<Li> Tertiary treatment is sometimes defined as anything more than primary and secondary treatment in order to allow ejection into a highly sensitive or fragile ecosystem ( estuaries , low - flow rivers , coral reefs , ... ) .

If it is sufficiently clean , it can also be used for groundwater recharge or agricultural purposes . </Li>
