Round up the design flow to the next 5 0 gpd value. For instance, a 600 gpd design flow wilt need 2 aerators (600 gat. ,ounded up to 1000 gal. needs 2 aerators). The aerator box ca i be installed in two ways. First option is to install the aerator box so that the bi atom of the aerator box is at the same elevation or higher than the top of the tank risers, see Illustration 3. If the site is sloped the aerator box can be buried upslope from the tanks. Second option is to install the aerator box with the lids f the box and risers at the same elevation. The sides of the aerator box lid must n t be buried. Aerators can be installed up to several hundred feet away from tie diffusors. The line between aerator and diffusors must slope toward diffusors. Aesthetic concerns hould be considered when placing the aerator box. Place the aerator away from house windows, doors, and areas where people tend to congregate, such as pathos areas and barbecues. �;' �I•. tic y, � O CINDY E.WAITE �r.,' LICENSED DESIGNER EXPIRES CS;T'i Headworks, manual ' lush: HWN.,7.man inches Arkal[disc filter, mesh, 130 micron • 3 inches Arad jf qw meter • Three oil filled ressure gauges (0-100 psi) • One 1 inch Spears gate valve for flushing.

There may be a de ire to cover the OSCAR with something additional to the specified ASTM C-33 sand The intent is not to have too much additional cover over the final C-33 sand layer hat would prevent the sand from accessing oxygen from the atmosphere. Placing oo much cover will inhibit plant root growth. Because the C-33 sand is sub-surf e irrigated, grass and other ground cover will grow rapidly, forming a firm p otective cover over the OSCAR. At the end of the first growing season the C-33 sand layer will be as firm as native soil to walk on. Options include: • Landscaping jute mats ith grass seed or ground cover plantings • A thin layer of mineral oil low in organic content (<10% organics) • Thin layer of crushed o washed rock for wind erosion protection. • Thin layer of bark to w od chips. • Aggregates the size of ip-rap (5-6 inch diameter) can be "placed"on the OSCAR for protection from de r or elk traffic. These larger sized aggregates must be placed, not dropped, o the OSCAR to prevent breakage of piping and other materials. • Wire mess can be instal ed over the sand to prevent erosion and allow for grass to grow.
