Use flashlight to detect sediment deposits <br /> iii. If present, measure sediment depth with stadia rod <br /> iv. Record results on Maintenance Log <br /> v. Replace Cap <br /> b. Maintenance Port/s <br /> i. Remove Cap <br /> ii.Use flashlight to detect sediment deposits <br /> iii. If present, measure sediment depth with stadia rod <br /> iv. Record results on Maintenance Log <br /> v. Replace Cap <br /> vi. Repeat for ALL Maintenance Ports <br /> c. Adjacent Manholes <br /> i. Remove Cover <br /> ii. Use flashlight to detect sediment deposits <br /> iii. If present, measure sediment depth with stadia rod, accounting for depth <br /> of sump (if present) <br /> iv. Inspect pipes connecting to R-Tank <br /> v. Record results on Maintenance Log <br /> vi. Replace Cover <br /> vii. Repeat for ALL Manholes that connect to the R-Tank <br /> 2) Maintenance <br /> a. Plug system outlet to prevent discharge of back-flush water <br /> b. Determine best location to pump out back-flush water <br /> c. Remove Cap from Maintenance Port <br /> d. Pump water as rapidly as possible (without over-topping port) into system until at least <br /> 1" <br /> of water covers system bottom <br /> e. Replace Cap <br /> f. Repeat at ALL Maintenance Ports <br /> g. Pump out back-flush water to complete back-flushing <br /> h. Vacuum all adjacent structures and any other structures or stormwater pre-treatment <br /> systems that require attention <br /> i.
