Engineering Public Projects: Overview

Investing in Our Infrastructure

Johnson County is a community that is thriving both socially and economically. This continued prosperity is strengthened by having reliable and sustainable wastewater networks with the capacity to support the community. Johnson County Wastewater's Engineering Group manages sewer design and construction projects throughout the County. These improvements are being built so that we can continue to provide you, our customers, with reliable sanitary sewer service.

Living With Construction

Johnson County Wastewater does all it can to minimize the impact of sanitary sewer construction on people who live and work in the project areas. Sometimes this work goes unnoticed because it often takes place underground. But occasionally work must be done in streets or alleys near homes or businesses. We take care to reduce noise, dust, traffic, and any other potential construction nuisance to a minimum. We also meet with and mail updates to impacted neighbors before and during construction to get their input and provide them with progress reports.

Sewer Expansion

The traditional method for enlarging Johnson County Wastewater’s sewer service area is to petition to add the described land to the Consolidated Main Sewer District (CMSD).  The enlargement process is described in the link below. Publically-financed main sewers do not serve every parcel of land within a watershed, but provide the backbone of the sewer system.  Branch lines which extend from these publically-financed main sewers are privately financed by the property owners.

Grease Management: All About Fats, Oils, and Grease

My Government Online (MGO) Electronic Application, Plan Review and Inspection software launched for JCW on MAY 1, 2017.  Please visit www.mygovernmentonline.org and create your customer portal account.

What is FOG?

FOG is a combination of fats, oils, and grease. FOG includes cooking oil, animal fat and lard, grease, butter, tallow, shortening, and margarine which are all used in food processing and in the preparation of food. Kitchen wastes, along with water that has been used to wash kitchen equipment and floors, contain FOG.

Protecting public health and safety is a prime responsibility of Johnson County Wastewater (JCW). Sewer blockages and subsequent sewage spills pose a threat to public health and safety which can be prevented with proper grease management. When FOG or food and wastewater containing FOG are poured down the drain, it cools and solidifies on the walls of the sewer pipes, restricting or clogging the wastewater flow. This can result in a wastewater backup into homes and businesses or discharge to the environment. The most effective way to minimize FOG accumulation in sewers is to prevent the introduction of FOG into the sanitary sewer system in the first place. To realize this goal, JCW has developed the Grease Management Program to regulate food service facilities.

Each facility will receive an Operating Permit with Commercial Permit issuance.  The Operating Permits for all grease interceptors and facilities operating under low grease discharge waivers expire on April 15th each year and must be renewed annually.  Facilities currently permitted by Johnson County Wastewater will receive a notice prior to permit expiration with renewal materials and instructions. 

Permits are valid only for the year in which they are issued.  There are no provisions for the proration of a license or refunding the licensing fees.

Grease Interceptor Pumping Variances

Interceptor pumping and cleaning is required at a minimum of once every 90 days for most establishments. A variance may be considered if you believe your interceptor requires less frequent pumping by completing the following steps. 

Once the application and fees have been submitted, the operator must have the interceptor pumped and cleaned while Johnson County Wastewater is present to begin the variance process.  Please call the Johnson County Wastewater Environmental Compliance Managers at 913-715-8520 to schedule an inspection.

Grease Management: Best Management Practices

Prevention is Best

Protecting public health and safety is a primary responsibility of Johnson County Wastewater. Sewer blockages and subsequent sewage spills pose a threat to public health and safety that can be prevented when food service facilities follow the Best Management Practices (BMPs) presented here.

Johnson County Wastewater has determined that the most effective way to minimize Fats, Oils, and Grease (FOG) accumulation in sewers is to prevent the introduction of FOG into the sanitary sewer system in the first place. Follow these tips to help control and minimize the introduction of FOG into sanitary sewers:

  • Post "No Grease" signs above sinks and on the front of dishwashers and/or floor sinks.
  • Wipe pots, pans, dishware, and work areas with paper towels prior to washing, and dispose the paper towels in the trash.
  • Dispose food waste directly into the trash. Garbage grinders/disposals are prohibited.
  • Use absorbents or other materials, like paper towels, to pick up spills before mopping the floor, then dispose of the towels in the trash.
  • Collect cooking oil waste and store in drums or barrels for recycling.
  • Keep grease emulsifying agents out of the sink and drain.

Grease Management: Interceptor Design, Inspection, and Operation Requirements

My Government Online (MGO) Electronic Application, Plan Review and Inspection software launches for JCW on MAY 1, 2017.  Please see our article homepage and create your customer portal account.

The following are requirements for new grease interceptors installed at food service facilities:

Design

  1. The grease interceptor must be of sufficient size to provide a 30 minute detention of the peak wastewater flow. The minimum size for a grease interceptor is 1,000 gallons. The maximum size is 2,000 gallons. The interceptor location must allow for pumping and inspection access. Indoor grease interceptors or grease traps are not permitted in new facilities.
  2. An engineer shall submit grease interceptor sizing calculations on plans and indicate sizing method used (see ​​Interceptor Sizing information below).
  3. The vent line from the sample port riser on the interceptor outlet must be connected to the building waste vent piping.
  4. Grease Waste Fixtures:
    • Garbage disposals or grinders are prohibited in new food service facilities.
    • The following plumbing fixtures (if applicable) MUST NOT be connected to a grease interceptor:
      • Handwashing sinks
      • Drains receiving condensate only
      • Bar sinks not receiving significant quantities of grease
    • The following plumbing fixtures (if applicable) MUST be connected to a grease interceptor:
      • Low temperature chemical (e.g., chlorine) sanitizing dishwasher
      • High temperature (greater than or equal to 180°F) sanitizing dishwashers which must have a cold water solenoid-operated valve or similar device that mixes cold water with the discharged hot water from the machine
      • Three (3) compartment sinks
      • Mop sinks
      • Floor drains in kitchen areas
      • Wok drains

​​Interceptor Sizing

A grease interceptor must provide a 30 minute peak hydraulic detention time as determined by the plumbing fixtures or piping connected to the interceptor. The following table is used to size grease interceptors in the Johnson County Wastewater sanitary sewer service area:

Chart

Method 1

All kitchen drains must be plumbed to the grease interceptor. When using the table above, only use sinks and dish machines in the calculation. Floor drains and mop sinks do not produce a sufficient quantity of water to be added to the calculation, but must be plumbed to the interceptor.

For dish machines, multiply the result by a factor of 0.3 to compensate for the time that the machine is not discharging wastewater.

The interceptor is sized using the drainage gallons per minute multiplied by a 30 minute detention time.

Example: For a two (2) inch drain discharging to a grease interceptor from a three (3) compartment sink and a 2.5 inch drain from a dish machine discharging to the grease interceptor, the calculation is as follows:

22.5 gpm x 30 minute detention time = 675 gallons for the three (3) compartment sink

30 gpm x 30 minute detention time = 900 gallons x 0.3 factor = 300 gallons for the dish machine

675 gallons + 300 gallons = 975 gallons for the interceptor. Round up to 1,000 gallons

Method 2

The pipe diameter after the last grease waste fixture is used to determine the size of the grease interceptor. Pipe shall be installed at one (1) percent slope maximum. Pipe slope shall be indicated on interior plumbing drawings.

Example: For a 4 inch line downstream from the three (3) compartment sink and the dish machine discharging to the grease interceptor, the calculation is as follows:

45 gpm x 30 minute detention time = 1,350 gallons for the interceptor. Round up to 1,500 gallons.

The minimum size for a grease interceptor is 1,000 gallons and 2,000 gallons is the maximum size.

If a larger capacity is needed, grease interceptors shall be connected in series and must be approved by Johnson County Wastewater.

Permit Execution Requirements

Johnson County Wastewater permits shall be issued to the Property Owner. The Property Owner may sign the permit or may authorize another individual to pick up and sign the permit on the Owner’s behalf. The Owner must provide the company name(s) and individual’s name(s) for permitting. The individual authorized to execute the permit is responsible for providing a copy of the permit and all associated documentation to the Owner.
 
By authorizing another individual to execute the permit on the Owner’s behalf, the Owner acknowledges the following understanding in addition to all conditions of the permit:
The Owner understands and acknowledges that connection fees assessed pursuant to the Johnson County Wastewater Sewer Use Code (the Code); are assigned based on the water meter size and use of the building as it is designed at permit issuance and when a new meter or existing meter size is changed by the water utility or if the use, expansion or modification to the building occurs for tenant finish, the plans must be submitted to Johnson County Wastewater for review. Based upon that review, a Modified Use Permit may be required that could result in the assessment of additional connection fees.  Upon completion of the review process, the Owner remains responsible for the payment of any additional connection fees associated with the Modified Use Permit and satisfaction of any conditions contained in the permit.
 
The Owner further understands and acknowledges that if a Modified Use Permit is not obtained and additional connection fees paid prior to the issuance of a City or County Occupancy Permit, the additional permit fees are considered delinquent and shall be assessed and collected (plus interest) in the manner provided by the Code and applicable Kansas law.

Permitting: Residential

My Government Online (MGO) Electronic Application, Plan Review and Inspection software launches for JCW on MAY 1, 2017.  Please see our article homepage and create your customer portal account.

*Effective June 1, 2015* 

JCW will inspect to ensure all ground and storm water sumps are located a minimum of 3 feet away from floor drains.  Floor drains shall not be provided for the purpose of accepting flow from a sump pit.  JCW inspection of the completed sump and floor drain installation is required for final approval of the connection.

Effective Jan. 1, 2014, sewer connection fees are no longer based on Equivalent Dwelling Units (EDUs) calculated by square footage and business activity type. Instead, the fees are based on the water meter size for each building or space as issued by the water utility (e.g. WaterOne, City of Olathe, BPU, et al).

Why the change? This change in methodology was approved on March 15, 2012, by the Johnson County Board of Commissioners and makes Johnson County Wastewater's policy consistent with industry best practices and standards.

How does this change affect me? The policy affects information required for residential permit issuance and the order of submissions during the commercial permit application process. In addition, for commercial permit projects, the modified use fee portion of permits associated with tenant finish or building addition projects no longer applies.

The Johnson County Wastewater connection fee schedule does apply and customers are required to obtain a Sewer Connection Permit for all new water meters or when a water meter size increases. Fees are due to Johnson County Wastewater at the time the meter or meter size change permit is issued by the water utility. Fees for meter size increases are calculated as the difference in fee between the existing meter and the new meter. The $200 Johnson County Wastewater permit fee, the $400 commercial review fee, additional special inspection fees, and/or grease permit fees continue to be charged for permits as applicable.

Effective Jan. 1, 2014, sewer connection fees are no longer be based on Equivalent Dwelling Units (EDUs) calculated by square footage and business activity type. Instead, the fees are based on the water meter size for each building or space as issued by the water utility (e.g. WaterOne, City of Olathe, BPU, et al).

Residential Sewer Connection Permit

To acquire a building permit for a single-family residential building or for a multi-unit residential building, where each unit in the building has a separate connection point provided on the sanitary sewer main, a Sanitary Sewer Connection Permit must first be issued to the property owner from Johnson County Wastewater. Existing residential buildings connecting to the sanitary sewer from a septic system or holding tank must also obtain a Sanitary Sewer Connection Permit.

The following information is required for issuance of a Residential Sanitary Sewer Connection Permit:

  • Correct building address
  • Correct legal description of property including: lot number, subdivision name, and plat number or, if the property is not platted, the full boundary description
  • Name, address, phone number, and email address of the property owner
  • Name, address, phone number, and email address of the builder
  • Names, addresses, phone numbers, and email addresses of the interior and exterior plumbers
  • Effective Jan. 1, 2014, when applying for a sewer permit, Johnson County Wastewater needs to know the size of the water meter as issued by the water utility.
  • Copy of the plot plan showing the entire lot, the building, and the proposed routing of the building service line under any of the following conditions as applicable: septic to sewer, more than one building on the lot connecting to sanitary sewer, large lots that require more than 100 feet of service line on the lot to serve the building, or for lots that are to either be split, combined with another lot, or platted

Permit Execution Requirements

Johnson County Wastewater permits shall be issued to the Property Owner. The Property Owner may sign the permit or may authorize another individual to pick up and sign the permit on the Owner’s behalf. The Owner must provide the company name(s) and individual’s name(s) for permitting. The individual authorized to execute the permit is responsible for providing a copy of the permit and all associated documentation to the Owner.
 
By authorizing another individual to execute the permit on the Owner’s behalf, the Owner acknowledges the following understanding in addition to all conditions of the permit:
The Owner understands and acknowledges that connection fees assessed pursuant to the Johnson County Wastewater Sewer Use Code (the Code); are assigned based on the water meter size and use of the building as it is designed at permit issuance and when a new meter or existing meter size is changed by the water utility or if the use, expansion or modification to the building occurs for tenant finish, the plans must be submitted to Johnson County Wastewater for review. Based upon that review, a Modified Use Permit may be required that could result in the assessment of additional connection fees.  Upon completion of the review process, the Owner remains responsible for the payment of any additional connection fees associated with the Modified Use Permit and satisfaction of any conditions contained in the permit.
 
The Owner further understands and acknowledges that if a Modified Use Permit is not obtained and additional connection fees paid prior to the issuance of a City or County Occupancy Permit, the additional permit fees are considered delinquent and shall be assessed and collected (plus interest) in the manner provided by the Code and applicable Kansas law.

RESIDENTIAL – PUBLIC STREET RESTORATION PILOT PROGRAM

I. Introduction

Homeowners are responsible for the repair/replacement of their private service line from the home’s connection to the point of connection on the public sanitary sewer main. The service line sometimes runs under paved public streets in public street right-of-way. The cost for replacement of a private sanitary sewer service line serving a single family residential property can be substantial and including the cost of public street restoration can make the repair even more costly.

To mitigate public street restoration expense, the Johnson County Board of County Commissioners approved a pilot street restoration reimbursement program in March 2016 which allows reimbursement of up to $5,000 per single family residential property for restoration of the paved public street in the public street right-of-way. The program is administered by Johnson County Wastewater and is subject to the homeowner meeting specific application and qualification requirements. All private service line repairs must meet Johnson County Wastewater inspection standards and all street repairs must meet City permit and inspection standards.

Homeowners would be informed by a plumbing company or by Johnson County Wastewater if the issue is with their private street line and whether or not it will require street restoration and therefore, would qualify for reimbursement.

The reimbursement may be subject to federal or state income tax and participants are advised to consult with their tax advisers.

II. Applicant Requirements for Repair with Public Street Restoration Permit

  1. Applicant (may be Owner or someone authorized to represent the Owner(s)) must complete the Johnson County Wastewater Single Family Residential Repair with Public Street Restoration Online Application.
  2. Submit the application.
  3. 1. Johnson County Wastewater will contact the Owner or Owner’s representative once the application is received.

NOTE: This Pilot Program does not apply to restoration of Private streets.

III. Eligibility

Applicants must meet the following requirements in order to be eligible for reimbursement consideration:

  1. The property must be connected to and served by a sanitary sewer district that is operated by and under the jurisdiction of Johnson County Wastewater;
  2. Property is currently and/or regularly occupied exclusively for single-family residential uses;
  3. The building service line for the property runs under a paved public street;
  4. Confirmation from Johnson County Wastewater that CIPP (Cured-In-Place-Pipe) Lining or Pipe Bursting cannot be utilized;
  5. First come, first served.  Reimbursement is dependent upon funds remaining in the Street Restoration Fund for reimbursement.  Once the reserved fund ($500,000) is depleted, no additional reimbursements will be available.

IV. Applicant Permit Issuance Requirements

  1. None. Johnson County Wastewater does not require the issuance of a permit for this program but confirmation that the repairs will include restoration of the paved public street is required prior to reimbursement.

V. Property Owner Reimbursement Requirement

To qualify for reimbursement of street restoration repairs, the following documentation must be provided to Johnson County Wastewater:

  1. Signed Street Restoration Agreement.
    The Street Restoration Agreement (provided by Johnson County Wastewater) must be signed by all record Owners of the subject property and returned to Johnson County Wastewater prior to reimbursement of street repair costs. The addresses of all record Owners must be included on the Agreement.
  2. An executed W9 form (provided by Johnson County Wastewater) must be received from each Owner.
  3. A Johnson County Wastewater approved building service line repair inspection form.
  4. A City (or other applicable public entity if not a City) approved street restoration inspection form.
  5. A detailed statement (itemized estimate or paid invoice) or copy of the contract between the Owner(s) and the plumber or contractor that was hired to perform the work indicating the nature and extent of building service line repairs to be completed, the anticipated cost of such building service line repairs and the anticipated cost of restoring the public street.
  6. Johnson County Wastewater may request additional information from the property owner as may reasonably be necessary to review and determine if reimbursement of street restoration costs is qualified for and should be approved under the Pilot Program.
