A homeowner who has access to a communal sewage system or waste disposal system will not need a sewage field. However, as you are more and more moved away from the adjustable sewer system, this will be a question for you. The contractor will be able to offer you the paths by which you can proceed to the construction of a septic drainage field, and will also contact people qualified to fulfill this requirement for you in accordance with the standards and requirements of the local community.
