Cluster/Community Variable
Here is a list of the septic sewer systems, accompanied by the approximate expenses for each type:
- Anaerobic Septic System
Average Cost: $3,000–8,000
Description: The simplest and one of the most popular types of septic systems is anaerobic systems which depend on the bacteria that do not need oxygen to take in wastes. These systems use septic tanks in combination with a drainfield but do not involve the use of any mechanical parts or electric supply which helps keep down costs.
Pros: cheaper initial cost and cost of upkeep.
Cons: Ground conditions have to be favorable for drainage; such systems are not good in regions where the soil is rather poor.
- Chamber Septic System
Average Cost: $5,000 – 12,000
Description: This system substitutes conventional gravel in the drainfield with plastic chambers. The chambers do not clog and allow the liquid waste to be passed through and soaked into the ground. In fact, it is a suitable substitute where the water tables are very high and there are low drainage facilities.
Pros: More convenient to put in than conventional units; efficient in areas where soil conditions are not favorable.
Cons: Can be more than average system; regular maintenance is still a must
- Drip Distribution Septic System
Average Cost: 8000 and 18000
Description: This system employs small-diameter piping with nozzles throughout the network, which allows for the regulation of wastewater distribution into the soil and over a larger area. It is preferred in places with shallow soils or cumbersome terrain.
Pros: Ideal for adverse site conditions as well as rough soil as they evenly distribute effluent.
Cons: Are more time-consuming and require more energy while constructing the system and installing now; are relatively more expensive.
- Aerobic Treatment Unit (ATU)
Average Cost: $10,000–$20,000
Description: Aerobic treatment units use oxygen to decomposes organic matter more efficiently than anaerobic systems. This kind of systems is common in areas of soil or environmental regulations which do not allow normal septic systems.
Pros: Works in places with little soil or where normal system cannot work; more effective than a regular sewer in treating wastewater.
Cons: More costly to install and maintain; certain effluent treatment units need pumping and electricity to run.
- Recirculating Sand Filter Septic System
Average Cost: $7,000–$18,000
Description: In this system, wastewater is passed through sand in several layers before it is discharged onto the drainfield. It is applicable in places where soils are poor or water tables are shallow.
Pros: Very good treatment and filtration system.
Cons: More cost rates in the initial stages and maintenance.
- Evapotranspiration Septic Systems
Average Cost: $10,000–$15,000
Description: In this system, the waste water is enclosed in a waste basin where the waste water evaporates or the plants absorb. This works best in dry and bushy or deserts with very poor soil percolation.
Pros: There are no drains, therefore no drainfield is needed, very good in dry places.
Pros: Locations where constructed wetlands can be useful, are very few.
- Septic System-Constructed Wetland
Rarely, except gravelly land, average cost: $5000-12000
Description: Constructed wetlands, also known as treatment wetlands or wastewater gardens, are man-made ecosystems that simulate the natural processes of wetlands as an approach to wastewater treatment. The effluent goes through plants and soils that adequately assimilate the effluent.
Pros: Green concept and good waste water treatment.
Cons: The vegetation and their supporting system will need to be updated periodically to avoid failing systems.
- Cluster/ Community System
Rarely cost:$500 USD too, Almost gives for free (depends on the number of homes and system design)
Description: A cluster is a centralized system that is utilized by a community of homes. Each cluster system includes a common septic tank and a drainfield where effluent is discharged which extends over a specified area. Such systems are preferred in rural expansions which do not allow for individual systems.
Pros: Affordable solutions for big sized communities; responsibilities of maintenance are divided.
Cons: Priceing is dependent a lot on the population of the community and system design as many variables come into play.
Cost Estimate Summary:
Average Cost of Various Types of Septic System
Anaerobic – $3,000 – $8,000
Chamber – $5,000 – $12,000
Drip Distribution – $8,000 – $18,000
Aerobic Treatment – $10,000 - $20,000
Recirculating Sand - $7,000-$18,000
Evapotranspiration ………….$10,000 - $15,000
Constructed Wetland – $5,000 – $12,000

Final Thoughts
Several variables will factor towards the selection of the septic system suited for your home. These include the soil types, water levels, government acts, and even the finances. Cost-monitoring biogas systems are usually the simplest to install. However, around difficult environments, alternative solutions such as aerobic treatment units, or more advanced drip distribution systems may be required. Any system selected needs to be periodically serviced and serviced for efficiency ofteh whole system administered in space.
