The Benefits of Installing a Sewage Treatment Plant
There are several key benefits of choosing a sewage treatment plant over a septic tank or cesspit. Sewage treatment plants need to be professionally emptied less often than a septic tank and far less often than a cesspit. Wastewater from a sewage treatment plant can also be directed straight into a watercourse like a ditch or a stream.
This is the only legal option if you are looking to discharge effluent into a watercourse, as septic tanks can legally only be discharged into the soakaway drainage field, and cesspits do not discharge waste.
Sewage treatment systems save money on drainage, are better for the environment by offering wastewater treatment, and allow you to keep ahead of any future legal changes governing septic tanks and cesspits.
The Cost of Installing a Domestic Sewage Treatment Plant
While installation costs can vary depending on the size of the tank needed, and the complexity of the job, you will be looking at a cost of roughly £7000 to £9000 for both the tank and installation. While this is a few thousand pounds more than a septic tank, you will not need to empty the tank as often and are protected from future law changes around septic tanks and cesspits. Cesspits require very regular drainage and are a great expense for households.
If you are currently using a cesspit for household sewage, you should consider the savings that will come from moving to a more cost-effective system that doesn’t require regular drainage.
