As a family-run business, you can imagine each department liaising with the other to gain experience & understanding that benefits our customers in a very prudent way, whatever their drainage needs.

That cross over enables us to maintain a fair price for a quality service.

当我们被称为疏通下水道,我们发现that about 70% of callouts are straightforward, unblocked within the first half-hour. When you call someone else, & the blocked drains operative comes across a private sewage system with a pumping station or a cesspit/cesspool, they may not have the knowledge that our team has to diagnose the real problem. This can be difficult, especially if the drains are full & cause further problems.

If the blocked drain person you call has no idea about treatment plants or septic tanks, their ability to solve a problem is limited. They may not have enough knowledge to tell if the system is working or not.


Not only do we have the knowledge & experience to deal with any drainage problem, but we also have all the equipment we might need – either onboard or a short call away.

ASL blocked drains operatives have a lot of experience working with our different departments. This gives them a basic knowledge of a pumping station's workings & how it works. Our operatives know the electrics need to be handled by our qualified electricians. With electricians, managers, expert engineers & consultants from any department on speed dial, it is not a problem. They can ask for their advice after explaining each particular job's problem – or emergency call out. This gives our customers efficient long-term solutions to any drainage issues.


If a sewage tank needs to be emptied, our blocked drain operative can talk to our tanker driver (the emergency tanker driver if needed). They know the tanker driver is reliable & know each other personally because they are part of ASL Limited. Both are also familiar with the workings & the possibilities of the tanker.

Whether you have a private sewage system or not, we can unblock your drain, find the cause & repair the problem too.
