<br />REOUESTIR CITY COUNCIL AGENDA ITEM e <br /> <br />Agenda Date Requested: <br /> <br /> <br />Requested By: S. Gillett epartment: Public Works <br /> <br />_ Report _ Resolution XX Ordinance <br /> <br />Exhibits: <br /> <br />Ordinance No. 00- <br />Agreement for Engineering Services <br /> <br />SUMMARY & RECOMMENDATION <br /> <br />The FY 1999-2000 Utility ClP budget includes an engineering evaluation of the Little Cedar Bayou Wastewater Treatment <br />Plant belt press to detennine replacement alternatives. The belt press is used to dewater sludge prior to final disposal. The <br />original project included an engineering evaluation of the unit to detennine the best location and size of the proposed <br />replacement. <br /> <br />After discussions with several engineering finns, it was detennined that the entire solids handling process should be <br />examined. The original dewatering equipment and structures were constructed in 1981, and construction of additional <br />digester capacity was included in the 1986 expansion of the Plant. With increasing solids loading at the Plant in the past few <br />years, detention time in the digester has been reduced, increasing the amount of solids per volume of wastewater treated. <br /> <br />The proposed engineering study has been expanded to include an examination of the entire solids handling process, <br />including digester size, thickener size and location and the belt press size and location. The proposed study will examine the <br />need for additional sludge handling capacity, as well as the physical location of needed improvements to confonn with the <br />future expansion plans. Request for Qualifications (RFQ) were received and reviewed by staff, with the finn of Camp <br />Dresser & McKey (CDM) was selected as the top respondent. A scope of work was developed, and CDM has submitted a <br />proposed contract for consideration. The total estimated cost for these services is $49,780, and will not be exceeded without <br />written authorization. A total of $50,000 is budgeted in the FY 1999-2000 budget for this Project. <br /> <br />Action Required by Council: Approve Ordinance No. 00- authorizing the City Manager to execute an agreement <br />with Camp Dresser & McKey for the Little Cedar Bayou Wastewater Treatment Plant Solids Handling Study. <br /> <br />Availability of Funds: <br /> <br />General Fund WaterlWastewater <br />X Capital Improvement_ General Revenue Sharing <br />Other <br /> <br />Account Number: 003-9890-819-1100 Funds Available: X YES NO <br /> <br />Approved for City Council Aeenda <br /> <br />A~ T. \..\~ <br />Robert T.
