Imhoff tank. a - upper chamber, b-c - outlet for sludge, d - outlet for biogas (would need to be higher), f - lower chamber, g - slot for sludge to pass from the upper to the lower chamber, h - height. The Imhoff tank, named for German engineer Karl Imhoff (1876–1965), is a chamber suitable for the reception and processing of sewage.
Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

English: Diagram of a water distribution system. Inlet water goes through a pumping station. The water is delivered to the top of a water tank. Water pressure created by gravity and delivered to water mains. Water mains are connected to fire hydrants and service lines which are pipes that connect a water main to a building.
The above groundwater flow equations are valid for three dimensional flow. In unconfined aquifers, the solution to the 3D form of the equation is complicated by the presence of a free surface water table boundary condition: in addition to solving for the spatial distribution of heads, the location of this surface is also an unknown. This is a ...
Groundwater models are used in various water management plans for urban areas. As the computations in mathematical groundwater models are based on groundwater flow equations , which are differential equations that can often be solved only by approximate methods using a numerical analysis , these models are also called mathematical, numerical ...
The lower tanks are connected to these ballast tanks by non-return valves. The United States Coast Guard does not allow this design to enter US waters, effectively preventing it from being built. [citation needed] When a lower tank is damaged, the incoming sea water pushes the oil in the damaged tank up into the ballast tank.
The water system was introduced both as a response to several fires which had plagued the village and as an effort to bring modern technology and progress, among other civic concerns. The water tower consists of a steel tank with a hemispherical bottom supported by a steel trestle; the structure is 136.5 feet (41.6 m) tall.
