Case Study: PM01

Location: Orini

Cows: 300 Spring Calving

Brief/Description:

• Existing storage ponds were too small and not sealed to required standard
• No stone trap leading to a lot of grit/stones in the existing pond
• Old style irrigator over applying effluent

Solution:

Ran through a number of scenarios in the Massey University dairy effluent storage calculator which revealed upgrading the irrigation system dramatically reduced the size of the pond due to increased number of irrigation days available and higher system flow rate. Other contractors were used to de sludge the existing pond, re construct to required dimensions & line with HDPE synthetic liner.

Installed a new suitably sized shore mount pump & stirrer, extended irrigation lines & upgraded irrigator to a low rate traveller

Installed concrete stone trap & Williams 3 x 6 x 1.4 meter tailings bunker
