Drainage from ASL Limited

What kind of drainage do I have?

Drains transport wastewater and rainwater away from buildings. Poor drainage setup can lead to foundation issues. If you're unsure about your drainage, call us at 0800 181 684.

Surface Water vs. Wastewater

Properties have two drainage systems: one for surface water (rainwater runoff) and one for wastewater (from bathrooms, kitchens, etc.). Surface water can safely enter watercourses, but untreated wastewater must never be discharged into them to avoid pollution.

Surface Water Drainage

Proper surface water drainage involves guttering and downpipes channeling rainwater safely away. Without a gully surround, overflow can damage foundations, causing cracks or structural issues. ASL can repair or replace gullies to prevent such problems.

Wastewater Drainage

Most homes separate surface water and wastewater. If these aren't properly separated, heavy rains can lead to sewage overflow, affecting the environment. Our experts can assess your setup and advise on any necessary improvements.
