Plan Review and Permits


Minimum Design Standards

The Engineering and Permits Unit reviews and approves plans and specifications for drinking water projects for Kansas public water supply systems and issues permits for completed projects. Reviews are based on KDHE’s minimum design standards entitled “Policies, General Considerations, and Design Requirements for Public Water Supply Systems in Kansas, 2008 edition as well as other generally recognized drinking water design standards. KDHE’s minimum design standards are being made available in Adobe Acrobat format (.pdf).

KDHE’s minimum design standards were previously revised in 1995. Since 1995, additional regulations have been promulgated by USEPA, based in part on the 1996 Amendments to the Safe Drinking Water Act. KDHE decided to revise the 1995 bulletin to address these recent regulatory changes, to address recent technological developments, and to update obsolescent design criteria. The 2008 edition of KDHE’s minimum design standards was independently peer reviewed through the American Council of Engineering Companies of Kansas (ACEC). The State of Kansas appreciates the efforts of ACEC and its participating members.

Construction projects that will disturb one or more acres of land are required to secure, prior to the start of construction, authorization to discharge stormwater runoff under the construction stormwater general permit S-MCST-0110-1. Information regarding this authorization can be found on the Construction Stormwater Program web site.

Public Water Supply Permit Applications

The Engineering and Permits Unit issues permits for all public water supply systems. There are two types of public water supply permit applications. One is an Existing Public Water Supply System Permit Application. The other is a New Public Water Supply System Permit Application, Parts I and II which contains a technical, financial, and management capacity assessment in addition to the permit application. Permit applications for existing systems and new systems are available in Adobe Acrobat format (.pdf).

CT Helper

The purpose of the CT Helper is to assist public water supply system operators in developing a working knowledge of how to determine CT credit, log inactivation and total log removal and/or inactivation.  An example calculation is provided along with a blank CT calculation worksheet.  In addition, the log inactivation determined by completing the CT calculation worksheet can be utilized in the development of the disinfection profile and the determination of the benchmark for the disinfection practice employed by the treatment facility.

Point of Use/Point of Entry Policy

Point of Use (POU) or Point of Entry (POE) treatment may be an option for public water supply systems (PWSSs) where centralized treatment is not economically feasible.  This policy document is intended to assist PWSSs and their engineering consultants in evaluating POU/POE treatment as an alternative to more traditional centralized treatment.  As is the case in all facets of public water supply, the health and safety of the ultimate consumers of publicly supplied water is paramount, and thus is the focus of this document.

State Revolving Loan Fund

Public water supply systems may apply to the Kansas Public Water Supply Loan Fund (KPWSLF), also known as the State Revolving Loan Fund (SRF), for assistance in financing improvements to their systems. This Fund, which makes available low interest loans to water systems to help them finance improvements, is also administered by the Unit.
