approval for smoke flier content. The City shall provide any available information regarding <br />community groups in the study area and shall provide facilities for and representation at any public <br />meetings regarding the smoke testing operations. <br />Deliverables: Electronic and hard copy deliverables provided in Task 13 — Draft Report. The <br />report will provide tabular and graphical listings of inspected system assets and the location and <br />type of defects. Both hardcopy and electronic formats shall be provided. The electronic data shall <br />be in Microsoft Access 2007 format. <br />Task 5 — Dyed Water Flooding /Leak Quantification <br />This task consists of identifying interconnections, pinpointing inflow sources and quantifying <br />selected collection line, manhole, and service line leaks that were identified from the results of <br />previous tasks. Quantification estimates are based on field measurements and empirical values <br />developed from past experience. Leak quantification will also be performed using portable weirs <br />or hydrostatic devices in conjunction with dye water flooding. The dyed water testing is digitally <br />recorded. This information is then used to evaluate 1/1 rates and compare to flow monitoring <br />results to determine quantities of 1 /I. A portion of the dye flooding will be performed in conjunction <br />with Closed Circuit Television Inspection activities. <br />Assumptions: A maximum of 10 locations shall be flooded and /or quantified using this method <br />without request for additional compensation. <br />Required from Others: None. <br />Deliverables: Electronic and hard copy deliverables provided in Task 13 — Draft Report. The <br />report will provide tabular and graphical listings of flooded /quantified system assets. Both <br />hardcopy and electronic formats shall be provided. <br />Task 6 — Flow Isolation <br />This task consists of dividing the major basins into smaller areas (2,000 -5,000 L.F.) and taking <br />weir readings during minimum flow periods (11 p.m. — 6 a.m.) to determine if infiltration rates from <br />groundwater require additional investigation. <br />Assumptions. A maximum of 10 locations shall be isolated using this method without request for <br />additional compensation. <br />Required from Others: None. <br />Deliverables: Electronic and hard copy deliverables provided in Task 13 — Draft Report. The <br />report will provide tabular listings of locations showing evidence of significant groundwater <br />infiltration. Typically, these line segments would be included in the listing of recommended <br />pipeline for internal television inspection. Both hardcopy and electronic formats shall be provided. <br />Task 7 — Sanitary Sewer Main Cleaning <br />This task consists of preparing the sewer lines to be internally inspected by cleaning the pipe walls <br />to provide for unobstructed internal inspection. ENGINEER will perform an analysis of the <br />collected field data to prepare a listing of sewer lines requiring television inspection for approval by <br />the City. The cleaning will be accomplished by use of a hydraulic cleaning unit with all lines to be <br />internally inspected to be cleaned prior to internal inspection. It is the intent of the cleaning to <br />flush the sludge, mud, sand, gravel and other sediment and debris down the sewer line. All <br />debris, sediment and sludge removed from the sewer lines will be disposed of at a permitted site <br />designated by the City. <br />City of San Marcos, Texas Portions of <br />Basins 10 Assessment Page 4 <br />Project Work Plan <br />11/8/2011 <br />
