WATER SYSTEM INFORMATION
1.Water service can be provided by service connection to an existing 12” diameter water main that is approximately +/-40
feet from the site.
2.Water service for the site will require an improvement to LWSD’s water distribution system of:
a. 40 feet of 8-12” diameter water main to reach the site; and/or
b. The construction of a water distribution system on the site; and/or
c. A major portion of LWSD’s comprehensive water system plan would need to be implemented and/or
constructed; and/or
d. Other (describe): On-site water improvements and Developer Extension Agreement required if On-site hydrants
required.
3.a. The existing water system is in conformance with LWSD’s Comprehensive Water System Plan.
b. The existing water system is not in conformance with LWSD’s Comprehensive Water System Plan and an
Amendment to this Plan will be required. This may cause a delay in issuance of land use approvals or permits.
4.a. The subject property is within the corporate limits of Lakehaven Water & Sewer District, or has been granted
Boundary Review Board approval for extension of water service outside of LWSD’s water service area.
b. Annexation or Boundary Review Board approval will be necessary to provide service.
5.Water service is subject to:
a. Payment of connection charges (to be determined by LWSD);
b. Proof or reservation of easement(s) as required by LWSD if On-site water improvements required;
c. Other: The existing 2-5/8” setters should be evaluated under UPC & LWSD standards, to determine if it’s
adequate for the proposed use. LWSD Service Connection Application required, for any new/modified service
connection..
Comments/special conditions: .
The nearest fire hydrant is approximately 40+/- feet from the Property (as marked on map on the back of this page).
System hydraulic model results (FF #), at no less than 20 psi, indicate that LWSD’s standard maximum allowable liquid velocity of 10
ft/s is exceeded at a fire flow rate above 2500 GPM for two (2) hours or more. This flow figure depicts the theoretical performance of
the water distribution system under high demand conditions. Fire flow rates greater than this may be accommodated through water
distribution system improvements, contact LWSD for additional information.
578 Pressure Zone Est. Meter Elevation(s)-GIS: High 424+/-, Low 412+/- Est. Pressure Range at Meter(s) (psi): 64-78
I hereby certify that the above water system information is true. This certification shall be valid for one (1) year from the date of
signature.
