WATER SYSTEM INFORMATION
1. Properties are currently served by ‘temporary’ water service connections to City of Milton’s water system.
2. New water service for the site will require an improvement to LWSD’s water distribution system of:
a. 670+/- feet of 8” and/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);
b. Proof or reservation of easement(s) as required by LWSD;
c. Other: LWSD Service Connection Application required, for any new 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 LWSD fire hydrant is over 900+/- feet from the Property (as shown on map on the back of this page).
Fire Flow at no less than 20 psi available within LWSD’s existing water distribution system is a minimum 1,000 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.
450 Pressure Zone Est. Meter Elevation(s)-GIS: 200+/- Est. Pressure Range at Meter(s) (psi): 106-108
I hereby certify that the above water system information is true. This certification shall be valid for one (1) year from the date of
