Water System Extensions Water system extensions shall be designed to provide for a domestic supply of at least 250 gallons per capita per day delivered at a minimum pressure of 42 pounds per square inch. The 250 gallon rate of supply shall not be required if, in the opinion of the City's Engineer, the proper point of connection to the existing system for the extension is not capable of supplying such a volume. How- ever, the extension should be designed to convey the 250 gallon rate should the supply point be subsequently improved. If the 42 pounds minimum pressure cannot be provided by existing system pressure or because of the elevation of the tract to be developed, a booster pump shall be included which will provide that minimum pressure. B. All Supply and Distribution Mains All supply and distribution mains installed within a subdivision must extend to the borders of the subdivision as required for future extensions of the system, regardless of whether or not such extensions are required for service within the subdivision. ~ ~ ~ · C. Fire Hydrants Fire hydrants shall be provided at locations such that all areas of single family development are located within a five hundred (5001) foot radius from a fire hydrant or all such hydrants will be placed so that hose line routes will not be more than eight hundred (8001) feet by public right-of-way. In areas other than single family development fire hydrants shall be on a three hundred (3001) foot radius. All such fire hydrants shall be served by a six (6") inch or larger supply or distribution main. O. Water Service Connections (This paragraph is deleted.) E. Two (2") Inch Mains (This paragraph is deleted.) F.

Sewerage System Extensions All subdivisions developed subsequent to this ordinance must be served by community sanitary sewerage collection, treatment and disposal systems approved by the City with exceptions granted only if all of the following conditions exist: (1) The subdivision in question is less than five parcels of land, (2) The existing community type collection, treatment and disposal system is not and cannot feasibly, in the opinion of the Cityls Engineer, be made available to the area of development and (3) Percolation tests run by an in- dependent testing laboratory are submitted to both the City and County Health Department with results showing that a septic tank and spreader field can be developed to provide adequate disposal of the sewage. Where septic tank instal- lations are permitted in lieu of a sanitary sewerage system, the plat must provide for dedicated alleys not less than 20 feet in width adjacent to all lots to facilitate the future installation of a sewerage system. Dedication of such alleys shall prohibit fencing or other obstructions that would interfere with the future installation of the sewers. · ~ ~ '~ B. Sewer Extensions · All sewer extensions shall be designed in accordance with the latest applicable rules and regulations as published by the Texas State Department of Health.

All sewers shall be designed with consideration for serving the full drainage area subject to collection by the sewer in question except as modified with the concurrence of the City·s Engineer because of the projected rate of development of the proposed extension. C. Population Equivalent In determining the population equivalent for design pur- poses, undeveloped areas shall be estimated at not less than 5 persons per acre. The contributing sewage flow shall be estimated on the basis of an average flow of 100 gallons per person per day plus infiltration of 1500 gallons per acre per day. The peaking factor for outfall sewers shall be determi ned as: 14 Peaking factor = 1 + 4 + \J P · P = population in thousands All sewers shall be designed with hydraulic slopes sufficient to give mean velocities, when flowing full or half full, of not less than two (2') feet per second nor more than five (5') feet per second based on Kutter's or Manning's formulas using an "n" value of 0.013. Sewers shall be designed in straight alignment wherever possible. Where horizontal curvature must be used, the smallest radius shall be one hundred (100·) feet. Manholes shall be constructed at all changes in grade, alignment or size of sewer and at all intersections of other sewers except service sewers and at the ends of all sewer lines that will be extended. Intersecting sewers shall enter the manholes at the crown line or top of the main sewer and the inverts of all manholes shall be formed concave to fit the connecting sewer pipe. D. Lateral and Sewer Mains All lateral and sewer mains installed within a sub- division must extend to the borders of the subdivision as required for future extensions of the collecting system regardless of whether or not such extensions are required for service within the subdivision. · ~ ~ ~ E.
