A septic drain field, a septic tank, and associated piping compose a septic system. The drain field typically consists of an arrangement of trenches containing perforated pipes and porous material (often gravel) covered by a layer of soil to prevent animals (and surface runoff) from reaching the wastewater distributed within those trenches.

Recently completed infiltration basin for stormwater collection. An infiltration basin (or recharge basin) is a form of engineered sump [1] or percolation pond [2] that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay.
In-situ leach mining involves pumping of a lixiviant into the ore body via a borehole, which circulates through the porous rock dissolving the ore and is extracted via a second borehole. The lixiviant varies according to the ore deposit: for salt deposits the leachate can be fresh water into which salts can readily dissolve.
Various scales may be used for different drawings in a set. For example, a floor plan may be drawn at 1:50 (1:48 or 1 ⁄ 4 ″ = 1′ 0″) whereas a detailed view may be drawn at 1:25 (1:24 or 1 ⁄ 2 ″ = 1′ 0″). Site plans are often drawn at 1:200 or 1:100. Scale is a nuanced subject in the use of engineering drawings.
A good example of the autoclave leach process can also be found in the metallurgy of zinc. It is best described by the following chemical reaction: [citation needed] 2 ZnS + O 2 + 2 H 2 SO 4 → 2 ZnSO 4 + 2 H 2 O + 2 S. This reaction proceeds at temperatures above the boiling point of water, thus creating a vapour pressure inside the vessel.

A Buchan trap (alternative names: Bristol interceptor, [1] interceptor trap and disconnecting trap) is a device fitted in a domestic sewer pipe to prevent odours entering the pipe from the public sewer [2] and permeating the house, a common problem before individual plumbing fittings were separately trapped.
Toby Fischer lives in South Dakota, where just 27 doctors are certified to prescribe buprenorphine -- a medication that blunts the symptoms of withdrawal from heroin and opioid painkillers. A Huffington Post analysis of government data found nearly half of all counties in America don't have such a certified physician. So every month, Fischer and his mother drive to Colorado to pick up their ...
