Some people live in places where you just cannot dump 5 or 10 thousand gallons of water into their yard. Drainage can be an issue where it goes into a neighbors yard, etc. Without knowing the particulars of a situation it is easier to add those "low cost" grocery store chemicals to solve the problem.
