Porirua, a city in the Wellington Region of the North Island of New Zealand, is one of the four cities that constitute the Wellington metropolitan area. The name 'Porirua' is a corruption of 'Pari-rua', meaning "the tide sweeping up both reaches". It almost completely surrounds Porirua Harbour at the southern end of the Kāpiti Coast. As of 2023, Porirua has a population of 62,400 people, and is a majority minority city, with 26.5% of its population being primarily Pasifika and 23.0% primarily Māori. Porirua is the only area with city status in New Zealand with a Pasifika plurality.
A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater (sewage) flows for basic sewage treatment. Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate. Septic tank systems are a type of simple onsite sewage facility. They can be used in areas that are not connected to a sewerage system, such as rural areas. The treated liquid effluent is commonly disposed in a septic drain field, which provides further treatment. Nonetheless, groundwater pollution may occur and is a problem.
Wellington Harbour, officially called Wellington Harbour / Port Nicholson, is a large natural harbour on the southern tip of New Zealand's North Island. The harbour entrance is from Cook Strait. Central Wellington is located on parts of the western and southern sides of the harbour, and the suburban area of Lower Hutt is to the north and east.
Te Motu Kairangi / Miramar Peninsula is a large peninsula on the southeastern side of the city of Wellington, New Zealand. It is located at the entrance to Wellington Harbour, in Wellington's eastern suburbs. According to Māori legend, it was formed when the taniwha Whaitaitai beached as he tried to escape the confines of the harbour. It contains the suburbs of Miramar, Seatoun, Strathmore Park, and Karaka Bays.
Biosolids are solid organic matter recovered from a sewage treatment process and used as fertilizer. In the past, it was common for farmers to use animal manure to improve their soil fertility. In the 1920s, the farming community began also to use sewage sludge from local wastewater treatment plants. Scientific research over many years has confirmed that these biosolids contain similar nutrients to those in animal manures. Biosolids that are used as fertilizer in farming are usually treated to help to prevent disease-causing pathogens from spreading to the public. Some sewage sludge can not qualify as biosolids due to persistent, bioaccumulative and toxic chemicals, radionuclides, and heavy metals at levels sufficient to contaminate soil and water when applied to land.
The Hyperion Water Reclamation Plant is a sewage treatment plant in southwest Los Angeles, California, next to Dockweiler State Beach on Santa Monica Bay. The plant is the largest sewage treatment facility in the Los Angeles Metropolitan Area and one of the largest plants in the world. Hyperion is operated by the City of Los Angeles, Department of Public Works, and the Bureau of Sanitation. Hyperion is the largest sewage plant by volume west of the Mississippi River.

The Ashbridges Bay Wastewater Treatment Plant is the city of Toronto's main sewage treatment facility, and the second largest such plant in Canada after Montreal's Jean-R. Marcotte facility. One of four plants that service the city of Toronto, it treats the wastewater produced by some 1.4 million of the city's residents and has a rated capacity of 818,000 cubic metres per day. Until 1999 it was officially known as the Main Treatment Plant. The plant has a 185 m (607 ft) high smokestack which is visible from most parts of the city.
A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of rocks, coke, gravel, slag, polyurethane foam, sphagnum peat moss, ceramic, or plastic media over which sewage or other wastewater flows downward and causes a layer of microbial slime (biofilm) to grow, covering the bed of media. Aerobic conditions are maintained by splashing, diffusion, and either by forced-air flowing through the bed or natural convection of air if the filter medium is porous. The treatment of sewage or other wastewater with trickling filters is among the oldest and most well characterized treatment technologies.
Sewage treatment is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated industrial wastewater. There are a high number of sewage treatment processes to choose from. These can range from decentralized systems to large centralized systems involving a network of pipes and pump stations which convey the sewage to a treatment plant. For cities that have a combined sewer, the sewers will also carry urban runoff (stormwater) to the sewage treatment plant. Sewage treatment often involves two main stages, called primary and secondary treatment, while advanced treatment also incorporates a tertiary treatment stage with polishing processes and nutrient removal. Secondary treatment can reduce organic matter from sewage, using aerobic or anaerobic biological processes. A so-called quarternary treatment step can also be added for the removal of organic micropollutants, such as pharmaceuticals. This has been implemented in full-scale for example in Sweden.
Seaview is an industrial suburb of the city of Lower Hutt, in Wellington, New Zealand. Situated on the eastern coast of the Hutt Valley, the suburb lies between Te Awa Kairangi / the Hutt River and Petone, and the bays of Eastbourne to the south. Seaview is a centre for bulk liquid fuel storage for the lower half of the North Island, and a site for heavy industry. It is also a base for support services for trucks and transportation businesses and the location of the wastewater treatment plant for drainage from the Hutt Valley. Seaview is home to the Port Road Drags, the longest-running street drag races in Australasia.
Awatoto is a coastal suburb area within the city of Napier, Hawke's Bay, New Zealand. It stretches along the coast south of Te Awa and the central city. The northern part of Awatoto is residential, while the southern part is industrial, including heavy industry.
Evans Bay is a large bay at the southern end of Wellington Harbour, New Zealand. Located between the Miramar Peninsula and Hataitai, it was the site of New Zealand's first patent slip and served as Wellington's international flying-boat terminal from 1938 until 1956. It is named after George Samuel Evans, an early Wellington settler.
Blue Plains Advanced Wastewater Treatment Plant in Washington, D.C., is the largest advanced wastewater treatment plant in the world. The facility is operated by the District of Columbia Water and Sewer Authority. The plant opened in 1937 as a primary treatment facility, and advanced treatment capacity was added in the 1970s and 1980s. The effluent that leaves Blue Plains is discharged to the Potomac River and meets some of the most stringent permit limits in the United States.
Takapūneke, with the location also known as Red House Bay, is a former kāinga—an unfortified Māori village—adjacent to present-day Akaroa, New Zealand. Takapūneke was a major trading post for the local iwi (tribe), Ngāi Tahu, as there was safe anchorage for European vessels. The site is of significance to Ngāi Tahu as their tribal chief, Tama-i-hara-nui, was captured here by North Island Ngāti Toa chief Te Rauparaha, and then tortured and killed. The village itself was raided and subject of a massacre, with the events subsequently called the Elizabeth affair. There is a direct link from the massacre in 1830 to the signing of the Treaty of Waitangi in 1840, giving the site a status of national significance.
Water supply and sanitation in the Wellington region involves the provision of the "three waters" – drinking water, stormwater, and wastewater services in the Greater Wellington region.
The San José–Santa Clara Regional Wastewater Facility is a wastewater treatment plant located in the Alviso neighborhood of San Jose, California.
