Sprinkler irrigation over the mound system must be carefully considered so as to not inundate the disposal area. During the spring and summer months,irrigation should be done intermittently during the day and/or evening-hours. For example,the sprinklers could run for five minutes,six times per day. Irrigation during the wintertime abould btsuspended. Another source of nitrate loading can be from the lawn grass that may be planted over the mound system area. It is recommended not to use any nitrogen fertilizer over the mound system. Accurate"as-builts"of the septic system installation must be supplied to the Environmental Health Department by the septic system contractor/installer. All applicable"distance"and"setback"requirements must be strictly followed. It is imperative to recognize that all septic systems and disposal areas have a lifespan. This lifespan is unpredictable due to the numerous operational and environmental factors involved. A critical lifespan issue is controlling the on-site water use as much as possible. Water flows must be at an absolute minimum. The control panel for the quad pump system will total the volume of wastewater pumped and consequently the volume of domestic water used. If this volume exceeds the calculated ADF of 2,400 gpd, adjustments must be made to on-site water usage. Restricting water use also includes checking.for water leaks in toilets, dripping faucets,etc.on a regular monthly basis. VI. LIMITATIONS The findings,opinions and conclusions of this report are based upon information from standard engineering and analytical test procedures,contemporary scientific literature and agency consultations. Information in this report is deemed reliable by the sources from where it was obtained. Results of the percolation testing should be assumed to only represent the subsurface conditions encountered in the specific area of testing and not of the entire proposed mound system area to serve the expansion of the Gurdwara Gur Nanak Parkash Sikh Temple. The specific design components for the Temple's domestic wastewater disposal system are subject to change. This report is based upon current scientific knowledge to assess factors which are extremely variable and complex within the environment. Although there are several methods to size and predict environmental impact from a septic system,San Joaquin County Environmental Health Department Sewage Standards and requirements have been employed for these purposes,and for this project. Therefore,no guarantee or warranty concerning any aspect of this report or design,is expressed or implied. The opportunity to provide this service for you is appreciated. If there should be any questions regarding to the information contained within this report,please contact the undersigned.
