Excellent service. Andy was most helpful with finding the problem with our septic system, ordering and replacing the broken part, and arranging for the tank to be emptied as an emergency.Andy went out of his way to prioritise our job as an urgent fix needed. Also offered helpful advice on how to maintain and improve our existing system. Excellent communication throughout, friendly and reliable service.

Frequently asked questions
We inspect, test, install, repair and maintain private sewage systems and a range of storage tanks. Our services include septic tanks, sewage treatment plants, wastewater percolation testing, surface-water soakaway testing, rainwater harvesting systems and water, heating oil, LPG and diesel tanks.
Yes we can. We carry out septic tank inspections and more detailed homebuyer surveys to help identify visible defects, poor performance, drainage-field concerns and other issues that may affect the property. We’ll explain what we can inspect, what we find, what the costs are and whether anything needs further investigation.
Yes, but they are different tests. A BS 6297 wastewater percolation test assesses ground intended for a drainage field serving a septic tank or sewage treatment plant. A BRE 365 soakaway test assesses how surface water, such as rainwater from roofs and paved areas, can infiltrate into the ground.
We can inspect the tank, treatment plant, accessible drainage and surrounding ground to look for visible damage, poor flow, leaks, ponding and other signs of failure. Depending on what we find, the next step may involve servicing, repair, further investigation or replacement.
We install private sewage systems for homes, businesses and development projects. The work required will depend on the property, available ground, proposed discharge arrangement and whether site testing, drainage-field design or other preparatory work is needed.
Tankology works on private homes, property transactions, commercial premises, developments and larger sites. The scope can range from a single inspection or test through to a complete tank or treatment-system installation.
Most of our work is carried out across South Wales. Selected inspection, survey and testing services are also available elsewhere in Wales and parts of western England. Send us the site postcode and a brief description of what you need, and we’ll confirm whether we cover the location.
