Note if the pool excavation contractor or other such excavator will haul away that dirt for you, or if you would need to call a removal service to pick up this dirt after the excavation. In some cases, you might get a monetary credit for that dirt, as landscaping companies might resell it, so be sure to ask what happens with it and if you get credit for it. 3 In the same way, note if the excavation company will replace that dirt over pieces such as a septic tank or plumbing pipe.
