33、on bells, air bells, inlet castings, and similar equipment shall be cast iron, polyvinyl chloride (PVC) or polyethylene. Siphon bells shall be provided with suitable connections for the air-control piping and the sniff pipe shall be mounted over the _ mm inch diameter feed pipe. Each siphon shall be

34、 capable of discharging at a maximum rate of flow of _ L/second gpm while operating under a drawing depth of _ mm inches, and under the head conditions as indicated on the drawings. The average rate of inflow shall be _ L/second gpm and the minimum 4-hour average rate shall be _ L/second gpm. Each s

35、iphon shall be provided with a seal trap in the discharge pipe of such depth that an effective seal against blowing shall be maintained at all times. Each siphon shall discharge into an airtight piping system having a discharge point about the lowest point in the connecting pipe to form an effective
