The Water Operations Department is responsible for the operation and maintenance of the District's 71.6 square mile service area, which serves approximately 40,000 customers with 9,865-meter connections, over 200 miles of pipeline and over 75 miles of wastewater collections. RMWD imports 100% of retail domestic water from San Diego County Water Authority. Operations consists of four divisions, Plus Electrical and Pump & Motor Staff as summarized below:
Meter Services Division
The Meter Services division has four staff members who are responsible for the majority of customer service inquiries: meter reading, meter repair, meter installation, meter replacements, and meter box leaks. Currently the meter system infrastructure has approximately 9,865-meter connection services that are divided into seven reading routes, which are read on a monthly and bi-monthly basis.
Historically the agency meter infrastructure was comprised of various types of meter manufacturers. During the past two years (2016) the Board elected to improve consistency and authorized staff to move forward with implementing a single meter manufacturer with AMR reading capability. The AMR meter infrastructure will improve metering efficiencies and provide staff the ability to work on a variety of critical maintenance tasks.
The Systems division has four staff members who are responsible for the operation of the water distribution system: the purchase of potable and non-potable water, monitoring water quality and maintaining the most optimum level of operation throughout the entire distribution system. The daily flows average 1.9 MGD during the winter and 6.0 MGD during peak summer demands.
The District is mandated by State and Federal regulations to preform multiple water quality analyses and submit reports to the Regional Water Quality Control Board (RWQCB) on a monthly, quarterly, and tri-annual basis. The parameters are as follows: Bacteria, HPC, Nitrate, Nitrite, pH, Temp, THM’s HAA5’s and Lead & Copper. The District has 25 routine sample stations throughout the service area and all stations are sampled via a scheduled sampling plan approved by RWQCB.
- The distribution system consists of three service wholesale connections: two treated and one untreated
- 11 pump stations with a total of 53 pumps with a range of 10 to 900 hp, with pumping rates of 180 to 2700 gallons per minute
- 18 reservoirs: 13 potable with capacity of 6,000 to 10,000,000 gallons and 5 non-potable which includes Lake Ramona at 730 million gallons
- 22 pressure control stations with the ability to reduce pressure from 336 psi to 60 PSI
- 2 residual boosting stations
- 25 sample stations
- 24/7 call team
The Utilities Division has seven staff members who perform skilled tasks to District distribution infrastructure: pipeline installation, new customer meter service connections, Emergency pipeline repairs, fire hydrant replacements, review of new District and developer construction projects, Underground Service Alerts (USA), valve exercise program, fire hydrant maintenance program, easement maintenance, and 24/7 customer service response.
The District system consists of over 200 miles of water pipelines with 4” to 30” diameters and multiple materials like cast iron, concrete cement lined, c-900 PVC, and asphalt coated steel. The Utilities staff is required to be versatile with various types of heavy equipment: dump trucks, backhoe, skip loader, steer bobcat, utility trucks and water trucks, as well as a variety of hand tools.
The Collections division has four staff members who are responsible for the day-to-day maintenance of the collections system (sewer). The collections system is comprised of the San Vicente and the Santa Maria service areas, two separate funding systems. The collections systems consist of 5 operating lift stations, 1,545 manholes, 75 miles of pipelines. San Vicente System is 6.6 square miles of service area and Santa Maria System is 8.8 square miles of service area.
The activities are to keep the system clear of debris, which prevents waste from overflowing onto public streets and entering blue water streams. After a section of the system has been cleaned, it is viewed via video to ensure all debris has been removed and to inspect for pipeline cracks, voids, and infiltration.
Electrical-Pump & Motor
The electrical and pump & motor maintenance has two staff members who are shared between the Water Operation department and the Wastewater Treatment Plants. The electrical member is responsible for ensuring all electric equipment is maintained for optimum performance and all equipment meets NFPA standards. The staff member reviews schematics for new and existing motor control centers, variable frequency drives, disconnects motors from power sources, troubleshoots electrical issues, and coordinates electrical vendors as needed.
The pump & motor technician has the responsibility of addressing any issues pertaining to the majority of mechanical issues for both water and wastewater facilities. The staff member has the knowledge of working turbine, centrifugal, submersible, natural gas combustion, and split case pumps and many types of mechanical seals. In all there are 53 water pumps, 12 collection pumps and multiple submersible pumps within the two wastewater treatment facilities.
