2011 - 2016 Capital Improvement Program
| Project #8026, Septage Management | |
Description: Several changes to the Hauled Liquid Waste Management Program have been implemented to improve the control of discharges to the MDS, protect the infrastructure, improve security, and capture appropriate revenue. Under this project, the current septage site in Chanhassen is being upgraded to meet program requirements. New septage receiving facilities have been constructed at the Blue Lake and Empire Plants. In 2009, the septage facility the MCES purchased in Fridley replaced four septage sites in the north metro area. |

The MCES provides for the collection and treatment of hauled liquid wastes at designated receiving sites around the region. The Council has assumed this responsibility to assure proper treatment of septage and other hauled liquid wastes originating from communities within the metropolitan area. During 2003, MCES completed a study to evaluate the effectiveness of this system and the impact that hauled liquid wastes has on the treatment system to determine the most efficient and cost effective method for treatment and disposal. The study concluded that the Hauled Liquid Waste Program should assure sufficient regulation of discharges to protect the Metropolitan Disposal System (MDS) infrastructure and improve security. To accomplish this, hauled liquid waste will only be accepted at Council designated “official receiving sites.” These receiving sites will have the following attributes:
• Secured access – Gates allowing only permitted haulers to enter and use site
• Means for recording loads discharged – Electronic (preferred) or paper system to capture data about the hauled waste discharged
• Means for sampling – Provision to hold waste prior to discharge (large enough for a representative sample)
• Means for volume measurement – Scale or flow meter to measure incoming truck weight or volume discharged
Furthermore, disposal of hauled liquid wastes will be restricted to treatment plants unless provisions are made to control the waste strength during its introduction into the interceptor system. Dilution should be sufficient to minimize the risk of odor and corrosion. Additionally, any disposal site located on the interceptor will not be located where excess sediment, hydrogen sulfide, or corrosion are already present (or in close proximity to flat sloped sewers, force mains, or other unfavorable situations).
The hauled liquid waste sites are located in Chanhassen and Fridley and at the Metro, Blue Lake, and Empire Plants.

There will be additional O&M
costs associated with running and cleaning out the new septage receiving
sites. The estimated annual cost for these services is $67,500. The
estimated cost for additional sampling, monitoring, and administration
of the new sites is $105,000. However, this project will reduce the
need to clean and premature deterioration of the existing sanitary
sewers in which the septage is dumped.
