Typical retail price for a domestic drain water heat recovery unit ranges from around $400 to $1,000 Canadian. For a regular household, water heating is usually about 20% of overall energy demand. [2] The energy savings can result in an average payback time for the initial investment of 2–10 years. [citation needed]
KOS+ M openwell submersible pump. Small-scale sewage pumping is normally done by a submersible pump. This became popular in the early 1960s, when a guide rail system was developed to lift the submersible pump out of the pump station for repair, and ended the dirty and sometimes dangerous task of sending people into the sewage or wet pit.

In addition to the Jayco brand, Jayco acquired Starcraft RV in 1991, Entegra Coach in 2008 and Highland Ridge RV in 2014. In 2016, Jayco reached their 1 millionth manufactured RV milestone and the Eagle line celebrated 25 years, becoming the industry's longest-running trailer brand. Jayco was acquired by Thor Industries in July 2016 for $576 ...
With a central water heater of any type, any cold water standing in the pipes between the heater and the point-of-use is dumped down the drain as hot water travels from the heater. This water wastage can be avoided if a recirculator pump is installed, but at the cost of the energy to run the pump, plus the energy to reheat the water ...
Sewage treatment (or domestic wastewater treatment, municipal wastewater 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.

In situations where a downward slope out of a building en route to a treatment system cannot be created, a special collection sump pit and grinding lift "sewage ejector" pump are needed. By contrast, potable water supply systems are pressurized up to 50 pounds per square inch (340 kPa) or more and so do not require a continuous downward slope ...
Most large cities today pipe solid wastes to sewage treatment plants in order to separate and partially purify the water, before emptying into streams or other bodies of water. For potable water use, galvanized iron piping was commonplace in the United States from the late 1800s until around 1960.
Many large cities in the U.S. operate combined sewers, which collect sewage and stormwater runoff in a single pipe system leading to the treatment plant. Combined sewers can cause serious water pollution problems due to combined sewer overflows, which are caused by large variations in flow between dry and wet weather.
