Project Goals and Description. The Project involves replacing an aging water main near Xxxxxxxx Creek, with the goal of preventing potable water discharges that may adversely affect aquatic life. Cal Water will replace approximately 1,955 feet of existing cast iron pipe with polyvinyl chloride (PVC) pipe or polyethylene encased ductile iron pipe. Pipe sizes range from 8 to 16 inches. The PVC and polyethylene encased iron pipe material both have expected life span of about 100 years under normal use. Replacement of existing pipe will occur along Xxxxxxxx Road and the embankment of Xxxxxxxx Creek, near the confluence San Mateo Creek and Xxxxxxxx Creek in an unincorporated area of San Mateo County. The Project includes post-construction restoration, revegetation and stabilization of the work area to its native pre-construction condition. Completion of the Project may involve construction near and in jurisdictional water ways. Cal Water is responsible for compliance with State and/or federal regulatory permits and fees related to those jurisdictions, separate from its obligations under this ECA Project.
Project Goals and Description. The Smart Cover Installation Project has the following objectives:
a. To provide early detection and notification of collection system issues;
b. To reduce potential sanitary sewer overflow (SSO) events; and
c. To operate and maintain the collection system at design standards. This Smart Cover system monitors the flow levels within selected parts of the collection system which in turn can detect any significant level/flow anomalies. These anomalies could either be from plugged lines, high inflow and infiltration, or other restrictions. In any case, the Smart Covers will immediately notify City of Galt staff of impending problems thus affording staff enough time to respond and prevent a potential SSO event.
Project Goals and Description. The goal of the project is to update the 2014 CA-NV BMPs Manual, publicize the update, provide training on the updated BMPs Manual, and share the Discharger’s compliance system information with other drinking water systems operators (Operators) in order to standardize and facilitate compliance with the Statewide General Permit. The Discharger will provide proposed BMPs for incorporation into the BMP Manual, and the BMP Manual update will contain examples related to planned discharges and unplanned or emergency discharges, as outlined below:
a. Planned Discharges Due to:
Project Goals and Description. The goal of this project is to purchase, install, and make operational three sewer monitoring units consisting of manhole lids with continuous dynamic level sensors, early warning systems, detection loggers, and direct link transmitters. The District will purchase the three units and will install them in selected sewer line segments. The units will be placed where SSOs have occurred, where SSOs are likely to occur, or where the units may identify sources of inflow and infiltration. After installation, the District will use the units as a tool to collect data in various parts of the collection system, and may move the units to different locations within the collection system. The long-term goal is to minimize the risk of SSOs to surface waters.
Project Goals and Description. Task 1 – Conduct investigation and additional monitoring. Conduct additional water quality monitoring to investigate the source of BOD problems and to identify potential sources of FOG in the Facility’s influent. These measures will contribute to a reduction of BOD violations by providing more information about the source of the problem. Task 2 – Chemical Treatment. Chemically treat redworms, tubiflex worms, FOG, and BOD following recommendations provided by Aquafix, Inc. (a specialist in biotechnologies to improve sludge vitality and effectiveness in wastewater treatment plants). These measures will reduce or eliminate BOD violations by directly reducing BOD and by reducing sources of BOD problems. Task 3 – Upgrade tertiary filters. Drain and clean the tertiary filters, replacing the Task 4 – Develop operating procedures and source control measures. The Discharger is working with Xxxxxxx Engineering to conduct industrial user FOG inspections and develop a FOG source control program. These measures will reduce or eliminate BOD violations by reducing FOG in the Facility’s influent. In addition, the Discharger is working with PACE Engineering to develop operating procedures designed to improve FOG treatment, prevent recurrence of the worm infestation, and reduce BOD throughout the treatment process.
Project Goals and Description. The goal of this project is to improve EBMUD's ability to monitor chlorine residual levels in the potable water distribution system by purchasing and installing 15 new chlorine analyzers at potable drinking water distribution reservoirs. The analyzers can provide real-time chlorine data to operations staff.
Project Goals and Description. The Denitrification Pilot Study has the following objectives:
a. To ensure future compliance for Nitrates, the Calaveras County Water District (Settling Respondent) will conduct a Microvi Pilot Study to analyze this technology’s viability for long-term Nitrate removal.
b. A 5 to 10 gallon per minute (gpm) side stream will flow through the Microvi process for denitrification of Pond 4 effluent. Nitrate plus nitrite as (N) reduced to achieve below REC-002 (sampling location) permit limitations (10 mg/l monthly, 17 mg/l weekly average). Settling Respondent represents that Pond 4 effluent, one of 3 (Pond 4, Pond 6, or a blend of the two) sources of supply for the Copper Cove Reclaim Plant, is the key source of Nitrates being fed to the Reclaim Plant.
c. The evaluation of denitrification will inform the Settling Respondent’s next approach and will potentially improve the Reclamation Facility’s ability to supply Saddle Creek Golf Course’s discharge area with a better treated water supply.
Project Goals and Description. The goal of this project is to have a redundant filter at CSA 17 for ease of operations and maintenance. A new filter is being constructed as part of the base bid part of the project; however, the existing filter is obsolete, and replacement parts cannot be obtained. One filter is operated at all times and therefore cannot be taken offline for maintenance, as such Shasta County desires to include Additive Alternative A to the project to retrofit the existing filter. A redundant filter will allow for a filter to be taken offline annually for deep cleaning and other preventative maintenance thus maximizing filter useful life.
Project Goals and Description. The objective of the City of Colusa Wastewater Treatment Plant UV System Modifications and Optimization 2022 Project (Project) is to reduce effluent total coliform and ensure future compliance with effluent limitations for total coliform. The Project will consist of the following:
a. Line the UV Channels with Stainless-Steel Liners. The existing UV channel was constructed in 2007 and was originally coated with a high solids epoxy paint to minimize bacterial growth on the sides of the channel. Over time, this epoxy wears and regrowth can occur. A longer-term solution is to insert a thin stainless- steel liner within the channel.
Project Goals and Description. The project will provide sanitary and shelter- related units for the unhoused population in Modesto. The City’s unsheltered community tends to reside in City parks, trails, public spaces (adjacent to public roads), rivers (Tuolumne River and Dry Creek), and structurally unsafe hand-dug caves. While there are restrooms in some park locations, many of these areas have no access to appropriate sanitary facilities. The bridge housing project underway at 000 0xx Xxxxxx will create a living environment with up to 42 cabins that will provide temperature-controlled shelter space and will provide meals and sanitary facilities such as restrooms, showers, and laundry facilities. This SEP will focus on installing restrooms, showers, laundry units, and associated water and sewer infrastructure for this bridge housing project (SEP Units). The City has partnered with the County of Stanislaus (County), who will oversee the maintenance and upkeep of the SEP Units located at 000 0xx Xxxxxx, Xxxxxxx, Xxxxxxxxxx.
