Water Design Criteria

Design Criteria

The requirements below are critical items required by Tennessee Department of Environment and Conservation (TDEC) and the Rules, Regulations, Rates, and Policies of LCUB’s Water Department. The engineer must ensure all requirements are met. LCUB strongly recommends a pre-design conference to review the development layout, including topography and sewer features, to ensure a successful project.

TDEC Requirements for General Plans of Water Distribution Systems

  1. All plans must be approximately 24″ x 36″ minimum.
  2. Maximum scale for plans and profiles: 50 feet/inch; Maximum vertical scale: 10 feet/inch.
  3. Must include the name of water system and county in which it is located.
  4. The engineer’s name, address, and telephone number must appear on Page 1.
  5. Plans must be stamped and signed by a licensed engineer.
  6. Include a vicinity or location map showing the location of the project if a complete system map is not included.
  7. A key map that shows the location of detailed drawings is required when the project is comprehensive.
  8. Maps must clearly show the location, size, and material of all existing and newly planned water lines and appurtenances related to the project.
  9. Stream crossings, including elevations of the stream bed and the normal / extreme high and low water levels (if available) must be included.
  10. Maps must clearly show how the location of proposed water lines coincides with nearby roads, bridges, and other identifiable objects.
  11. All valves, fire hydrants, tees, reducers, enlargers, bends, and other appurtenances must be visible on maps.
  12. A hydraulic profile (or data and computations showing hydraulics or proposed additions) must be included. (NOTE: LCUB’s minimum standards are 750 gpm fire flow with 30 PSI residual pressure. This exceeds the State of Tennessee minimums. LCUB also requires the lowest and highest static and residual pressure to be calculated and shown on the plans.)
  13. Plans must be clear and legible.

LCUB Requirements

LCUB requires the following items, in addition to the list above:

 

  1. The first page of the plans must include the following:
    1. Project layout map with project name and design date.
    2. Developer’s name, address, and phone number.
    3. Property owner’s name, address, and phone number.
    4. Servicing utility’s name, address, and phone number (LCUB, 7698 Creekwood Park Blvd., Lenoir City 37772, 1-844-687-5282).
  1. The items below must be included in the plans:
    1. Rights of way and easements needed for the water that falls inside / outside of the property.
    2. Lot lines and locations shown on all plan views, including lot numbers.
    3. Street names, edge of pavement locations, and the appropriate rights of way.
    4. Locations of proposed service connections. Taps must be spaced to avoid conflict with sanitary sewer laterals.
    5. A 100 foot stationing of water lines and stationing of all appurtenances on plan and included profile views.
    6. Sufficient details shown to allow for material take off and location of lines in the field by a third party.
    7. Plan / profile sheets must be drawn for water lines 12 inches in diameter and larger. Existing lines must be field located whenever reasonable. The source of the utility locations must be noted on the plans.
    8. The relevant elevations of all pipe lines and conflicting structures at utility crossings (this includes a short profile view of all utility crossings of the water line where new utility lines are being constructed).
    9. When included, profiles must be on the same sheet as the plan and oriented in the same direction (they can also be included as inserts on a plan sheet if appropriate).
    10. Project name, date, scale, north arrow, and sheet numbers on all pages.
    11. Inclusion of LCUB detail sheets.
    12. Revisions tabulated on resubmissions.
    13. Include the radius of all turns where joint deflection is to be used to curve the water line. For 8 inch pipes, the maximum deflection per joint is 5 degrees. For curves tighter than this, please include the appropriate bends as part of the plans.

  2. The water distribution system shall be a minimum of 6 inch C-900 or ductile iron pipe (no exceptions). Upon review of the plans, LCUB reserves the right to require the water distribution system to be 8 inch C-900 or ductile iron pipe in lieu of 6 inch.
  3. The developer (owner) and / or contractor must install 3-way valve clusters at all roadway intersections.
  4. The developer (owner) and / or contractor is responsible for any existing water distribution improvements required to provide adequate water pressure and fire flow to the new development as well as maintain the existing distribution pressures.
  5. The developer (owner) and / or contractor must install all water taps, service lines, meter yolks, and casings per LCUB standard specifications for the new development.
  6. The developer (owner) and / or contractor must install all fire hydrants (not to exceed 500 feet) and appurtenances per LCUB standard specifications for new development.
