Malibu is a beach city in the Santa Monica Mountains region of Los Angeles County, California, situated about 30 miles (48 km) west of Downtown Los Angeles.

The exclusive Malibu Colony has been historically home to Hollywood celebrities. People in the entertainment industry and other affluent residents live throughout the city, yet many residents are middle class. Most Malibu residents live from a half-mile to within a few hundred yards of Pacific Coast Highway, which traverses the city, with some residents living up to one mile away from the beach up narrow canyons.

Santa Monica Bay is a bight of the Pacific Ocean in Southern California, United States. Its boundaries are slightly ambiguous, but it is generally considered to be the part of the Pacific within an imaginary line drawn between Point Dume, in Malibu, and the Palos Verdes Peninsula. Its eastern shore forms the western boundary of the Los Angeles Westside and South Bay regions. Although it was fed by the Los Angeles River until the river's catastrophic change of course in 1825, the only stream of any size now flowing into it is Ballona Creek. Smaller waterways draining into the bay include Malibu Creek, Topanga Creek, and Santa Monica Creek.
A garbage disposal unit is a device, usually electrically powered, installed under a kitchen sink between the sink's drain and the trap. The disposal unit shreds food waste into pieces small enough—generally less than 2 mm (0.079 in) in diameter—to pass through plumbing.

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.
Emma Wood State Beach is a California State Beach in Ventura, California. It is located on the Santa Barbara Channel on the west side of the Ventura River estuary and south of the railroad tracks of the Coast Line and the US Highway 101 freeway.
A combined sewer is a type of gravity sewer with a system of pipes, tunnels, pump stations etc. to transport sewage and urban runoff together to a sewage treatment plant or disposal site. This means that during rain events, the sewage gets diluted, resulting in higher flowrates at the treatment site. Uncontaminated stormwater simply dilutes sewage, but runoff may dissolve or suspend virtually anything it contacts on roofs, streets, and storage yards. As rainfall travels over roofs and the ground, it may pick up various contaminants including soil particles and other sediment, heavy metals, organic compounds, animal waste, and oil and grease. Combined sewers may also receive dry weather drainage from landscape irrigation, construction dewatering, and washing buildings and sidewalks.
Moon Island is an island in Quincy Bay, in the middle of Boston Harbor, Massachusetts. It is the location of the Boston Fire Department Training Academy, and Boston Police Department shooting range.

Aliso Creek is a 19.8-mile (31.9 km)-long, mostly urban stream in south Orange County, California.

A marine outfall is a pipeline or tunnel that discharges municipal or industrial wastewater, stormwater, combined sewer overflows (CSOs), cooling water, or brine effluents from water desalination plants to the sea. Usually they discharge under the sea's surface. In the case of municipal wastewater, effluent is often being discharged after having undergone no or only primary treatment, with the intention of using the assimilative capacity of the sea for further treatment. Submarine outfalls are common throughout the world and probably number in the thousands. The light intensity and salinity in natural sea water disinfects the wastewater to ocean outfall system significantly. More than 200 outfalls alone have been listed in a single international database maintained by the Institute for Hydromechanics at Karlsruhe University for the International Association of Hydraulic Engineering and Research (IAHR) / International Water Association (IWA) Committee on Marine Outfall Systems.
Infiltration/Inflow (I/I) causes dilution in sanitary sewers. Dilution of sewage decreases the efficiency of treatment, and may cause sewage volumes to exceed design capacity. Although inflow is technically different from infiltration, it may be difficult to determine which is causing dilution problems in inaccessible sewers. The United States Environmental Protection Agency defines the term infiltration/inflow as combined contributions from both.

The Redondo Beach via Playa del Rey was an interurban railway route of the Pacific Electric. It operated between the Hill Street Terminal and Cliffton, south of Redondo Beach, through the company's Western Division.
The Christchurch Wastewater Treatment Plant (CWTP), also known as the Bromley sewage plant, is the main wastewater treatment plant of Christchurch, New Zealand. It is located in the suburb of Bromley, adjacent to the Avon Heathcote Estuary. Opened in 1962, it replaced an earlier sewage disposal farm that had operated since 1882. In late 2021, two trickling filters burned down and adjacent suburbs have since been subjected to a putrid smell.
