Every principal use and every lot within a subdivision shall be served by a water supply system that is adequate to accommodate the reasonable needs of such use or subdivision lot and that complies with all applicable health regulations.
(a) 
Primary responsibility for determining whether a proposed development will comply with the standard set forth in Section 14.60.300 often lies with an agency other than the city, and the developer must comply with the detailed standards and specifications of such other agency. The relevant agencies are listed in Subsection (b). Whenever any such agency requires detailed construction or design drawings before giving its official approval to the proposed water supply system, the authority issuing a permit under this chapter may rely upon a preliminary review by such agency of the basic design elements of the proposed water supply system to determine compliance with Section 14.60.300. However, construction of such system may not be commenced until the detailed plans and specifications have been reviewed and any appropriate permits issued by such agency.
(b) 
In the following if-then list, the if statement describes the type of development and the then statement indicates the agency that must certify to the city whether the proposed water system complies with the standard set forth in Section 14.60.300.
(1) 
If: The use is located on a lot that is served by the Snohomish County Public Utility District No. 1 (PUD) water system or a previously approved, privately owned public water supply system and the use can be served by a simple connection to the system (as in the case of a single family residence) rather than the construction of an internal distribution system (as in the case of a shopping center or apartment complex):
Then: No further certification is necessary.
(2) 
If: The use (other than a subdivision) is located on a lot that is served by the PUD water system but service to the use necessitates construction of an internal distribution system (as in the case of a shopping center or apartment complex); and
a. 
The internal distribution system is to be transferred to and maintained by the PUD.
Then: The PUD must certify to the city that the proposed internal distribution system meets PUD specifications and will be accepted by the PUD.
b. 
The internal distribution system is to be privately maintained:
Then: The public works director must certify that the proposed collection system is adequate.
(3) 
If: The use (other than a subdivision) is located on a lot not served by the PUD system or a previously approved, privately owned public water supply system; and
a. 
The use is to be served by a privately owned public water supply system that has not previously been approved:
Then: The Washington State Department of Ecology (DOE) must certify that the proposed system complies with all applicable state and federal regulations. (A "Permit to Construct" must be obtained from (DOE.) The DOE must also approve the plans if the water source is a well and the system has a design capacity of 100,000 gallons per day or is located in certain areas designated by DOE. The PUD must also approve the distribution lines for possible future addition to the city system.
b. 
The use is to be served by some other source (such as an individual well):
Then: The Snohomish County Health Department must certify that the proposed system meets all applicable state and local regulations.
(4) 
If: The proposed use is a subdivision; and
a. 
Lots within the subdivision are to be served by simple connection to existing city lines or lines of a previously approved public water supply system:
Then: No further certification is necessary.
b. 
Lots within the subdivision are to be served by the PUD system but the developer will be responsible for installing the necessary additions to such system:
Then: The PUD must certify to the city that the proposed system meets PUD specifications and will be accepted by the PUD.
c. 
Lots within the subdivision are to be served by a privately owned public water supply system that has not previously been approved:
Then: The Snohomish County Health Department (SCHD) must certify that the proposed system complies with all applicable state and federal regulations. (A "Permit to Construct" must be obtained from DOE.) The Washington State Department of Ecology (DOE) must also approve the plans if the water source is a well and the system has a design capacity of 100,000 gallons per day or is located within certain areas designated by DOE. The PUD must also approve the distribution lines for possible future addition to the PUD system.
d. 
Lots within the subdivision are to be served by individual wells:
Then: The Snohomish County Health Department must certify to the city that each lot intended to be served by a well can be served in accordance with applicable health regulations.
