4.4 STORMWATER DRAINAGE
Issues relating to surface flows may become prevalent within the disposal areas during

extended periods of rainfall. Accordingly, it is recommended that a cut-off drain or diversion

drain/mound is constructed upslope of the disposal areas to collect and divert any

surface/subsurface waters away from the disposal area. A retention mound is to be

constmcted downslope of the land application area to prevent any surface water from exiting

the designated disposal area.



All stormwater runoff from the roof of buildings and pavement areas associated with the

development on the site should not be discharged in a concentrated form onto the effluent

disposal areas.
