Sherriff Drainage 

Sherriff Drainage has been in the industry for many years, specialising in subdivisions and larger diameter pipe work. The director of the company Jason Sherriff has also competed in excavator competitions in the Auckland area with winning the first one in 1999 then won in 2002 & 2004 and going on to compete at the nationals. Jason bought into the company in 2000 with his father Kelly, who is a prominent figure in the drainage game having been in it for over 35 years, Jason then took over the company in 2002.   

The manufacturing yard is based in Drury, Auckland with close access to  the southern and northern motorways to  make pick up and delivery as  easy as possible.

The Sherriff Bencher

Jason came up with the idea of the Sherriff Bencher in 2007 after  thinking there must be an easier way to bench and plaster manholes. The polyethylene liner was placed into a flanged base manhole you would then have to connect the pipes and seal them off.  With the Done Manhole, we have gone to the  next level with a high strength concrete base and the required pipes on grade and direction to suit the job.
