Subsurface application equipment includes tractor-drawn tank wagons with injection shanks or tank trucks fitted with flotation tires and injection shanks. Dewatered sludges require handling equipment similar to that used in applying animal manures, limestone, or solid fertilizers.
Dewatered sludge is typically surface applied and then incorporated by plowing or disking.
The following table lists the equipment that is available from DEQ for use by municipalities for one time sludge applications. Applicants are encouraged to allow for delays in scheduling equipment when developing their sludge plans. Applicants are responsible for all maintenance and operation.
