Design flow definition

Design flow means the average annual flow or average daily flow specified in an approved facilities plan or approved plans and specifications, the flow specified in a WPDES permit, or the flow required to meet performance standards.
Design flow means the anticipated daily discharge from a building as determined in accordance with Sections IV and VIII F of the Technical Standards.
Design flow means the maximum volume of sewage a residence, structure, or other facility is estimated to generate in a twenty-four-hour period. It incorporates both an operating capacity and a surge capacity for the system during periodic heavy use events. The sizing and design of the on-site sewage system components are based on the design flow.

Examples of Design flow in a sentence

  • Design flow discharges for the LFC, including updates on the hydrology of frequent events.

  • Design flow shall consider future demand, including all potential developable land within the area of extension.

  • Design flow shall be the greater of the required fire flow plus peak domestic demand or the target for the level of service standards.

  • The calculations for dilution used for chronic WET testing are as follows: Critical dilution (CD) = (Qd/(Qd + Qb)) X 100Qd = Design flow = 16 MGD = 24.72 cfs 7Q10 = 819 cfsQb = Background flow = (0.25) X 7Q10 = 204.75 cfs CD = (24.72) / (24.72 + 204.75) X 100 = 11% Toxicity tests shall be performed in accordance with protocols described in "Short-term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Freshwater Organisms", EPA/600/4-91/002, July 1994.

  • Design flow depths at the road centerline must not exceed 6 inches during the 100-year, 24-hour design storm (planned land use).


More Definitions of Design flow

Design flow means the daily flow rate a facility is designed to accommodate on a sustained basis while satisfying all Aquifer Protection Permit discharge limitations and treatment and operational requirements. The design flow either incorporates or is used with appropriate peaking and safety factors to ensure sustained, reliable operation.
Design flow means the maximum volume of sewage a resi- dence, structure, or other facility is estimated to generate in a twenty-four-hour period. It incorporates both an operating capacity and a surge capacity for the LOSS during periodic heavy use events.
Design flow means the maximum volume of wastewater estimated to be generated by a dwelling or non-dwelling facility in a twenty-four-hour period. It includes both a typical operating capacity and a surge capacity for the system during periodic heavy use events. The sizing and design of the onsite wastewater treatment system components are based on the design flow.
Design flow means the maximum volume of sewage a residence, structure, or other facility is estimated to generate in a twenty-four-hour period. It incorporates both an operating capacity and a surge capacity for the OSS during periodic heavy use events. The sizing and design of the OSS components are based on the design flow.
Design flow means the flow rate for which an on-site liquid waste system must be designed in order to assure acceptable system performance, assuming the use of conventional plumbing fixtures;
Design flow means the flows, set by section 1-504 of these Rules and Section 2.2 of the Vermont Water Supply Rules, that establish the size of the potable water supply and wastewater system serving a lot, building or structure, or campground.
