We have proposed storm water pipes with perforations on Top half of the pipe periphery. The ground water table is below the pipe profile and with a minimum separation distance of 1.5m. The only source for infiltration is due to extensive landscaping water percolating into ground. How do I input an infiltration rate (say 10% of landscaping demand) along the SW pipe routing. Similarly, how do I model the ground water infiltration rate from pond storage with a separation distance of 1.5m between Pond bed and water table underneath it.
