Meet the wastewater team

Alastair-optimized-969 clayton-optimized 2-789
Alastair Lewis
Clayton Lewis
Allflow wastewater consultant Sales consultant and technical advisor

Alastair has been working in the wastewater field for more than 40 years, starting out in 1977 when the Lewis family ran a septic tank cleaning operation with vacuum tankers.

Alastair says he’s seen major changes in new products and technology over the years, but reckons the biggest change was when on-site wastewater treatment systems for houses and businesses came on the market (as opposed to the old septic tank and soak pit that was not a very successful solution especially in clay.)

Alastair says the Allflow team makes sure they are up to date with the very best and most sustainable wastewater products available on the market. “We research around the world, at trade shows and through our contacts in the industry, and we always look for quality in whatever we provide to our customers.”

Clayton is the problem solver on the Allflow team and that’s the way he likes it. When there’s a particular customer request that’s a bit out of the ordinary, it’s often fired through to Clayton for resolving.

“It’s rewarding sorting out the right solution for people – finding the best product or customising equipment for people’s specific needs,” he says. “Where there’s a bigger project or a higher degree of complexity, I tend to get involved.”

Providing both technical and sales support at Allflow, Clayton works mainly in the wastewater and vacuum parts of the business, as well as assisting customers with pumping equipment in the shop.
