This incident brought into sharp focus the problems that have plagued Fern Meadow residents since they started moving in four years ago. Drainage system problems, flooding, and construction issues ...
A French drain, PVC pipe, or other drainage system is installed in the newly made channel. The installed drain is covered with new cement. The installed drain is covered with new cement. The drainage system collects any water entering the basement and drains it to an internally placed sump pump system, which will then pump the water out of the ...
For such drainage systems to work properly it is crucial that neutral air pressure be maintained within all lines, allowing free gravity flow of water and sewage down drains and through waste pipes. It is critical that a sufficient "pitch" (downward slope) be maintained throughout the drain pipes to keep liquids and entrained solids flowing ...
Compared with concrete or wood, a stainless steel gutter will undergo non-negligible cycles of thermal expansion and contraction as the temperature changes; if allowance for this movement is not made during installation, there will be a potential for deformation of the gutter, which may lead to improper drainage of the gutter system.
Sewerage (or sewage system) is the infrastructure that conveys sewage or surface runoff (stormwater, meltwater, rainwater) using sewers. It encompasses components such as receiving drains , manholes , pumping stations , storm overflows, and screening chambers of the combined sewer or sanitary sewer .
Permeable paving systems, especially those with porous surfaces, require maintenance in order to keep the pores clear of fine aggregates as to not hinder the systems ability to infiltrate stormwater. The frequency of cleaning is again dependent on many site specific factors, such as runoff volume, neighboring sites and climate.

Drainage systems reduce the water level inside a potentially unstable hillside, which leads to reduction in pore water pressures in the ground and an increase in the shear strength within the slope. The reduction in pore pressure by drainage can be achieved by shallow and/or deep drains, depending on hillside morphology, the kinematics of ...
