Five Key Factors for Septic Tank Installation
Septic tanks are usually formed as containers underground that hold sewage water in order for it to decompose and drain away. Here at FlowRite Drainage, we specialise in septic tank repair and installation in West Sussex, and are pleased to cover some considerations needed when installing septic tanks. Read on to find out more.
Septic Tank System Design
When considering the design of your septic tank system, it is important to note that it consists of two main elements: the tank and the percolation area/discharge area. The design takes into account the amount of waste that is being regularly dealt with, for example, considering the number of people in a household. Any treated effluent that leave the septic tank should flow into the percolation area. This area typically consists of a soakaway, which is a gravel-based infiltration area, where the waste is dispersed and soaks into the soil. The design will also need to consider the soil conditions, depending on whether the ground is very permeable with a high infiltration rate or not. It is not possible to simply connect the septic tank to a drain or stream, therefore a sewage treatment plant would be required.
The Right Septic Tank or Sewage Treatment Plant
As outlined, if you include a soakaway or percolation area then you will be able to install a septic tank, but if you don’t then you will likely need a sewage treatment plant. The difference is that a septic tank is usually made from concrete or reinforced plastic, with existing tanks possibly from the former, whilst most new models made from the latter. Modern septic tanks also use a single piece rather than a separate lid, which means there is no risk of leaking. A sewage treatment plant, or wastewater treatment plant works by a system that collects sewage, which is treated by various means and can then be discharged to a watercourse or into the ground.
Septic Tank Installation
Whilst it is possible to install a simple septic tank yourself, you should also consider the complexities of this, not only physically, but also legally, needing to make sure that all drainage works completed meet the required building regulations. At FlowRite Drainage, we offer efficient septic tank installations and repairs at an affordable price. If you have an existing problem, we provide bespoke solutions, and can also offer assistance with insurance claims if it as a result of accidental damage.
Septic Tank Ventilation
Good ventilation is necessary to lessen the environmental impact, as poor ventilation can create odour issues onsite. The ends of the percolation trenches should be vented, and there should also be a vent on the treatment plant, or if at a domestic resistance, there should be a soil vent stack at the house.
Septic Tank Maintenance and Operation Access
Lastly, you should also consider the maintenance and operation access of your septic tank. Here at FlowRite Drainage, you can be assured in the knowledge that we will always be at hand to help if you need any future assistance, but you should also make sure lids are not covered in soil, and that access is open for emptying and inspections. It is also worth remembering that the tank should be within 30 metres from a driveway for emptying, or else these costs could increase.
