A dairy manure handling system is a cost item that must meet many requirements. The ultimate goal of a manure handling system should be to improve management, provide positive environmental protection, and allow maximum utilization of manure nutrients. The best manure handling systems are usually developed as part of an overall plan for new construction, renovation or expansion. A well-planned system will be compatible with the type of housing and will include manure and wastewater from outside animal areas, the milking center, youngstock facilities, and silage effluent. It should also be compatible with anticipated changes in housing and management over the next 8-10 years. An integral part of an effective manure handling system is having adequate cropland available to utilize the manure nutrients or an alternative outlet for extra nutrients. Dairy expansions that include large increases in purchased feed and no increase in cropland often result in over application of manure nutrients. Manure handling systems, especially storages holding large amounts of manure, are a threat to the environment. Any good manure handling system will include backup plans to allow continuous operation even if key components malfunction. Advanced thought should be given to how a large manure spill, resulting from a damaged storage or broken pipe, can be contained before large quantities of manure reach nearby streams or lakes
