Once you have selected an iron filter from the options here and placed an order, you still have to install it. You can make some simple adjustments like capacity and salt usage here as well. Usually, it’s necessary to chemically treat your well water to remove the bacteria. How frequently should I check for iron in my well water? Old sewer outflows still visible along shoreline at Warm Water Cove at end of 25th Street in this 2005 photo. Mission Creek's old outfalls now pour into a box sewer, which is pumped south to Jerrold Street. A bigger plant at Phelps and Jerrold processed the waste from the southeast corner, including most of the city's industrial waste. It dried sludge into soil, including that from North Point, notably insulated from wealthy white noses. Even in the 1960s, with growing environmental awareness all around, people pointed out that there were often over 100 days per year when Ocean Beach was too poisoned for swimming.


She points out that if one tenth of the houses in the city had a small cistern system to hold roof and yard runoff, they could save a lot of water during the dry season and eliminate the threat of overflow days to the bay. The resulting precipitated iron (Ferric Hydroxide - Rust) is filtered within the system and iron-free water comes out of the system for use. For many homeowners in the rural area, you may be familiar with the effects of water with high concentrations of minerals such as, calcium, magnesium and iron. But while water softeners can be effective for low levels of ferrous iron, they have several drawbacks. While the godawful sewer system survived the earthquake of 1906, all the sewer engineering records were lost. At the same time that Precita Creek was being turned into the Army Street sewer, London was building the world's biggest municipal waste-carrying system. Dry sludge, or cake, from Jerrold Street was used for years as a fertilizer. And that’s a lot of money to be spending when the comprehensive system warranty is only 1 year (the tank, valve and electronics have 5 years - still not the best we’ve seen).


The control system could be easily operated and it has a very attractive appearance using HMI. The scale of the new system is worthy of ogling. Engineers in London determined the ideal slopes, sizes, and shapes for sewers, encouraging a clear design of smaller pipes flowing to larger, and a gradual slope and steady flow throughout the system. Though some people knew that pipes should flow from smaller to larger, collect, and dump at a chosen location, the unplanned construction typical of a Gold Rush city made disasters like Precita Creek the order of the day. Citizen annoyance combined with federal regulations to force the city to modernize its sewers even more. In 1951, two more plants were built. Seven more years passed, and the city fell down into a shuddering heap of ashes. Combining our cumulative 25 years of experience, we studied user manuals, engaged with customers, got insights from industry gurus, and teamed up with manufacturers. This tunnel, if built, will be a fifteen-foot diameter tube from Jerrold Street in the east to the Southwest plant. Eventually, street and yard runoff will no longer be toxic (if people stop dumping terrible chemicals into the drains) and it will be possible to re-use the water and composted waste from our sewage.


Mission Creek had thirteen sewers dumping into it, making the area stink beyond belief. However, in wet weather, they, along with all the old outfalls at Mission Creek, Mile Rock, Marina Green, Fort Funston, Griffith Street, and elsewhere spewed unprocessed sewage. Worse still, the sewers at Mission Creek, as at the twenty-two other outfalls, or sewer openings, were in tidal water. Some clean water professionals suspect that ocean currents are carrying waste from that pipe to beaches along the peninsula, but there has been no conclusive proof. The outfalls at China Beach and Mile Rock are no longer active, as they deliver waste to the Southwest plant by the Richmond Transport, a big tunnel under Sutro Heights. The Southwest Ocean Outfall is a cement pipe on the ocean floor, which carries waste from the southwest plant. Overflows in the east would not be dumped into the bay, but rather sent by a tremendous tunnel to the Southwest plant. In dry weather, all of these plants dumped primary-treated effluent directly into the bay or ocean.
