Warning High Rainfalls

Septic tank desludging or emptying your sewage treatment plant can be risky in heavy rain. Rain entering around the system can cause massive pressure build-up, resulting in it popping right out of the ground! Here we explain the effects of high rainfall, how to fix a flooded tank, and solve your issues.

Allerton Ground Water Tube (AGWT)

If you are concerned about the water levels in the area of your soakaway, you can always dig a hole to see what the groundwater level is. We have a tool to make reading the water level easier! This blog post tells you all about ground water in soakaways, the AGWT, and how to try it out for yourself.

How to do a percolation Test

The purpose of a percolation test is to see how long a field drain (soakaway) you need for your Sewage Treatment Plant. One might also call it a soakaway size calculator. Here we give you the tools and knowledge to do it yourself at home.

Allerton’s good work filters through

Allerton were recently asked to assess a small sewage treatment system from the 1940’s, at a home in Lincolnshire. It was clear from the initial inspection that the system wasn’t operating well. As with all sewage treatment systems, periodic maintenance is required. Read more to find out how we got it running like new again!

GRP Septic Tank

GRP Septic tanks replaced brick-built septic tanks about 40 years ago. GRP stands for Glass Reinforced Plastic, also known as fibreglass. We use it in nearly all our products, including septic tanks and the Allerton ConSept. Here we discuss GRP, its applications, and how we use it to provide our 5-star septic tank services.

ConSept Installation in a Listed Building

The ConSept is a piece of equipment we designed to fit inside a septic tank (brick or GRP) so as to convert it to a functional Sewage Treatment Plant. After applying for a permit with the environmental agency, they’re generally accepted. The site in this case was a grade 2 listed building in Takeley, Essex.

Overflowing ConSept

The customer’s ConSept had overflowed in the distribution chamber; the distribution chamber (downstream of the ConSept, inside the Klargester Septic Tank) was overflowing onto the lawn. Come with us as our engineers provide their septic tank repair services.

Mr Hodgson’s Flooded Cellar

In the year 2010, Mr Hodgson approached Allerton with a problem: When it was raining, water entered the cellar from the floor and walls, causing a flood 6 inches deep. The cause was a high water table in the Sleaford area. Read on to find out Allerton’s genius solution!

Wouldn’t Even Know It Was There

The Allerton ConSept is a piece of equipment we designed to fit within your existing septic tank, to turn it into a functioning sewage treatment plant. Come along with us on this installation of an Allerton ConSept septic tank conversion, in Carlton Scroop, Lincolnshire.

A Dirty Job

A cesspool is an underground tank used to store raw sewage until it is emptied by a suction tanker. About 20 years ago, before Confined Spaces laws were brought in, Jon Allerton had the task of converting a large cesspool into a pump chamber. Follow along this sewage adventure in our blog post.

ConSept Pipe Overhanging Ditch

Our engineers hand-dug and reinstated the ground for an outlet pipe on a ConSept recently. The pipe is overhanging the ditch directly above water so that it does not corrode the bank around it. Follow along with our engineers in this blog post!

Control Panel Relocation

We had to relocate a DRS (Dual Raw Sewage) control panel in Ruskington. To do this we had to identify where it was discharging to! So we put bright green vegetable dye in the system to see the sewage discharging into a ditch. Here are the results!

How do you convert raw sewage into clean water?

Raw sewage, starting at around 300 BOD (estimated by British Water) can become as little as 20 BOD once treated by a Sewage Treatment Plant, which can be discharged into ground! Read on to learn all about the process.

Allerton Engineers at Work

After removing discs from a Klargester Sewage Unit at Scunthorpe Steelworks, two Allerton Engineers fitted a new rotor and bearings. The discs revolve, dipping into the dirty water and turning in the fresh air, giving the aerobic bacteria what they need: food, water and air. Follow along as our sewage engineers go to work!
