Composite verdict
Composite Safety Score: 39/100
One verdict blending 4 independently-sourced dimensions from two separate CPSC systems, each benchmarked against all 838 scored product categories by percentile rather than raw value, so no single huge-volume category can dominate the scale.
| Dimension | Value | National percentile | Weight applied | Source |
|---|---|---|---|---|
| Injury severity (hospitalization + fatality blend) | 7 | 61st | 35% | CPSC NEISS 20-year severity index |
| Annual ER injury volume | 494 | 26th | 30% | CPSC NEISS estimated annual ER-treated injuries |
| 5-year injury trend | -13% | 47th | 15% | CPSC NEISS 5-year % change in ER-treated injuries |
| Consumer incident reports | 1 | 18th | 20% | CPSC SaferProducts.gov public incident report count |
Methodology: each dimension is ranked against the full population's p10/p25/p50/p75/p90 breakpoints and interpolated to a 0-100 percentile; the composite is the weighted average of available percentiles. See methodology for the full benchmark table.

How this 32/100 score is built
The score is computed from four CPSC-derived factors for cisterns, cesspools or septic tanks - no opinion, no editorializing:
- Injury volume 494 ER visits/yr Below median volume
- Severity (hospitalization rate) 7.4% Above median admission rate
- Fatality rate 0.00% No recorded fatalities
- 5-year trend-13%
Band labels compare this category against the corpus of 838 scored CPSC product categories, see the full methodology for the exact weighting of each factor.
What the CPSC Data Shows
Across the 20-year NEISS window from 2005 to 2024, injury counts for cisterns, cesspools or septic tanks are declining by about 13% over the last five years, with the busiest year on record being 2009 (995 estimated ER visits) and the quietest 2010 (175 estimated visits). The single most common ER diagnosis is internal injury to the head, accounting for approximately 505 visits across the 20-year NEISS window, followed by strain, sprain to the lower trunk (477 cases). The 55-64 age group absorbs the largest share of injuries, about 1,743 cases over the NEISS window, and males appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 7.4% of ER visits involving this product end in hospital admission or transfer.
Beyond the hospital-sampled NEISS projections, this page also aggregates 1 consumer incident report filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how cisterns, cesspools or septic tanks fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

Multi-Flo in Lake County Our Multi-flo aerobic waste water treatment system (ATU) has been malfunctioning and overflowing for the 6+ years that we've had it and it was brand new when we moved in. We have spent thousands on this UN-SOUND system. It has been pumped out at least once per year and both pumps have broken at least once and so has the aerator and impeller. When we need a new part it often takes more than a week to get it sent from the manufacturer in Ohio, it's expensive and meanwhile sewage stews in the backyard. The "certified" service provider used to dump sewage in the woods behind the house and because of our complaints and the video we took he was successfully prosecuted and convicted in Feb. 2011. Since 2010 we have had to use an alternate service provider and problems still persist. We cannot afford to keep maintaining this environmentally unsafe machine. The multi-flo "monster" as one service provider (SP) calls it, is a boon to the septic pumpers who earn hundreds each time they come out. Multi-flo has a reputation for being horrible among every local pumper and SP we've talked to. Come to find out it's happening all over Lake County, according to our SP (that we pay $350/year for the privilege of someone to call when emergencies happen - which is about every few months) some people can't afford to have theirs pumped and sewage is running all over the ground on many properties in this beautiful part of Northern California. We have recent footage of a system that was fine for two years and now has been spewing sewage for two months here in my neighborhood: http://www.youtube.com/watch? v=I8NficsP84k Many houses would not have been built in this rural area if multi-flo had not been approved, so someone made money by getting them approved and installed during the housing boom of '03-'05. County Environmental Health Department says it's not their fault; the manufacturer Consolidated Treatment Systems (CTS) them without "trash tanks" (a pre-tan
