Beware the Bargains:  Why Cheaper Isn't Always Better.

See how Evoloution fixed this drainage disaster...



We found Clinton and Pete by chance when looking for specialists to replace a very old (and failing) septic tank as we started to renovate our home.


When we first met Clinton and Pete we were struck by their professional knowledge and experience in installing water treatment systems. Both took time to explore options for our needs and took time to understand the site before commencing any work, it was reassuring not to feel pressured and no question appeared too much to answer.


When work started we were both amazed at how tidy the work was completed with minimal disruption to the family as we remained living in the house. Clinton and Pete’s work ethic also came through as they worked on site for around 10 days through wind and rain and rarely stopping for breaks.


In total Clinton and Peter removed the old systems, installed a new water treatment system, soakaway and also relined existing pipe work – leaving us with essentially a new sewage system for the house.


Thanks both for everything!
