Drainage and subsidence problems can be some of the biggest challenges any homeowner will ever face. The faults, by their nature, are often hidden from view, making them difficult to detect and put right.

Likewise, a residential property’s water supply system may function perfectly well for many years, before failing suddenly, causing a major flood that can result in serious damage and major costs.

Catalyst has the answer to these challenges with a full range of services to assist home owners with investigating drainage, subsidence and water supply concerns and putting in place high quality solutions.

Domestic property drainage

Drainage problems in residential property can occur in many different ways. For example, they may only emerge gradually as water from a faulty drain seeps into foundations or basements, causing damp, mould growth, structural damage or sudden flooding.

Or a home may be inundated by a catastrophic flood caused by the failure or surcharging of a public sewer or because a nearby water course bursts its banks during heavy rainfall.

Our domestic property drainage services can help identify problems before they occur. If a home is affected by a drainage fault, we can quickly diagnose the cause of that too and put in place robust remedial measures to ensure it does not happen again.

Septic tanks and sewage treatment plants

Catalyst provides a range of services for domestic homeowners whose properties are not connected to the main sewer system and instead rely on septic tanks, cess pools or sewage treatment plants.

These facilities require regular inspection, emptying and cleaning to work effectively and provide long and reliable service. Our services for homeowners with independent sewerage systems include:

  • Septic tank inspection
  • Septic tank cleaning

Septic tanks – general binding rules

Catalyst can help residential home owners who have septic tanks make sure their properties comply with new regulations called general binding rules for small sewage discharge into the ground.

The rules do not allow wastewater from a standard septic tank to be discharged directly into water courses. The Environment Agency (EA) is giving homeowners, and businesses, time to upgrade their septic tanks to ensure they comply with the regulations.

Catalyst can advise domestic homeowners on the most cost-effective plan to upgrade their septic tanks to ensure they are not at risk of prosecution and potentially heavy fines when the new regulations are enforced.

This may involve adaptation and upgrade of the current septic tank system, replacing it with a more advanced sewage treatment plant, or there may now be an opportunity to connect to the main sewer system. Whatever it is, you can trust Catalyst to provide the best advice.
