Engineering - Frequently Asked Questions

Development Projects

1. I am developing a new subdivision or other type development within the Snyderville Basin.  What is the process for connecting the development to the Public Wastewater System?
   
   The process for connecting developments to the Public Wastewater System is discussed in Section 202 of the Development Procedures, Design Standards and Construction Specifications document.  Please refer to the Standards and Specifications link for specific information.
   
   
2. I understand that a Line Extension Application and Agreement (LEA) must be submitted to the District to receive approval from the Board of Trustees to begin the planning and design of the wastewater system extension necessary to serve my development. When should I submit the LEA?
   
   LEA’s, along with the required development fees, should be submitted a minimum 2 weeks prior to a regularly scheduled Board of Trustees meeting in order to be placed on the agenda for the Board meeting.  The Developer and his Engineer should have met with the District Engineer and Development Coordinator prior to submittal of the LEA to discuss the development process.
   
   
3. What fees are required for extension of the wastewater system to serve a new development?
   
   There are two separate fees associated with extension of the wastewater system.  A $100 Application Fee must be submitted with the LEA and covers the District=s cost for processing the application. A Subdivision Engineering Fee in the amount of 6% of the estimated construction cost for the wastewater system improvements required to serve the development is also required. This fee covers the District=s time, effort and expense in reviewing designs, and providing construction inspections and general project coordination for those improvements.  An initial payment of $750 is required at the time LEA is submitted. Payment of the remainder of this fee is required prior to Plat Approval or Final Design Approval.  Assessment and payment of Impact Fees occurs at the time a building permit for a specific building is being requested.  See the Finance link for information regarding Impact Fees.

Private Lateral Connections

1. How do I schedule an inspection of a Private Lateral?
   
   Call (435)649-7993 and press 2 when you hear the recording.  You will need to speak directly to the Engineering Secretary to schedule an inspection appointment.  If you are unable to speak directly to the Engineering Secretary, please leave a message and she will return your call as soon as possible. 
   
   
2. How soon before an inspection do I need to call for an appointment?
   
   Please allow a minimum of 24 hours. The District will make every effort to complete inspections within 24 hours of the time an inspection is requested.  However, during peak inspection periods, additional time may be needed.
   
   
3. How far apart should cleanouts be placed?
   
   Clean outs are required within 5 feet of the foundation, and for each 100 feet of length (as measured from the inlet rim of the cleanout standpipe) or 135 degrees of bends from the connection to the public main line.
   
   
4. What type of cleanout cap is required?
   
   Clean out caps must consist of an iron bodied thread adapter with a threaded brass cap or cast iron blind cap.  The cap must be attached to the cleanout riser pipe with either a Fernco connector or a no-hub band (this is the only location outside the building where a no-hub band may be used on the private lateral).  Cleanout caps must match the diameter of the lateral.
   
   
5. Are cast iron wyes required on the cleanout?
   
   No.  Clean out wyes must be the same material as the lateral pipe. All cleanout wyes must be supported by a wet poured concrete saddle at least 3" thick for the length of the wye.
   
   
6. Can I lean the cleanout over to avoid having it surface in my driveway, porch, etc.?
   
   No. The cleanout standpipe must be vertical, and in line with the pipe being served. The plumber installing the interior plumbing should be made aware of this requirement and pre-plan the building stub out to avoid inconvenient conflicts.
   
   
7. What type of pipe joints are allowed?
   
   So long as there is no sewer and water conflict, plastic piping materials such as ASTM 3034 / SDR 35 PVC pipe may be either gasketed bell and spigot joints or glued joints. Glued joints must use fittings specifically designed to be glued.  Both glue and purple primer must be visible on the joint. Combination primer/glue compounds must still use a separate purple primer.  Glued joints between different types of plastic pipe are not allowed. Glued joints are required within 10 feet of all sewer line and water line crossings, wherever there is less than 10 feet of separation between sewer lines and water lines, or where the sewer line is above the water line.
   
   
8. What type of bedding material is required?
   
   Unless specific special bedding requirements are called for on the sewer location request, laterals are to be bedded in 3/4" minus gravel.  (Pea gravel is also acceptable.)
   
   
9. What is the minimum cover required over private laterals? 
   
   Minimum cover over gravity lines is 4 feet.
   Minimum cover over pressure lines is 5 feet.
   Building stub outs must be a minimum of 4 1/2 feet or 5 1/2  feet, respectively, below the top of foundation to provide adequate ground cover.) 
   
   
10. What testing is required on the private lateral line?  
    
    All piping and joints must be tested for leakage.  The District allows testing of gravity lines with either compressed air, or water.  All lines are to be under test at the time of the inspection appointment. All adjustments for temperature, seating of gaskets, trapped air, floor drains, etc. must be made prior to inspection appointment.   Please refer to the Standards and Specifications link for specific testing details.
    
    
11. The plat of my subdivision indicates that my lot is an EP or LPSS lot. What does that mean?  
    
    EP means your lot is an Ejector Pump lot. Your lot is located lower in elevation that the public gravity sewer main and you will need to install a private sewer ejector pump to lift your wastewater up to the public main.
    
     LPSS stands for Low Pressure Sewer System. Sewer service to this area is provided by a low pressure sewer system which requires a private low pressure pump to discharge your wastewater into the public system. Your private low pressure pump must be compatible with the LPSS in order to function properly. Currently the only approved LPSS system in the District is the e-ONE system.
