We were called out to this home because water was collecting at a low spot in this yard and making part of this yard unuasble. Because of grade restraints there was no way to collect the water and pipe it to an exit point. NDS Flo wells were stacked on top of each other creating a place for the water to go . We also used NDS ez flow drains and additional clean stone to add to the water holding capacity. Installing a dry well will create underground porous holding area that will temporarily hold water so that it can seep into the soil.
