found to be approximately 60 gram of BOD per person per day. This is called the population equivalent (PE) and is also used as a comparison parameter to express the strength of industrial wastewater compared to sewage. Values for households in the United States have been published as follows, whereby the estimates are based on the assumption that 25% of

Trees were purchased in bulk from the Knights of Columbus and delivered to participating homes. The Ciminos moved from the area in 1956 and the tradition was continued by Frank Badagliacca Jr. His wife, Dolores Badagliacca, came up with the idea of putting a single white light on
2368-430: The assimilative capacity of the water body. However, this needs to be analyzed very carefully, taking into account the quality of the water in the receiving body before it receives the discharge of sewage, the resulting water quality after the discharge and the impact on the intended water uses after discharge. There are also specific legal requirements in each country. Different countries have different regulations regarding
2432-414: The community, level of industrialization , metering of household consumption, water cost and water pressure. The production of sewage generally corresponds to the water consumption. However water used for landscape irrigation will not enter the sewer system, while groundwater and stormwater may enter the sewer system in addition to sewage. There are usually two peak flowrates of sewage arriving at

The mass load of organic content is calculated as the sewage flowrate multiplied with the concentration of the organic matter in the sewage. Typical values for physical–chemical characteristics of raw sewage is provided further down below. Apart from organic matter, sewage also contains nutrients. The major nutrients of interest are nitrogen and phosphorus . If sewage

The other form is organic phosphorus, where the source is organic compounds to which the organic phosphorus is bound. Human feces in sewage may contain pathogens capable of transmitting diseases. The following four types of pathogens are found in sewage: In most practical cases, pathogenic organisms are not directly investigated in laboratory analyses. An easier way to assess

2688-1025: The form of cysts or oocysts) and helminths (in the form of eggs). In order to quantify the organic matter, indirect methods are commonly used: mainly the Biochemical Oxygen Demand (BOD) and the Chemical Oxygen Demand (COD). Management of sewage includes collection and transport for release into the environment, after a treatment level that is compatible with the local requirements for discharge into water bodies, onto soil or for reuse applications. Disposal options include dilution (self-purification of water bodies, making use of their assimilative capacity if possible), marine outfalls , land disposal and sewage farms . All disposal options may run risks of causing water pollution . Sewage (or domestic wastewater) consists of wastewater discharged from residences and from commercial, institutional and public facilities that exist in
2752-447: The high water table resulted in raw sewage often spilling above-ground from flooded cesspools. Rather than build their own very expensive sewage treatment system, in 1936 Willow Glen's residents opted to be annexed to San Jose and be linked to San Jose's sewage system, the measure passing by a vote of 978 to 871. Willow Glen includes areas within zip code 95125, though not all of the zip code area can actually be considered to be part of
2816-451: The higher the dilution capacity (ratio of volume or flow of the receiving water and volume or flow of sewage discharged), the lower will be the concentration of pollutants in the receiving water, and probably the lower will be the negative impacts. But if the water body already arrives very polluted at the point of discharge, the dilution will be of limited value. In several cases, a community may treat partially its sewage, and still count on
2880-490: The homes have kitchen waste-food grinders (sewage from such households contain more waste): 95 g/person/d for total suspended solids (503 mg/L concentration), 85 g/person/d for BOD (450 mg/L), 198 g/person/d for COD (1050 mg/L), 13.3 g/person/d for the sum of organic nitrogen and ammonia nitrogen (70.4 mg/L), 7.8 g/person/d for ammonia-N (41.2 mg/L) and 3.28 g/person/d for total phosphorus (17.3 mg/L). The concentration values given here are based on
2944-440: The human body. Some residential users tend to pour unwanted liquids like used cooking oil , lubricants , adhesives , paint , solvents , detergents , and disinfectants into their sewer connections. This behavior can result in problems for the treatment plant operation and is thus discouraged. The composition of sewage varies with climate, social and economic situation and population habits. In regions where water use
3008-400: The local area of larger communities. Sewage can be distinguished into "untreated sewage" (also called "raw sewage") and "treated sewage" (also called "effluent" from a sewage treatment plant ). The term "sewage" is nowadays often used interchangeably with "wastewater" – implying "municipal wastewater" – in many textbooks, policy documents and the literature. To be precise, wastewater is
3072-473: The locality. Sewage is a mixture of water (from the community's water supply ), human excreta ( feces and urine ), used water from bathrooms , food preparation wastes, laundry wastewater, and other waste products of normal living. Sewage from municipalities contains wastewater from commercial activities and institutions, e.g. wastewater discharged from restaurants , laundries , hospitals , schools , prisons , offices , stores and establishments serving
3136-541: The neighborhoods, homes, and community of Willow Glen. The highlight is a festive parade that proceeds down Lincoln Avenue. The origins of Founders' Day are not known. Archives of the Willow Glen Resident newspaper indicate it originates from the area's nine years of independence from San Jose between September 8, 1927, and September 4, 1936. Another view is that it celebrates the work of Antonio Suñol who built Laura Ville in 1847. Willow Glen residents have
3200-435: The organic matter content, it is common to use "indirect methods" which are based on the consumption of oxygen to oxidize the organic matter: mainly the Biochemical Oxygen Demand (BOD) and the Chemical Oxygen Demand (COD). These indirect methods are associated with the major impact of the discharge of organic matter into water bodies: the organic matter will be food for microorganisms, whose population will grow, and lead to
3264-458: The packaging for those devices. There may be reluctance to retrieve items like children's toys or toothbrushes which accidentally fall into toilets, and items of clothing may be found in sewage from prisons or other locations where occupants may be careless. Trash and garbage in streets may be carried to combined sewers by stormwater runoff. Sewage contains environmental persistent pharmaceutical pollutants . Trihalomethanes can also be present as

#17328020688873328-434: The presence of fecal contamination is by assessing the most probable numbers of fecal coliforms (called thermotolerant coliforms), especially Escherichia coli . Escherichia coli are intestinal bacteria excreted by all warm blooded animals, including human beings, and thus tracking their presence in sewage is easy, because of their substantially high concentrations (around 10 to 100 million per 100 mL). The ability of

Mixing industrial wastewater with sewage does nothing to reduce the mass of pollutants to be treated, but the volume of sewage lowers the concentration of pollutants unique to industrial wastewater, and the volume of industrial wastewater lowers the concentration of pollutants unique to sewage. When wastewater
3456-498: The sanitary collection system". The "direct inflows" can result in peak sewage flowrates similar to combined sewers during wet weather events. Sewage from communities with industrial facilities may include some industrial wastewater , generated by industrial processes such as the production or manufacture of goods. Volumes of industrial wastewater vary widely with the type of industry. Industrial wastewater may contain very different pollutants at much higher concentrations than what
3520-402: The sewage flowrates per person. These include: Water availability (the opposite of water scarcity ), water supply options, climate (warmer climates may lead to greater water consumption), community size, economic level of the community, level of industrialization , metering of household consumption, water cost and water pressure. The main parameters in sewage that are measured to assess
3584-404: The sewage strength or quality as well as treatment options include: solids, indicators of organic matter, nitrogen, phosphorus, and indicators of fecal contamination. These can be considered to be the main macro-pollutants in sewage. Sewage contains pathogens which stem from fecal matter . The following four types of pathogens are found in sewage: pathogenic bacteria , viruses , protozoa (in
3648-404: The sewage. The amount of such infiltrated water depends on several parameters, such as the length of the collection network, pipeline diameters, drainage area, soil type, water table depth, topography and number of connections per unit area. Infiltration is increased by poor construction procedures, and tends to increase with the age of the sewer. The amount of infiltration varies with the depth of
3712-582: The sewer in comparison to the local groundwater table . Older sewer systems that are in need of rehabilitation may also exfiltrate sewage into groundwater from the leaking sewer joints and service connections. This can lead to groundwater pollution . Combined sewers are designed to transport sewage and stormwater together. This means that sewage becomes diluted during rain events. There are other types of inflow that also dilute sewage, e.g. "water discharged from cellar and foundation drains, cooling-water discharges, and any direct stormwater runoff connections to
3776-563: The specifications of the quality of the sewage being discharged and the quality to be maintained in the receiving water body. The combination of treatment and disposal must comply with existing local regulations. The assimilative capacity depends – among several factors – on the ability of the receiving water to sustain dissolved oxygen concentrations necessary to support organisms catabolizing organic waste. For example, fish may die if dissolved oxygen levels are depressed below 5 mg/L. Application of sewage to land can be considered as

Willow Glen continued as an unincorporated community until the 1920s, when the City of San Jose ordered the Southern Pacific Railroad to re-route the Southern Pacific Railroad trunk line which at that time was going down Fourth Street. The Southern Pacific then proposed to re-route down Lincoln Avenue. In order to forestall that attempt, Willow Glen

As greywater contains fewer pathogens than blackwater , it is generally safer to handle and easier to treat and reuse onsite for toilet flushing , landscape or crop irrigation , and other non- potable uses. Greywater may still have some pathogen content from laundering soiled clothing or cleaning

The railroad was instead re-routed to its current route through a then-unincorporated area now known as North Willow Glen, where its principal user is now Caltrain . Being a city, however, required thinking about issues such as sewage. Willow Glen had no sewer system – individual homes had their own cesspools or septic systems . Because the area was marshy before being drained for Willow Glen,

In 1860, Lewis dug the channel between Willow Street and Curtner Avenue that carries the Guadalupe River to this day. That channel effectively drained the marsh and opened Willow Glen for farming. By the late 1800s, Willow Glen was generally considered one of the most prized locations in all of the Santa Clara Valley for raising wheat, barley, hay, tobacco and hops. By 1880, plots of Willow Glen farmland were priced nearly 10 times higher than similar plots in
