20 Design should be such that precipitation rate is less than the infiltration rate, to limit runoff. Provide design application rates per zone. In general, design should be at rates less than 1/2 inch per hour AND at less than 15 gpm. Provide a chart with run times and application rates per zone to ensure rates do not exceed ½ per hour. Example Zone Run time/minutes Approx. Rate <.5 /hr Required rain sensors must be shown and must restrict irrigation from happening during rainfall events Show irrigation zones labeled by number. Include square footage for each zone. Spray and rotor irrigation heads cannot be used within the same zone. Plants with different irrigation requirements (such as grass and shrubs) be on separate zones. The controller should have multiple programs so that different irrigation schedules can easily be utilized. All heads and drip emitters should have pressure regulation; it can be at the point of connection to the water supply, at each zone valve or located in each head/emitter. Guidelines for pressure regulation at the head/emitters: Spray Heads - 20 to 35 psi, Gear Rotors - 60 psi or less, Impact Rotors - 60 psi or less, Drip emitters - 40 psi or less. Buffers from streams and surface waters per state standards Recommended maintenance schedule Place note on plan that states As-builts certification will be required prior to final certificate of occupancy and approval. Verify lot is covered in approved area with a soils report Verify by looking at training log that designer has completed TOHS Reclaimed Training Verify if residential designed by PE, LA, or CID, if non-residential must be designed by PE Reclaimed Irrigation Plan Review Checklist Page 2 of

29 Reclaimed Water Designer, Contractor and User Training Rev. February 2011 This presentation provides required training for all users, designers, and contractors on the requirements for reclaimed water 1

30 What Is Reclaimed Water? Highly treated wastewater that has gone through advanced treatment processes that remove solids, organics, and pathogens Has been filtered and disinfected with UV and chlorinated Is colorless and odorless Water that meets the State s health and safety standards for beneficial reuse Regularly tested for compliance Also called Reuse Water 2

31 Benefits of Reclaimed Water Reduces community s risk to droughts Defers the need for expanding expensive potable water supply capacity Reduces the amount of nutrients (Nitrogen and Phosphorus) discharged into the creek at the WRF Expands total supply of water to the community that increases as the community grows 3

32 Communities Using Reclaimed Water Used by decades in other areas Florida and California Use in NC relatively new Cary, Sanford, Johnston County, OWASA, Raleigh, Wilson, and others Track record of safe use for a variety of purposes 4

33 Who must be Trained? Designers of reclaimed water systems Installers of reclaimed water systems Customers receiving reclaimed water Customers hauling reclaimed water Customers utilizing reclaimed water Training is required prior to performing any duties associated with distribution of reclaimed water 5

34 Training Outline More about Reclaimed Water What Are the Benefits of Reclaimed Water? What Can Reclaimed Water Be Used For? What Can Reclaimed Water NOT Be Used For? Application and Review Procedures What Are Your Responsibilities as a reclaimed designer, contractor, customer? Spill Prevention / Response 6

35 Water Quality Meeting Water Quality parameters is the responsibility of the Town s Department of Public Utilities. Records of Water Quality Data as required by the State for parameters such as Turbidity, TSS, NH 3, BOD 5, and fecal coliform are collected and maintained at the Town s Utley Creek Water Reclamation Facility (WRF). Online turbidity and chlorine residual instruments provide 24/7 monitoring of the reclaimed water leaving the WRF. If the reclaimed water is not in compliance with State requirements for distribution, delivery of reclaimed water will cease until back in compliance with required standards. 7

36 Water Quality Constituent Reclaimed Water Quality Parameters Daily Maximum Limit Monthly Average Limit Continuous Monitoring Limit Recent Performance TSS, mg/l < 1 Fecal Coliform 25/100 ml 14/100 ml - < 6 CBOD5, mg/l <2 NH3, mg/l < 0.5 Turbidity, NTU <2 These permit limits have been established by statutory regulation as that which will provide for protection of public health and environment. TOHS also regularly tests for many other parameters, contact the Public Utilities Department for more information. 8

61 Spill Prevention Users shall transport and apply the reclaimed water in such a manner to prevent spillage. Irrigation water shall be applied in such a manner as to not create any runoff which would flow into adjacent areas not approved for reclaimed water application. If runoff or ponding begins to occur during the application of reclaimed water and is confined to the approved area: Application shall be ceased immediately until the cause of the ponding or runoff is remedied Truck driver providing the water shall remain at the site of irrigation until all water infiltrates into the soil Truck driver shall provide signage to notify the public of the presence of reclaimed water 33

62 Spill Response If ponding or runoff leaves the application site or occurs in a location which would not otherwise be deemed acceptable for reclaimed water application, the following steps shall be followed. Application shall be stopped immediately upon observation of a spill. Truck driver shall notify the Town s emergency contacts listed on the Reclaimed Water Information Sheet to report the spill. If ponding occurs, then appropriate signage shall be installed to warn the public of the presence of reuse water until the spill is remedied. 34

63 Spill Response If the spill occurs on an impermeable surface which would allow the water to flow to a nearby storm drainage device such as a catch basin: the storm drainage device shall be blocked to prevent flow from entering the device until the reclaimed water is removed or evaporates. The Hauler shall remain at the site until the spill is remedied or Town personnel arrive in response to the spill notification. Town personnel will determine the best remedy to the spill. If runoff occurs which allows reclaimed water to enter any storm drainage system or nearby surface water body, this shall be reported to the North Carolina Department of Natural Resources in accordance with the permits. 35

64 Enforcement Holly Springs has enforcement authority over users of water, sewer, and reclaimed water Violations (training, permit, regulations) Retake training (required) Repeated violations will result in revocation between 6 months and permanent revocation, to be determined by the Town Staff on a case by case basis 36
