<p>My teacher assigned us a problem from last years test, specifically on the sewage treatment question. Does anyone know the answers to it?</p>
<p>I suspect she wants you to come up with your own answer.</p>
<p>Haha these are for practice, not a grade. I've done the first three parts but can't get the part about alternative methods to treat sewage.</p>
<p>Ha, Ha, practice doesn't help if you don't do it yourself. ;)</p>
<p>Google "alternative sewage treatment" and you'll get a ton o' hits.</p>
<p>Thanks. 10char</p>
