18 AAC 80.205. Engineering plans

(a) Engineering plans submitted for approval under 18 AAC 80.200 must include

(1) a completed application, on a current form provided by the department;

(2) construction drawings and specifications, for the water source, storage, distribution, and treatment systems and related structures;

(3) plans and profiles of the water mains, as applicable;

(4) design criteria, calculations, and flow analysis computations for water demand, storage tank sizing, distribution main sizing, pump sizing, and other components of the new public water system if requested by the department to ensure that the design is adequate; and

(5) a specification that at least 20 psi of service pressure at the highest elevation or pressure zone of a distribution main be maintained under peak design demand.

(b) The plans for each Class A or B public water system must include

(1) the fee required under 18 AAC 80.1910(c);

(2) data showing the capability of the public water system source to meet minimum water consumption needs, criteria for water demand calculations, and the production capability of the water plant;

(3) the location, stated as the horizontal position and elevation, of each proposed or existing wastewater treatment and disposal system, sewage pump station, sewer line manhole and cleanout, petroleum storage tank and line, and potential or actual source of pollution or contamination, including the sources listed in Table A in 18 AAC 80.020(a) , within 200 feet of a proposed water source, regardless of property lines or ownership;

(4) the location, in longitude and latitude to the closest second, of each well and surface water intake and the method used to determine longitude and latitude on a form provided by the department;

(5) the overall treatment scheme, including calculations, if required under 18 AAC 80.600 - 18 AAC 80.699, for disinfection and how Giardia lamblia and viruses will be removed or inactivated;

(6) the name, address, telephone number, and facsimile number of the owner or operator;

(7) a specification that only lead-free pipe, flux, and solder will be used, as required by 18 AAC 80.500;

(8) for a public water system that uses compressed air to pressurize hydropneumatic tanks, information proving that air quality will not contribute contaminants to the water;

(9) other information that the department determines is necessary to assess compliance with this chapter; and

(10) documentation showing the existence or formation, before beginning construction of the system, of a local government organization, a homeowner's association, a private utility, a commercial entity, or other entity, the purpose of which is to operate and maintain the system.

(c) In addition to the information required by (a) and (b) of this section, the owner or operator shall submit the following information:

(1) for a Class A or Class B public water system proposing to make a change in the water treatment process that could change water quality, such as adding new chemicals, changing the filtration process, or changing the disinfection process,

(A) the water quality test results for raw water and treated water that identify the contaminants listed in 18 AAC 80.300 and important to the design of the treatment process; and

(B) after construction, the effectiveness of the treatment;

(2) for a public water system proposing to use a new source, the results of raw water testing, conducted before operation, as shown in Table B of this paragraph; and

Table B. Minimum Raw Water Testing Requirements for a System

Proposing to Use a New Water Source

Total Coliform Bacteria Yes Yes Yes Yes Yes Yes Inorganic Chemical (not including asbestos) Yes Yes No No No No Nitrate Yes Yes Yes Yes Yes Yes Volatile Organic Chemical Yes Yes No No No No Secondary Contaminants Yes Yes No No No No

(3) for a Class A or Class B public water system that has a new water source that is

(A) a groundwater source, raw water quality data sufficient for the department to determine whether the source is GWUDISW;

(B) surface water or GWUDISW, raw water quality sufficient to allow the department to determine whether the proposed water treatment equipment complies with 18 AAC 80.600 - 18 AAC 80.680;

(4) for a Class A public water system that will serve a resident population of 10,000 or more individuals and whose owner or operator plans to add a disinfectant to the water in any part of the drinking water treatment process, raw water quality data sufficient for the department to determine whether the public water system will comply with 18 AAC 80.300(b) (2)(C);

(5) for a Class A public water system, raw water quality data sufficient to allow the department to determine whether the proposed water treatment equipment will control the corrosivity of the water;

(6) for all public water systems, raw water quality data for a potential contaminant, if the department determines that the data serves the interest of public health.
