LOG NAME: 60ANAEROBIC DIGESTER CLEANING SRVCS - SYNAGRO
SUBJECT
Authorize the Execution of Amendment No. 1 to the Contract with Synagro of Texas -CDR, Inc. for Anaerobic Digester Cleaning Services to
Provide for a Revised Renewal Language and Additional Funding in the Amount of $125,000.00 for a Revised Contract Amount of
$625,000.00 and Authorize a Revised Baseline Contract Amount of $625,000.00 for Subsequent Renewals (COUNCIL DISTRICT 5)
RECOMMENDATION:
It is recommended that the City Council:
1. Authorize the execution of Amendment No. 1 to City Secretary Contract No. 52747 with Synagro of Texas -CDR, Inc. for Anaerobic Digester
Cleaning Services, in the amount of $125,000.00, for a revised contract amount of $625,000.00 and a change to the timeline for renewals;
and
2. Authorize a revised contract base cost in the amount to $625,000.00 for subsequent renewals.
DISCUSSION:
On August 20, 2019, (M&C 19-0057) City Council authorized an agreement with Synagro of Texas CDR Inc. for anaerobic digester cleaning
services for the Village Creek Water Reclamation Facility (VCWRF). VCWRF continually operates fourteen (14) anaerobic digesters to treat
biosolids to be sent to the dewatering facility. Over time, digesters accumulate inert solids which take away usable treatment volume and impact
the quality of biosolids sent for dewatering and land application. Periodically cleaning the digester tanks removes untreatable materials and allows
for inspection and maintenance of components that are otherwise inaccessible.
The Water Department anticipated expenditures with Synagro-CDR Inc. to be in the amount of $500,000.00 to cover the cost of cleaning a
minimum of two digesters per year. Since October 2019, one digester (number 5) has been cleaned and Synagro began cleaning a second
digester. Digester 5 yielded 25% more solids than expected and incurred an overall cost of $350,000.00 ($100,000.00 over estimated budget).
Thus, the original funding is insufficient to complete the cleaning activities for the second digester this year. Additionally, based on this experience,
staff requires the flexibility to renew the contract upon the expiration of the funds and not just at the end of a year's term. The increased contract
capacity and flexible renewal term will apply to future annual renewals in case a similar higher volume of inert solids is encountered as the
remaining digesters are cleaned.
M/WBE OFFICE - A waiver of the goal for M/WBE subcontracting requirements was requested by the Purchasing Division and approved by the
Office of Business Diversity (OBD), in accordance with the M/WBE or BIDE Ordinance, because the purchase of goods or services is from
sources where subcontracting or supplier opportunities are negligible.
FISCAL INFORMATION / CERTIFICATION:
The Director of Finance certifies that funds are available in the current operating budget, as previously appropriated, in the Water & Sewer Fund to
support the approval of the above recommendation and execution of the amendment to the contract. Prior to an expenditure being incurred, the
Water Department has the responsibility to validate the availability of funds.
