Yes it´s true! How so, in an urban setting?

Our potencial LEED ND project that is situated in a small city within the metropolitan area of Recife, capital and largest city of the Brazilian State of Pernambuco, is facing this issue.

The project team is working on mapping out the “nearest” sewage system in order to prove that it’s miles and miles away… Connecting the project to public sewage infrastructure is completely unviable. So this would mean that no new project in the entire region can be LEED ND certified? The pre-requisite serves to encourage smart site selection, but in this case it’s just not a case of selecting; there are no areas to choose from in the entire city that would achieve the pre-requisite per se.

So as we see it, it’s a matter of responsibility. In this light, the developers plan to treat and reuse graywater and blackwater onsite, besides using efficient flush fixtures in order to reduce the volume of water used for sewage conveyance in the first place. Rainwater will be treated and used onsite by buildings as well. For potable water, an onsite water treatment plant will treat groundwater from nearby wells to potable standards.

Is this approach acceptable in order to achieve the prerequisite, given the regional conditions? Somebody have any suggestions or approaches that you see more fit?

Our project team is concern about registrate the project and submit a SLL prerequisite review without a official response for this issue.

Thanks in advande for any help
