The MTWD ensures compliance with the water quality standards as set out in the Philippine National Standards for Drinking Water 2007 issued by the Department of Health. To ensure compliance, testing of water at source and in consumer faucets are regularly done to monitor the water composition based on set parameter standards. These include bacteriological testing, disinfectant residual testing, and physical-chemical testing as its primary parameters, together with iron and manganese content as its secondary parameters. Over the years, MTWD has maintained acceptable level of water quality especially on the primary parameters. However, presence of dissolved minerals even at minimal concentrations naturally precipitates resulting to discoloration of the water served.
True to its commitment to improve its services, the District, thru the leadership of its General Manager, Engr. Miller C. Tanguilan, is investing in infrastructure projects that would further enhance the quality of water. Specifically, filtration systems will be installed in selected pumping stations to remove dissolved minerals. In preparation, a two-storey building is being constructed in Ugac Sur Pumping Station to house a media filtration system that would help minimize or eliminate iron and manganese contents of ground water.
The filtration building is expected to be completed before the year ends. Following the installation of filtration system by next year, ground water pumped from Ugac Sur well will undergo multimedia filtration before storing in the 3,000 cubic meter steel tank built for the purpose. Booster pumps will then convey the water in a desired pressure for efficient distribution of water in the pipe network. The filtration system project is expandable up to 100 lps which can filter an additional 50 lps from its nearby ground water sources.
Filtration systems are the ultimate solutions that will address the natural quality deteriorations of ground water sources. As an initial step of the District to fully improve quality in the water that it delivers, the Namabbalan Pumping Station will be equipped with a 10 lps ion-exchange filtration system. Followed by Ugac Sur Pumping Station other pumping stations are programmed for water treatment system installation.
