Chair and Board Members, Hesperia Water District
FROM:
Rachel Molina, City Manager
BY:
Cassandra Sanchez, Director of Public Works/City Engineer Jeremy McDonald, Water Operations Manager
SUBJECT:
D&H Water Systems – Increase to Contract
RECOMMENDED ACTION
It is recommended that the City Council and Board Members of the Hesperia Water District authorize the City Manager to amend the agreement with D&H Water Systems in the amount of $15,000 in the new not-to-exceed amount of $101,405, for the purchase of calcium hypochlorite chlorine.
BACKGROUND
The Hesperia Water District disinfects the water that is pumped from the ground to control microbial contaminants and comply with State and Federal water quality regulations, which are set by the State Water Resources Control Board (SWRCB) and the Environmental Protection Agency (EPA). Chlorine is used to disinfect the groundwater and is treated at each well site. The required chlorine residual is 0.2 to 4.0 parts per million (ppm), and the District has continued to meet these standards with an average of 0.7 ppm as stated in the District’s 2024 Annual Water Quality Report.
ISSUES/ANALYSIS
At the Board of Directors meeting on June 17, 2025, the Board approved a contract with D&H Water Systems in the amount of $86,405, which included a 10% contingency. Staff have determined that additional authority will be needed for the purchase of additional calcium hypochlorite for the current Fiscal Year.
The chlorine injection equipment at well sites is designed to use a specific chlorine tablet, known as Constant Chlor Plus Briquettes. These are supplied by D&H Water Systems, Inc., who are the sole distributor of this product.
