SYSTEM STATUS UPDATE – January 06, 2014

Customers of Waimanalo Irrigation System:

Progress on the improvements to the Maunawili Ditch system has reached 85% to 95% completion and the recent rainfall has helped the Waimanalo Reservoir to achieve full capacity.  The improvements included installation of a 700 foot siphon which bypassed approximately 1,200 linear feet of the 100-year old open earthen ditch.  Additionally, approximately 7,000 linear feet of existing earthen ditch has been re-lined with a high density polyethylene half pipe to eliminate seepage and leaks.  Final phases of a SCADA/Telemtry system (Supervisory Control and Data Acquisition) is being installed and will be tested over the next several months.  The data collected by the SCADA system will assist staff in identifying potential deficiencies throughout the ditch system and alert staff to abnormal conditions due to heavy rainfall or high wind conditions.

The Department of Agriculture has established a “link” on our website so you may track the progress of the irrigation system’s availability of irrigation water.  The link will provide a daily reservoir level, National Weather Service information and staff’s comments on the condition of the Waimanalo Irrigation System.  Our website address is: http://hdoa.hawaii.gov/arm/irrigation-systems/waimanalo-irrigation-system-water-level/

NOTE:  Pursuant to §4-157-12, Discontinuance of service. – Water service may be refused or discontinued by the department if the water bill has not been paid within thirty days after the mailing or presentation thereof or if the consumer fails to comply with any of the applicable rules.  However, acreage assessments shall continue in spite of the discontinuance of service.
