Experience & expertise
If your home is not connected to a mains sewer system, a septic tank is one of the most reliable ways to manage wastewater.
At Trent’s Drains, we provide full domestic septic tank services across Bristol, Reading, Bath, Cardiff, Newport, Gloucester, Swindon, Chippenham, Weston-super-Mare, Taunton, Somerset and Wiltshire.
Our services cover installation, maintenance, emptying, repair, inspection, and advice to ensure your system remains safe, compliant and efficient.
Septic tanks are underground wastewater treatment systems that collect household sewage, separate solids from liquids, and discharge treated effluent into a drain field or soakaway. When properly installed and maintained, they can last many years.
However, without regular care, many problems can arise – overflows, backups, foul odours, contamination of ground or surface water, and system failures. Neglected tanks may violate environmental regulations, especially under the General Binding Rules (GBR) in England & Wales.
Routine maintenance, timely repairs, and correct installation are essential to protect your property, health, and the environment.
We offer a comprehensive domestic septic tank package:
We evaluate ground conditions, percolation, proximity to watercourses, and suitability for soakaway or drain field.
Based on number of occupants and waste load, we size the tank and field accordingly.
Excavate, position the tank, connect pipework, test for leaks, backfill and commission the system.
Depending on usage and system size, we schedule emptying every 3–5 years or more frequently if needed.
We check the health of the tank and field - look for damp spots, slow drainage, odour or overflow signs.
If parts are failing, we restore them - repair cracks, upgrade lids, replace worn components or even upgrade to treatment plants where required.
We issue documentation and advisory reports so your system is audit-ready and traceable.
Watch out for these warning signs:
If any of these occur, prompt inspection and remedial action can prevent serious damage.
With local teams, we offer fast response, regional knowledge of soil types and local regulations, and scheduling flexibility suited for your location.
A well-maintained septic system is a safer, cleaner, more sustainable solution for homes off mains sewer.
Upgraded an aging concrete tank’s lid and replaced failing pipework, extending system life without full replacement.
Performed routine emptying and inspection — removed sludge, sealed minor leaks, and restored performance without system replacement.
Installed a modern fibreglass septic tank and soakaway system, tailored to restricted ground space.
Typically every 3-5 years, depending on usage, tank size and load. Larger households or heavy use may require more frequent emptying
In England, systems must comply with the General Binding Rules (GBR). Installation of new or altered systems may require permits or planning permission.
Septic tanks provide primary treatment (settling solids), while treatment plants have additional biological or mechanical processes to clean effluent more thoroughly. They often require power and maintenance
Costs vary by tank size, location and access. But periodic service is far cheaper than emergency remediation or full replacement
Yes—lids, baffles, seals, pipes or tank structure can degrade. We inspect and repair to avoid total system failure.
