Specialist Sewage Treatment Plant Installation in Oswestry
If your property in Oswestry, whether residential, agricultural, or commercial, is not connected to the main sewer system, a modern sewage treatment plant (STP) is the smart, sustainable solution. At C&L 24Hr Emergency Drainage, we offer expert STP installation tailored specifically for the Oswestry area. As a trusted, family-run company with over 25 years of hands-on experience, we ensure reliable and compliant installations.
Why Choose a Sewage Treatment Plant?
Unlike traditional septic systems, STPs use aerobic biological processes to treat wastewater, even from kitchens, bathrooms, and appliances, resulting in clean effluent that can be safely discharged into watercourses or soakaways. These systems align with EN 12566-3 standards, certifying their durability, watertight integrity, and environmental performance. Investing in an STP supports long-term property value, helps you remain compliant with environmental regulations, and protects the picturesque environment of Oswestry.
Our Comprehensive Installation Process
We manage every phase of the installation smoothly and professionally:
- Free On-Site Assessment: We evaluate soil type, percolation, discharge possibilities, and system sizing to recommend the best solution.
- System Selection and Design: Whether you need a compact system for a cottage or a robust unit for a larger property, we supply EN-approved systems from reputable brands like Clenviro, Tricel Novo, and Kingspan Klargester, tailored to your needs.
- Building Control Taken Care Of: We’ll 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. When we have completed the installation, the plant will be signed off.
- Installation and Commissioning: From excavation and base preparation to electrical connection, blower setup, system testing, and commissioning, our technicians handle every detail with care.
- Site Reinstatement and Handover: Once complete, we restore all disturbed ground and thoroughly explain system operation, maintenance, and recommended servicing intervals.
