What must be done in addition to using alternate lateral fields on certain sites?

In the context of using alternate lateral fields on certain sites for septic systems, meeting all special design requirements is crucial. This is because alternative systems often have specific guidelines and standards that must be adhered to in order to ensure their effective operation and to mitigate environmental impacts. These requirements can include factors such as soil characteristics, site topography, and local regulations, all of which play a vital role in the design and installation of septic systems.

By following these special design requirements, you ensure that the alternative lateral fields function properly and provide adequate treatment of wastewater. This also helps prevent issues such as system failures or contamination of surrounding areas, which can occur if a system is improperly designed or installed.

Other options may not necessarily align with the specific focus of alternate lateral fields. For example, implementing a new drainage system or installing additional tanks might be relevant in different contexts, but they do not specifically pertain to the unique considerations that come with using alternate lateral fields. Similarly, reducing system size could lead to inadequate treatment capacity, which contradicts the aim of providing a properly functioning septic system. Thus, adhering to special design requirements is fundamental when utilizing alternate lateral fields.
