The System's Performance
Under the conditions set forth
in the Ohio EPA Permit to Install, the effluent
quality of the system must be tested monthly
by an independent laboratory. Monitoring the
effluent quality involves testing for the following:
CBOD5, total suspended solids, fecal Coliform
bacteria, residual chlorine, pH and flow to
the drip dispersion system. The on-site system
went into operation in February 2003, and testing
indicates that the system is performing as designed.

A flow meter monitors the total
gallons of effluent discharging to the drip dispersion
system. The average daily flow to the drip dispersion
system between March and July was 260 gallons.
