Treatment Plant Installation Case Study

Subject Property and Drainage Network 

The subject property had reportedly had problems with the constant high levels of  effluent building up in the current septic tank. So much so that the tank has required  constant emptying and at considerable cost. 

The Septic tank was populated via two manholes (MH1 & MH2). Both are situated  on the side of the property and had positive natural flow. 

Ecodrain Solutions proposed the installation of a Sewage Treatment Plant that will be able  to treat the waste and provide acceptable effluent that will run to a new drainage field.

Sewage Treatment Plant 

Acting as an independent waste water treatment system, a domestic sewage treatment  plant would be installed into the rear of the property. It is a self-contained plant that is  designed to receive all of the waste water from the dwelling and promote the growth of  Aerobic Micro-organisms which degrade the receiving waste water producing a treated  effluent suitable for discharge to a natural water courses or drainage fields. 

The specific plant we proposed is an industry leader that we were confident would treat the waste efficiently and at very low operational cost. 

Some facts about the proposed Sewage Treatment Plant: 

∙ Extremely clean effluent – up to 98.9% pollutant reduction.  

∙ Fully adjustable to suit the number of people using it. 

∙ Low electricity consumption for the air pump – from only £25/year. 

∙ Much lower maintenance costs than Non-Electric Treatment systems. 

∙ Odourless – complete aerobic digestion throughout the sewage treatment plant. ∙ One piece tank construction – not sectional – no leaking seals. 

∙ Recycles its own waste products resulting in less sludge to remove. 

∙ No Primary Settlement Tank – No Primary Tank Odour. 

∙ 10 year tank warranty- no metalwork to corrode inside or outside the tank. 

∙ Accepted by the Environment Agency for discharge without the need for a permit

The Installation Process

The installation of the plant was a methodical procedure that required working from the  side to the rear of the house (current manholes), the side patio and then into the  garden.

The most important thing about the operation of any drainage network is the positive  natural flow of the system. Plainly put, water runs down. The subject property’s current  network had the building’s foul waste make its way to and through Manhole 1 & 2, then  ultimately through a drainage pipe to the septic tank. Manhole 1 is 535mm deep and  Manhole 2 is 830mm deep. These depths provide enough slope for waste to travel.  However, the sewage treatment plant Ecodrain Solutions proposed to install had invert inlet depth options of 200mm, 500mm and 950mm. Due to the topography of the  subject property we recommended the 500mm inlet depth so the plant outlet is high  enough for the new drainage field to work effectively. This recommendation meant that we needed to change the depths of the current Manholes whilst presenting  positive flow leading to the sewage treatment plant. 

Additional to the Installation of the foul water network, we requested that the homeowner liaise  with the owner of the adjacent Horse Field and install temporary access to Ecodrain  Solutions for delivery and use of machinery (Digger & Dumper Truck), materials and the  delivery of the sewage treatment plant itself. 

Installation Process: 

∙ Pulled up and store patio slabs 

∙ Excavated and removed old manholes and installed new manholes to correct height. ∙ Installed a mini manhole prior to the proposed plant (for future access and  inspection).

∙ Excavated (approx. 2m deep & wide) and prepared base for plant installation. ∙ Excavated trench for drainage pipes from plant to mini chamber. 

∙ Excavated and installed a mini chamber (for future access and inspection) 

∙ Excavated a trench for drainage pipes from the mini chamber to drainage field. 

∙ Excavated and installed a drainage field. 

∙ Installed an electrical line from the subjects property to the plant (for air pump operation).

∙ Secured and attached the plant by cuffing using cement and stone. 

∙ Connected and tested the system. 

∙ Backfilled all excavations and left the site level.

We are Proud to Announce our Partnership with Onetreeplanted.org

We care about the planet and creating a business that gives back to nature. That’s why we’re thrilled to share that we’re partnering with One TreePlanted to donate a share of each jobs profits to help plant trees across the UK.

Trees clean our air and water, create habitats for biodiversity, contribute to our health and wellbeing, and create jobs for social impact. We’re honored to have reforestation through One Tree Planted as an integral part of our business model.

The objectives of this new partnership include:
 
  • Supporting UK focused reforestation efforts (can be global too)
  • Empowering consumers with sustainable actions
  • Raising awareness about the importance of ecosystem restoration

Planting trees is one of the best ways to combat the damaging effects of climate change. Trees help clean the air we breathe, filter the water we drink, and provide habitat to over 80 percent of the world’s terrestrial biodiversity.

Trees also provide tremendous social impacts by providing jobs to over 1.6 billion people, empowering women in underdeveloped nations, and supporting communities devastated by environmental damage.

The partnership is designed to be simple for customers to get involved in global reforestation. For every job we do for our customers, the company will donate a % of the profits to One Tree Planted to plant trees. The trees are planted by local partner organizations and community volunteers in areas where there has been deforestation. 

Customers will get an email to confirm their tree donations after the job is complete.

“We’re excited for the opportunity to work with onetreeplanted on such an impactful project, and are committed to planting trees for every job done. It’s a prime example of how companies can make positive change for our planet."
