PAGSANJAN, Laguna: Besides delivering potable water supply 24/7, Laguna Water will offer desludging or septic tank siphoning for its customers in Pagsanjan, Laguna starting December 2022. Since the beginning of desludging services in Santa Rosa, Binan and Cabuyao in 2018, more than 51,056 households have already been visited and inspected. A total of 8,221 customers have been provided with the service with an accumulated 16,050 cubic meters of septage collected and treated at Laguna Technopark Inc. Sewage and Septage Treatment Plant. In October of this year, Laguna Water completed the upgrade of the treatment plant to include Biological Nutrient Removal (BNR). The BNR project constructed tanks and included additional processes to lower nutrients such as nitrates, ammonia and phosphates to comply with Department of Environment and Natural Resources (DENR) Administrative Order 2021-19, which aims to strengthen the limits of monitored parameters before returning treated wastewater to rivers. The septage or wastewater from septic tanks will be collected and hauled by Laguna Water's desludging trucks to the company's sewage and septage treatment plant. The septage collected will undergo stringent treatment processes to comply with the strict parameter standards of the DENR. Laguna Water's desludging service is aligned with the company's flagship program on sanitation — the Tamang Sanitasyon Equals Kalusugan, Kalinisan at Kaunlaran ng Bayan (TSEK ng Bayan). TSEK ng Bayan centers on environmental services such as sewage management, desludging, collection, transport, and septage treatment. It is the company's share in responding to environmental challenges, including the pollution of water bodies such as Manila Bay and Laguna Lake.
