WATER SYSTEM INFORMATION
1. Water service can be provided by service connection to an existing 8” diameter water main that is on feet from the site.
2. If existing onsite water main/easement conflicts with new building(s) proposed or if upsizing of existing LWSD water main is
required to meet onsite fire flow requirements or if new/additional/re-located fire hydrants are required, water service for
the site will require an improvement to LWSD’s water distribution system of:
a. TBD feet of 12” diameter water main to reach the site (fire flow); 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);
b. Proof or reservation of easement(s) as required by LWSD;
c. Other: LWSD Service Connection application required, for any new/modified service connection.
Comments/special conditions: Service pressure(s) greater than 80 psi indicated, Pressure Reducing Valve(s) indicated, contact local
building official for requirements &/or additional information.
The nearest fire hydrants are on the Property (as shown on map on the back of this page).
System hydraulic model results (FF #426), at no less than 20 psi, indicate that LWSD’s standard maximum allowable liquid velocity
of 10 ft/s is exceeded in the existing water main system at a fire flow rate above 3,100 GPM. 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.
450 Pressure Zone Est. Meter Elevation(s)-GIS: 217+/- Est. Pressure Range at Meter(s) (psi): 99-101
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.

SEWER SYSTEM INFORMATION
1. Sewer service can be provided by service connection to an existing 6” diameter low-pressure sewer main that is on the site
and the sewer system has the capacity to serve the proposed land use.
2. Sewer service for the site will require an improvement to LWSD’s sanitary sewer system of:
a. feet of ” diameter sewer main or trunk to reach the site; and/or
b. The construction of a sanitary sewer collection system on the site; and/or
