WATER SYSTEM INFORMATION
1. Water service(s) can be provided by service connection(s) to an existing 12” diameter water main that is approximately
20+/- feet from the site.
2. Water service for the site will require an improvement to LWSD’s water distribution system of:
a. 20+/- feet of 8” &/or 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): LWSD Developer Extension (DE) Agreement 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, for any new/modified service connections);
b. Proof or reservation of easement(s) as required by LWSD;
c. Other: LWSD Service Connection Application(s) required, for any new modified service connection(s). LWSD DE
Agreement (#2 above) project must be accepted by LWSD, prior to any new service connection activation(s).
Comments/special conditions: Service pressure(s) less than 40 psi indicated, Booster Pump recommended, contact local building
official and LWSD for requirements &/or additional information.
The nearest existing fire hydrants are approximately 5+/- feet from the Property (as marked on map on the back of this page).
Fire Flow at no less than 20 psi available within the water distribution system is a minimum 2,500 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: 500+/- Est. Pressure Range at Meter(s) (psi): 31-39
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.
