E. MONITORING The following monitoring procedure must be completed on a weekly basis. Written records must be kept regarding the observations of the wastewater management system and domestic water transport system. The following narrative describes the observations that must be performed. Additional observations/testing, etc. may be applicable due to unforeseen conditions: 1. Beginning with the Lift Station for the Manager's Apartment and public restrooms, this tank 1 must be inspected on a semiweekly basis, if it appears that solids and trash are accumulating around the filter screen, a septic pumping service must be called to wash the filter screen and pump this tank. This also applies to the lift station tank that will handle influent from the bar/food preparation area. 2. All of the conveyance PVC piping and PVC tubing must be inspection daily, especially at the joints. When connecting PVC schedule 80 pipe, the maximum procedure for cementation must be followed, which includes using contrasting color primer/cement to ensure proper connections. 3. The observation tubes to be installed on the land-side of the levee to check for leakage of the wastewater/domestic piping/tubing and illustrated on Page 6 of the Plans for this project, must be inspected on a daily basis. As referenced above, since the PVC tubing surrounding the transport piping/tubing is primarily for protection of the levee, it is imperative that written records of the daily observations be kept. 4. The 2,000 gallon septic tank by the schoolhouse should be inspected monthly by a septic system pumping contractor during the spring and summer months. Although most solids and trash will be retained at the aforementioned lift stations, sludge and scum formation should be observed, particularly during the first year of operation. 5. There will be two inspection ports or observation tubes installed within the mound system to observe the sand filter-effluent interface for effluent ponding. Inspection should weekly. The tubes are to be "inverted tees" and be 4 in. PVC. It is imperative that 118 inch screens are on each open end of the tube and that pea gravel rip-rap is placed in front of the screens to prevent infiltration from the sand filter. V. CONCLUSIONS AND RECOMMENDATIONS SSS§ 5.4. The peat soils underlying the proposed mound system disposal area for the new Bullfrog Landing Marina show unacceptable permeability, based upon percolation test results, that create the requirements for a mound system. However, considering direct observation, infiltration and shallow soil permeability readily exist directly after significant rainfall. Additionally, the comparatively shallow depth to the water table also requires a mound system. r 18 r Chesney Consulting
