Water System Master Plan - Woodside Mutual Water Company, CA
![]() |
Located in the Woodside Hills, the Woodside Mutual Water Company (WMWC) is comprised of 48 property owners with an average property value of over $2 million. The existing water system supplying these homes consisted of 2-inch steel pipes installed over 50 years ago and were showing visible signs of deterioration resulting in frequent repairs. There was also concern that these pipes may experience catastrophic failure over the next few years. The majority of the pipes were located in highly vegetated, steep, cross country terrain making accessibility for repairs extremely difficult. The WMWC purchases all of its water from the California Water Service Company (Calwater) and anticipated that after the upgrades were completed Calwater would take over their facilities.
The WMWC retained Pakpour Consulting Group to develop a water system master plan, which consisted of mapping the existing distribution system and developing several design alternatives to completely upgrade the system. The proposed system included new 6 to 8-inch water mains, fire hydrants, pumps and storage facilities. Extensive coordination with both the WMWC and Calwater was a priority during the preliminary design to ensure that the design alternatives met the requirements of Calwater.

As with any project being funded by property owners, the cost benefit of any improvements were a top priority for the study team. With anticipated construction costs in the range of $3.5 million, it was essential to maximize every dollar spent in construction. Pakpour Consulting Group took a hands on approach to developing the alternatives by conducting multiple field walks with WMWC staff to determine the best alignments along with attending WMWC board meetings in order to find the most practical, cost effective solution for upgrading the system.
