General .1 Scope of Work This specification covers the work necessary to install a washout water recovery system for the Caldwell Ready Mix, Inc. concrete batch mixing plant. 1.2 System Description This system is designed to treat 100% of all wastewater generated in cleaning out concrete mixing drums and in washing the exterior concrete mixing trucks. Additionally, the system reclaims sand and gravel from the washout effluent. The sand and gravel is separated by mechanical screening into individual stockpiles. The wastewater originates from cleaning the batch truck mixing drums which are manually washed out and the contents expelled into a hopper that feeds mechanical screw screening conveyors. The screening augers are continually washed to eliminate cement and flyash residue from the saved materials, which drain off into sedimentation basins. The hopper is located on a drainage slab so that the water from extericr washing of the mixer trucks is contained and allowed to drain into the sedimentation (clarification) basins. The drainage effluent from the drum washout, the screening process and from the exterior truck washing all drain in common to clarification basins noted as B1, B2, and B3 on the drawings. The water from the last basin is pumped back to the start of the system for reuse and recycling. A portion of this reclaimed water is used in the batch mixing of fresh concrete to be delivered off site. This loss of reclaimed water requires the addition of daily make-up water to offset the loss. Settled solids will be removed from B1 and B2 by front end leader and manually from B3 and will be either recycled or handled as solid waste. No surface drainage water will be allowed to enter the system. It will be diverted around the reclaim facility to exit by the natural water shed. 1.3 Project Description The project shall consist of removing the existing sedimentation lagoon and stock pile, site grading, construction of slabs and sedimentation basins, installation of mechanical equipment, and site drainage grading for diversion of surface run-off. Page 1 of 6 1.4 Regulatory Requirements All work, materials, supplies, and equipment shall be in compliance with all local, state and applicable federal codes and regulations. No work shall be commenced until such time that all permits and approvals have been obtained. 1.5 Erosion Control An Erosion/Sedimentation Control Plan will not be required for the project. However, prior to construction, proper protection of the nearby stream shall be obtained by installing protective measures to prevent excessive siltation from impacting the stream. These protection measures will be maintained throughout the construction process. Any temporary sedimentation basins constructed during the construction phase shall be maintained in a manner to prevent overflowing or runoff into the stream. Protection features will be removed at the completion of construction as necessary by removal and disposal of siltatious materials. All de-nuded areas shall be properly grassed and mulched as soon as practicable. Part II. Products 2.1 Concrete All concrete shall have a minimum of 3,000 psi compressive strength and a slump of 5 inches or less. 2.2 Equipment All equipment, pumps, conveyors, hoppers, etc. shall be consistant to the requirements of the project. The mechanical equipment shall be as manufactured by J&H Equipment Inc., Roswell, Georgia or equal. All mechanical equipment including pumps, shall be provided by the Owner and installed by the contractors. 2.3.Reinforcing Steel All reinforcing steel shall be intermediate grade billet steel, deformed bar stock, clean and free of all rust and corrosion. 2.4 Backfill Materials Exterior walls of the recycle facility clean, well compacted soil and/or with as manufactured by the on site concrete Page 2 of 6 shall be backfilled with flowable backfill material batch plant. 0 • Part III.
