Operation and maintenance considerations include fine tuning of the application cycle, vegetation harvesting, and maintenance of the slope and runoff collection channels. Pest control must consider mosquitoes and invasions of army worms (WEF, 2001). Periodic mowing of the cover grass is necessary to maintain a healthy stand of grass and reduce bunching. A minimum of four mowings per year is recommended. The slopes should be dried completely before harvesting.
Soil aquifer treatment (SAT) has the highest hydraulic loading rate of any land treatment system. The site selection criteria for SAT are also more stringent. Design objectives, site selection procedures, treatment performance, design considerations, construction considerations, and operation and maintenance for SAT systems are described in this section.
