Sewage Treatment Plants in Dorset
Wastewater solutions for commercial sites, rural properties and developments without a suitable mains sewer connection
Where connection to the public sewer is unavailable or impractical, a sewage treatment plant can provide an alternative method of treating wastewater.
Dorset Drainage Services can advise on and install sewage treatment systems for commercial properties, rural developments and domestic premises.
Commercial & Development Applications
For larger projects, plant selection must consider expected loading, site conditions, discharge arrangements and future maintenance requirements.
Treatment plants may be required for:
- Commercial premises
- Rural businesses
- Industrial and agricultural sites
- Residential developments
- Offices and workplaces
- Hospitality sites
- Schools and community facilities
- Individual rural homes
- Groups of properties
How a Sewage Treatment Plant Works
Wastewater enters the treatment system where biological processes break down contaminants. Treatment plants mechanically aerate the effluent, encouraging aerobic bacteria to treat wastewater before it leaves the system.
The exact plant and discharge arrangement depends upon the project.
Treatment Plant or Septic Tank?
01
Septic tank
Provides settlement and initial treatment before effluent passes onward to a suitable drainage field or other compliant discharge arrangement.
02
Sewage treatment plant
Adds active biological treatment and aeration, producing a more highly treated effluent before discharge.
For new projects, we can discuss the site and intended use before recommending the most appropriate route.
Site Assessment & Installation
A treatment plant installation may involve:
- 01Reviewing property or site requirements
- 02Assessing likely capacity
- 03Establishing ground and access conditions
- 04Excavation
- 05Installing the plant
- 06Connecting inlet and outlet pipework
- 07Installing associated drainage
- 08Commissioning and reinstatement
Where planning, environmental or discharge requirements apply, these should be established for the individual project before installation.
Replacing an Existing System
Older private wastewater systems may no longer meet the needs of a site or may suffer from repeated soakaway or operational problems. We can assess the existing arrangement and discuss options for replacement or improvement.
Commercial & Rural Site Considerations
For businesses and multi-property sites, wastewater treatment needs to be considered as part of wider site infrastructure. Access for future servicing, capacity, drainage routes and the relationship with other buildings should be factored into the project from the outset.
Why Use Dorset Drainage Services?
A treatment plant project may require much more than simply supplying the tank. Our wider drainage capability allows related excavation, underground drainage, connections and reinstatement to be coordinated as part of the same project.
Domestic Systems
We also install private wastewater systems for homes that cannot connect conveniently to mains drainage. Plant capacity should be selected according to the actual property and usage rather than simply choosing a system based on price.
Coverage
Treatment plant installation across Dorset and the South Coast
We undertake private wastewater projects throughout Dorset and surrounding areas, with larger commercial or development projects considered further afield by arrangement.
FAQ
Frequently Asked Questions About Sewage Treatment Plants
When might I need a sewage treatment plant?
Typically where a suitable mains sewer connection is unavailable and private wastewater treatment is required.
How does it differ from a septic tank?
Treatment plants mechanically aerate wastewater and provide an enhanced biological treatment process.
Are treatment plants noisy?
Correctly operating modern systems are generally quiet, although individual plant characteristics vary.
Do they need maintenance?
Yes. Mechanical treatment systems require ongoing maintenance and periodic desludging in accordance with the manufacturer's requirements.
Can you advise what size plant I need?
Yes. Site usage and expected loading need to be considered when selecting the system.
Can you replace an existing septic tank?
Where replacement or upgrading is required, we can assess the existing arrangement and discuss suitable options.
