  2. Simplified sewerage - Wikipedia

    en.wikipedia.org/wiki/Simplified_sewerage

    Simplified sewerage, also called small-bore sewerage, is a sewer system that collects all household wastewater (blackwater and greywater) in small-diameter pipes laid at fairly flat gradients. Simplified sewers are laid in the front yard or under the pavement (sidewalk) or - if feasible - inside the back yard, rather than in the centre of the ...

  4. Zero liquid discharge - Wikipedia

    en.wikipedia.org/wiki/Zero_Liquid_Discharge

    Zero Liquid Discharge (ZLD) is a classification of water treatment processes intended to reduce wastewater efficiently and produce clean water that is suitable for reuse (e.g., irrigation). ZLD systems employ wastewater treatment technologies and desalination to purify and recycle virtually all wastewater received. [1] [2]

  5. Aerobic treatment system - Wikipedia

    en.wikipedia.org/wiki/Aerobic_treatment_system

    The aeration stage and the disinfecting stage are the primary differences from a traditional septic system; in fact, an aerobic treatment system can be used as a secondary treatment for septic tank effluent. [1] These stages increase the initial cost of the aerobic system, and also the maintenance requirements over the passive septic system.

  6. Industrial wastewater treatment - Wikipedia

    en.wikipedia.org/.../Industrial_wastewater_treatment

    Brine treatment systems are typically optimized to either reduce the volume of the final discharge for more economic disposal (as disposal costs are often based on volume) or maximize the recovery of fresh water or salts. Brine treatment systems may also be optimized to reduce electricity consumption, chemical usage, or physical footprint.

  7. Levelized cost of water - Wikipedia

    en.wikipedia.org/wiki/Levelized_cost_of_water

    The levelized cost of water (LCOW or LCW) is the "cost per unit volume of product water produced by a water treatment process or service".It is a measure of efficiency, with lower values representing more efficient methods.
