Sewage Treatment Plant

Sewage treatment plants are highly effective at treating waste and have very low impact. They use bacteria to remove up to 97.8% of the pollutants, before discharging the effluent into a (much smaller) drainage field. They are therefore suited to even the most sensitive sites such as close to freshwater lakes, rivers and streams - or where the water table is very high. Maintenance and running costs are relatively low for sewage treatment plants.

 Sewage treatment systems work in a similar way to septic tanks, with sewage first flowing into the first chamber of the treatment plant. In this chamber, grease, oil and scum will be separated onto the top of the tank, with the solids settling on the bottom. The liquids in this chamber are moved onto a second section, where air is pumped into it to grow the amount of aerobic bacteria in this sewage, which will break down the contaminants in the water. Once this water has been cleaned, this liquid moves onto a final settlement tank, where the few remaining solids are allowed to sink to the bottom of the tank before its contents are discharged into a soakaway or watercourse.

 

Wastewater Treatment

There are 3 main stages for wastewater treatment.

  1. Sewage flows from the property into the first chamber of the sewage treatment plant. Here, the water sits until grease, oil and scum have floated to the top and solids have settled on the bottom of the tank.
  2. Once the process of separation has taken place, the liquid travels into a second chamber. This chamber is fitted with an air pump or blower that circulates air around the chamber to encourage the growth of aerobic bacteria. This bacteria helps to break down the contaminants in the water.
  3. The final stage of a sewage treatment plant is one last settlement tank. This final tank allows the very last solids that may remain to sink to the bottom of the tank before the effluent is discharged into a soakaway or watercourse. Once the treatment process has been completed, it can be discharged into a soakaway pit or water course.

FAQs

What are the 3 types of sewage treatment?

  • Primary wastewater treatment

The primary treatment of wastewater removes material that will either float to the top or settle to the bottom. The wastewater is temporarily held in a settling tank where the heavier solids sink to the bottom and lighter bits float to the surface. Once settled, these solids are held back while the rest of the liquid is moved through to the secondary phase of wastewater treatment.

  • Secondary wastewater treatment

A deeper and more rigorous secondary phase of wastewater treatment uses aerobic biological processes to substantially degrade the biological content of the waste, reducing common biodegradable contaminants down to safe levels. There are three ways to do this: biofiltration that uses filters to ensure that any additional sediment is removed from the wastewater, aeration which increases oxygen saturation by introducing air to wastewater and oxidation ponds that allow wastewater to pass through natural bodies of water for a set period before being retained for two to three weeks.

  • Tertiary wastewater treatment

Tertiary wastewater treatment aims to improve water quality to meet domestic and industrial standards. It involves removing pathogens to ensure water is safe for drinking

How does domestic sewage treatment work?

A domestic sewage treatment plant works by breaking down solid waste to produce a cleaner, more environmentally friendly effluent. Wastewater and sewage are supplied to the primary tank, where the solids separate and from the liquid and then flows into the biozone chamber. Here, a pump airs the waste and friendly bacteria is used to condense the organic matter, breaking it down. When the waste leaves the final waste chamber, it is 95% clean and ready for dispersal into soakaway systems, subject to consent from the relevant environmental agency.

What is the difference between a septic tank and a sewage treatment plant?

Although the two are often mistaken as the same thing, there are some distinct differences between the two. A sewage treatment plant creates a clean, environmentally friendly effluent which can be discharged directly to a watercourse. They often require electricity to operate and need regular servicing and emptying. A septic tank only needs emptying once a year, doesn’t use any electricity and doesn’t require servicing. However, they produce a very polluting waste product, which must be dispersed to a soakaway and the septic pollutants go through further handling by the natural aerobic soil bacteria.

How I do install a sewage treatment plant?

It is strongly recommended that a suitably trained and qualified professional installs your sewage treatment plant. You could be faced with hefty repair costs, fines and even legal issues (that will be far greater than the cost of hiring a professional installer) if any part of your private sewage system is installed incorrectly. If you are confident you have the skills to do this yourself you should have step by step instructions on how to do it from the manufacturer of your chosen tank, plus all the health and safety measures that should be taken. The following will give you a brief guide on what will be involved in the install, but always ensure you adhere to the manufacturer’s guidance as some steps may vary.

  • Inspect tank for damage

Although our tanks will have been fully tested and checked before being dispatched to you, make sure to thoroughly inspect the tank for any damage caused during transportation as, once the tank is installed, we may not be able to accept your return.

  • Placing the tank

Ensure your hole is large enough for the both the tank and the recommended backfill. Prepare a base for the tank and carefully lower the tank into the hole, using the recommended lifting system, checking that the inlet and outlet orientation is correct. Ensure your tank is level and use the correct backfill, which might be concrete, gravel or sand, but check the manufacturer’s manual to see what they advise and follow their steps for adding the backfill.

  • Installing the inlet and outlet

Installing the inlet and the outlet should be straightforward, but it is always worth contacting a qualified plumber if you are unsure. Follow the manufacturer’s installation guide to connect the pipework. For easier maintenance access, some manufacturers advise the install of an inspection chamber before and after the treatment to make life easier should any problems arise in the future.

  • Wire up the electrics

All electrical work should be conducted by a qualified electrician. The installation manual will detail what is required.

This is a very simplistic guide of what is required to install your sewage treatment plant. In addition to these steps, you may also need to install a soakaway to complete your system.

How do I need to prepare to install my sewage treatment plant?

It is highly recommended that you fully understand and adhere to all the regulations that will affect your installation and running of a sewage treatment plant. If you are the property owner where the tank is being installed, this is your sole responsibility and you could be liable to heavy fines or repair costs if things are done incorrectly.

Invert Depth, what is this?

It is the level of the soil pipe entering the septic tank or treatment system.

Gravity or IPS, what is the difference and when would I need them?

If the flow from your system can not release without help, i.e. required to be uplifted you would need a pump to help with this.
