Unified Excellence in Drainage: The ASL Advantage
At Amalgamated Services Limited (ASL), we’ve taken a bold step toward redefining efficiency in the drainage industry. By merging seven specialised departments into one cohesive entity, we’re fostering a culture of innovation and excellence while delivering comprehensive drainage solutions to our clients.

Why Merge Seven Departments?
Each department within the drainage industry offers unique expertise, from handling main drain connections to managing pumping stations. By bringing these divisions together, ASL provides:
- Holistic Services: No need to coordinate between multiple contractors – we cover everything.
- Shared Expertise: Our team members access insights across departments, resulting in more effective solutions.
- A Unified Vision: We’re committed to innovation and the highest standards of service.
Specialist Services, Unified Strength
The drainage industry demands expertise in various niches. Here’s how we specialise:
- Main Drain Connections: Our experienced team holds the certifications and training necessary to work safely and efficiently on public roads.
- Pumping Stations and Treatment Plants: These require specific electrical certifications and deep technical knowledge, all of which our team possesses.
By uniting our departments, we enable our engineers to cross-train and gain knowledge of systems such as septic tanks, pumping stations, and treatment plants.
Customer-Centric Efficiency
At ASL, we know that time is valuable. Our streamlined approach ensures:
- Faster Resolutions: Optimised processes mean quicker turnaround times.
- Tailored Solutions: We identify and address specific needs, whether it’s a blocked drain or a complex treatment plant issue.
- Expert Guidance: Our engineers bring years of experience to every job, ensuring reliable, professional service.
Private Sewage System Expertise
If your property isn’t connected to a public sewer, you might need a cesspit, septic tank, or sewage treatment plant. ASL offers expert advice to help you choose the best option:
- Cesspits: Underground holding tanks that require regular emptying.
- Septic Tanks: Multi-chambered systems treating sewage through natural processes.
- Sewage Treatment Plants: Advanced systems producing clean, non-polluting effluent.
Each system comes with specific maintenance needs. Learn more in our blogs:
When you choose ASL, you’re partnering with a team that cares about quality, reliability, and your peace of mind.
