Recycle pit, tailwater storage pit
A recycle pit is a structure designed to capture irrigation run-off (known as tailwater) for re-use in the production area. If designed, sited and operated correctly recycle pits can have significant water quantity and quality benefits by ensuring tailwater, and any associated sediments, nutrients and pesticides, are re-used on the farm and do not enter natural waterways and wetlands.
Unlike many other treatment systems used in agricultural production systems recycle pits do not treat the water. Rather they rely on the water being captured and re-used on the farm. They are also included as a farm best management practice.
Recycle pits are generally used in areas where surface furrow irrigation is used. This is primarily in sugarcane and broadacre cotton and grain crops. Recycle pits are designed primarily to capture irrigation tailwater, but can also capture some stormwater run-off in irrigated cropping areas.
