Wastewater is a reusable resource. It can be treated and recycled back into groundwater. This article takes a look at the wastewater system and answers the question, How do I choose an appropriate onsite wastewater system?

Cities and towns use a central wastewater system. On the other hand, in smaller communities or homes separated away from the city, the onsite wastewater system must be used. First, take a look at your land. Is your land hilly or flat as in the plains? Second, is your property located near rivers or lakes? Third, what kind of soil is your property on?

Onsite wastewater systems are made up of a septic tank, a treatment unit, a filter, and a dispersal unit. Some systems may combine the treatment unit with the filter unit. Picture a pit latrine or outhouse. The hole in the pit is a septic tank. If there is a ventilation pipe that is put into the pit, it allows for air to flow out of the pit. The bad odor is transported out of the pit through heat convection during summer.

In winter, the excreta get frozen. In this case, inside the pit, the wastewater treatment filters through the sand into the surrounding soil. The sand acts as a filter and a natural dispersal unit. The treatment takes place naturally in the pit with bacteria but it is not efficient. This system can still be used until the pit is full. The pit is covered up and a new one dug and the cycle repeats.

The only thing bad about this is if there is a river or lake nearby, the effluents from the pit latrine will contaminate the river or existing well water. These septic tank systems would probably be used in cabins or in a remote location.

The other more common type of onsite wastewater system is the one which uses the flush latrine located within the home. The wastewater flows into a septic tank, out into an aerobic treatment unit (ATU) and a gravity effluent distribution device. The septic tank is a watertight covered container. The sewage comes from the sewage pipe running from the flush latrine. The septic tank is normally placed underground.

As the wastewater goes into the tank, solids and liquids are separated through gravity. Solids sink and become sludge while fat and grease float. In between is a clearer layer of effluence which flows out of the septic tank into the ATU. In the ATU, air is mixed into the wastewater and aerobic bacteria break down and remove the solids. The wastewater flows into the effluent distribution device through gravity. Here, sand or peat can be used as filters. As the wastewater goes through the sand, particles are trapped and clearer water is obtained. The wastewater is then dispersed to the surrounding soil.

So, it really depends on your locality and what type of home you are staying in. The above should help answer the question nagging you, How do I choose an appropriate onsite wastewater system?

Handling wastewater in a safe way is vitally important for all of us who need water to survive. Wastewater treatment therefore is a viable and important procedure for us to obtain viable and usable water. There are a variety of different methods and disposal of the waste water that is created on a daily basis.

The definition for wastewater treatment would be using known technology to enhance or improve the quality of our water. What is normally done with most waste water is to gather it up and make sure that it is run into a common area for the beginning of its treatment. This is usually your local area wastewater treatment plant.

Water that needs to be treated is generally put through a variety of different processes for complete treatment. When it is large flows of water, then the water will be in a continual flowing state and be treated in than manner. There are times though that certain wastewater treatment is handled in batches.

Even though wastewater is handled with the continuous flow procedure there are times that a batch process is used. This is generally when the water is known to have sludge in it and they need to treat the water and the sludge in a smaller contained area. This is when they will add chemicals to this particular water to try and break down the sludge.

There are three different categories that the procedures can be put into. The first one being physical, the second is chemical and the last one is biological. Some of the wastewater will sometimes need all three categories to process the water properly.

Also certain types of wastewater need specific categories for treatment and not all three. Below are the different categories and what is used in them for the treatment process.

Physical category would use these items for processing; sedimentation, filtration, aeration, floatation, skimming, etc.

Chemical category would tend to use the following; chlorination, neutralization, coagulation, etc.

Biological category would deal with active sludge treatment, trickling filtration, oxidation ponds, aerobic digestion, septic tanks and more.

The physical category means that they use physical objects to help with treatment like screens and filters for example.

The chemical category is when they chemicals to cause chemical reactions in order to change the quality of the water.

The biological category means that they use organisms, especially bacteria that will help decompose items that need to be broken down into organic material.

When using the chemical treatment they make use of units called feed units, mixers and other similar devices.

Treatments have different types of levels, preliminary, primary, secondary and tertiary. Tertiary is the only one that can not be done alone, this generally is added to the secondary treatment.

Preliminary is when they need to remove items that might damage the equipment that is used for treatment. This is done with shredders, screens, grinders, etc.

Primary is when the water is gathered into settling tanks and give the water time for the sediment to drop to the bottom of the tanks.

Secondary treatment is the use of aerobic organisms that will help break down anything that can not be broken down on its own. Some of the items they use in this procedure are filters, sand filters, final settling tanks and stabilization ponds.

Installing septic tanks is an effective and highly recommended method for reducing the ecological impact on the environment. Nowadays, wastewater treatment has innovative technologies such as dispersal pipes and grease trap interceptors.
