Waste Water Treatment & Liquid Waste Management
Removal, treatment and compliant disposal, nationwide
Construction sites generate water they didn't plan for, groundwater in excavations, rainwater in open digs, wheel wash and concrete washout, and silt traps or interceptors that quietly fill until they overflow. None of this can be discharged into drains or watercourses without consent and leaving it in place stops work.
“None of it can simply be pumped into the nearest drain or watercourse…”
We provide nationwide removal, treatment and compliant disposal of wastewater and liquid waste, with full documentation so your duty of care file is complete.
What we handle
“When water stops the job, the job stops costing money the moment it is cleared.
- Site dewatering: Groundwater and standing water removed from excavations, basements and shafts. Silt laden water is treated, not relocated.
- Interceptor & silt trap emptying: Fuel and oil interceptors, silt traps, catch pits and drainage systems emptied, cleaned and inspected.
- Wash water & washout: Wheel wash, concrete washout, plant washdown and yard runoff, high solids, high pH, unsuitable for surface water drains.
- Tank, chamber & pit emptying: Septic tanks, cesspits, holding tanks, pumping stations and underground chambers.
- Liquid waste removal: Hazardous and non hazardous liquid waste tankered to licensed facilities.
- Treatment: Settlement, separation, filtration and pH correction.
- Emergency response: Flooded excavations, blocked systems, pump failures and spills.
Compliance managed properly
Wastewater and liquid waste are controlled wastes. Incorrect discharge, to drains, ground or watercourses, is an offence. We ensure:
- Correct classification
- Licensed carriers
- Permitted receiving facilities
- Waste transfer notes (non hazardous)
- Consignment notes (hazardous)
- A clear record of where every load went
Planned maintenance over emergency callouts
Interceptors and silt traps fail the same way every time: they fill slowly, go unnoticed, then overflow during heavy rain, often at weekends and often onto something critical.
“They fill gradually, nobody notices, and then they overflow…
A planned emptying schedule costs far less than emergency response or pollution incidents. We can maintain a single site or an entire estate, flagging issues before they become problems.
One load or a national programme
Whether it's a single tanker for a flooded excavation or scheduled liquid waste management across multiple regions, we handle both. Contractors working nationally avoid juggling multiple suppliers, rates and standards.
Because we also supply aggregates and run muck away, materials in, spoil out and water off can all sit with one supplier and one point of contact.
Frequently Asked Questions
Almost never. Surface water drains discharge directly to watercourses. Foul sewer discharge requires consent; controlled waters require a permit.
Tell us the situation and location, emergency callouts are treated as genuine emergencies.
Waste transfer notes, consignment notes and receiving facility details, everything required for duty of care.
Yes, subject to classification.
More often than most sites expect. We'll assess and recommend a realistic cycle.
