Septic Tank Emptying & Waste Disposal

Septic Tank and Cesspit Emptying in West Sussex and Hampshire

Septic tanks and cesspits collect wastewater from properties not connected to the mains sewer. To keep them functioning efficiently and avoid costly damage, regular emptying and maintenance are essential.

If your tank is full, it can lead to unpleasant odours, slow drainage, and even system failure. At West Sussex Drains, we provide professional, reliable cesspit and septic tank emptying services across West Sussex and Hampshire, ensuring your system remains in top working condition.

Signs Your Septic Tank or Cesspit Needs Emptying

  • Slow drainage: Sinks, toilets, and baths draining more slowly than usual.
  • Unpleasant odours: Bad smells coming from your drains, tank, or surrounding area.
  • Pooling water: Water gathering near the tank, cesspit, or drainage field.
  • Gurgling sounds: Unusual noises from pipes when flushing toilets or running water.
  • Overflow or backups: Wastewater backing up into sinks, toilets, or outside the tank.

If you notice any of these signs, contact us to schedule a professional emptying service.

How Often Should They Be Emptied?

Septic tanks usually need emptying every 6–12 months, while cesspits require more frequent emptying, sometimes every few weeks. The exact timing depends on the tank size and household usage.

Our Emptying Service

Our septic tank and cesspit emptying service is fast and efficient, using specialist vacuum tankers to remove waste quickly and safely. We ensure eco-friendly disposal by handling waste responsibly and in full compliance with environmental guidelines.

If your system is overflowing, our 24/7 emergency callout service is available to provide urgent assistance. Our expert team can advise on the best maintenance schedule to keep your system running smoothly. Under the General Binding Rules, regulations now require septic tanks to discharge into a proper drainage field rather than surface water or streams. If your system does not comply, we can guide you through the necessary upgrades or replacements to meet legal requirements.

Avoid Environmental Damage

Both cesspits and septic tanks can cause pollution if they are not emptied regularly. An overflowing cesspit may leak harmful waste into the surrounding soil and water sources, posing health risks and damaging the environment. Septic tanks that are too full can also lead to untreated wastewater escaping, contaminating nearby land and waterways. Routine emptying and maintenance are essential to prevent leaks and ensure compliance with environmental regulations.

We hold a waste carrier licence so you know your waste is disposed of in a safe and legal way.

Frequently Asked Questions About Cesspits and Septic Tanks

How Do Septic Tanks Work?

Septic tanks collect wastewater from your property, separating solids from liquids. The solids settle at the bottom, while the liquid flows into a soakaway or drainage field. Over time, sludge builds up and needs to be removed to prevent blockages, overflows, and damage to your system.

How Do Cesspits Work?

A cesspit is a sealed underground tank that collects and stores wastewater and sewage from properties not connected to the main sewer system. Unlike a septic tank, it does not process or treat waste; instead, it simply holds it until it is removed by a licensed waste disposal service. Because it has no outlet or drainage system, cesspits must be emptied frequently to prevent overflow and environmental hazards.

What is the Difference Between a Septic Tank and a Cesspit?

A septic tank separates solids from wastewater, allowing liquids to drain into a soakaway system, reducing waste buildup. A cesspit, on the other hand, is a sealed tank that simply stores waste and requires frequent emptying.

Do I Need Installation Permission?

Yes, installation must comply with UK environmental regulations, and planning permission may be required in some areas. It’s best to check with the local authority before installation.
