AGENDA STAFF REPORT
City of West Covina | Office of the City Manager
DATE:June 18, 2019
TO:Mayor and City Council
FROM:David Carmany
Interim City Manager
SUBJECT:CONSIDERATION OF APPROVAL OF PURCHASE ORDER TO BIO CLEAN,
A FORTERRA COMPANY, TO INSTALL ADDITIONAL CATCH BASIN
FULL TRASH CAPTURE DEVICES
RECOMMENDATION:
It is recommended that the City Council authorize staff to issue a purchase order to Bio Clean, A
Forterra Company, in the amount of $57,022 for the purchase and installation of additional catch
basin inserts at various locations in the City.
DISCUSSION:
The City of West Covina is mandated by the Los Angeles Regional Water Quality Control Board to
implement best management practices (BMPs) as required by the City’s National Pollutant
Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) Permit.
The purpose of the BMPs is to minimize or prevent pollution discharges from entering the City’s
storm water system and eventually make its way to the ocean. Storm water runoff goes directly to
the ocean and is not like sewage that is collected and channeled through sewer lines to water
reclamation plants, treated and then released to the ocean. Thus, it is important to collect as much
debris (leaves, trash, etc.) as possible prior to entry into the storm drains, which is the purpose of
catch basin inserts.
There are several companies that make catch basin inserts, but there are differences in the way the
debris is collected and retrieved out of these capture devices. Staff has met with manufacturers of
catch basin inserts and researched various other collection devices available to determine the best
alternative for collecting debris before they enter our storm drain system.
The City presently has catch basin inserts installed at various locations in the City. The catch basin
inserts were manufactured by two different companies, Trash Guard (six units) and Bio Clean (six
units). The Trash Guard inserts were the first to be installed and required maintenance staff to enter
the catch basins for cleaning and necessitated confined space entry and additional staffing. Staff
experienced that those inserts were continually being blocked or plugged by debris preventing
proper water flow and allowing the debris to bypass the system and enter the storm drains. The
original catch basin inserts were removed after several years due to high maintenance costs and
because they were ineffective at preventing debris from entering the storm drains.
The Bio Clean catch basin inserts were installed in 2011, and maintenance staff has experienced
great results with these devices, as they effectively capture the debris, allow continual water flow,
and provide easy access for cleaning. Staff has determined that when compared to the other catch
basin manufacturers, Bio Clean catch basin inserts are the most efficient at filtering and collecting
debris while minimizing the maintenance burden on staff. There are several key areas that the Bio
Clean catch basin inserts differ from others:
•The Bio Clean catch basin inserts have a unique design that includes both a filtration basket
and a “shelf system”. This “shelf system” positions the filtration basket directly under the
manhole for easy access. As a result, the Bio Clean catch basin filter is the only available
insert that can be cleaned without entering the catch basin. This reduces the staff time
required to maintain the filter by up to 75 percent. It also eliminates the need for confined
space entry, thus minimizes any related safety issues and additional staff.
•The “shelf system” is patented by Bio Clean and is the sole source provider of this style of
catch basin insert.
•Bio Clean offers an eight-year unlimited warranty on its product. Other manufacturers only
offer warranties between one and five years.
•The Bio Clean filter is designed to capture high levels of trash and litter, grass and foliage,
sediments, hydrocarbons, grease and oil. In addition to the multi-stage filtration device, the
unit reduces pollutant loads and has been approved by the Regional Board as a “full trash
capture” device due to its removal of 100% of trash and debris 5 mm and greater.
In accordance with Chapter 2, Section 2.05 of the Uniform Public Construction Cost Accounting
Act, public works projects of $60,000 or less may be performed by employees of the public agency
by force account, by negotiated contract or by purchase order. Staff is recommending that the City
Council approve the purchase order to Bio Clean, A Forterra Company in the amount of $57,022 for
the installation of 21 catch basin inserts at the following locations:
Locations Length
1 North bound Azusa Avenue, North of the 10 freeway 5’ long
2 West Bound on Garvey Avenue North, at the Mercedes Benz Dealer 36’ long
3 West bound on Garvey Avenue North, across from McDonalds 10”

6 North bound Azusa Avenue, 20’ North of Garvey Avenue North 30’ long
7 North bound Azusa Avenue, 30’ North of Garvey Ave North 30’ long

14 North bound Azusa Avenue, 30’ South of Merced Avenue 30’ long
15 North bound Azusa Avenue, 20’ South of Vine Avenue 22’ long

19 East bound Cameron Avenue at Azusa Avenue 36’ long
20 West bound Cameron Avenue at Azusa Avenue at bus stop (two catch basins)30’ long
Staff is recommending that the Bio Clean catch basin inserts be the future standard for storm water
capture devices, due to a patented “filter shelf collection” system, low maintenance costs and
standardization of parts and materials for future repairs.
