Septic Tank Emptying & Desludging

Fast, licensed waste removal for septic tanks, cesspits & treatment plants. Same-day attendance, 24/7.

Septic tank emptying & desludging.

When to choose this service

Choose septic tank emptying if toilets are slow to flush, you notice odours around covers or drains, the high-level alarm has triggered, there’s surface pooling near the soakaway, or your scheduled collection is overdue. We service septic tanks, cesspits/cesspools and sewage treatment plants at homes, farms and commercial sites.

Regular desludging (typically every 6–12 months, usage-dependent) prevents overflows, blockages and pollution incidents — and keeps you compliant for Environment Agency duty of care.

Why Drain Alert

We deploy jet-vac tankers to remove sludge and scum, jet-wash inlets/outlets and chambers, and recharge to the correct operating level. We check baffles/tees, pump chambers and alarms, and can clean connecting pipework and gullies. For treatment plants, we reinstate air blowers and confirm flows.

You’ll get before/after photos and a Waste Transfer Note for every collection. Work is carried out by accredited engineers, scheduled 24/7 with no call-out charge. If we find a defect (e.g. damaged baffle, collapsed outlet or soakaway issues) we’ll explain options and provide a free, fixed quote for any remedial works.

Assess & position

24/7 attendance with no call-out charge. We agree RAMS, locate covers and safe access, protect work areas and confirm the disposal route.

Empty & wash down

Jet-vac removes sludge and scum; we jet-wash internal surfaces, inlets/outlets and pump chambers. We can flush connecting lines to restore free flow.

Check & reinstate

We check baffles/tees, alarms and blowers (where fitted), recharge to the correct level and reinstate lids and seals for a clean, odour-controlled finish.

Verify & schedule

We supply before/after photos and a Waste Transfer Note, then recommend service intervals and can set up planned maintenance to prevent callouts.
