Septic Tank Repairs
Septic systems that leak, back up, or emit unpleasant odours are not only inconvenient but can pose serious health risks and lead to expensive repairs. Fastfix Drainage And Plumbing carries out targeted septic tank repairs using proven diagnostic methods: CCTV drainage surveys, dye testing, water-tightness checks, and structural inspections. We repair cracked concrete tanks, replace damaged baffles and lids, rectify pipework faults, and reseal joints to stop leaks. Our repair services help maintain your system’s lifespan and are carried out with minimal disruption, using materials that meet industry and British Standards.
Septic Tank And Sewage Treatment Plant (STP) Installation
If your property isn’t connected to mains drainage, installing a reliable septic tank or Sewage Treatment Plant is a significant investment essential for effective wastewater management. We design and install bespoke systems sized according to your property’s occupancy and tank size, complying with Building Regulations, Environment Agency guidance, and new requirements. Our professional installation services include thorough site assessments considering ground conditions, tree roots, and access constraints. We handle all groundworks, tank siting, pipework, electrical connections for treatment plants, and commissioning tests. We work with trusted manufacturers and manage all planning permission and regulatory compliance, ensuring your system meets specific requirements and is fully compliant. Our detailed breakdown of installation costs helps you understand the investment involved, including tank size, material choice such as plastic or concrete, excavation, and landscaping.
Tank Emptying, Desludging, and Cesspit Emptying
Regular septic tank emptying and desludging are critical maintenance services that prevent solid waste buildup, protect your drain field, and avoid system failures. Fastfix offers scheduled emptying and emergency pump-out services using licensed waste carriers, ensuring environmentally friendly disposal in accordance with Environment Agency regulations. We also provide cesspit emptying services, essential for properties with cesspits rather than septic tanks. Our team clears blocked outlet pipes, repairs or replaces soakaway connections, and flushes downstream drains. After each service, we provide desludge records and tailored recommendations for service intervals based on tank capacity, household size, and usage patterns, helping to significantly reduce repair costs and unpleasant odours.
Drainage Field (Soakaway) Design and Installation
A well-designed drainage field or soakaway is vital to the long-term performance and regulatory compliance of your septic tank system. Our team assesses soil percolation rates, site gradients, proximity to surface water and public sewers, and potential obstacles such as tree roots to design soakaways that drain effectively without risk of contamination. Installation includes excavation, stone bed preparation, distribution pipework, and protective covers, followed by landscaping and reinstatement of the surface. We optimise designs to reduce footprint while ensuring longevity and compliance with British Standards and general binding rules.
Condition, Compliance, and Pre-Purchase Septic Surveys
Whether you’re buying a rural property or need evidence your system meets current regulations, Fastfix provides comprehensive septic surveys. Our condition and compliance reports include thorough inspections, system capacity checks, functionality tests, effluent quality sampling where applicable, and photographic evidence. You’ll receive a clear, written report highlighting any urgent repairs, potential issues, recommended maintenance, and estimated repair costs, ideal for conveyancing or planning remediation work.
