Title
SUBMISSION AND ACKNOWLEDGEMENT OF RECEIPT OF OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY CONSTRUCTION PERMIT SLR000014190515 FOR THE COMPOST FACILITY RE-USE PUMP STATION PROJECT LOCATED ADJACENT TO THE WATER RECLAMATION FACILITY.
Body
BACKGROUND: The Norman Utilities Authority (NUA) opened the Composting Facility at its current site in September 2009. Yard waste including grass, leaves, shrubs, and small tree limbs are accepted at the composting facility. Yard waste is ground into mulch with a tub grinder, mixed in the correct proportions to aid decomposition and laid out in long rows called windrows. The facility includes a looped irrigation water system to supply potable water for proper moisture control and curing of the compost. Initially, the windrows are about six feet high and sixteen feet wide, are kept moist with the aid of spray irrigation and mixed by turning about three times each week. The heat generated by the decomposition process raises the internal windrow temperature to approximately 130 degrees Fahrenheit. The composting process is complete in 90 to 120 days and the volume of mulch is reduced about 50% as the mulch decomposes. Cured compost is then released to our citizens and other users.
This project will provide for effluent reuse at Yard Waste Composting Facility located adjacent to and southwest of the Water Reclamation Facility (WRF)located south of Highway 9 off Jenkins Avenue. Reuse of treated wastewater effluent can reduce water demand and may help delay the need for expensive water supply projects. A non-potable water system allowing reuse of treated effluent on the grounds of the WRF is in place. Disinfected wastewater effluent may also be used for offsite irrigation purposes such as at the Compost Facility, if permitted by the ODEQ. This project will install a pump station downstream of the WRF Disinfection Facility to deliver treated and disinfected effluent the Compost Facility for irrigation purposes.
The WRF operates ...
