Air coil in sand filter to be geoflow WF16-4-24 150 LF placed 6" above bottom of sand. Construction of Sand Filter The sand filter construction is to follow procedures as outlined below, as applicable to this design. Pea gravel and filter sand are to be hand leveled to proper depth (tolerance within 0.05 feet) in filter, taking care not to allow mud or fine soil material into the filter or gravel layer. This would include any soil material picked up by excavation machinery buckets while loading specified material. The Contractor should estimate filter material volumes such that allowance is made for wastage of material in contact with the ground at site. The area over the sand filter to be finish graded with a minimum of 2 feet of cover and to prevent ponding of surface water run off. Side slopes shall not exceed 3:1. The Engineer will reject any sand or pea gravel that does not meet specifications or is contaminated in transit or while handling. If such material is placed in the filter, all soil material may be required to be removed and replaced with new material. CONTRACTOR/ INSTALLER
