Professional Sewage Treatment Plant Installation in Wrexham
If your property in Wrexham is beyond mains sewer reach, whether a rural home, new build, business, or renovation site, a reliable and compliant sewage treatment plant (STP) is essential. At C&L 24Hr Emergency Drainage, we provide full installation services for STPs across Wrexham and surrounding communities, combining local expertise with robust technical standards.
We are a family-run business with more than 25 years’ experience in drainage and wastewater systems. Our work spans Wrexham and beyond, and we are dedicated to delivering installations that are efficient, durable, compliant, and minimally disruptive.
Why a Sewage Treatment Plant is the Better Option
Unlike septic tanks that simply separate solids and liquids, STPs employ aerobic biological treatment to reduce organic pollutants. The result is much cleaner effluent that can be safely discharged to a watercourse or soakaway when permitted. Modern STP systems align with EN 12566-3 standards, ensuring structural integrity, durability, and conformity to regulatory obligations.
With increasing regulatory scrutiny in Wales, installing a compliant STP now helps avoid future upgrade costs or enforcement.
Our Installation Service from Site to Commissioning
We deliver a comprehensive, end-to-end service:
- Free Initial Site Survey: We visit your Wrexham property to assess soil, access, discharge routes, and usage demands. This ensures we recommend an appropriate system size.
- Tailored System Design: Based on your needs, we specify an STP from trusted manufacturers, with capacity suited for domestic or commercial use. All units are EN-certified and fully compliant.
- Building Control Taken Care Of: We will ensure your plant is installed to building regulation standards. The building control officer will make one or two site visits to ensure we are installing your plant correctly. Once we have completed the installation, the plant will be signed off.
- Excavation and Installation: Our skilled team handles excavating, base preparation, pipework, electrical setup, blower integration, and system placement.
- Commissioning and Testing After installation, we run full tests, ensure correct operation of pumps, alarms and aeration, and confirm the system is delivering to specification.
- Reinstatement and Handover We restore disturbed ground, paths, or driveways, and provide you with full operating instructions, maintenance advice, and documentation.
