Authority to inspect and approve the installation of building sewers
and their connection to the public sewer system.
NATURAL OUTLET

Elimination System for the discharge of wastewater into the waters
of the state, issued pursuant to Section 402 of the Clean Water Act,

include depreciation and replacement costs).
PERSON
Any individual, firm, company, association, society, or its
corporation, trust, estate, group, or other legal entity, or its representatives,
agents, or assigns.
pH
The logarithm of the reciprocal of the concentration of hydrogen
ions expressed in grams per liter of solution.
PRETREATMENT
The treatment of extra strength wastewater flows in privately
owned pretreatment facilities to a less harmful state before discharging
