Sewage Treatment Plants

Sewage treatment plants are specifically engineered to treat wastewater, where mains drainage is unavailable. The treatment plants that we supply at Cotterill Civils are easily adjusted to meet the requirements of populations.

What are sewage treatment plants?

Sewage treatment plants clean wastewater, making sure the treated water, called liquid effluent, flows safely into the environment.

Here at Cotterill Civils, we supply a complete range of sewage treatment plants (or domestic treatment plants, as they can also be referred to), offering something suitable for everyone. No matter which of our domestic treatment plants you choose, they each offer exceptional value for money and are guaranteed to sustain a high-quality standard for longer.

We supply domestic treatment plants with hundreds of options, taking into consideration your specific drainage needs. Can you afford not to check out our extensive range of products below?

Our sewage treatment plant options

The sewage treatment plants that we have available are supplied in various sizes, ranging from smaller chambers like the domestic treatment plants accommodating up to six people to high-volume industrial treatment plants suitable for more than 50 people. If you cannot find exactly what you’re looking for, this isn’t a problem for the team here at Cotterill Civils, because we have bespoke options available!

As with any of the products that we are proud to supply, we stock sewage treatment plants from an assortment of established brands, including Kingspan, Klargester, Marsh, and Clearwater, so you needn’t worry about finding something suitable.

How do they work?

Investing in a domestic sewage treatment plant will allow you to remove contaminants from sewage and ensure that effluent water is removed effectively.

In scientific terms, oxygen is consistently introduced into wastewater or sewage using a mechanical aeration device, such as an air blower or compressor. Aerobic microorganisms, including natural aerobic soil bacteria, then consume the organic matter in the wastewater, breaking it down into carbon dioxide and biomass that can be subsequently removed.

Domestic sewage treatment plants offer a modern alternative to other methods of sewage treatment, providing you with a convenient storage solution for water when your main supply is not available or reachable.

At Cotterill Civils, we supply the sewage treatment plant as a cost-efficient solution for managing your drainage system, ensuring that waste material is deposited safely and correctly. Generally, the treatment plants provide low lifetime costs, allowing you to get more out of your products before they need to be replaced.

Who needs a sewage treatment plant?

A sewage treatment plant is a versatile investment to make; it suits the requirements of customers who are purchasing for their home or their business.

From our wide range of sewage treatment plants, we supply domestic treatment plants designed to meet the needs of homes located away from drainage mains. However, we also cater to commercial customers with specialised commercial sewage treatment plants and septic tank needs.

Frequently Asked Questions

How do sewage treatment plants work?

The way a sewage treatment plant works is relatively straightforward. Wastewater and sewage enter a large settlement tank, where solids sink to the bottom and form ‘sludge' and liquids flow through to a chamber. A pump airs the waste and promotes friendly bacteria to condense the organic matter, breaking it down and purifying the water. When the water leaves the final chamber, it's more than 95% clean – meaning it can be safely dispersed into local ditches or a soakaway sewage system, providing consent has been given from the Environment Agency.

Which size sewage treatment plant is best?

Sewage treatment plants come in a variety of sizes – ranging from 5,950 litres to 184,000 litres. The size you need often depends on the size of your property, how many bedrooms you have, and the number of people that will use the treated water (both now and in the future). For example, a single dwelling with up to 12 people will benefit from a smaller sewage treatment plant than a group of houses with 13 occupants or more between them. If you're unsure, our team at Cotterill Civils is always on hand to help and will happily guide and advise you in making the right choice. Simply give us a call on 0121 351 3230.

Are sewage treatment plants worth the investment?

Though we might be biased, we believe that a domestic or commercial sewage treatment plant is a worthwhile investment for anyone not connected to the main drainage network. Whilst they work similarly to septic tanks, they use a mechanical system to pump oxygen to the microorganisms. This allows them to treat effluent more effectively, so it can be discharged directly into flowing water. Sewage treatment plants are a moderate investment, but they generally work out cheaper to run in the long term. Compared to other sewage systems, they don't need to be emptied as frequently, helping to save money on maintenance. To find out more about sewage treatment plants and how further treatment can benefit you, get in touch with our team at Cotterill Civils.

How often should a sewage treatment plant be emptied?

In most cases, a sewage treatment plant will only need emptying once a year to ensure it's functioning correctly. This is great for keeping your maintenance costs to an absolute minimum. However, if your system is larger and used frequently, it may need desludging more often to ensure you don't run into any technical issues. If you're unsure how much maintenance your own sewage treatment plant needs, don't hesitate to talk to the team. We're always on hand and will gladly advise you. We can even provide tips to help prolong the lifespan of sewage treatment plants.
