Section 7103-24.0 - Land Requirement24.1 After the wastewater has been analyzed for appropriate constituents and the site assimilative capacity for those constituents determined, the amount of land needed for environmentally sound wastewater application can be calculated.24.2 The quantity of each wastewater constituent generated per year is calculated using annual wastewater generation rate and constituent concentrations. These values divided by the annual site assimilative capacity yield the land area required. After the area required for each constituent is determined, the limiting constituent, i.e., the constituent requiring the most land, determines the amount of land needed for the land treatment system.24.3 Hydraulic loading is often the limiting factor with municipal wastewater. Typically, the amount of land required for 1 M gal/d of wastewater based on hydraulic loading may vary between 120 and 300 ac. depending upon the hydraulic properties and management of the site. After the area required for actual application is determined, additional area for buffer zones must be determined.7 Del. Admin. Code § 7103-24.0
