Who We Are

Comprehensive Drainage Groundworks & Installation Services

Our team provides a full spectrum of drainage installation services tailored for properties in Treharris and the surrounding areas. We manage every step, from initial site assessment and design to excavation and final connection. Our expertise covers:

  • Septic Tank Installation & Wastewater Treatment Plants: For properties not connected to the mains sewer, we expertly install and connect modern septic tanks and advanced wastewater treatment plants, ensuring full compliance with the latest 'General Binding Rules'.
  • New Foul & Surface Water Drainage Pipes: We lay all necessary pipework for both foul sewage and surface water drainage, guaranteeing correct gradients and connections to ensure optimal flow and prevent future issues.
  • Soakaway Design & Installation: Essential for managing surface water runoff, our bespoke soakaway solutions are designed following percolation tests to effectively dissipate water back into the ground, reducing flood risk.
  • Aco Drain & Channel Drain Installation: We install effective surface water channels around driveways, patios, and commercial premises to prevent standing water and manage runoff efficiently.
  • Sewer Connections: Connecting your property's drainage to the public sewer network requires specialist knowledge and liaison with Dŵr Cymru Welsh Water. We handle the entire process, including any necessary 'build-over' agreements.
