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.

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.

Video Inspections Prioritize Sewer Repairs

  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 207-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 had only poor-quality video recordings or none at all.

Solution: A specialty contractor, National Plant Services, cleaned and inspected 350,000 feet of these older pipelines in Dublin and San Ramon (see map below). Instead of taking several years, the work was completed in a single year, finishing in June 2017.

With a wealth of new pipeline condition data, the District can forecast future replacement costs more accurately and prioritize cost-effective maintenance and repairs before pipes fail. The $450,000 project was funded by sewer service charges paid by District customers.

No Digging Needed

No digging is needed to clean and inspect sanitary sewers. 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.
