Distribution System Site Visits - March 24, 2005General Notes• Need to consider the Siesta Key Utilities Authority, which the County will acquire in July2006. This will include tanks, distribution lines, etc. Comprises ~3500 customers.• The auto flushers at the north sites discharge 4-10 MG per month.• According to nodes shown by SCADA system at PS2, the pressure in the system at~8am was 50-65 psi.• The system has 15 pressure nodes that are monitored. Some are at key intersections ornear key intersections. County just added one at Palmer Ranch and would like to addmore to Siesta Key when they take over SKUA.• Current SCADA system at PS2 uses a Dynac software system. County wants toupgrade the whole system to Wonderware eventually.H:\Client\SAR Co_SAR\6873C00 WATER SUPPLY MASTER PLAN UPDATE\Deliverables\TM 2 - Water System Assets\Final\Appendix F -Final.doc
Distribution System Site Visits - March 31, 2005General Notes• Some of the empty tanks were filled last year prior to the hurricanes.• Currently have the Dynac SCADA system installed at all facilitys except at VeniceGardens WTF, and aside from the WonderWare trial package being installed at PS1.This current software has done well for the County, but it has a few “bugs.” The clock isnot set to the correct time, and it cannot be adjusted. Often, the operators find that ifone parameter is altered or fixed, another parameter stops working. The County wouldlike to eventually install WonderWare at all the pump stations and facilities.• In the past with the old control system, PS6 could control the Carlton WTF in case ofstorm or other problem at Carlton. With the new system, they can’t do this. It is theopinion of the operators that the County should reinstate the ability to control Carltonfrom PS6.• Pump Stations 1, 2, 4, and 6 have the ability to be booster stations. Pump Stations 3and 5 are high service stations only. It is the opinion of the operators that it would bebeneficial to convert PS3 and PS5 to booster stations.• It is the operator’s opinion that the most important project to be done in the system is toupgrade the degasification system at University WTF.• Chlorine demand increases dramatically in the summer months. Example: at Universitythe chlorine feed has increased from 9 to 13.5 gallons per hour in the past 2 weeks.• SKUA typically purchases 50-70 MG per month.• SKUA used to sell to Casey Key. When the County took over the Casey Key system,they turned the meters around and now sell to SKUA.• As far as operators know, the County has not bought from or sold to the City of<strong>Sarasota</strong> since 1993.• A few years ago, the meter crew took over the maintenance of the County’s watersystem interconnects.• SKUA interconnects with City of <strong>Sarasota</strong> are in poor condition. The valve pits arecompletely submerged in water. Pits are equipped with sump pumps that were notoperating. Severe corrosion was noted in both pits.H:\Client\SAR Co_SAR\6873C00 WATER SUPPLY MASTER PLAN UPDATE\Deliverables\TM 2 - Water System Assets\Final\Appendix F -Final.doc
