"Since that first 12 months it has been all go," says Davieth.
"Each year we have secured the Landcorp new Dairy Effluent Systems contract.
"This is a competitive tender that has been occurring for the past five years and we are now on to farm number 15.
"This is something we are very proud of."
In addition AgFirst Engineering Waikato has become thoroughly involved with Spring Sheep Dairy, completing their first dairy sheep effluent system for 4000 ewes in Taupo and are currently involved with two local sheep milking farms.
Davieth says it is et's exciting times at AgFirst Engineering.
"In 2016 we moved in to our new, larger Bond Road workshop and this year we welcomed Kerry Perrett to join the team.
"We searched far and wide for our next team member and are pleased to welcome Kerry aboard.
"Having experience and skilled people in our team is our number one priority."
Another key success in the AgFirst Engineering portfolio was the development of the Weta travelling rain gun effluent irrigator.
The irrigator has been designed to achieve the highest efficiency.
It can achieve the largest flows and wetted area over any other irrigator with the least amount of pressure meaning less pumping hours, less labour and less wear and tear.
The key feature is the turbine driven hydraulic winch system and automated speed control.
The Weta was chosen as the irrigator of choice for the Massey University Research Farm, as well as being rolled out throughout Landcorp farms.
So where to from here?
Davieth sees a very bright future for AgFirst Engineering, with the recent signing of a national contract for the design and supply of effluent monitoring solutions for Landcorp's 60 dairy units.
This includes monitoring all aspects of the effluent system including pond levels, flow rates, weather stations, soil moisture monitoring, GPS location, travel speed and operating pressures.
All this data is then mapped automatically showing application depths, wetted widths, and nutrient application data.
In addition to all of this work the AgFirst Engineering team is involved with many local projects.
"Stock water reticulation is also a large part of our business, we can complete full water system design and build from the water source through to the ballcock," says davieth.
"We have over 100km of water pipeline being installed throughout the North Island."
And what has been on the cards recently?
"We installed a custom built solar powered water pumping system in Marton for dry stock water supply.
"The pump is a submersible progressive cavity which will be pumping a static lift of 150 metres.
"We love our job."
