The length of the level spreader should be determined by the type of filter area and the design flow:

* 1.4 m of level spreader length per every 0.01 m³/s of inflow for discharges to a [[filter strip]] or grassed area;

* 1.4 m of level spreader length per every 0.01 m³/s of inflow for discharges to a [[vegetated filter strips|vegetated filter strip]] or grassed area;

* 4.3 m of level spreader length per every 0.01 m³/s of inflow when the spreader discharges to a forested conservation area.

* 4.3 m of level spreader length per every 0.01 m³/s of inflow when the spreader discharges to a forested conservation area.

* The minimum level spreader length is 4 m and the maximum is 40 m.
