Determine how many wastewater pipes exit the base- ment and that all are properly connected to an approved wastewater disposal system such as a sewer line, septic system, or overboard discharge unit. Check that the wash- ing machine is also connected to the wastewater system and not illegally routed to the lawn or storm drain network, and that sump-pumps and foundation drains are not routed to the wastewater disposal system. These devices can overload the system causing back-ups and/or hydraulic problems; therefore, they should be routed to a dry well, or to the ground surface,57 or if they contain only clean water they can legally be discharged to surface waters.
Conducting the Sanitary Survey
For storm drainage networks, dye testing is most use- ful when the drainage area is small and communication with local agencies is necessary to avoid the dye being mistaken for a spill or another contaminant.
Every identified problem is a violation that should be eliminated. The DEP has overlapping jurisdiction and authority with the municipality where wastewater disposal systems discharge to surface and ground waters. All problems should be brought to the attention of the mu- nicipality and the DEP and need to be eliminated if water quality and public health are to be protected (see Part IV).
