Sprinkler irrigation over both disposal areas must be carefully considered so as to not inundate the <br /> leachfield. During the spring and summer months, irrigation should be done intermittently during <br /> the day and/or evening hours. For example, the sprinklers could run for five minutes, six times per <br /> day. Irrigation during the wintertime should be suspended. Run times and number of daily <br /> irrigations should be determined by the landscape contractor. <br /> Another source of nitrate loading can be from the lawn or other landscape-type plants that may be <br /> planted over the leachfield area. It is recommended not to use any nitrogen fertilizer in these areas. <br /> If it is deemed necessary to use them, "slow release"nitrogen fertilizers should be used on the lawns <br /> and/or landscaping to reduce nitrate loading from these areas. <br /> Accurate"as-builts"of the septic system must be supplied to the Environmental Health Department <br /> All applicable"distance" and"setback"requirements must be strictly followed. <br /> It is imperative to recognize that all septic systems and disposal areas have a lifespan. This lifespan <br /> is unpredictable due to the numerous operational and environmental factors involved. A critical <br /> lifespan issue is controlling the on-site water use as much as possible. This may be accomplished by <br /> using low flow toilets and spring-loaded sink faucets. Restricting water use also includes checking <br /> for water leaks in toilets, dripping faucets, etc. on a regular basis. <br /> 15 <br /> Chesney Consulting <br />
