Advantages
Each Larall system has sprinklers in each paddock within the effluent block. Depending on the Larall system there is a sprinkler that looks after either .6 or 1 ha. In a 3 ha paddock there would be 5 sprinklers for a Larall One and 3 for a Larall Two.
• Low application rates (Larall One, 3.5mm, Larall Two, 5mm)
• Large volumes pumped per hour (starts at 36m³)
• Low labour content (less than 3 hours a fortnight)
• Designed to suit volume and labour requirements
• Sprinklers stay in each the paddock
• Easy to move
• Eliminates ponding
As a low rate system it deserves a look as an option.
Disadvantages
The sprinklers are left in the paddocks. There can be damage to the sprinklers by running them over, until you are used to then being there. The capital cost can be higher than other options.
Things to consider
Because of the ability to design the system on volumes pumped and low labour, there are systems that are pumping over 120m³ an hour and as little as 5 hours labour a month. The system can be installed onto step and rolling land.
PTO pumps are a good option because of the volume pumped per hour and the cost can be a lot less than setting up with an electric option.
