Sound Planning and Appropriate Investments
The Capital Improvement Program (CIP) is integral to accomplishing the District's mission and strategic plan. In fiscal years 2018 and 2019 DSRSD is investing $66 million in replacement and expansion projects needed to:
- protect human health and the environment
- maintain and rehabilitate existing assets
- respond to regulatory requirements
- accommodate planned future growth
The cost of replacing existing assets is built into the charges current customers pay for water and sewer services. Developers pay for expanding water and wastewater systems on behalf of future customers. Developer fees also purchase capacity in the community's existing infrastructure.

Sewer Cleaning & Inspection
|Our hydro-cleaning trucks use recycled water to flush grease and roots from sewer mains to clean the pipes and prepare them for inspection.
|Working at the bottom of a manhole, a DSRSD wastewater operator lowers a robotic video camera into a sewer pipe.
Situation: District employees clean and video-inspect about 10 percent of the 206-mile wastewater collection system every year. Using the recordings, we rate the condition of every pipeline according to national standards. For many sewer lines installed before 2000, however, we have only poor-quality video recordings or none at all.
Solution: DSRSD and its contractor, National Plant Services, are cleaning and inspecting 350,000 feet of these older pipelines in Dublin and San Ramon (see map below). Instead of taking several years, the work will be done by mid 2017.
Using video recordings of the inside walls of each pipe, we are prioritizing maintenance and planning for future sewer replacements. The $450,000 project is funded by sewer service charges paid by District customers.
No Digging Needed
Working through existing manholes, the crew uses recycled water to flush the sewer pipes that run under the middle of the street. Flushing removes grease and roots that can cause clogs and sewage overflows. Then the crew sends a closed-circuit video camera through the pipe to record its condition.
Occasionally people hear gurgling noises or splashing in their toilets during hydro-cleaning. This is normal and doesn’t affect household plumbing. Most customers notice nothing at all. Work at each manhole typically takes less than an hour. Traffic controls are short-term.
