How does drip irrigation work?
Drip irrigation systems apply treated effluent to soil slowly and uniformly through a network of flexible, narrow plastic, polyethylene, or polyvinylchloride (PVC) tubing placed at shallow depths of usually 6-12 inches in the plant root zone. The effluent is pumped through the tubing under pressure but drips slowly from a series of evenly spaced openings in the tubing called emitters. Wastewater must be pretreated (septic tank or aerobic unit) and filtered prior to subsurface disposal via drip irrigation. This is because small solids can clog the tubing and emitters. One advantage of a drip irrigation system is minimal site disturbance because the flexible tubing can be placed around trees and shrubs.
How does an alternating drainfield work?
Alternating drainfields utilize the trench system dispersal option. The division of the soil absorption system into one or more active areas allows alternate use of each individual section over extended periods of time. Usually, alternating fields consist of two fields, each sized anywhere from 50-100% of the total soil absorption area required to effectively treat the wastewater. Flow to the fields are manually switched once or twice a year, often through a pull gate mechanism as shown in the graphic below. This practice extends the overall life of the soil absorption field by allowing the part of the system not receiving the pretreated effluent to “rest.” A resting period allows the infiltrative surface to rejuvenate naturally through biodegradation of the clogging mat.
What is an evapotranspiration system?
Evapotranspiration (ET) systems are ideal in locations where the annual evaporation rate exceeds the annual precipitation rate. The effluent flows from the pretreatment unit to the sand bed underlaid with an impermeable liner. Capillary action in the fine sand causes the effluent to rise to the surface and escape through evaporation while at the same time, vegetation transports the wastewater from the root zone to the leaves where it is transpired as a relatively clean condensate. The design allows for complete wastewater evaporation and plant uptake with no discharge. Evapotranspiration-absorption (ETA) systems are similar to ET systems. However these systems are unlined and designed for use where soils are fairly impenetrable, but not entirely so. The ETA system disposes of wastewater in the same evaporation/transpiration manner but also allows effluent to trickle through underlining natural soils.
What is a low pressure system?
Pressure and low pressure pipe (LPP) systems are shallow, dosed soil absorption systems. The effluent from the pretreatment unit flows by gravity to the pump chamber. When a predetermined level within the pump chamber is reached (usually marked by a float control), the pump forces the effluent through the distribution lines under pressure. This allows effluent to be evenly dosed at intervals with dosing frequencies determined by site and soil conditions.
How does a spray irrigation system work?
Spray irrigation systems apply treated effluent aboveground to reclaim wastewater. The area to be irrigated must be vegetated and landscaped to minimize runoff and erosion. The wastewater must be treated to a high enough level to protect public health and reduce odors. For this reason, the wastewater must be disinfected (ozone, UV, or chlorine). After treatment, filtration, and disinfection, a pump equipped with timers sends the wastewater under pressure through the mains and lines of the spray distribution system at preset times and rates.
What is soil absorption?
Soil absorption systems use the natural soil as part of the onsite wastewater system providing both treatment and ultimate dispersal of the water into the ground. Various configurations exist for soil absorption systems using either gravity or pressure distribution to disperse the water throughout the system.
How does pressure assist work?
In a pressure assist system, the wastewater flows by gravity from the pretreatment unit to the pump chamber where it is pumped uphill and dispersed by gravity through the distribution system. Other than the addition of a pump chamber, this type of system operates identically to a conventional trench or bed system.
What is crop residue?

What is top dressing?
If done properly, the technique of “top-dressing,” or adding a thin layer of soil over your lawn, can improve the soil without killing the existing turf. Top-dressing addresses some common lawn problems, including: Low spots due to rotting tree roots, settling after underground pipe or cable installation, or erosion.
How does top dressing help soil?
Top-dressing gradually improves soil over time. As organic matter breaks down, it filters through the existing soil to improve texture and overall health. Top-dressing can: Improve drainage and drought-resistance. Even out the terrain.
