The right solution for draining areas in yards prone to flooding, the Flo-Well Dry Well System is installed underground to collect, temporarily store, and slowly release excess water into the ground. The gravel-free interior provides 250% more detention volume than comparable sized gravel dry wells. Traditionally a dry well is an underground hole filled with heavy …
For a rough estimate you can plan on spending $500 to $2,500 to install a greywater system in your home. Most of the cost will be labor as the materials are cheap, but the labor can be expensive. Often it requires a plumber which can run between $50-$150 per hour and then someone to run ditches to your beds which can cost between $20-$75 …
discharge from impervious surfaces such as roofs, driveways, sidewalks, parking lots and compacted lawns. They are used to collect stormwater and filter it through a mixture of soil, sand and/or gravel. The designs of bioretention practices mimic volume reduction and pollutant removal mechanisms that work in natural systems.

Sewage Ejector Pump. One way transport water softener discharge up higher elevations is using a sewage ejector pump. A sewage ejector is attached to the sewage system through a vent that blocks any raw sewage from streaming back into your drain line and vents any gases that are produced within the piping.
Sand or gravel filters provide additional treatment as part of a drain field. Effluent is moved to the top of a bed of sand or fine gravel. The liquid at the bottom of the bed then moves to a drain field, or may be recirculated before moving to the drain field. Besides sand, or peat may be used. Mounds. A mound system is used in high water ...
Chapter 7.4 - Gravel Wetlands The subsurface gravel wetland is designed as a system with two horizontal flow-through treatment cells and a forebay in series and where stormwater passes through a saturated gravel substrate that acts as a natural microbial habitat capable of denitrification (i.e., conversion of nitrate to nitrogen gas).

Washing and classifying of aggregate can be considered in two parts, depending on the size range of material. Coarse material: Generally above 3/8 in. (sometimes split at 1/4 in. or #4 mesh). In the washing process it usually is desired to remove foreign, objectionable material, including fine particles.
An important condition of discharging into the water system is that the banks and bed of receiving channels should not be damaged. We've seen the East West Rail Alliance place their dewatering filter bags on a makeshift bed of gravel to slow the discharge down and reduce scour in the channel.

Aboveground Extension Pipe: The easiest solution is to attach an extension pipe or hose to your AC drain, then extend it downhill away from the house or into a thirsty flower bed. Underground Drain Pipe: To hide the drain pipe, run the condensation drain into a buried drainage line, which can then be routed downhill and away from the yard.
